Model
K�Hl+ KHVS10B11B
Rank #197 means 196 of the 404 room air conditioner models we track cost less to run each year; the 51st efficiency percentile means it uses less energy for its size than 51% of those models.
What does the K�Hl+ KHVS10B11B cost to run per year?
Do the math and the K�Hl+ KHVS10B11B's $98/yr puts it at rank #197 of 404, right around the class average. It uses 53% less energy than the U.S. federal standard model in its class, which would cost about $209/yr to run, a saving of roughly $111 a year. Adjusted for size, it is more efficient than 51% of room air conditioner models we track, a middling result. The CEER figure of 15 on this model captures combined energy efficiency ratio, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Ge Profile PHNT10CCH1 at $98/yr runs a little cheaper and the Midea MAT10R1FWTK at $99/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A room air conditioner typically stays in service for somewhere around 10 years; over that span, the K�Hl+ KHVS10B11B's $98/yr adds up to roughly $980 in electricity alone, before purchase price or repairs.
By the numbers
The K�Hl+ KHVS10B11B normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $98/yr, here is what the K�Hl+ KHVS10B11B adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the K�Hl+ KHVS10B11B costs about $980. That is roughly $1110 less than a standard model in its class, which would run closer to $2090 over the same ten years.
How the K�Hl+ KHVS10B11B compares
The room air conditioner class we track runs from $51 to $389 a year. At $98/yr, it runs about $1 a year cheaper than the class median of $99, and it is about $47 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $209/yr, the K�Hl+ KHVS10B11B uses 53% less energy.
What drives its running cost
At 10600 BTU/hr, the K�Hl+ KHVS10B11B is a mid-size room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. Its CEER of 15, above the class median of 15, reflects combined energy efficiency ratio: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- Combined Energy Efficiency Ratio (CEER). CEER captures cooling output per watt, including standby power; a higher CEER means less electricity for the same BTU of cooling.
- BTU cooling capacity. A higher-BTU unit is sized for a bigger room and generally uses more electricity per hour of operation than a smaller unit, regardless of efficiency.
- Thermostat and mode usage. Running on a fixed low temperature around the clock uses far more energy than using a thermostat setting, eco mode, or a timer to match cooling to when the room is actually occupied.
Common questions
Is the K�Hl+ KHVS10B11B cheap to run?
It is about average. At $98 a year it ranks #197 of 404 room air conditioner models we track, close to the middle of its class on running cost.
How much does the K�Hl+ KHVS10B11B cost per month?
Roughly $8.2/mo, spreading the $98/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 530 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $98 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the K�Hl+ KHVS10B11B for its size?
51st percentile once size is factored in, a fairly typical result for the class.
