Hi, I plan changing my furnace. I have a 20 year old trane 40,000 BTU. I live in a condo, Approximate lot is 2516SF. 2 bathrooms, 2 bedrooms, kitchen, living room, dining room. My gas bill on the average is $130 in the winter per month in Jersey at average 74F. I assume the old one is Single Stage, works well, but I have to change the evaporator coil, so it would cost me less, to change both furnace and evaporator coil. I have 3 guys come out, and listen to what they want to propose. I plan getting an 80% AFUE, all recommend 80,000 BTU, that has 64000 BTU output, dont quite get, why all say I need 80000BTU, only one person said I need 60000BTU. Now I have to choose, single vs 2 stage furnace? I know lot of people told me its great in a house, the furnace runs longer at lower speeds etc. But I live in a condo, the difference between rooms is at max 3F which is the living/dining room since its big, compare to the other rooms, so if its 74 everywhere, the living room is 71F.
