AHC replaced my propane furnace with a Mitsubishi Heat Pump and Air Handler. They got me off propane, when it was $4.70 per unit! Do the math on a 224 gal tank $$$$ The first night of operation, we couldn't hear the unit running because it was so quiet. We were noticeably comfortable, with no cold spots in the house. P.S. They also did the installs at where I work!
