How many square feet does the Friedrich KCVL28B30A cool?

At 28,900 BTU/h it suits a room of about 1500 to 2000 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 1650-2200 sq ft; in a very sunny one it shrinks to 1350-1800 sq ft. A kitchen needs 4,000 BTU more.

How many watts and amps does the Friedrich KCVL28B30A use?

About 2189 watts at full power (28,900 BTU/h divided by its CEER of 13.2), which is 9.5 amps at 230 V. That is 299 W more than the typical unit in its class (1890 W), or $41 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 41% of the 17 units in the class.

What outlet does the Friedrich KCVL28B30A need?

It is a 230 V unit that draws 9.5 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 KCVL28B30A, and will it fit my window?

28" W × 20.2" H × 35.5" D, 155 lb. It is narrower than 6% of its 16 competitors and lighter than 13% of them. The window must be wider than 28"; the side panels fill the remaining gap.

Can the Friedrich KCVL28B30A also heat the room?

No, it only cools. If you also need heat, 3 certified units in this class can do both; see the list of air conditioners with heat.

Is the Friedrich KCVL28B30A worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $434 a year to run at 750 hours and 18.0¢/kWh; this one costs about $296, so it saves roughly $138 a year.

A good fit if…

You want the very top tier - it meets the ENERGY STAR Most Efficient criteria.

Think twice if…

You only have ordinary outlets - it needs a 230 V circuit and plug.
You plan to install it alone - at 155 lb it is a two-person job.
You also need heat - it cools only.
