      A good fit if…

      • You want low bills - its CEER beats 97% of 14,000-15,000 BTU window air conditioners.
      • You want the window view kept - the unit hangs over the sill, with the bulk outside and below the window.
      • You want to plug it into an ordinary outlet - it runs on 115 V.
      • You want the very top tier - it meets the ENERGY STAR Most Efficient criteria.

      Think twice if…

      • You also need heat - it cools only.

      Questions7
      How many square feet does the Friedrich KCVM14B10B cool?
      At 14,100 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 KCVM14B10B use?
      About 870 watts at full power (14,100 BTU/h divided by its CEER of 16.2), which is 7.6 amps at 115 V. That is 67 W less than the typical unit in its class (938 W), or $9 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 93% of the 15 units in the class.
      Can the Friedrich KCVM14B10B run on a standard outlet?
      Yes. It runs on 115 V and draws about 7.6 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 KCVM14B10B, and will it fit my window?
      25.9" W × 17.9" H × 29" D, 70 lb. It is narrower than 14% of its 14 competitors and lighter than 71% of them. It hangs over the sill, so check the sill depth and that the window can open far enough to set the unit in.
      Is the Friedrich KCVM14B10B saddle design an advantage?
      For the view, yes: most of the body sits outside and below the sill, so it blocks less of the window than a box unit. At 70 lb, support it from outside until the bracket is fixed.
      Can the Friedrich KCVM14B10B 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 KCVM14B10B worth buying to replace an old air conditioner?
      An old unit of the same size at 9 CEER would cost about $212 a year to run at 750 hours and 18.0¢/kWh; this one costs about $118, so it saves roughly $94 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.
