      A good fit if…

      • You want heat in spring and fall - it runs as a heat pump in reverse.
      • You want to plug it into an ordinary outlet - it runs on 115 V.

      Think twice if…

      • Running cost matters most - its CEER is below average for 10,000 BTU window air conditioners.
      • You plan to install it alone - at 105 lb it is a two-person job.

      Questions6
      How many square feet does the Friedrich KHVS10B11A cool?
      At 10,200 BTU/h it suits a room of about 350 to 450 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 385-495 sq ft; in a very sunny one it shrinks to 315-405 sq ft. A kitchen needs 4,000 BTU more.
      How many watts and amps does the Friedrich KHVS10B11A use?
      About 729 watts at full power (10,200 BTU/h divided by its CEER of 14.0), which is 6.3 amps at 115 V. That is 62 W more than the typical unit in its class (667 W), or $8 a year dearer to run at 18.0¢/kWh. Its inverter compressor slows down instead of cycling, so real use is usually lower. Its CEER beats 0% of the 28 units in the class.
      Can the Friedrich KHVS10B11A run on a standard outlet?
      Yes. It runs on 115 V and draws about 6.3 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. Every certified unit in this class is 115 V.
      What are the dimensions of the Friedrich KHVS10B11A, and will it fit my window?
      25.9" W × 15.9" H × 29" D, 105 lb. It is narrower than 11% of its 27 competitors and lighter than 19% of them. The window must be wider than 25.9"; the side panels fill the remaining gap.
      How does the Friedrich KHVS10B11A heat?
      It reverses its refrigerant cycle to work as a heat pump, which makes it one of only 6 certified units in its class that heat. Heating output is not part of the ENERGY STAR data, so ask the maker for its heating capacity and lowest outdoor temperature before relying on it in winter.
      Is the Friedrich KHVS10B11A worth buying to replace an old air conditioner?
      An old unit of the same size at 9 CEER would cost about $153 a year to run at 750 hours and 18.0¢/kWh; this one costs about $99, so it saves roughly $55 a year.

      Electricity used: 962 kWh a yearAn old 9 CEER unit of the same size would cost $239

      Power draw is capacity divided by CEER, which already includes standby power. Inverter units often run below full power, so real use can be lower. Electricity prices: U.S. EIA residential averages (12 months to July 2026). Days a year start from your state's cooling degree days (NOAA 1991-2020 normals).
