Ah, it's time to chill out and get ready for a mediocre q, a live stream if you're old enough grab yourself your favorite adult beverage and if you're not stick with apple juice, put your feet up and relax. If you have any questions, feel free to ask them in the chat and now, let's queue up the intro music hello. How are you guys doing this evening? I hope that you and yours are doing well. I hope that you guys are having you know or, or the holidays aren't too stressful.

I know my wife was kind of having a hard time with some things and she posted on social media. If you guys don't already follow her, i would highly encourage you and or your significant other, your spouses to follow her. It's at hvacr, wife, all one word on instagram um. She commonly posts about.

You know how she deals with the struggles of being married to an hvac service, technician, business owner and all that good stuff, and she talks about the stresses and different things for the people that are just chiming. In i'm talking about one of my wife's social media platforms at hvac, our wife on instagram encourage you to follow her and check it out. It gives an interesting perspective on things now. Remember, there's always two sides to a story right and she tries to be um as open-minded as possible, but she also posts about her struggles and her frustrations.

You know things like how when we have to go out, you know we have to take two cars like to almost everything you know we're going to a family dinner. We have to take two cars, it's very rare that we actually travel in the same vehicle because i'm always worried that i'm going to get an emergency service call. You know this trade is definitely a difficult one to navigate. So we'll talk about that.

A little bit more but welcome to everybody. That's in here uh! Thank you so very much for coming to the live stream. Um a little intro, because i know there's a lot of new people in here. My name is chris and i'm an hvacr service technician here.

In southern california uh i make these videos, i started making them originally for my own service technicians, and then it turned into a whole thing and became this international thing. Where i'm you know talking to people all around the world and uh. It's a very interesting, very humbling experience. I am just a normal service technician um.

I don't necessarily see myself as anything special honestly, i'm probably my own uh worst enemy when it comes to critiquing, myself and stuff. But you know i try. I try to learn something new. I try to share the little bit of knowledge that i have so i got a lot of cool people in the chat right now as usual.

This is awesome, hello to everybody, so we have as usual, if you guys have any questions that you want me to cover or things you want me to talk about. I encourage you to type into the chat, but in caps lock make it all capital letters. That's the way that we kind of differentiate differentiate between questions that people want me to answer and then just conversation within the chat. If you guys are watching this on a tv or something you don't understand, what's going on, i highly encourage you, while watching it on the tv to pull up the youtube thing on your phone and look at the live chat, because there's a whole conversation going on.

Um, sometimes about what i'm talking about, sometimes about whatever you know, whatever any other stuff too, but it's always cool and pretty engaging. So if i for fail to answer your question feel free to keep reposting it until one of my moderators and or myself tells you to stop, and if i miss your question altogether, feel free to send me an email to hvacr videos, gmail.com, okay, my family and Myself, uh cross, our fingers are doing good. We are healthy, um we're getting ready for the holidays. It's the countdown for sure uh.

You know things are a little stressful, trying to get everything dialed in, i believe in talking with my wife. She made the last purchases for our christmas dinner tonight and things like that uh. We do usually untraditional this year, we're kind of going traditional. So i don't do turkey uh, i'm just kind of burned out on turkey, so for thanksgiving we did like a seafood boil.

Um with crab and shrimp - and you know all that stuff - we just have one of those big louisiana-style pans that you cook it outside and then for christmas. This year my kids requested that we do a tri-tip of all things, which is a little odd. But that's a southern california cut, usually of uh. You know a roast that you cook on the barbecue and then also they wanted ham, and you know the traditional potatoes and all that good stuff.

So we're going to go somewhat traditional for our things. I mean our christmas dinner, so my wife was able to pick up most of that stuff. I think we're going to do the other thing we're going to do, which is a little unique for our dinner. Is we're going to do artichokes, so my family really likes artichokes, we'll steam them with garlic and and then we'll cook them we'll cut them in half and then cook them on the barbecue? Actually so uh we're gon na do that, along with our other stuff that we're having.

So i hope that everybody out there is um, you know doing good and hopefully you guys are getting all ready and it's not too stressful for you, like i said earlier so um, let's see uh hvac abc says what trade school or magnet school did. I go to so i went to mount san antonio community college. They have an hvacr trade program. Uh honestly, i never finished the program, i'm shy of two classes, which i know i need to go finish those to get so that way the school gets credit.

For me, it's been many years, but yeah mount sac is what it's abbreviated to and that's where i went to it's probably still considered one of the better community college programs in southern california. They have a great program, great instructors, and you know most of my technicians that have worked for me - also went to mount san antonio community college too. Uh, let's see um there, you go jason johnson says he's stepping it up for christmas, he's going all out on the taco bell menu. That's awesome! So uh.

While we got everybody in here, i want to go ahead and cover this. So last week we had an interesting uh live stream where a good buddy of mine, my buddy rich. I don't know if he's in the chat tonight. I know he was in there in the very very beginning, but we had some very, very generous uh.

