Carrier 51QCA209101B 8500 BTU Window Heat Pump AC Unit 115V 60Hz R-22 EER 9.5

The Carrier 51QCA209101B is a window-mount combination heat pump and air conditioner rated at 8,500 BTU cooling and 7,500 BTU heating. This unit is being sold as-is: the cooling function is not operational and the unit requires an R-22 freon recharge before it will cool. The heating function has been confirmed to work. No mounting hardware is included.

Applications

Window-mount heat pump/AC combination units like the Carrier 51QCA209101B are designed to provide both cooling and electric resistance-free heating from a single window installation. The heat pump heating mode transfers heat from outdoor air into the room rather than generating it electrically, which is why the COP (coefficient of performance) exceeds 1.0 — it moves more energy than it consumes. Units in this class were commonly used in residential rooms, small offices, hotel rooms, and light commercial spaces where year-round climate control from a single window opening was needed. The R-22 refrigerant specification places this unit in the pre-2010 era, before R-22 was phased out under EPA regulations; R-22 is still available as a service refrigerant for recharging existing equipment, though its cost has risen significantly. This unit is suited for someone able to recharge the refrigerant and restore cooling capability, or for use as a heater only.
