Getting more quotes, part of the problem is because it is all located in the second story attic. (compressors outside) Getting rid of the 75 gallon water heater will not be fun but it will fit through the door and stairs. Looked at a heat pump, but would have to run more wiring. The panel has room and the double wall ovens are leaving, so another 220 breaker available. 200 AMP service. The two companies that have seen the setup both have said my duct work is good as is. From what little I can find on pricing on the web, $35K is too high. $20K would be more reasonable, and that would be for a higher end (SEER) system. Problem could be I had my truck with CA plates on it when one of the companies were there....... Replacing the windows as well, too many with broken seals. 27 windows and a slider $17K, which I thought was actually a good deal compared to Andersen or Pella pricing. Local company from Hot Springs, Window Mart.
