Compared with the other ENERGY STAR certified 12,000 BTU window units. Yearly cost at 750 hours and 18.0¢/kWh.

How many square feet does the Kühl+ KHVS12B33B cool?

At 12,600 BTU/h it suits a room of about 450 to 550 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 495-605 sq ft; in a very sunny one it shrinks to 405-495 sq ft. A kitchen needs 4,000 BTU more.

How many watts and amps does the Kühl+ KHVS12B33B use?

About 797 watts at full power (12,600 BTU/h divided by its CEER of 15.8), which is 3.5 amps at 230 V. That is 3 W less than the typical unit in its class (800 W), or $0 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 68% of the 34 units in the class.

What outlet does the Kühl+ KHVS12B33B need?

It is a 230 V unit that draws 3.5 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 12% of the 34 certified units in this class are 230 V.

What are the dimensions of the Kühl+ KHVS12B33B, and will it fit my window?

25.9" W × 15.9" H × 29" D, 115 lb. It is narrower than 3% of its 33 competitors and lighter than 0% 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 Kühl+ KHVS12B33B 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 115 lb, support it from outside until the bracket is fixed.

How does the Kühl+ KHVS12B33B heat?

It reverses its refrigerant cycle to work as a heat pump, which makes it one of only 5 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 Kühl+ KHVS12B33B worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $189 a year to run at 750 hours and 18.0¢/kWh; this one costs about $108, so it saves roughly $82 a year.
