How to check hvac refrigerant charge level on mini split DIY

okay everyone thank you once again for
tuning into our YouTube channel and the purpose of this video is if you have
installed a mini-split unit yourself or if you have bought one and it didn't
come with enough refrigerant or maybe while you were putting in the flared
copper lines on the inside and you had some refrigerant leak out of the system
just like you see in this case here it's starting to freeze up what you want to
do first is you want to make sure that your refrigerant levels are up to par
and what we're going to do is connect this blue hose with these gauges on to
the connector down below now a standard connector like this one will not work so
you need to buy an adapter and that's what we have here and I'll post a link
on how you can get these as well but first you want to tighten it you want to
use a little wrench make sure that it's nice and tight and then you want to go
ahead and put this down at the bottom so we can get a reading so we're going to
do that next okay so as you can see down here I've
already got my adapter in there and I made sure I tightened it well not only
here but here as well and what we're gonna do is you open your low side and
you can tell if you're doing this for the first time or you don't know how to
tell it's on your low side so some gauges will tell you low and high I mean
that's as simple as it gets but it's basically your blue hose you connect it
to the access port don't get confused with these two things here these are
just to open and close when you're releasing the refrigerant so if you look
in there after you take these out you'll see that you have a space for an Allen
wrench that's not for that for for what we're doing here this is the part and
you'll tell because if you were to remove this inside there's like a little
pin that looks like a tire gauge it's a straighter pal and that's why you're
going to connect your blue hose to so the sweet spot when you're measuring
your psi down here you want it to be around the 117 120 range and you can see
this is about half so obviously it needs refrigerant so that's how you can tell
if your unit is not cooling very well or if you see some freezing like if you see
some freezing up here icing up and on the coils on the inside of your unit
when you're running in cooling mode that's not a good sign so in this case
it obviously needs refrigerant so we're going to go ahead and add it and to do
that we're going to do another video and if you go ahead and click on the video
that will pop up on the screen it'll take you straight to that so you can see
how we add refrigerant to it
