      A good fit if…

      • You want heat in spring and fall - it runs as a heat pump in reverse.

      Think twice if…

      • Running cost matters most - its CEER is below average for 24,000 BTU and up window air conditioners.
      • You only have ordinary outlets - it needs a 230 V circuit and plug.
      • You plan to install it alone - at 160 lb it is a two-person job.

      Questions6
      How many square feet does the Friedrich KHVL28B35A cool?
      At 28,200 BTU/h it suits a room of about 1400 to 1500 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 1540-1650 sq ft; in a very sunny one it shrinks to 1260-1350 sq ft. A kitchen needs 4,000 BTU more.
      How many watts and amps does the Friedrich KHVL28B35A use?
      About 2238 watts at full power (28,200 BTU/h divided by its CEER of 12.6), which is 9.7 amps at 230 V. That is 348 W more than the typical unit in its class (1890 W), or $47 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 6% of the 17 units in the class.
      What outlet does the Friedrich KHVL28B35A need?
      It is a 230 V unit that draws 9.7 A, so it needs its own 230 V circuit with a matching plug (typically NEMA 6-15 or 6-20). If the room has only ordinary 115 V outlets, an electrician has to add one. Only 100% of the 17 certified units in this class are 230 V.
      What are the dimensions of the Friedrich KHVL28B35A, and will it fit my window?
      28" W × 20.2" H × 35.5" D, 160 lb. It is narrower than 6% of its 16 competitors and lighter than 0% of them. The window must be wider than 28"; the side panels fill the remaining gap.
      How does the Friedrich KHVL28B35A heat?
      It reverses its refrigerant cycle to work as a heat pump, which makes it one of only 3 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 KHVL28B35A worth buying to replace an old air conditioner?
      An old unit of the same size at 9 CEER would cost about $424 a year to run at 750 hours and 18.0¢/kWh; this one costs about $303, so it saves roughly $121 a year.

      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).
