Ductless, mini splits, do not operate like conventional HVAC units. In this video, Joshua discusses the biggest mistake, most ductless owners make when operating their ductless mini split. Why is this such a big mistake? Humidity is the main reason. Most ductless unit owners are not as comfortable as they should be when operating their air conditioning. Josh discusses why this is such a big mistake and how to remedy it in this video.

Do you have a ductless Mini split? whether it's a wall? Hong or maybe some other type that has a remote control controlling it. not like a thermostat, but one of the actual remote controls. One of the things that I see in the industry probably more than anything else. As far as people that are not using their system correctly and that could be for a number of reasons.
I Feel like a lot of our homeowner customers, they don't really understand the capabilities of their system. They have never really read the instructions. Because of that, they at times are not necessarily using their remote control correctly and so I wanted to do a video on the probably number one thing that I see homeowners doing incorrectly the most more than any other thing I see homeowners all the time running their system on some sort of fan setting wide open and I think there might be times when you want to do that, but more times than not, you you want to find out. I'm not necessarily going through the exact symbol.
I Mean we might show that symbol right here. Just realize depending on the brand you have or the type of system you have, that symbol might look different more times than not. Your fan settings and the mode settings should be on auto for a ductless mini split. Mini Splits Unlike a conventional system, most conventional systems, you have a temperature.
You put it in a certain mode and you set that temperature and that system. If it's a single stage or multi-stage unit, it's going to run until it meets temperature and then of course inverter systems can ramp up and down until it meets that temperature, but with many splits, you are taking the inverter technology, the ramping up, and ramping down variable technology away from that system. When you are setting fan speeds and adjusting those sorts of things, you want that system to have the ability, the freedom if you will to you, put it in the mode you want, you put it on the temperature you want and then put everything in Auto and let that thing ramp up, ramp down. It'll run more efficiently and it will run like it was supposed to like it was designed to.
The reason: I Think this is probably the biggest issue that we see more than any other for two reasons: Number one: The inefficiency aspect. When you are telling that system that you want it to run at a 100 capacity. For example, you are making that system run more like a single stage system that's gonna blow and it's going to cool down that space really fast and then it's going to shut off or at least ramp way down. so it's just super inefficient.
But the other reason it's a problem. We've actually seen this. We've had customers that whether we installed their system or not, we've had customers call us and they'll say something to the effect of I'm seeing mold I'm seeing some sweating in a room I'm seeing some stickiness or feeling some stickiness in the room I Remember one of our customers actually she had a bed in that particular room. It was a bedroom. go figure. it had a bed. It was a better room but you would touch the bed spread and it was just kind of like sticky feeling. very humid, clamminess, sticky feeling on that bedspread.
And the reason we found was she had had her adult son who came into town. He did not normally live with them but he was staying in that room and he was using the mini split like he would his car like. in your car you would turn your temperature the old school cars I'm not talking about the new ones that you can set a temperature, but at Old School you'd have a like a little dial there of some type, maybe a twisty dial and you would set it and turn that fan to whatever setting you want and cool yourself down on a hot summer day. Well, Mini Splits will have issues.
If you're doing that, you are taking away what it was designed for in a lot of cases, probably more than anything else on the market. We see many splits installed oversized in rooms all the time with some Brands The smallest mini split you can buy is half a ton. You're looking at six thousand, seven, 1000, sometimes even 9000 BTU units being installed in bedrooms that really if you were to do a proper heat load calculation for that room, the cooling needs for that room would be minimal. I Mean we're talking like a thousand BTUs maybe needed for that room And so if you've caught this video, if I could give you any advice, I would give you two things.
The first thing is: put that setting on auto always and about 90 percent of the application. There might be a few scenarios that you might not, but ninety percent of the time I Want that remote control to be an auto and almost heating two I Want that system to have the ability to ramp up and down as it sees fit, run efficiently, and then also remove humidity from that space by ramping up and down in the summertime correctly. But the other piece of advice I would give you is just take a moment and read the instructions. Read the owners or users manual.