Super chat. Donations to the channel and last week what i did was my buddy rich had mentioned that he would be willing to match uh any donations, basically the the same amount. He was trying to encourage people to donate to my channel essentially, and then he was saying whatever they donated. He would match that and donate it to charity, but i one-upped him and went ahead and donated everything to charity from last week's stream.

So it was very cool and i look forward to being able to do that again. Rich and i've already got plans for some time next year. We'll work something out like this and do like a big charity stream or something like that. But i did want to say that i made the donation so last week the the grand total and super chat donations to the channel was in excess of just around 700 and i went ahead and rounded it up myself to a thousand dollars and donated it to The sunshine kids um charity, so sunshinekids.org is the name of the charity that i chose uh.

They help uh cancer, patient or cancer or child. They help children going through cancer to just kind of make it a little bit more comfortable uh to make sure that they're entertained. I did a little bit of research quickly. I didn't spend a bunch of time, but just looking at different charity websites and figuring out, which ones actually give majority of the money and the sunshinekids.org got very good ratings from multiple different websites, saying that they actually donate a lot of their stuff to the kids.

Instead of it going to um, you know salaries and different things like that. So that was the charity that i chose and it was really cool and my buddy rich also donated his agreed amount. He donated a thousand dollars to that charity so uh. Basically, on behalf of hvac our videos, we were able to give two thousand dollars to that charity, so i have to say thanks so much to my good buddy, rich uh.

That was a really cool thing and we totally um yeah. We totally look forward to doing that next year. That's really nice of you alaska, so i really appreciate that, but um all right. So let's see what we got going on in here.

Um. Let me get to my stuff we got going on in here um. So i wanted to talk about the most recent videos that we had. That was uh.

You know the last week we had the reactive maintenance can be risky uh. That was an interesting one, and then i can't cha can't seem to shake the sticky booger off. That was the name of the string or the video so uh both of those videos really had to do with the customers not doing proper preventative maintenance and not maintaining their equipment and unfortunately, that's something. That's happening more and more uh this time.

Right now, it's it's! You know it's hard to make money in the restaurant industry and so they're usually cutting back on routine maintenance and different things like that, and it leads to issues um. So it's it's a pretty common thing. It's just something we have to learn to deal with, and i'm going to talk about that a little bit more in here. I've got a whole list of things i want to talk about and then definitely want to get to more of the questions in the chat too so um, let's see what else we got uh.

I really appreciate that samuel. That is an amazing donation. I much appreciated, but okay, so um. Let me see uh so in my recent video that was, i can't seem to can't seem to shake the sticky booger off.

Okay, that video was a return visit to a customer that i have previously changed a compressor on and in the video this time we had an evaporative coil that was iced up uh. It had a fan, speed controller that had failed and i did not do anything but bypass the controller. Let me explain a few things in there. I am not in the habit of bypassing things just to bypass them.

Okay, i can only do what the customer's willing to pay me to do. Okay in that situation again, i can't go into crazy detail right now, but that particular customer didn't want to spend any more money than he had to um and he just wanted it fixed and back and working as fast as possible. So um, i was suspect of the fan, speed controller in the beginning, but then it seemed like it started to work. I thought i found an issue where the thermistor came loose and i do not like anything about that system, but i went ahead and found that the controller actually was faulty now.

Was it just a controller or the thermistors bad, it's hard to say, but the customer didn't want to do anything else with it once i explained everything to him, he simply said just make it work. I don't want to replace anything. So i was able to just bypass the fan, speed controller and get the fans to run on full speed. Now i do want to address things first off that customer did not pay for that fan, speed, controller or any of the evaporator fan motors in either of the two evaporator coils that was paid for by the local utility as part of a rebate program or whatever.

It's basically paid out of our tax dollars. They go in with the local utility. They want to incentivize people to do energy efficiency upgrades to their places, so they pay for things like on the commercial setting. Evaporative fan motor replacements, ecm motors plastic fan blades.

All this weird stuff, okay, so um, honestly, i'm gon na tell you guys that if the customer had to retrofit his own equipment and install a fan, speed controller, replace all the fan motors go to two-speed ecm motors and all that fancy stuff. They would not do it because the the the return on investment is not there. The the failure rate of those motors, the the the iced up, evaporators that they run into with those two speed motors and stuff. It just becomes a problem, so i want to talk about those istep evaporators too.

On those evaporator coils. That's a air defrost, medium temperature box. We need those fans on high speed. I had a few people in the comments saying: no, you want the fans on low speed, no, you don't you want them on high speed and then i also had some people saying that you know you want them on low speed, so it doesn't blow the water Off the coils, well, there's a problem: if you have that much water on the coils and you need to solve that problem, these evaporators were meant to run with the fans on high speed all the time, so that way they can defrost appropriately.

If they wanted to. You know run them on low speed. They really should design them with a bigger fins per inch design. So that way the spacing between the fins is wider.

