How many square feet does the Friedrich KHVM24B34A cool?

At 22,900 BTU/h it suits a room of about 1000 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 1100-1650 sq ft; in a very sunny one it shrinks to 900-1350 sq ft. A kitchen needs 4,000 BTU more.

How many watts and amps does the Friedrich KHVM24B34A use?

About 1817 watts at full power (22,900 BTU/h divided by its CEER of 12.6), which is 7.9 amps at 230 V. That is 73 W less than the typical unit in its class (1890 W), or $10 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 6% of the 17 units in the class.

What outlet does the Friedrich KHVM24B34A need?

It is a 230 V unit that draws 7.9 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 KHVM24B34A, and will it fit my window?

25.9" W × 17.9" H × 29" D, 135 lb. It is narrower than 56% of its 16 competitors and lighter than 38% of them. The window must be wider than 25.9"; the side panels fill the remaining gap.

How does the Friedrich KHVM24B34A 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 KHVM24B34A worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $344 a year to run at 750 hours and 18.0¢/kWh; this one costs about $246, so it saves roughly $98 a year.
