Model
Philodeco PIWC-10CRD1(ES)
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 Philodeco PIWC-10CRD1(ES) cost to run per year?
Do the math and the Philodeco PIWC-10CRD1(ES)'s $93/yr puts it at rank #143 of 404, on the cheaper side of the class. 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. Normalized for capacity, it beats 65% of room air conditioner models we track, a better-than-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 Perfect Aire 1PACV10000 at $93/yr runs a little cheaper and the Richmond RMV10A10A 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 Philodeco PIWC-10CRD1(ES)'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 Philodeco PIWC-10CRD1(ES) 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 Philodeco PIWC-10CRD1(ES) adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Philodeco PIWC-10CRD1(ES) 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 Philodeco PIWC-10CRD1(ES) 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 Philodeco PIWC-10CRD1(ES) uses 38% less energy.
What drives its running cost
At 10000 BTU/hr, the Philodeco PIWC-10CRD1(ES) 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). 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 Philodeco PIWC-10CRD1(ES) 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 Philodeco PIWC-10CRD1(ES) 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 Philodeco PIWC-10CRD1(ES) for its size?
65th percentile once size is factored in, a fairly typical result for the class.