Then they wouldn't get as much condensation blowing off in those situations, but that's a whole nother issue that you have to deal with because you could lose efficiency when you do that and stuff like that. So you know it it's kind of a bummer when you come into these systems and they have all this uh. You know fancy energy efficiency stuff, and then you know the customer doesn't want to fix it and you end up having to bypass it. Of course, i want to replace the energy efficiency stuff, i mean think about it like this guys, i'm a business owner if i want to make money right and the customer has a bad part that they wanted installed some energy efficiency thing.

Of course i want to change it right, but in all reality you know i mean if the customer asks me my honest opinion, i'm gon na be fair and honest with them and tell them like. I don't think it's really worth putting this stuff on there, because majority of the time the return on investment just is not there. Okay, so you know you can go without what you want so um. Let me see what else we got going on here.

Kevin schmidt says that his family wanted brisket. You know i thought about cooking a roast of some sort, but i don't know i just didn't really want to go that far with it um. I was gon na alaska, again man uh nate peterson. Thank you very much for that super chat.

Man. You guys in these super chats is amazing. Uh, you guys are awesome. It's very humbling that you guys would consider donating like that.

So it's really cool um. Let me see what else we got going on here. Let's see uh the fans and heaters yes, and that decision is not the text to make. That is true.

You know it's it's all up to the customer and what they want to do so um for those that celebrated. I want to say merry christmas to everybody out there. If you do not celebrate it, happy holidays, um. You know this is a a time of year when i really think especially right now, we need more kindness, so it's very important.

Okay, uh. Also, let's address that. One too, so, if you guys didn't already see it, i released a video last week. Uh, i think it was last week was the kindness video last week.

I think it was anyways. I released my kindness, video and uh. That was something that i wanted to do. I don't think i really talked about that yet.

So that was something that i wanted to do for a while. It was a big secret that i've been keeping all year and what i had done was. I asked a question on my social media. You know if anybody had done any random acts of kindness.

Did it a couple months ago and uh we were able. I wish i could have picked more, but we were able to pick 20 people that have answered my questions between my platforms and all my friends that had also posted it and we picked 20 people and we all uh between myself and true tech tools. I put in 6 000 true tech tools put in two thousand dollars, so we were able to have eight thousand dollars in gift cards, so we were able to evenly divide that up so 20 lucky people got 400 gift cards to true tech tools. So that way they were able to purchase whatever tools they want within that amount.

So it was a really cool thing to be able to do, and i hope to get to do it again. Um. I again, i can't remember if i talked about that last week or not or might have got overshadowed with the whole super chat thing last week, but but yeah. That was a really cool thing to be able to do, and i have made contact with everybody um everybody actually accepted the gift cards and majority of people have already used them.

One person actually i'm in contact with him right now talking back and forth, but he actually is uh. Well, i'm not gon na announce that yet but anyway, so we'll get to that um. Let's see what i miss uh in the chat uh have. I ever had an ac that i couldn't fix, um yeah, i mean we usually bring it up to the customer and let them make a decision on whether or not they want to fix it.

You know, sometimes i mean. Is it a matter of? Could i not figure out what was wrong with it um? I don't think i've ever had an ac that i told someone else to call someone else, but i have had acs that the repairs were so extensive that customers, i basically just told them, just replaced this thing. You know stuff like that. So um, let's see laska's saying that he's making apple pie.

So actually in my house i make it's like a family tradition. My my grandmother used to make it then my dad started making it, and now i make it it's actually a cream pie um and it's a little different because it's kind of a it's hard to say it kind of tastes like you're eating a big sugar cookie. I guess is the best way to describe it: it's a vanilla, cream pie, it has a standard pie crust and it's super yummy. It's not it's not custard.

It's not pudding. It's. It's got a thick consistency and it's just a very interesting, unique taste and that's a tradition that i probably will be doing this christmas is making my cream pies those usually take you you make the pies the day before you let them sit. Then you do a meringue on them.

It's kind of a fun thing. That's turned into a family tradition, so i'll be doing that. Let's see what else we got going on in here, um at the end of the sticky booger video. What was that really? Oh? Was it really a house fire honestly um? The last clip that i showed when the hook and ladder truck was pulling up, the fire was already out whatever it was.

I don't think it was a house fire because it wasn't coming from the eaves of the house. You guys only saw little clips, but i was up there for a while watching that smoke. I honestly think that someone was like uh. They had maybe had a grease fire and a barbecue, or something like that.

That's what it looked like to me because it smelled like someone was barbecuing food, the whole time. So there may have been a grease fire in a barbecue. It wasn't a car fire. There was never black smoke, it was always white smoke.

So it's interesting. I don't know what it was, but the house was did not burn down or anything like that. The fire trucks were probably there for a total of 20 minutes, so they were, they were in and out so the the homeowner or the tenant of the house must have already had it out by the time the fire department really got there. So, let's see what else um did i find out any more information already.

I already said that in that one i already answered that one um yeah. I will definitely try to take some family time um all right, let's see what else uh. Of course, i make cream pies during my pineapple alaska. I'm not gon na read the rest of that one, that's funny um, so uh.

