Model
Perfect Aire 1PACV10000
Rank #143 means 142 of the 404 room air conditioner models we track cost less to run each year; the 65th efficiency percentile means it uses less energy for its size than 65% of those models.
What does the Perfect Aire 1PACV10000 cost to run per year?
The Perfect Aire 1PACV10000 is a relatively cheap runner for its class: about $93 a year, rank #143 of 404. It uses 38% less energy than the U.S. federal standard model in its class, which would cost about $150/yr to run, a saving of roughly $57 a year. Once capacity is factored in, its 65th efficiency percentile puts it ahead of most peers in its class. At a CEER of 15, 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 Perfect Aire 1PACU10000 at $93/yr runs a little cheaper and the Philodeco PIWC-10CRD1(ES) at $93/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 Perfect Aire 1PACV10000's $93/yr adds up to roughly $930 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BD10NWES.
By the numbers
The Perfect Aire 1PACV10000 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 $93/yr, here is what the Perfect Aire 1PACV10000 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Perfect Aire 1PACV10000 costs about $930. That is roughly $570 less than a standard model in its class, which would run closer to $1500 over the same ten years.
How the Perfect Aire 1PACV10000 compares
The room air conditioner class we track runs from $51 to $389 a year. At $93/yr, it runs about $6 a year cheaper than the class median of $99, and it is about $42 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $150/yr, the Perfect Aire 1PACV10000 uses 38% less energy.
What drives its running cost
At 10000 BTU/hr, the Perfect Aire 1PACV10000 is a small room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, and smaller room air conditioner models generally cost less to run for the same job, all else being equal. 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). CEER captures cooling output per watt, including standby power; a higher CEER means less electricity for the same BTU of cooling.
- BTU cooling capacity. A higher-BTU unit is sized for a bigger room and generally uses more electricity per hour of operation than a smaller unit, regardless of efficiency.
- Thermostat and mode usage. Running on a fixed low temperature around the clock uses far more energy than using a thermostat setting, eco mode, or a timer to match cooling to when the room is actually occupied.
Common questions
Is the Perfect Aire 1PACV10000 cheap to run?
Yes, relatively. At $93 a year it ranks #143 of 404 room air conditioner models we track, in the cheaper part of its class to run.
How much does the Perfect Aire 1PACV10000 cost per month?
Roughly $7.73/mo, spreading the $93/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 500 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $93 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Perfect Aire 1PACV10000 for its size?
65th percentile once size is factored in, a fairly typical result for the class.
