1. I don't like the idea of calling Goodman every time I have warranty work to get reimbursed.
2. I think the whole process is deceptive and unethical. Probably most of the blame lies on Goodman for allowing the loophole, but the contractor is not completely innocent either.
Agree the install was done very well and in general the original contractor has done a pretty good job in the past. I have two units (the other one is Carrier and is out of warranty). Same contractor installed both units. Earlier this year a leak developed in one of the capillary tubes on the Carrier. The original contractor said the whole condenser had to be replaced at a very high cost. I called another contractor for a 2nd opinion. The 2nd contractor agreed to repair the capillary at overall less than half the cost of replacing the condenser. (the biggest cost was 8.5 lbs of R22....ouch!!!)
Reason I mention this is I'm not 100% happy with original contractor based on these two incidents. However, I agree the risk is great moving to another contractor who did not install the system. It's a matter of holding on principal vs. taking the path of least resistance (I tend NOT to be a guy who takes path of least resistance!!)
