We jut purchased a 20-year old 3000' open home in the foothills - only 2 seperate rooms. We need to put in central heat and air. We are thinking of the Amana Air Command 95 IIq and Prestige 2. We were given a quote of $11,000.00 for the removal of the non-working heat pump, the installation of ducts and the units. Any thoughts and suggestions will be appreciated.