I wanted to share something with you guys, uh. You know with everybody, that's watching right now and then i've got a couple more things i want to cover. I know i have some things i told people i'd talk about, so i just kind of want to talk about the state of the channel and where things are going, i was sending some emails out today to uh sponsors and people that i work with and stuff With the videos - and i just kind of wanted to address things on the channel too, no big changes are happening or anything like that. But i just kind of wanted to say what my future plans are with the channel for this upcoming year and hopes that you guys can hold me accountable for this stuff too.

So um number one. We added a lot over this last year, we've added several more social media, um platforms to the hvacr videos brand. So with hvacr videos uh, i am active now on uh ticktalk facebook, youtube instagram. I have a twitter and a linkedin all on hvcr videos, then uh.

We do plan on pushing the hvacr tools platform a little bit more this year, so hvacr tools is a platform that my friends and i are doing and we're doing tool reviews, but with a twist kind of like our way, we've done a few of them, but We've kind of like petered out a little bit because we all got busy, but i plan on on focusing on that a little bit more uh. Obviously my wife started a platform hvac our wife on instagram there's also a facebook page, but she hasn't posted anything on facebook. We do have some future plans for that. That's where she shares about her daily struggles and daily life and how she deals with things.

It's a great community for spouses to get together, but i also notice that on my wife's platform in the comments, there's also several technicians that also comment wow, i didn't realize my wife goes through this too. So it's a great place for um, both the technicians and the spouses to interact and see you know and communicate with other people. It's a cool little like-minded group of people so check it out. Uh also potential future plans is uh.

You know to maybe start a podcast. That's always been something that i've wanted to do. I actually already have a name. A very unique name picked out, i'm not going to announce it yet, but it's out there.

I think i might have mentioned it before, but the podcast is something that i might be doing. It'll be an interview show a little different than the overtime thing more serious, but just just a different twist on it. So that's something that i potentially want to work on, and i also have been reaching out and announced on social media too, that i planned on hiring some help to help me with it and all that stuff. So stay tuned with all that stuff.

It should be cool um. What tool video ideas do i have? Oh, i have all kinds man, but i'm not going to go too far into that right now i want to get to a few things that i said i was going to talk about. Okay, so um wilfred wilfred is from the netherlands and uh. He had asked me a question and i get a lot of these questions.

Okay, so i i have international viewers and i tend to get these from the european viewers more than anywhere else in the world. Why in the heck and how can i ethically still use r22 404 and all these different refrigerants that are banned in the european countries? Okay, so, first and foremost, to understand for the international viewers here in the united states. It is not illegal to use r22 okay. It is illegal for a manufacturer to produce brand new r22 in the united states and it is illegal for anybody to import brand new refrigerant r22 refrigerant into the united states, but we have a massive surplus of it and we can also use reclaimed refrigerant.

So the refrigerant that we recover out of the r-22 air conditioners and we take it to the supply house, they refine it. They clean it. They re-uh package it and sell it to us again, and then we can reuse that so you can still use that r22. So why do i still use it? Is it unethical for me to use it? I don't think it's unethical for me to use it uh.

I definitely know that, if vented to the atmosphere, it can be bad for the atmosphere for sure, okay, but uh. We're still able to use it, but the expense of it is getting ridiculous. The prices are going sky high same thing with 404, 404 is being phased out. Any 400 series refrigerant for that matter is being phased out.

448. A for insert. You know flavor here. All of them are being phased out.

Eventually, they all do something bad to the environment. So um, it's just you know we're still working our way through the phase out of those refrigerants, so you're going to see less and less of it. There's a push to get rid of 404 here in the coming future. California, 404.

A refrigerant is already being phased out, meaning that you're not allowed to use it on new installs, major retrofits or anything like that. So it's all being phased out, but you know it's just a slow process to get to that point where we're going to eliminate it completely. Okay, um jesus uh tapia asked what brand i want to go with my home air conditioner, because i have been talking about upgrading my home ac system and he's curious. What brand i want to go with honestly.

I am up in the air on what brand i want to go with. I've gone in bunch of different directions. In my head, i've thought about going multi-zone mini splits. All throughout my house.

I've thought about going um. You know full communicating, uh, spaceship status controls and things like that. I've thought about doing a total hybrid system that i made myself dual fuel, not that i need it, but i mean i've thought about doing it all that different stuff. I've thought about going all electric all gas.

I i'm all over the place. I've thought about putting in a crazy inverter system. You know we're doing a half inverter system with like a whatever brand, where you can buy just the inverter condensing unit and you know, use whatever evaporator i've. I've gone all over the place.

I really haven't made a decision yet eventually i will work on that. So, let's see what else we got going on here, um, what am i missing in here? All right cool, nothing yet so uh next question: i had a really interesting email and i want to address this - a gentleman named ian reached out to me because he has some very interesting filtration questions, now ian fully acknowledged in the emails that he realizes that i'm Not an expert when it comes to the world of high-end residential air conditioning systems. I have general knowledge of it, but he fully acknowledged that in the email, okay, but he was very curious on the commercial side about air filtration and different things like that. So ian has a major uh issues where he needs extremely clean air in the home.

