We need to buy a new central air and furnace for our home which is about 2200sf. We live in San Diego, CA, so the systems are 80 efficient. The two system we are looking into is the Maytag M1010 80 single stage furnace and Maytag M1010 16 Seer conditioner (with a 10 year labor 10 year labor) verses a Armstrong Air Ultra v80 furnace 5 ton air handler w/ heat pump and a 5 ton 13 seer condessing unit 213LE (with a 5 year limited warranty on parts for furnace, and 10-year limited warranty on compressor and 5-year on parts).
The Armstrong is about #250 more. So what do you think? Some advice would be great to direct us on a good choice for our home.
