We have gotten 3 bids and none to my knowledge have done a manual J or D. All have done a room by room analysis. The company he signed w/ was the lowest by a little and is our current service company. Do these sound ok?
Carrier Infinity 95% AFUE variable speed 110k BUT gas furnace #58MVC110-20
Carrier Infinity 21 SEER 2-spd puron 4 ton condensing unit #24ANA148A003
high effic. evaporator coil #C60A210C52
Carrier Infinity digital/programmable therm #SYSTXCCUID01 (not an IAQ, right? good enuf?)
Carrier EZ flex air filter media
We had originally talked about the 80% but today when he met w/ the guy, he went w/ the 95%. We currently have a Trane 80%. We have a basement, main floor & top floor - 2400 sq ft, 800 addt'l in basement (we have a heat n glo down there so no need for that area and stays cool in the summer).
Please advise if this looks correct/matching and what changes we should make.
Thanks very much.