I'm not going to go any further than that and he's having a new construction build done right now and he was asking me about hepa, filtration and different things like that and uh. I i immediately emailed ian back and said: look here's the deal because i read his email incorrectly. I thought he was just asking about air filtration. He was not, but i want to address something right now for because i get a lot of homeowners that watch these videos too, and i want to address this okay, first and foremost um.

I am not a believer personally in in these gimmicky style, air, cleaner machines and ian's - not asking about that, but i'm just making this a whole question: i'm not a believer in the gimmicky air cleaners and all these different, weird uv lights and different things like that. Okay, i'm a believer in fresh, clean air, i'm a believer in filtered air and i'm a believer in solving infiltration issues in your house. So that way you don't have to worry about filtering so much of the air, okay um! So that's that's. Let me say that from the beginning: okay, i'm not judging anybody.

If they, you know, use these air cleaners, these uv lights, these, whatever things? Okay, it's just not my style of things, i'm a believer in fresh, clean air and going from there. Okay, so, first and foremost - and this is where i thought ian was asking me a question, but he actually wasn't, but i thought he was saying that he had an existing home and he wanted to put a massive air filtration system on it. So the original response, email that i sent to ian was dude. Let's address your envelope.

First, okay. Basically, let's look at the home. Let's do blower door test, let's find where your infiltration problems are. Then, let's correct those then go down the filtration path and the reason why i bring that up is because, if we have a home that is leaky and has a lot of leaks, if you put a massive filtration system on there, it's just going to be spinning.

It's wheels trying to filter all that air as it's sucking it in all the cracks of the house. Okay, so solving your envelope problems sealing up the house making it. You know tight right so that we don't have very much air leakage. Then go about addressing your your filtration problem, so then i reread ian's email and i realized he was doing a new construction.

So this is a brand new build and he's got engineers involved that are telling him that he should look into humidifiers and all these different things, which are all good things, because the location that ian lives in and i'm not going to reveal that either. But the location that he lives in is in an area that has a lot of moisture content in the air he's going to need to think about dehumidification he's going to need to address all those issues. So i think it's very important that people understand before we go into the home and try to just slap an air conditioner on it. We need to look at the house itself seal it up, fix the issues and then look at replacing the air conditioning system solving filtration problems, and things like that, obviously, and ian again understood all of this okay, so um next next thing uh.

If anybody out there is an hvac contractor, and i've already reached out to some other friends of mine too, but feel free to send me an email if you're an hvac, a high performance, hvac contractor for the high-end residential systems in the bay area of southern california, Send me an email to hvacr videos, gmail.com and uh, if i deem it appropriate. I will get you in contact with ian because he is looking for a little guidance in this situation, but we are looking for high-end, residential um, cus or companies. Basically, okay, we're not looking for people that are just gon na throw a system at it and say this should do it! We're looking for someone! That's gon na prove that it's gon na do it and then after they're done they're gon na guarantee their work and then prove the results too. Okay.

But i've also reached out to some of my other friends too. That'll, hopefully get us in contact. So but it's very interesting and we always need to understand that before we start just throwing things at the house, we need to address the issues. Why do they need so much filtration? Is it truly because they have issues or is it truly because there's just massive amounts of dirty air coming into the home? There's mold issues and different things like that? So if we solve the home problems, the air leakage problems, you know we may it changes the way that we address the problems in the filtration.

So let's see what we got going on in here, ervs and hepa, and that's actually what ian was asking me about. So um uh micah says: what's my favorite ac unit to work on uh personally, my favorite air conditioning system to work on would be a lennox commercial package unit. I love working on the linux units um, i'm comfortable working on the carrier package units kind of okay working on the york package, units kind of okay working on train package units, but my favorite would be the linux honestly. The ogl series linux units were my favorite.

The prodigy 2 is a nice control strategy. I know linux is getting rid of prodigy 2 and they're going to their new one. I can't remember the name of it. I've watched the videos on it.

If you guys haven't seen it. It's very interesting because it's all off your smartphone, very, very interesting system, so uh, let's see what else we got going on in the chat. Um all right. Nothing else, aeon hands down is what tyler says.

That's really cool um nj workshop says r290 needs to be phased out immediately too many leaks, i wouldn't even say the problems with r290 i'd say the problems with the poor craftsmanship of the manufacturers that are not putting this equipment together right. Another thing to understand, too: is manufacturers are cutting back because of the lower pressures of r290 they're, changing the the quality of copper that they're using which is leading to issues? This is all, in my opinion, by the way too, but i'm noticing that the quality of the copper that they're, using in the new refrigeration systems that they're new using r290 with um, is not the greatest quality, copper, either and uh their braised joints are, you know, Just just horrible, so i get brand new uh refrigeration systems from all different brands that come with no refrigerant in them from the factory that are completely missing a weld or the welds are goobered up and not even done. They look like they were done by you know, whatever i'm not going to go any further with that one, but um all right. So i answered that question.

