Model
Philodeco PIWC-12CRD1(ES)
Rank #231 means 230 of the 404 room air conditioner models we track cost less to run each year; the 43rd efficiency percentile means it uses less energy for its size than 43% of those models.
What does the Philodeco PIWC-12CRD1(ES) cost to run per year?
At $111 a year to run, the Philodeco PIWC-12CRD1(ES) sits close to the middle of its class on cost, ranking #231 of 404 room air conditioner models we track. It uses 38% less energy than the U.S. federal standard model in its class, which would cost about $180/yr to run, a saving of roughly $69 a year. Its 43th size-adjusted efficiency percentile is unremarkable, close to what a typical model in the class scores. 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 1PACV12000 at $111/yr runs a little cheaper and the Richmond RMV12A10A at $111/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-12CRD1(ES)'s $111/yr adds up to roughly $1110 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BD12NWES.
By the numbers
The Philodeco PIWC-12CRD1(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 $111/yr, here is what the Philodeco PIWC-12CRD1(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-12CRD1(ES) costs about $1110. That is roughly $690 less than a standard model in its class, which would run closer to $1800 over the same ten years.
How the Philodeco PIWC-12CRD1(ES) compares
The room air conditioner class we track runs from $51 to $389 a year. At $111/yr, it runs about $12 a year above the class median of $99, and it is about $60 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $180/yr, the Philodeco PIWC-12CRD1(ES) uses 38% less energy.
What drives its running cost
At 12000 BTU/hr, the Philodeco PIWC-12CRD1(ES) is a mid-size room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. The CEER of 15 on this model, above 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). 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-12CRD1(ES) cheap to run?
It is about average. At $111 a year it ranks #231 of 404 room air conditioner models we track, close to the middle of its class on running cost.
How much does the Philodeco PIWC-12CRD1(ES) cost per month?
Roughly $9.28/mo, spreading the $111/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 600 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $111 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Philodeco PIWC-12CRD1(ES) for its size?
43rd percentile once size is factored in, a fairly typical result for the class.
