Model
Friedrich KCVM14B10A
Rank #335 means 334 of the 404 room air conditioner models we track cost less to run each year; the 19th efficiency percentile means it uses less energy for its size than 19% of those models.
What does the Friedrich KCVM14B10A cost to run per year?
Among the 404 room air conditioner models we track, the Friedrich KCVM14B10A's $132/yr running cost ranks it #335, in the pricier fifth of the class. It uses 35% less energy than the U.S. federal standard model in its class, which would cost about $202/yr to run, a saving of roughly $70 a year. Size-adjusted, this model ranks near the bottom of its class on efficiency, ahead of just 19% of room air conditioner models we track. The CEER figure of 14.7 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 Vissani VAWA14V4HWT at $130/yr runs a little cheaper and the Lg LW1522FVSM at $133/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 KCVM14B10A's $132/yr adds up to roughly $1320 in electricity alone, before purchase price or repairs.
By the numbers
The Friedrich KCVM14B10A 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 $132/yr, here is what the Friedrich KCVM14B10A 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 KCVM14B10A costs about $1320. That is roughly $700 less than a standard model in its class, which would run closer to $2020 over the same ten years.
How the Friedrich KCVM14B10A compares
The room air conditioner class we track runs from $51 to $389 a year. At $132/yr, it runs about $33 a year above the class median of $99, and it is about $81 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $202/yr, the Friedrich KCVM14B10A uses 35% less energy.
What drives its running cost
At 13900 BTU/hr, the Friedrich KCVM14B10A 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. Beyond size, its CEER of 14.7, below the class median of 15, is the class's own efficiency yardstick, combined energy efficiency ratio, and it is what separates two similarly sized models with different running costs.
- 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 KCVM14B10A cheap to run?
Its $132/yr running cost, rank #335 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 KCVM14B10A cost per month?
About $10.97 a month, which is the $132 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: 709 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $132 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Friedrich KCVM14B10A for its size?
19th 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.
