Model
Midea MWEUWA-12CRFN8-BCP0
Rank #207 means 206 of the 404 room air conditioner models we track cost less to run each year; the 49th efficiency percentile means it uses less energy for its size than 49% of those models.
What does the Midea MWEUWA-12CRFN8-BCP0 cost to run per year?
The Midea MWEUWA-12CRFN8-BCP0 costs about $104 a year to run, a middle-of-the-pack figure at rank #207 of 404. It uses 47% less energy than the U.S. federal standard model in its class, which would cost about $197/yr to run, a saving of roughly $93 a year. Once capacity is factored in, its efficiency percentile of 49 is fairly typical for the class, neither a standout nor a laggard. The CEER figure of 16 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 Midea MAW12V1WWT-T at $104/yr runs a little cheaper and the Tcl T12WV4S at $104/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 Midea MWEUWA-12CRFN8-BCP0's $104/yr adds up to roughly $1040 in electricity alone, before purchase price or repairs.
Also sold as: Midea MAW12V1WBK.
By the numbers
The Midea MWEUWA-12CRFN8-BCP0 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 $104/yr, here is what the Midea MWEUWA-12CRFN8-BCP0 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Midea MWEUWA-12CRFN8-BCP0 costs about $1040. That is roughly $930 less than a standard model in its class, which would run closer to $1970 over the same ten years.
How the Midea MWEUWA-12CRFN8-BCP0 compares
The room air conditioner class we track runs from $51 to $389 a year. At $104/yr, it runs about $5 a year above the class median of $99, and it is about $53 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $197/yr, the Midea MWEUWA-12CRFN8-BCP0 uses 47% less energy.
What drives its running cost
At 12000 BTU/hr, the Midea MWEUWA-12CRFN8-BCP0 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. Beyond size, its CEER of 16, above the class median of 15, is the class's own efficiency yardstick, combined energy efficiency ratio, and it is what separates two similarly sized models with different running costs.
- 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 Midea MWEUWA-12CRFN8-BCP0 cheap to run?
It is about average. At $104 a year it ranks #207 of 404 room air conditioner models we track, close to the middle of its class on running cost.
How much does the Midea MWEUWA-12CRFN8-BCP0 cost per month?
Roughly $8.7/mo, spreading the $104/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 563 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $104 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MWEUWA-12CRFN8-BCP0 for its size?
49th percentile once size is factored in, a fairly typical result for the class.
