I live in Philly. And need a new Gas furnace. My current one is 20yrs old and running around 70% eff. I have gotten 2 quotes.
Which is better:
Bryant #350 MAV, 92% BTUH with limited lifetime warranty on the heat exchanger, 3 yr Micro Processor, 5 yrs limited on parts, labor 1 yr.
Carrier Infinity 96 2 Stage variable speed furnace, Lifetime warranty on the heat exchanger, 10 yrs parts and labor
Trane XL 90 5 year parts and labor