Let me cross that one off and let me cross these other questions off. So i have a list of questions in front of me that i go through and i answer as we're going through and i already i talked about that one. You know i get a lot of questions about this. Why, in the heck, do i change so many compressor contactors when i'm working on things guys, because they're low hanging fruit, constantly compressor contactors are one of the highest failure, things that i run into on refrigeration systems and air conditioning systems.

So i always attack the contactors, because when you look at them i mean the thing is: is what's the point at when a contactor is good or bad? I mean it can change. Sometimes contactors can be 30 years old and they last forever, but it also depends on the the when they were made to the era that they were made in older contactors made in the 80s 70s and early to mid 90s. They lasted a long time. They were using high quality materials, but anything after that they became throwaway items, they're, not rebuildable anymore and they're, just junk and uh.

You know, there's there's a bunch of different things they can do. You know i get questions from european countries all the time. How come we don't use totally enclosed relays? You know like other countries and stuff. That's a good question.

I mean you know if it became mainstream and the price point was right. Then, of course, i'd start using those things, but you know they're not readily available at local supply houses and the price point just isn't there to use totally enclosed relays. So, let's see what else hepa only works if the velocity is 80 to 20 feet per minute. 80 to 120 feet per minute: opal velocity must be 60 to 75 and he's saying different velocities.

So another thing to understand too. Yes, when it comes to filtration such as hepa, if you're going to go that fine, you know and get super super low on the filtration, uh particle count, kind of stuff or whatever um. You need to understand that it's not just as simple as throwing a hepa filter in line with your existing air conditioning system, no help of filtration systems typically going to be designed. The air conditioning system is going to be designed around the filtration system and the air delivery system for sure.

So we are talking serious engineering getting involved and we're not talking small potatoes here. This is going to be big budget jobs that you know people are trying to solve real problems. Um, let's see what else we got in here. Uh, yes, uh, rita, loy, says line contactors used to use silver and they did you know they did used to use silver um.

You know, and it's it's very interesting what the the materials that people have gone down into um. Oh yeah, we've had that happen too. Jared says: he's gotten new linux units that didn't have economizers and things a lot of the times that comes into the ordering process. But yes, i've gotten that before too uh.

What do i recommend for a smaller veto? Bag? Um i've got this one sitting here. This is the veto. The names are silly tp xxl, whatever um i've used it a few times, it's a little big. For me, it's kind of neat having the meter stuff on the side.

This is a pretty popular small bag. A lot of people you can keep quite a bit of stuff in there it's different than the tpxl. I had the tpxl, and i gave it to one of my other technicians because it was too small for me. So i got this one.

This is a very popular one, but i will say, with the base: they've made it a little bit wider on the bottom, but it still can be subject to tipping over a lot as uh norcal dave calls the tpxl tippy. This one does a little bit better, but it still tips quite a bit uh. That would probably be my recommendation as the tpx xxl for the smaller form veto bag um. All right, let's see what else we got going on in the chat, how's luke the lab doing and how much bigger has he gotten uh here in a little bit i'll? Have my family's not home right now i'll have my family bring him in and i'll show you guys he's getting huge, so um all right, uh chris m says thanks for the videos.

Thank you chris for watching and all you guys the support i have to say thank you to all you, people watching right now, because the support and the views that you give me um on these videos is what makes me continue to do them uh. You know whether it's just watching leaving an encouraging comment, giving a thumbs up uh. You know to monetary support, financial, all that different stuff, it's amazing. So it keeps me going and thank you guys, all so very much for all the support of all different kinds that you give.

Okay, let's see what else we got going on in here: okay um! Why is it that in california we don't use heat pumps more? Okay, i get that question quite a bit. Actually, why the heck would we use gas heat uh? We don't use heat pumps because it's it's there's a lot of issues with the heat pumps that goes in number one. I'm going to tell you one of the most obvious reasons why we don't use heat pumps. A lot is because heat pumps require a different mindset when you're working on them and to be fair, a lot of people don't understand, nor have the um the patience to work on heat pumps.

Okay, a lot of people are afraid and scared of heat pumps. There's there's more thought process that goes in, and it's going to take some time to get used to them. One of the other reasons we don't use heat pumps very much is because we have a poor energy grid. Now, to be fair, i say that all the time california has horrible power all that different stuff.

Okay, you have to understand that we have a massive amount of people right, we're one of the biggest, if not biggest populated states. In the country i mean we have a crap ton of people here and we have a crap ton of people moving here on a daily. So you know we have a very unreliable energy grid here, there's a lot of political and technical issues that go into the horrible energy grid. We got rid of our nuclear power plants.

We had two of them up until recently. Those are both being phased out. We rely on our power coming from hydroelectric power is one of the most common places and also burning burning fuels, basically burning uh, propane and different things like that are natural gas or natural gas. I should say uh.

We, we burn natural gas to uh, create electricity. Also they're trying to phase that stuff down so in phasing the natural gas burning down we're reducing the energy coming into the grid. Also - and i know, there's a lot of technical issues that go into this too, but also we get a lot of our power from hydroelectricity from the hoover dam uh and a lot of that. We are in a massive drought, they're restricting the water they're running into issues with that.

