      A good fit if…

      • 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 14,000-15,000 BTU window air conditioners.
      • You plan to install it alone - at 120 lb it is a two-person job.
      • You also need heat - it cools only.

      Questions6
      How many square feet does the Friedrich KCVM14B10A cool?
      At 13,900 BTU/h it suits a room of about 450 to 700 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 495-770 sq ft; in a very sunny one it shrinks to 405-630 sq ft. A kitchen needs 4,000 BTU more.
      How many watts and amps does the Friedrich KCVM14B10A use?
      About 946 watts at full power (13,900 BTU/h divided by its CEER of 14.7), which is 8.2 amps at 115 V. That is 9 W more than the typical unit in its class (938 W), or $1 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 27% of the 15 units in the class.
      Can the Friedrich KCVM14B10A run on a standard outlet?
      Yes. It runs on 115 V and draws about 8.2 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. 13% of certified units in this class need 230 V, so a 115 V model is the easy case.
      What are the dimensions of the Friedrich KCVM14B10A, and will it fit my window?
      25.9" W × 17.9" H × 29" D, 120 lb. It is narrower than 14% of its 14 competitors and lighter than 0% of them. The window must be wider than 25.9"; the side panels fill the remaining gap.
      Can the Friedrich KCVM14B10A also heat the room?
      No, it only cools. If you also need heat, 0 certified units in this class can do both; see the list of air conditioners with heat.
      Is the Friedrich KCVM14B10A worth buying to replace an old air conditioner?
      An old unit of the same size at 9 CEER would cost about $209 a year to run at 750 hours and 18.0¢/kWh; this one costs about $128, so it saves roughly $81 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).
