Model
Midea MAW08V1KWT-A
Rank #44 means 43 of the 404 room air conditioner models we track cost less to run each year; the 87th efficiency percentile means it uses less energy for its size than 87% of those models.
What does the Midea MAW08V1KWT-A cost to run per year?
Among the 404 room air conditioner models we track, the Midea MAW08V1KWT-A's $72/yr running cost ranks it #44, comfortably in the cheap-to-run group. It uses 37% less energy than the U.S. federal standard model in its class, which would cost about $114/yr to run, a saving of roughly $42 a year. Few room air conditioner models we track beat it on size-adjusted efficiency; it edges out 87% of the class once capacity is normalized. The CEER figure of 15.1 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 Lg LW8022IVSM at $72/yr runs a little cheaper and the Midea MAW08V1KYWT-S at $72/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 MAW08V1KWT-A's $72/yr adds up to roughly $720 in electricity alone, before purchase price or repairs.
Also sold as: Midea MAW08V1KYWT-S, Midea MWFUQB-8CRFN8-BCN11.
By the numbers
The Midea MAW08V1KWT-A 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 $72/yr, here is what the Midea MAW08V1KWT-A 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 MAW08V1KWT-A costs about $720. That is roughly $420 less than a standard model in its class, which would run closer to $1140 over the same ten years.
How the Midea MAW08V1KWT-A compares
The room air conditioner class we track runs from $51 to $389 a year. At $72/yr, it runs about $27 a year cheaper than the class median of $99, and it is about $21 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $114/yr, the Midea MAW08V1KWT-A uses 37% less energy.
What drives its running cost
At 7800 BTU/hr, the Midea MAW08V1KWT-A 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. Its CEER of 15.1, 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). Two units with the same BTU rating can post very different running costs, and CEER is the figure that explains most of that gap.
- BTU cooling capacity. BTU rating scales with room size, and it is usually the first driver of an air conditioner's running cost, ahead of its CEER figure.
- Thermostat and mode usage. How the unit is actually operated, thermostat cycling versus a fixed setting, moves real electricity use more than the rated BTU or CEER figure alone.
Common questions
Is the Midea MAW08V1KWT-A cheap to run?
Yes. Its $72/yr running cost puts it at rank #44 of 404, below what most room air conditioner models we track cost to run.
How much does the Midea MAW08V1KWT-A cost per month?
About $5.99 a month, which is the $72 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 387 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $72 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MAW08V1KWT-A for its size?
87th 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.
