How many square feet does the Friedrich WCVT10B30B cool?

At 10,000 BTU/h it suits a room of about 350 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 385-495 sq ft; in a very sunny one it shrinks to 315-405 sq ft. A kitchen needs 4,000 BTU more.

How many watts and amps does the Friedrich WCVT10B30B use?

About 704 watts at full power (10,000 BTU/h divided by its CEER of 14.2), which is 6.1 amps at 115 V. That is 37 W more than the typical unit in its class (667 W), or $5 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 4% of the 28 units in the class.

Can the Friedrich WCVT10B30B run on a standard outlet?

Yes. It runs on 115 V and draws about 6.1 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. Every certified unit in this class is 115 V.

What are the dimensions of the Friedrich WCVT10B30B, and will it fit my window?

26.5" W × 15.8" H × 21" D, 110 lb. It is narrower than 0% of its 27 competitors and lighter than 15% of them. The window must be wider than 26.5"; the side panels fill the remaining gap.

Can the Friedrich WCVT10B30B also heat the room?

No, it only cools. If you also need heat, 6 certified units in this class can do both; see the list of air conditioners with heat.

Is the Friedrich WCVT10B30B worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $150 a year to run at 750 hours and 18.0¢/kWh; this one costs about $95, so it saves roughly $55 a year.