Understand what each one of those little symbols or buttons does. You would probably probably save yourself a lot of headaches, and honestly probably be a whole lot more comfortable in your home. You might have significantly cleaner air if you were to read those instructions. I've had customers not understand that number one: how often they should be cleaning the filter, How they should be cleaning the filter I've seen people using fancy cleaners or stuff that they're not supposed to and not realizing they're actually causing more damage than helping.
And so again. I Would just recommend reading those instructions. You might have a carbon filter on there and you can't get it wet or whatever. Whatever the scenario is, you won't know those things unless you as the customer as the homeowner.
Take a moment I Know you would expect your heating and air guy to take a minute to teach you all these things, teach you how to use the remote, but some cases maybe they did and just didn't remember it. or maybe they didn't know some things themselves. Maybe there are certain things that you're going to read in that manual that even your heating and air guys never taken a time to read, so that would be my parting advice. We read those instructions, use that remote correctly, put that thing in auto mode, and enjoy the technology that. you've paid for the high-end inverter variable technology that a lot of these mini split systems have. so thanks for watching Hit that subscribe button. We'll see you next time.
Excellent video Sir. The other thing I see with friends who have installed them is improper routing of their refrigerant tube run which creates an oil trap as they do not know. That will cause a premature failure. I am called after the fact
Yeah auto is best. Except… One of the ones I put in my son's house doesn't throw the heat through the whole kitchen/dining room unless I set the fan on fast. It still cycles, only goes fast when actually heating. On auto it has a tendency to be satisfied when just the area in the immediate vicinity of the unit is up to setpoint. Then it short-cycles. Probably would be wiser to use an aux fan for wall mount motor longevity. But this is way easier. π
These high wall mounts are great for cooling, but for heating it's better to introduce the hot air at floor level.
i am sorry, but fan speed has NO bearing on output. yes, higher fan settings ALLOW more heat to be transfferd but its not the reason it uses more power. it will still want to hold the setpoint because that is the only thing it cares about and higher fan speeds allow the system to get to it faster. but once its there the power reduces even if the fan stays high. just advising blindly to set it auto is not good advice. setting it to forced low speeds also helps comfort and take away big temperature swings even if it reduces power output. the best advice is the one is the one you have not given: its to KEEP the system on so the room gets to temp and stays there. holding a temp is MUCH more efficient than turning it off and on constantly. Are you in Barrhaven ?
Have you made a video about how to do a heat load calculation? Or is that beyond the capabilities of a home owner? Service area Orleans??
Too many folks in society do not read instruction, period. I know people who have spent $75,000 on a brand new vehicle and simply refuse to read the owners manual. I have to laugh at those who won't because the will never know the capabilities and functions of their new vehicle vs. what they think they knew about their previous vehicle. Same goes with most of everything else. They'll purchase something from Home Depot or an appliance of some kind and never bother to read the instructions or the manual. Then, when something isn't going just right, they will screw with it, possibly damaging it way before referencing the book. Some people are just well off in buying the low end model if they will not read about the functions, features of their new purchases. It's amazing to observe those who paint themselves into a corner only because they never bothered to read and learn to operate the things they acquire. Reminds me of several politicians pushing their ideas before looking into the value in the matter.
I added an 8000 btu window unit to my master bedroom because my home units canβt keep up in the summer. I have a 3500 sq ft home with 7 tons of cooling.
A closet would eat up 1000 btu.

I have daikin aroura 36k BTU 2 units outside and six indoor units. Now in winter time I use for heat my main source. I been running in in heat mode and fan on auto. Should I use auto mode for temp also
The Mr Cool has the"dry" setting which I have used before in the room closest to the shower room, and in the dinning room when cooking a lot . Not sure if every brand has this option . In this setting it doesn't take long to pull the moisture out of the air . Thanks for the great help and videos .
Great advice.
