Model
Midea 1010451315
Rank #26 means 25 of the 404 room air conditioner models we track cost less to run each year; the 91st efficiency percentile means it uses less energy for its size than 91% of those models.
What does the Midea 1010451315 cost to run per year?
The Midea 1010451315 costs about $70 a year to run and sits near the top of the cheapest-to-run leaderboard, rank #26 of 404. It uses 47% less energy than the U.S. federal standard model in its class, which would cost about $131/yr to run, a saving of roughly $61 a year. Efficiency-wise, once capacity is accounted for, it beats 91% of the class, a solidly strong result rather than a size-driven fluke. 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 Ge PWJV08W**# at $70/yr runs a little cheaper and the Midea 1014242943 at $70/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 1010451315's $70/yr adds up to roughly $700 in electricity alone, before purchase price or repairs.

By the numbers
The Midea 1010451315 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 $70/yr, here is what the Midea 1010451315 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 1010451315 costs about $700. That is roughly $610 less than a standard model in its class, which would run closer to $1310 over the same ten years.
How the Midea 1010451315 compares
The room air conditioner class we track runs from $51 to $389 a year. At $70/yr, it runs about $29 a year cheaper than the class median of $99, and it is about $19 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $131/yr, the Midea 1010451315 uses 47% less energy.
What drives its running cost
At 8000 BTU/hr, the Midea 1010451315 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. 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 1010451315 cheap to run?
Yes, relatively. At $70 a year it ranks #26 of 404 room air conditioner models we track, in the cheaper part of its class to run.
How much does the Midea 1010451315 cost per month?
Roughly $5.8/mo, spreading the $70/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 375 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $70 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea 1010451315 for its size?
91st percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
