Help starting quote process for furnace & AC
I have to get both a furnace and AC. Existing furnace was here when I bought the house in 1977. No existing AC. When they come to give me estimates, what questions should I ask? Also, I'm a Costco member and they have a furnace replacement program, should I get an estimate from them too or avoid that type of deal?
If it makes any difference, I have a 980sq ft ranch with an unfinished basement.
