Hey guys before we get to the video, please click that subscribe button. Thank you, hey guys, joshua griffin here and i am out today fixing some heat for a few folks and, as you can see, it's a little rainy, little wintry little bit of snow out here, which is uh. You know not uncommon in virginia, but we're down near the water and we don't get a lot of snow so anyway, i wanted to do a video i've gotten a question uh twice actually in the past month, where folks are basically asking about replacing their line, sets They're they're having their systems replaced and they want to know. Is it a good idea to replace their line sets and i'm going to kind of go through that? I'm i i've got a few thoughts on the subject, but ultimately, what i'm talking about during the making of this video you know, there's all kinds of technologies coming out.

There will probably be more technologies coming out different materials, uh being made for the uh. You know line sets themselves and i'm just talking about you know old school copper line sets been using them for years, and you know we're still using them every day at griffin, air uh, we you know we'll we'll stretch new line, sets and raise them in with The new systems, now, if you have a uh, a package unit, you know you don't have uh line, sets running between an indoor and outdoor unit, they're all right there inside of the unit. So i'm talking about split systems where you have an outdoor unit, whether it be a heat pump or air conditioner, and you have an indoor unit, whether it's an air handler or furnace and so to get started on this subject. You know again, i want to go through a few things for you to think about and to get started.

I just want to say that in general, if it's not a big deal to replace the line, sets, i would say in general it's a good idea to replace them. You know you'll know it's peace of mind. You'll know they're new they've been brazen with the new system hypothetically, they should have no leaks. That said, uh, i don't think you know when people ask that question they're looking for a general, yes or no and i'm sure, there's heating and air, guys that'll watch this video and give their two cents.

Probably i i seem to get some of that and you know just folks saying: well we replace the lancets every time you know or this or that, but the reason i tread lightly on that is every house is different. You know uh, i don't think, there's a a blanket statement that you can say every time you should or you don't have to replace them, there's different scenarios. Moving on. I just want to say that in general, yes, it's a good idea to replace them, but in some cases you you know, i don't want to say you can't, but it would be a big chore to to replace them right.

So if the system is located in say, the crawl space or somewhere in your home might not be a big deal just stretch. New line sets pull the old ones out and you know you, you got new line sets, but if you have a system that is either in the attic or on the second floor of the home, but you know it's got to go down and out to the Outdoor unit, sometimes you're talking about opening up walls, you're talking about quite a project to get those line sets replaced - and i would here here in virginia - it's not unheard of for the systems to be in the attic for the air handler or the furnace to be. In the attic, i think the further you go south, the more that's true. You still can in a lot of cases, replace the line sets uh.

You may have to run them on the exterior of the home. If you don't want to open up walls and stuff, and then we encapsulate that in what we call slim duct or there's other brand names, but it's basically a vinyl tube of some type. It kind of looks like downspouts from your gutters running down the side of the house, but they're it's made of vinyl, and so you know it's not that big a deal if you know, if that's possible or you're. Okay with that, but let's just say you, you know you don't want that, you you're, you know it's not not in the cards.

Let me say this: there is no difference between the line sets that we installed 20 years ago with r22 systems, and the line sets that we have today, there's they're the same thickness best i can tell uh. You know the pressures went up when we went to 410a and you can hypothetically reuse the line sets now if you do reuse the line sets. Obviously you want to pressure test them in some cases flush them. It depends on your manufacturer.

Some manufacturers say they do want you to flush them. Some manufacturers say we don't want you flushing them. I would just follow whatever they say. They have the reasons for saying one way or the other in general.

For the longest time we would always flush them and then you know clean them out blow them out all that good stuff and then obviously pressure test and pull a good vacuum. But you know there are some manufacturers, they don't want. You know other contaminants coming into those landsats, for whatever reason that said, if you are going to reuse your landsats, if you follow you know, protocols follow the manufacturer's instructions and you know make those line sets as new as you can again. It's not the end of the world if you reuse the line sets in my opinion again, i know there's going to be people with other opinions, but it's not the end of the world.

You just want to make sure you cross your t's and dot your eyes. If you're not going to replace them, the last thing i want to just throw in there is just be aware that in some cases the line sets required for the new system may be a different size. So you know years ago, there's one particular brand that i can think of that you know they were okay. In fact, they you know put in their specs to run quarter inch liquid line sets these days in a lot of cases.

They're, not you know, newer systems they're, not okay, with that they want at least three eighths. Just in summary, you know, i would just say if you can replace them, it's probably a good idea to go ahead and replace them. But if you can't, in my opinion, it's not the end of the world, we reuse landsats, often it's not the end of the world. You just want to make sure you're doing what you're supposed to do as far as the contractor goes taking them off the old unit.

Raising them into the new unit is not.
