      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 through-the-wall air conditioners.
      • You plan to install it alone - at 90 lb it is a two-person job.
      • You also need heat - it cools only.
      • You want to mount it in a window - it needs a wall sleeve.

      Questions6
      How many square feet does the Friedrich WCVT10B10A cool?
      At 11,000 BTU/h it suits a room of about 400 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 440-495 sq ft; in a very sunny one it shrinks to 360-405 sq ft. A kitchen needs 4,000 BTU more.
      How many watts and amps does the Friedrich WCVT10B10A use?
      About 846 watts at full power (11,000 BTU/h divided by its CEER of 13.0), which is 7.4 amps at 115 V. That is 17 W less than the typical unit in its class (863 W), or $2 a year cheaper to run at 18.0¢/kWh. Its inverter compressor slows down instead of cycling, so real use is usually lower. Its CEER beats 20% of the 15 units in the class.
      Can the Friedrich WCVT10B10A run on a standard outlet?
      Yes. It runs on 115 V and draws about 7.4 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. 60% 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 WCVT10B10A, and will it fit my window?
      26.5" W × 15.2" H × 21" D, 90 lb. It is narrower than 0% of its 14 competitors and lighter than 50% of them. It slides into a wall sleeve, so compare the sleeve opening with the unit before buying.
      Can the Friedrich WCVT10B10A also heat the room?
      No, it only cools. If you also need heat, 2 certified units in this class can do both; see the list of air conditioners with heat.
      Is the Friedrich WCVT10B10A worth buying to replace an old air conditioner?
      An old unit of the same size at 9 CEER would cost about $165 a year to run at 750 hours and 18.0¢/kWh; this one costs about $114, so it saves roughly $51 a year.

      Electricity used: 1,117 kWh a yearAn old 9 CEER unit of the same size would cost $258

      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).
