Model
Midea MAW08U2QWT
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 MAW08U2QWT cost to run per year?
Rank #26 of 404 puts the Midea MAW08U2QWT among the cheapest room air conditioner models we track to keep running, at roughly $70 a year. 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. Size-adjusted, this model beats 91% of room air conditioner models we track on efficiency, one of the stronger results in its class. At a CEER of 16, its combined energy efficiency ratio is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Midea MAW08U1QWT at $70/yr runs a little cheaper and the Midea MAW08V1WBK 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 MAW08U2QWT's $70/yr adds up to roughly $700 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MAW08U2QWT 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 MAW08U2QWT 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 MAW08U2QWT 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 MAW08U2QWT 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 MAW08U2QWT uses 47% less energy.
What drives its running cost
At 8000 BTU/hr, the Midea MAW08U2QWT 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). 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 MAW08U2QWT cheap to run?
Yes. Its $70/yr running cost puts it at rank #26 of 404, below what most room air conditioner models we track cost to run.
How much does the Midea MAW08U2QWT cost per month?
About $5.8 a month, which is the $70 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: 375 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $70 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MAW08U2QWT 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.
