How many square feet does the Whirlpool WHAW242INV cool?

At 24,000 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 Whirlpool WHAW242INV use?

About 1739 watts at full power (24,000 BTU/h divided by its CEER of 13.8), which is 7.6 amps at 230 V. That is 151 W less than the typical unit in its class (1890 W), or $20 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 59% of the 17 units in the class.

What outlet does the Whirlpool WHAW242INV need?

It is a 230 V unit that draws 7.6 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 Whirlpool WHAW242INV, and will it fit my window?

25.4" W × 16.9" H × 26.4" D, 101 lb. It is narrower than 75% of its 16 competitors and lighter than 81% of them. The window closes into the U-shaped slot, so measure the opening height as well as the width: you need at least the unit's 25.4" width between the frame sides.

Is the Whirlpool WHAW242INV U-shaped design an advantage?

Mostly yes. The sash closes into the unit, so the window stays sealed and daylight comes in, and the compressor is outside the glass, which cuts noise indoors. The trade-off is a window that must slide up and down, and a few extra steps to fit the foam seals.

Can the Whirlpool WHAW242INV 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 Whirlpool WHAW242INV worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $361 a year to run at 750 hours and 18.0¢/kWh; this one costs about $235, so it saves roughly $125 a year.

Is the Whirlpool WHAW242INV the same as the Whirlpool WHHW242INV?

As far as the certified data goes, yes. ENERGY STAR lists both model numbers with the same capacity, efficiency, energy use, dimensions and weight, which means the same unit sold under another brand or with a different colour or retailer code. The full list is on this page.
