Model
Friedrich KHVM24B34A
Rank #393 means 392 of the 404 room air conditioner models we track cost less to run each year; the 2nd efficiency percentile means it uses less energy for its size than 2% of those models.
What does the Friedrich KHVM24B34A cost to run per year?
The Friedrich KHVM24B34A costs about $253 a year to run, near the very top of the cost table for its class at rank #393 of 404. It uses 35% less energy than the U.S. federal standard model in its class, which would cost about $389/yr to run, a saving of roughly $136 a year. Capacity-normalized, it ranks ahead of just 2% of room air conditioner models we track, near the bottom of every model we track in the class. Its CEER of 12.6 reflects combined energy efficiency ratio, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Sea Breeze WA324ZREB at $251/yr runs a little cheaper and the Friedrich CCV24A30A at $263/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 KHVM24B34A's $253/yr adds up to roughly $2530 in electricity alone, before purchase price or repairs.
By the numbers
The Friedrich KHVM24B34A 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 $253/yr, here is what the Friedrich KHVM24B34A 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 KHVM24B34A costs about $2530. That is roughly $1360 less than a standard model in its class, which would run closer to $3890 over the same ten years.
How the Friedrich KHVM24B34A compares
The room air conditioner class we track runs from $51 to $389 a year. At $253/yr, it runs about $154 a year above the class median of $99, and it is about $202 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $389/yr, the Friedrich KHVM24B34A uses 35% less energy.
What drives its running cost
At 22900 BTU/hr, the Friedrich KHVM24B34A is a large room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, and larger room air conditioner models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. Its CEER of 12.6, 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). 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 KHVM24B34A cheap to run?
Its $253/yr running cost, rank #393 of 404, is above what most room air conditioner models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Friedrich KHVM24B34A cost per month?
About $21.08 a month, which is the $253 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: 1,363 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $253 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Friedrich KHVM24B34A for its size?
2nd 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.
