Pre-Charged Line Sets Are For Real, Right?

pre-charged line sets

Pre-charged line sets aren’t exactly a new innovation in the HVAC industry, but they’re not exactly widespread either. When we tell people our MRCOOL DIY line sets do not need to be vacuumed down, plenty of installers out there, professional or otherwise, just don’t believe it. But, hey, don’t take my word for it!

Pre-Charged Line Sets Are the Real Deal

A picture is worth a thousand words, so a YouTube video has to be worth like a novel or something. Anyway, check out the comments in our 2nd-generation DIY install video and you’ll find plenty of folks who don’t quite believe. If you don’t want to take the time, then I’ll sum up the highlights for you.

No vacuum? Are you kidding me?” – St2288

How is that possible?” – E Money

Don’t you have to use a vacuum pump or purge the lines?” – Juan Silva

Wait a sec, no purge of the line-set or vacuuming them down first?” – Butchtropic

Yeah, there are a few skeptics.

So, Are Pre-Charged Line Sets Real or What?

Yes! For the last time, yes!

We here at MRCOOL did not invent pre-charged line sets. They’ve been around for years, but were mainly confined to the modular and mobile home market. That might be one reason why so many people have not heard of them. Don’t worry! Pre-charged line set technology proved itself years ago.  Basically, all we’re doing is applying them in an innovative way.

Innovative How?

One or two manufacturers have used a version of pre-charged line sets on ductless mini-split units before, but we are proud to say that no one has taken it as far as we have. The MRCOOL DIY 2nd-generation Ductless Mini-Split Heat Pump is truly cutting edge technology. Our unique approach makes line sets easy and safe to handle. Best of all, any smart homeowner can put one of our DIY units up in a few hours with no specialized tools.

It’s like they’re comfort made simple or something.
