Model
Friedrich KCVL36B30A
Rank #404 means 403 of the 404 room air conditioner models we track cost less to run each year; the 0th efficiency percentile means it uses less energy for its size than 0% of those models.
What does the Friedrich KCVL36B30A cost to run per year?
Do the math and the Friedrich KCVL36B30A's $389/yr puts it at rank #404 of 404, in the bottom five percent on cost for its class. It uses 36% less energy than the U.S. federal standard model in its class, which would cost about $608/yr to run, a saving of roughly $219 a year. Adjusted for size, it is only more efficient than 0% of room air conditioner models we track, among the lowest size-adjusted results we track for the class. At a CEER of 12.2, its combined energy efficiency ratio is the single figure that best explains how it earns its running-cost number.
On the leaderboard, the K�Hl KCVL36B30B at $343/yr runs a little cheaper, the closest neighbor to its exact spot in the ranking. A room air conditioner typically stays in service for somewhere around 10 years; over that span, the Friedrich KCVL36B30A's $389/yr adds up to roughly $3890 in electricity alone, before purchase price or repairs. At rank #404 of 404, it sits at the very top of the cost range for its class, among the single priciest models we track to run.
By the numbers
The Friedrich KCVL36B30A 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 $389/yr, here is what the Friedrich KCVL36B30A 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 KCVL36B30A costs about $3890. That is roughly $2190 less than a standard model in its class, which would run closer to $6080 over the same ten years.
How the Friedrich KCVL36B30A compares
The room air conditioner class we track runs from $51 to $389 a year. At $389/yr, it runs about $290 a year above the class median of $99, and it is about $338 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $608/yr, the Friedrich KCVL36B30A uses 36% less energy.
What drives its running cost
At 34100 BTU/hr, the Friedrich KCVL36B30A 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 12.2, 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 KCVL36B30A cheap to run?
Not especially. At $389 a year it ranks #404 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 KCVL36B30A cost per month?
Roughly $32.42/mo, spreading the $389/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 2,096 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $389 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Friedrich KCVL36B30A for its size?
0th 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.
