Unless the installer was ripping you off those were not comparable units. I've seen the manufacturer MSRP sheets and the cost difference between heat pump and non-heat pump for the same unit is small. Nowhere near enough to account for $11k. It sounds like they quoted you a bottom of the range 11 SEER A/C vs a top of the line multi-stage compressor variable speed blower 19 SEER heat pump system. Those are not the same thing.
