Model
Midea MAT10R1FWTK
Rank #198 means 197 of the 404 room air conditioner models we track cost less to run each year; the 51st efficiency percentile means it uses less energy for its size than 51% of those models.
What does the Midea MAT10R1FWTK cost to run per year?
Among the 404 room air conditioner models we track, the Midea MAT10R1FWTK's $99/yr running cost ranks it #198, close to dead center. It uses 47% less energy than the U.S. federal standard model in its class, which would cost about $186/yr to run, a saving of roughly $87 a year. Its size-adjusted efficiency percentile of 51 lands in the middle of the pack once capacity is accounted for. The CEER figure of 14.1 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 K�Hl+ KHVS10B11B at $98/yr runs a little cheaper and the Midea MAT10R1SWTK at $99/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 MAT10R1FWTK's $99/yr adds up to roughly $990 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MAT10R1FWTK 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 $99/yr, here is what the Midea MAT10R1FWTK 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 MAT10R1FWTK costs about $990. That is roughly $870 less than a standard model in its class, which would run closer to $1860 over the same ten years.
How the Midea MAT10R1FWTK compares
The room air conditioner class we track runs from $51 to $389 a year. At $99/yr, it sits right on the class median of $99, and it is about $48 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $186/yr, the Midea MAT10R1FWTK uses 47% less energy.
What drives its running cost
At 10000 BTU/hr, the Midea MAT10R1FWTK is a small room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. The CEER of 14.1 on this model, below the class median of 15, measures combined energy efficiency ratio; it is the number to compare directly against another model's CEER if capacity is similar.
- 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 MAT10R1FWTK cheap to run?
Roughly, yes. Its $99/yr figure is close to the class median, ranking #198 of 404, neither a bargain nor a splurge on running cost.
How much does the Midea MAT10R1FWTK cost per month?
About $8.23 a month, which is the $99 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: 532 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $99 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MAT10R1FWTK for its size?
51st percentile once size is factored in, a fairly typical result for the class.
