Model
Midea MWCUPWHP-09HEFN8-BCL1N
Rank #107 means 106 of the 404 room air conditioner models we track cost less to run each year; the 100th efficiency percentile means it uses less energy for its size than 100% of those models.
What does the Midea MWCUPWHP-09HEFN8-BCL1N cost to run per year?
Ranking #107 of 404, the Midea MWCUPWHP-09HEFN8-BCL1N is in the cheaper half of its class to run, at about $75 a year. It uses 80% less energy than the U.S. federal standard model in its class, which would cost about $376/yr to run, a saving of roughly $301 a year. Normalized for capacity, it ranks ahead of 100% of room air conditioner models we track on efficiency, an exceptional showing for the class. The CEER figure of 17.6 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 MWCUPWHP-09HEFN8-BCL1 at $75/yr runs a little cheaper and the Friedrich KCVS08B10A at $76/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 MWCUPWHP-09HEFN8-BCL1N's $75/yr adds up to roughly $750 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MWCUPWHP-09HEFN8-BCL1N 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 $75/yr, here is what the Midea MWCUPWHP-09HEFN8-BCL1N 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 MWCUPWHP-09HEFN8-BCL1N costs about $750. That is roughly $3010 less than a standard model in its class, which would run closer to $3760 over the same ten years.
How the Midea MWCUPWHP-09HEFN8-BCL1N compares
The room air conditioner class we track runs from $51 to $389 a year. At $75/yr, it runs about $24 a year cheaper than the class median of $99, and it is about $24 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $376/yr, the Midea MWCUPWHP-09HEFN8-BCL1N uses 80% less energy.
What drives its running cost
At 9500 BTU/hr, the Midea MWCUPWHP-09HEFN8-BCL1N 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 17.6, 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 MWCUPWHP-09HEFN8-BCL1N cheap to run?
Yes, relatively. At $75 a year it ranks #107 of 404 room air conditioner models we track, in the cheaper part of its class to run.
How much does the Midea MWCUPWHP-09HEFN8-BCL1N cost per month?
Roughly $6.26/mo, spreading the $75/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 405 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $75 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MWCUPWHP-09HEFN8-BCL1N for its size?
100th percentile once size is factored in, a fairly typical result for the class.
