Model
K�Hl KCVL36B30B
Rank #403 means 402 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 K�Hl KCVL36B30B cost to run per year?
The K�Hl KCVL36B30B costs about $343 a year to run, near the very top of the cost table for its class at rank #403 of 404. It uses 49% less energy than the U.S. federal standard model in its class, which would cost about $672/yr to run, a saving of roughly $329 a year. Efficiency-wise, once size is accounted for, almost the entire class outperforms it, at just the 0th percentile. The CEER figure of 13.4 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 Friedrich KHVL28B35A at $312/yr runs a little cheaper and the Friedrich KCVL36B30A at $389/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 K�Hl KCVL36B30B's $343/yr adds up to roughly $3430 in electricity alone, before purchase price or repairs. At rank #403 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 K�Hl KCVL36B30B 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 $343/yr, here is what the K�Hl KCVL36B30B adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the K�Hl KCVL36B30B costs about $3430. That is roughly $3290 less than a standard model in its class, which would run closer to $6720 over the same ten years.
How the K�Hl KCVL36B30B compares
The room air conditioner class we track runs from $51 to $389 a year. At $343/yr, it runs about $244 a year above the class median of $99, and it is about $292 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $672/yr, the K�Hl KCVL36B30B uses 49% less energy.
What drives its running cost
At 33000 BTU/hr, the K�Hl KCVL36B30B 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. The CEER of 13.4 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 K�Hl KCVL36B30B cheap to run?
Its $343/yr running cost, rank #403 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 K�Hl KCVL36B30B cost per month?
About $28.57 a month, which is the $343 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: 1,847 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $343 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the K�Hl KCVL36B30B 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.
