Model
Frigidaire FHWW085WE1
Rank #51 means 50 of the 404 room air conditioner models we track cost less to run each year; the 85th efficiency percentile means it uses less energy for its size than 85% of those models.
What does the Frigidaire FHWW085WE1 cost to run per year?
Rank #51 of 404 puts the Frigidaire FHWW085WE1 among the cheapest room air conditioner models we track to keep running, at roughly $74 a year. It uses 38% less energy than the U.S. federal standard model in its class, which would cost about $120/yr to run, a saving of roughly $46 a year. Its size-adjusted efficiency percentile of 85 sits well above the class median, a clearly above-average efficiency result. The CEER figure of 15 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 CCV08A10A at $74/yr runs a little cheaper and the Frigidaire Gallery GHWQ083WC1 at $74/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 Frigidaire FHWW085WE1's $74/yr adds up to roughly $740 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BD08NWES.
By the numbers
The Frigidaire FHWW085WE1 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 $74/yr, here is what the Frigidaire FHWW085WE1 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Frigidaire FHWW085WE1 costs about $740. That is roughly $460 less than a standard model in its class, which would run closer to $1200 over the same ten years.
How the Frigidaire FHWW085WE1 compares
The room air conditioner class we track runs from $51 to $389 a year. At $74/yr, it runs about $25 a year cheaper than the class median of $99, and it is about $23 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $120/yr, the Frigidaire FHWW085WE1 uses 38% less energy.
What drives its running cost
At 8000 BTU/hr, the Frigidaire FHWW085WE1 is a small room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Its CEER of 15, above 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 Frigidaire FHWW085WE1 cheap to run?
Yes. Its $74/yr running cost puts it at rank #51 of 404, below what most room air conditioner models we track cost to run.
How much does the Frigidaire FHWW085WE1 cost per month?
About $6.19 a month, which is the $74 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: 400 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $74 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Frigidaire FHWW085WE1 for its size?
85th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
