Model
Friedrich WCVT10B10A
Rank #295 means 294 of the 404 room air conditioner models we track cost less to run each year; the 8th efficiency percentile means it uses less energy for its size than 8% of those models.
What does the Friedrich WCVT10B10A cost to run per year?
The Friedrich WCVT10B10A is a relatively costly runner for its class: about $118 a year, rank #295 of 404. It uses 37% less energy than the U.S. federal standard model in its class, which would cost about $187/yr to run, a saving of roughly $69 a year. Once capacity is factored in, its efficiency percentile of 8 is among the lowest in its class. Its CEER of 13 reflects combined energy efficiency ratio, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Friedrich KCVS12B30A at $118/yr runs a little cheaper and the Wallmaster WCVT12B30B at $118/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 WCVT10B10A's $118/yr adds up to roughly $1180 in electricity alone, before purchase price or repairs.
By the numbers
The Friedrich WCVT10B10A 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 $118/yr, here is what the Friedrich WCVT10B10A 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 WCVT10B10A costs about $1180. That is roughly $690 less than a standard model in its class, which would run closer to $1870 over the same ten years.
How the Friedrich WCVT10B10A compares
The room air conditioner class we track runs from $51 to $389 a year. At $118/yr, it runs about $19 a year above the class median of $99, and it is about $67 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $187/yr, the Friedrich WCVT10B10A uses 37% less energy.
What drives its running cost
At 11000 BTU/hr, the Friedrich WCVT10B10A is a mid-size room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. Its CEER of 13, below 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 Friedrich WCVT10B10A cheap to run?
Not especially. At $118 a year it ranks #295 of 404 room air conditioner models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Friedrich WCVT10B10A cost per month?
Roughly $9.82/mo, spreading the $118/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 635 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $118 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Friedrich WCVT10B10A for its size?
8th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
