I'm attempting to heat and cool the second floor of an old house with no current heating or cooling. I've had 4 contractors look at the job all selling differnt brands of equipment. The general consensus is that a 2 or 2.5 ton air source heat pump with the air handler with a 5 or 10 kw heat strip and duct work in the attic.
The bids vary widely in price. I've asked all to bid their recommendations although I made it a point to let them know I try to be a value buyer (want equipment of quality and efficiency that will pay off in the long run). From my reading on this site, it seems the more important factor in value is finding a contractor that does a quality installation job. My problem is I am ignorant on what to look for in a good contractor. Can somebody give me a few questions I should ask?
Thanks for any suggestion.
P.S. Should I rule out the contractor that didn't bring a tape measure? I did tell him approximately how many square feet. Would you be surprised if I told you he was the cheapest by almost 25% over the next lowest?
