Hello everyone, I have 1 yr of residential hvac expirence (9 months service, 3 months install). I want to replace my 13 year old heatpump. I'm at a point where I want to do it myself just to make sure it's done right, but there's still a ton I don't know, mainly on the job planning side. So, I'm looking for help on picking a manufacturer. I think in my research so far, I've found that brand truly doesnt matter, its all about install quality and technician support when you do have a problem. So, I'm curious if anyone here has some good insight on manufacturers who are easy to work with if I only have my EPA. Mainly looking for widely available/inexpensive parts. I'm thinking Rheem/Ruud because both companies I've worked for sold them, but I'm curious about goodman, too. Thanks! Edit: will they or anyone even allow me to register for a warranty if I installed it myself?

I’m comfortable working on R22 and 410a systems. Are there any videos about DIY installing the new R32 and 454b systems?

Anybody have any experience with EliTech -LMG 10-W or 10Plus gauges? Worth getting? Thxs

Hello, I am hoping someone can help with a problem I am having evacuating a new ACIQ heat pump. I have performed a Nitrogen pressure test at 290 psi with zero psi drop after 30 minutes. No leaks found. However for the vacuum test I can only pull down to approx 700 microns and when I isolate the system it raises to approx 1700 and holds there. Using CPS micron gauge with Schrader core removed on low side. I have tested my entire vacuum system by placing a shut off valve on the end of the core removal tool that connects to the ac port and can easily pull down to 300 microns and hold there when I isolate from the vacuum pump. I am at wits end trying to figure why I cannot pull down below 500 microns and stay close to that value once isolated from the pump. Not comfortable releasing the Freon with this high micron level. Any suggestions? Thank you.

I’ll be replacing my 3.5 ton Goodman soon. How do you determine if the lines need to be replaced? I’m on a concrete slab, so not sure how they are run.
