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?
