Model
Midea MWEUWA-14CRFN8-BCP0
Rank #307 means 306 of the 404 room air conditioner models we track cost less to run each year; the 25th efficiency percentile means it uses less energy for its size than 25% of those models.
What does the Midea MWEUWA-14CRFN8-BCP0 cost to run per year?
Ranking #307 of 404, the Midea MWEUWA-14CRFN8-BCP0 sits in the pricier half of its class to run, at about $122 a year. It uses 50% less energy than the U.S. federal standard model in its class, which would cost about $244/yr to run, a saving of roughly $122 a year. Adjusted for size, it is only more efficient than 25% of room air conditioner models we track, so part of its running cost comes from its capacity rather than efficiency alone. Its CEER of 16 reflects combined energy efficiency ratio, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Ge PWJV14W**# at $122/yr runs a little cheaper and the Tcl T14WV9S at $122/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-14CRFN8-BCP0's $122/yr adds up to roughly $1220 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MWEUWA-14CRFN8-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 $122/yr, here is what the Midea MWEUWA-14CRFN8-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-14CRFN8-BCP0 costs about $1220. That is roughly $1220 less than a standard model in its class, which would run closer to $2440 over the same ten years.
How the Midea MWEUWA-14CRFN8-BCP0 compares
The room air conditioner class we track runs from $51 to $389 a year. At $122/yr, it runs about $23 a year above the class median of $99, and it is about $71 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $244/yr, the Midea MWEUWA-14CRFN8-BCP0 uses 50% less energy.
What drives its running cost
At 14000 BTU/hr, the Midea MWEUWA-14CRFN8-BCP0 is a large room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, among room air conditioner models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. The CEER of 16 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 Midea MWEUWA-14CRFN8-BCP0 cheap to run?
Not especially. At $122 a year it ranks #307 of 404 room air conditioner models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Midea MWEUWA-14CRFN8-BCP0 cost per month?
Roughly $10.15/mo, spreading the $122/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 656 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $122 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MWEUWA-14CRFN8-BCP0 for its size?
25th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
