Compared with the other ENERGY STAR certified 10,000 BTU window units. Yearly cost at 750 hours and 18.0¢/kWh.

How many square feet does the Kühl+ KHVS10B11B cool?

At 10,600 BTU/h it suits a room of about 400 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 440-495 sq ft; in a very sunny one it shrinks to 360-405 sq ft. A kitchen needs 4,000 BTU more.

How many watts and amps does the Kühl+ KHVS10B11B use?

About 707 watts at full power (10,600 BTU/h divided by its CEER of 15.0), which is 6.1 amps at 115 V. That is 40 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 14% of the 28 units in the class.

Can the Kühl+ KHVS10B11B 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 Kühl+ KHVS10B11B, and will it fit my window?

25.9" W × 15.9" H × 29" D, 105 lb. It is narrower than 11% of its 27 competitors and lighter than 19% 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+ KHVS10B11B 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 105 lb, support it from outside until the bracket is fixed.

How does the Kühl+ KHVS10B11B heat?

It reverses its refrigerant cycle to work as a heat pump, which makes it one of only 6 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+ KHVS10B11B worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $159 a year to run at 750 hours and 18.0¢/kWh; this one costs about $96, so it saves roughly $64 a year.
