I've received three quotes for a new furnace and heat pump system. My house (2100sq. ft.) has plenty of insulation for the region, new windows, new doors. two of the quotes include a 100,000 BTU (80%) furnace, and the third includes an 80,000 (80%) BTU furnace. The third is also the only one who ran any heat load calculations on the house. I grew up in a home without gas heat, so my knowledge of BTUs is lacking. Are 20,000 BTUs enough that I'm losing the efficiency of the furnace by having to large of a furnace for the house? To ask in another way, am I losing money if I choose a 100,000 btu furnace if an 80,000 btu furnace is enough? (other than the 100,000 furnace cost a little more upfront?)
Question #2: I think the load calc. stated my house needs 62,000 BTUs of heat, an (80%) 80,000 BTU furnace is going to provide 64,000. Is a 2,000 BTU cushion enough that I'm not going to have a cool home in a few years when the furnace begins to lose it's efficiency?
Thanks for the help.