So we have a very interesting energy grid and a lot of weird interesting problems here. So you know they've never really pushed heat pumps as much and we've always done gas, but now they're, phasing out gas, so heat pumps are getting more popular but at the same time we're still having the electricity issues. So it's an interesting dilemma. We have but a lot of people just simply can't work on them.

So uh, let's see, let me see what else we got going here: california going to catch on fire if they start using heat pumps, yeah, that's true, uh speaking of contactors, any experience with the sure switch uh. No i've never installed a sure switch. I actually have one sitting in my garage that i've been meaning to put on my home air conditioning system for years. I just never did what do you guys do with the phased out phased-out refrigerant you have recovered when we have refrigerant, we just take it to the supply house.

They send it off to the reclaimed company, which essentially just cleans it and then resells it. That's what i do with it. So am i still in a chevy van. Yes, i still use chevy vans and i'm going to continue to use chevy vans, the last true van out there.

Everything else has gone to the euro vans and i've heard nothing but problems on the euro vans, so i prefer the chevy van i'm going to hold out until they eliminate them completely. Um. Let's see jason johnson said he was part of the crap ton that moved the living hell out of here. Life is much better, not living in the state.

That is true. Uh did i hear no new gas hookups in new york electric only dave k, yeah they're, also saying that in the northern california area and some of the fancier climate areas they're eliminating natural gas berkeley is one of the really yuppy cities and they've completely phased out Natural gas on new installs and stuff, so it's very interesting. They want us to rely. I mean again, i'm not a i'm, not smart enough to understand all the political crap and everything.

But it's i don't know. I don't know where this is going. They're phasing out generators now uh generators, gas, lawnmowers leaf blowers on commercial, whatever they're getting rid of all that it's it's very interesting. I get it i mean i want to.

I know they want to save the environment and stuff. Let's see uh valactic says: are there better options than contactors in terms of longest jv and reliability? Well, you have totally enclosed, contactors and or relays such as, like the sure, switch and things like that that can prevent a lot of the carbon buildup that you get from a contact. That's in the open air just sitting there pulling in and out putting in and out, you can have hermetically sealed, contactors and things so i'm sure, there's good stuff, um yeah, only one nuclear power plant in california, diablo canyon, yeah and they're they're talking about phasing that One out too, aren't they rita lloyd. I thought yeah because they closed down san onofre power plant, which is was local to me in southern california.

They've already closed that one down and they're. Currently, in the phase down situation of that one um, let's see what else we got going on here: illegal to smoke in public in berkeley, yeah, there's a lot of different rules, it's illegal to smoke in a lot of places in california, actually in public, all right. Um, so i wanted to address something, and this is an interesting perspective. I get a lot of emails from people all the time, okay and one of the more common ones, and it's very interesting - and sometimes i have to question like why do they keep sending me? These emails, i can't tell you how many immigration requests i get and that's a very interesting dilemma.

I get emails from people all around the world saying i want to learn hvacr. Could you please train me? Would you help me to learn how to immigrate to your country and, unfortunately i have no idea how to help people with any of that stuff and that's just a big thing, but what i wanted to reflect on that one i wanted, and i've been thinking about This and you know i try not to get too crazy on this, but the point i want to make is you know here we are in our country and i'm not saying we shouldn't be upset about this stuff, but i'm just saying: let's take a step back And look at this okay, we are so worried about ourselves. We are so worried about crazy stuff going on in our country and while we should be, we should pay attention to our own country. It's just an interesting perspective to think about how many people out there would love to live here.

You know, and sometimes i have to remember that stuff - and you know it kind of puts things in perspective - to remember that there's people all around the world that would give their right arm to move to america, and here we are fighting over some petty things here. So just kind of gives me perspectives on things. I wish i could help people with the immigration requests and stuff, but i have no idea how to do any of that. But let's see what else we got going on here is there a certain fan motor for the linux units? Uh, i mean you always want to try to stay oem.

You know within the manufacturers so yeah with the linux condenser fan motors, there's oem specific motors that are designed for the linux units yeah, you can make aftermarket work but you're just going to have to play with things and change things and rewire things and stuff. So um, let's see um, so i also wanted to talk about and i get this one a lot. But someone recently sent me a comment on this. In my recent video i talked about sight glasses and i did a pause and i talked about how sight glasses need to be clear on refrigeration systems with expansion valves.

I say this all the time and i'll say it again. If you have a refrigeration system with an expansion valve, it is supposed to have a solid column of liquid going to that expansion valve. That's the way that expansion valves work, expansion valves, don't do a good job when they're feeding vapor they do a good job when they meter liquid refrigerant and turn it into a vapor liquid mixture. Okay, there is a point at which you can.

I have seen it happen. You can have an expansion valve that can kind of work when it does have vapor going through it, not a solid column of liquid. But it's not right. Okay.

