Hey everyone. Our basement system just crapped out on us (System had a massive leak in indoor coil and compressor is shot). We had a contractor come in earlier to quote us on a new system. He said he would do a load calculation, but I think he did it in his head (not good). Current system is Trane 1.5 ton XR11 from 2003 (Sad it lived short life, sigh...). Basement is around 2200 sq. ft. finished. l will definitely update this thread tomorrow as another contractor is coming out. Here's the estimates from today's contractor:
Remove old equipment and install new Trane XR13 1.5 ton R-410A heat pump with matching TAM4 2 ton air handler w/ 5 kw electric heat strips. Refrigerant lines will flushed and evacuated. New unit pad. New Secondary Drain pan for air handler.
This guy didn't recommend anything higher than 13 seer for our basement since a basement's heating/cooling load is very small (I've always known about small heating/air loads for basement). He also didn't really inspect the ductwork. He mentioned that the current supply and return plenums are okay. When he was going over the information about the new system with me, he said "The aluminum coil in the Trane Hyperion air handlers will never leak." Is this true??? (I think not)
So what's everyone's opinion on this estimate? Should I look elsewhere? I'll post the next estimate as soon as possible tomorrow. Any insight appreciated. Thanks in advance.
