Model
K�Hl KCVS12B10B
Rank #218 means 217 of the 404 room air conditioner models we track cost less to run each year; the 46th efficiency percentile means it uses less energy for its size than 46% of those models.
What does the K�Hl KCVS12B10B cost to run per year?
The K�Hl KCVS12B10B costs about $106 a year to run, a middle-of-the-pack figure at rank #218 of 404. It uses 49% less energy than the U.S. federal standard model in its class, which would cost about $207/yr to run, a saving of roughly $101 a year. Its 46th size-adjusted efficiency percentile is unremarkable, close to what a typical model in the class scores. The CEER figure of 16.2 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 K�Hl KCVS12B30B at $105/yr runs a little cheaper and the Gree GJC12BU-A6DRNJ2A at $109/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 KCVS12B10B's $106/yr adds up to roughly $1060 in electricity alone, before purchase price or repairs.
By the numbers
The K�Hl KCVS12B10B 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 $106/yr, here is what the K�Hl KCVS12B10B 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 KCVS12B10B costs about $1060. That is roughly $1010 less than a standard model in its class, which would run closer to $2070 over the same ten years.
How the K�Hl KCVS12B10B compares
The room air conditioner class we track runs from $51 to $389 a year. At $106/yr, it runs about $7 a year above the class median of $99, and it is about $55 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $207/yr, the K�Hl KCVS12B10B uses 49% less energy.
What drives its running cost
At 12300 BTU/hr, the K�Hl KCVS12B10B is a large room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up. Its CEER of 16.2, 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 KCVS12B10B cheap to run?
It is about average. At $106 a year it ranks #218 of 404 room air conditioner models we track, close to the middle of its class on running cost.
How much does the K�Hl KCVS12B10B cost per month?
Roughly $8.81/mo, spreading the $106/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 569 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $106 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the K�Hl KCVS12B10B for its size?
46th percentile once size is factored in, a fairly typical result for the class.
