I had 2 companies quote A/C installation but I can't find enough information to compare the quotes. One contractor gave me quotes for different comparable units (Comfortmaker N4A348 & C4A348, Carrier 24ACB48 & 24APA548), which appear to be 4 ton units from what I find online. He quoted a price for each and specified the SEER and warranty differences. From other threads I've seen on this forum it appears that there isn't much reason to choose Carrier over Comfortmaker for comparable models. Are these models truly comparable?
A second company quoted a Carrier 24ACB436A003, which appears to be a 3 ton unit, but this was actually the more expensive quote. Is this unit better than the ones above for some other reason?
Thanks in advance for you help, Steve
