Model
Friedrich KHVS10B11A
Rank #206 means 205 of the 404 room air conditioner models we track cost less to run each year; the 49th efficiency percentile means it uses less energy for its size than 49% of those models.
What does the Friedrich KHVS10B11A cost to run per year?
At about $101 a year, the Friedrich KHVS10B11A lands in the middle third of room air conditioner models we track on running cost, rank #206 of 404. It uses 43% less energy than the U.S. federal standard model in its class, which would cost about $178/yr to run, a saving of roughly $77 a year. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 49% of the models we track. At a CEER of 14, its combined energy efficiency ratio is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Seasons ST10VB2 at $99/yr runs a little cheaper and the Midea MAW12V1WBK at $104/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 KHVS10B11A's $101/yr adds up to roughly $1010 in electricity alone, before purchase price or repairs.
By the numbers
The Friedrich KHVS10B11A 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 $101/yr, here is what the Friedrich KHVS10B11A 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 KHVS10B11A costs about $1010. That is roughly $770 less than a standard model in its class, which would run closer to $1780 over the same ten years.
How the Friedrich KHVS10B11A compares
The room air conditioner class we track runs from $51 to $389 a year. At $101/yr, it runs about $2 a year above the class median of $99, and it is about $50 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $178/yr, the Friedrich KHVS10B11A uses 43% less energy.
What drives its running cost
At 10200 BTU/hr, the Friedrich KHVS10B11A 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. The CEER of 14 on this model, below 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). Two units with the same BTU rating can post very different running costs, and CEER is the figure that explains most of that gap.
- BTU cooling capacity. BTU rating scales with room size, and it is usually the first driver of an air conditioner's running cost, ahead of its CEER figure.
- Thermostat and mode usage. How the unit is actually operated, thermostat cycling versus a fixed setting, moves real electricity use more than the rated BTU or CEER figure alone.
Common questions
Is the Friedrich KHVS10B11A cheap to run?
Roughly, yes. Its $101/yr figure is close to the class median, ranking #206 of 404, neither a bargain nor a splurge on running cost.
How much does the Friedrich KHVS10B11A cost per month?
About $8.45 a month, which is the $101 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 546 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $101 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Friedrich KHVS10B11A for its size?
49th percentile once size is factored in, a fairly typical result for the class.
