It sounds like a leak in the coil of the old system. They have proposed several new systems, the one I like is a Seer 16 2 stage compressor system, Merv 11 filter, bi polar ionization system, and a 9.0 HSPF rating whatever that is. All inclusive $9888 and they are "checking" to see if there are any coupons. The next one up is a SEER 18 system, 5 stage compressor for $13414.
Are these prices in line? Should I go for the higher system? I plan to be here for 10+ years.
Edit: 4 ton systems, 2200 sq ft
Edit 2: Just talked with my brother in law who runs a commercial heating and air business (not locally) he says that is too high and get some additional quotes so that is what I am doing...
