Model
Midea 1010451379
Rank #221 means 220 of the 404 room air conditioner models we track cost less to run each year; the 46th efficiency percentile means it uses less energy for its size than 46% of those models.
What does the Midea 1010451379 cost to run per year?
Ranking #221 of 404, the Midea 1010451379 runs at roughly $110 a year, neither the cheapest nor the priciest in its class. It uses 39% less energy than the U.S. federal standard model in its class, which would cost about $180/yr to run, a saving of roughly $70 a year. Normalized for capacity, it beats 46% of room air conditioner models we track, an average result for the class. The CEER figure of 15.2 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 House Kobo KOBOGJC12BU at $109/yr runs a little cheaper and the Midea 1014278205 at $110/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 1010451379's $110/yr adds up to roughly $1100 in electricity alone, before purchase price or repairs.

By the numbers
The Midea 1010451379 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 $110/yr, here is what the Midea 1010451379 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 1010451379 costs about $1100. That is roughly $700 less than a standard model in its class, which would run closer to $1800 over the same ten years.
How the Midea 1010451379 compares
The room air conditioner class we track runs from $51 to $389 a year. At $110/yr, it runs about $11 a year above the class median of $99, and it is about $59 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 Midea 1010451379 uses 39% less energy.
What drives its running cost
At 12000 BTU/hr, the Midea 1010451379 is a mid-size room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. Its CEER of 15.2, 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 Midea 1010451379 cheap to run?
It is about average. At $110 a year it ranks #221 of 404 room air conditioner models we track, close to the middle of its class on running cost.
How much does the Midea 1010451379 cost per month?
Roughly $9.16/mo, spreading the $110/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 592 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $110 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea 1010451379 for its size?
46th percentile once size is factored in, a fairly typical result for the class.