But the question or comment that i had recently was someone saying: yeah, try to clear a sight glass when you have a very, very small tin, can receiver on the roof and the line set 75 feet long, there's just not enough storage capacity in the receiver to Be able to clear the sight glass - and there is truth in that statement, but understand something systems need to be designed right and we, as technicians have a duty to make sure we inform the customers when their systems are not designed right, uh, the 98 deville. Thank you so very much for that super chat smash the thumbs up button. I really appreciate it. You are awesome: okay, um, so uh.

You know it's important to understand that if a refrigeration system is not designed properly, that is sized properly the refrigeration line size properly. The receiver, the condenser and everything is sized properly. Then there's going to be repercussions. If you try to use an off the shelf, half horsepower condensing unit, that's meant for indoor locations and put it onto the roof and just run a remote line set to it.

You're going to run into problems majority of the time because the receivers are meant to be, it's meant to be. You know. A two foot line set run not meant to be 75 feet, so we as technicians have a duty to let our customers know when things are not designed right. It does happen that you go up to a system that you cannot pump it down at the receiver.

You cannot front seat the receiver's king valve and expect all the refrigerant to store in the receiver and the condenser on really long line set runs because they weren't designed properly. If the system is designed properly, if we've installed receivers that are big enough, you should be able to pump the system down completely and store the whole refrigerant charge in the receiver in the condenser okay. So there is truth in the statement from the person that commented about how you know it can be a pain to clear sight, glass, but understand that if the system is designed right and for it to work right, our expansion valves on refrigeration systems need to have A solid column of liquid going to it for it to work properly. Okay, so you know i i we have to remember that stuff and we, as technicians, have to pay attention to that.

You know my videos are not meant to replace a proper education. A proper education is going to teach you the things you need to do. My videos are a supplement to someone's education, okay or someone's. You know technical skills they're just there to supplement.

I do not put all the information in my videos to explicitly teach people from point a to z. You know how to do things: um, blue on commercial, that's funny, um, all right! Uh, let's see uh what is the process most effective for troubleshooting, refrigeration, walk-in cooler and freezer jose? First off before you start to troubleshoot them, you need to understand the sequence of operation of said piece of equipment doesn't matter what you're working on you need to understand. How it's supposed to work when you turn on the thermostat or the temperature controller? This happens, then this happens, then this happens. Okay, understanding that, first understanding, if the system was designed properly, someone sent me an email or a comment or whatever.

I don't remember where, and it said. How am i supposed to know what refrigerant pressure should be depending on what flavor of refrigerant right, because we have so many different flavors, so many different types of refrigerant? What should the pressures be? Well, that is a very vague question and i can't really give you a informed answer without knowing a lot more details. You know we need to know how the system was designed all right, uh clint glasgow. Thank you so very much for that super chat that is amazing and it and i'm i'm humbled by it.

Thank you very much for all the support. Everybody you guys are awesome, so you know we have to know how the system was designed. Now that can be tricky, so we will. You have to use some rules of thumb in evaluating things, but you know people ask me all the time.

Well, you know when they're looking at my refrigerant pressures - let's just say this: okay, let's say i have a refrigeration system and i'll give you guys an uh details about this example. But i was working on a refrigeration system this weekend or ju this last friday and it turned into a disaster. It's gon na be a video eventually, but it was epic. It was huge.

It was a pain in the butt, but when i went to go start the system up, i noticed that the pressures were not right and they just seemed really really low. On the suction side, the evaporator temperature was really low, but something to consider was this location was out in the southern california desert. It can be 115 degrees in the summertime, so they size the equipment for the extreme ambient conditions. Typically, so, even if they didn't size it for 115, let's just say they sized it for 105 degrees.

Okay, it is a three horsepower condensing unit, all right at 115 degrees. A three horsepower condense unit is only going to put out. You know, let's just uh, let's say i don't know 30 000 btus. I don't know you know, i mean it could be just a number but to understand the point i'm trying to make in the high ambient conditions it's going to put out a lesser amount than in the low ambient conditions.

The low ambient conditions that condenser just gets bigger and bigger, because now it's massively oversized when a condensing unit is massively oversized that can affect the performance of the evaporator downstairs. So if they were designing it to run with a 10 degree td. But now you have a giant compressor on the roof that is just pulling that refrigerant back up and the refrigerant doesn't have time to do the proper heat transfer in the evaporator you're going to have efficiency issues with that equipment. Okay - and that was part of my problem, so it's important for us technicians to understand you know, what's going to happen to a system like that particular system, because it has such extreme temperature swings in this desert climate that i'm talking about.

They go from 115 degrees. In the summer to 25 degrees, lowest temperature, maybe 20 degrees in the winter - and that's an extreme temperature swing right there and the efficiency of the unit is really going to change. And it's so important to understand, too, that we're going to have to have capacity, control and different things like that. It would be a perfect situation for, like a digital scroll, compressor, that's going to unload and slow down in certain ambients and different things, but they don't have that they just have an off-the-shelf refrigeration system.

So you run into issues so understanding things like i just explained. Knowing that it's not always going to be perfect and how to compensate appropriately for that is very important. Okay, let's see what else um, let's see micah he's saying i pretty much only use oem replacements yeah. I typically try to stay oem as much as possible.
