Model
Friedrich KCVS08B10A
Rank #114 means 113 of the 404 room air conditioner models we track cost less to run each year; the 71st efficiency percentile means it uses less energy for its size than 71% of those models.
What does the Friedrich KCVS08B10A cost to run per year?
At $76 a year to run, the Friedrich KCVS08B10A runs cheaper than most models in its class, ranking #114 of 404 room air conditioner models we track. It uses 47% less energy than the U.S. federal standard model in its class, which would cost about $143/yr to run, a saving of roughly $67 a year. Once capacity is factored in, its 71th efficiency percentile puts it ahead of most peers in its class. The CEER figure of 16 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 Midea MWCUPWHP-09HEFN8-BCL1N at $75/yr runs a little cheaper and the Keystone KSTAW08INV-HC at $77/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 Friedrich KCVS08B10A's $76/yr adds up to roughly $760 in electricity alone, before purchase price or repairs.
By the numbers
The Friedrich KCVS08B10A 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 $76/yr, here is what the Friedrich KCVS08B10A adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Friedrich KCVS08B10A costs about $760. That is roughly $670 less than a standard model in its class, which would run closer to $1430 over the same ten years.
How the Friedrich KCVS08B10A compares
The room air conditioner class we track runs from $51 to $389 a year. At $76/yr, it runs about $23 a year cheaper than the class median of $99, and it is about $25 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $143/yr, the Friedrich KCVS08B10A uses 47% less energy.
What drives its running cost
At 8700 BTU/hr, the Friedrich KCVS08B10A is a small room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, and smaller room air conditioner models generally cost less to run for the same job, all else being equal. The CEER of 16 on this model, above the class median of 15, measures combined energy efficiency ratio; it is the number to compare directly against another model's CEER if capacity is similar.
- 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 Friedrich KCVS08B10A cheap to run?
Yes, relatively. At $76 a year it ranks #114 of 404 room air conditioner models we track, in the cheaper part of its class to run.
How much does the Friedrich KCVS08B10A cost per month?
Roughly $6.31/mo, spreading the $76/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 408 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $76 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Friedrich KCVS08B10A for its size?
71st percentile once size is factored in, a fairly typical result for the class.
