Model
Midea MAW10RV1CCWT
Rank #143 means 142 of the 404 room air conditioner models we track cost less to run each year; the 65th efficiency percentile means it uses less energy for its size than 65% of those models.
What does the Midea MAW10RV1CCWT cost to run per year?
At roughly $93 a year to run, ranking #143 of 404, the Midea MAW10RV1CCWT costs less than the typical room air conditioner model we track. It uses 38% less energy than the U.S. federal standard model in its class, which would cost about $150/yr to run, a saving of roughly $57 a year. Capacity-normalized, it ranks ahead of 65% of room air conditioner models we track, a reasonably strong result for the class. The CEER figure of 15 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 1014634875 at $93/yr runs a little cheaper and the Midea MAW10RV1CWT at $93/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 MAW10RV1CCWT's $93/yr adds up to roughly $930 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BD10NWES.
By the numbers
The Midea MAW10RV1CCWT 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 $93/yr, here is what the Midea MAW10RV1CCWT 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 MAW10RV1CCWT costs about $930. That is roughly $570 less than a standard model in its class, which would run closer to $1500 over the same ten years.
How the Midea MAW10RV1CCWT compares
The room air conditioner class we track runs from $51 to $389 a year. At $93/yr, it runs about $6 a year cheaper than the class median of $99, and it is about $42 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $150/yr, the Midea MAW10RV1CCWT uses 38% less energy.
What drives its running cost
At 10000 BTU/hr, the Midea MAW10RV1CCWT 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. The CEER of 15 on this model, above 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 MAW10RV1CCWT cheap to run?
Yes. Its $93/yr running cost puts it at rank #143 of 404, below what most room air conditioner models we track cost to run.
How much does the Midea MAW10RV1CCWT cost per month?
About $7.73 a month, which is the $93 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: 500 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $93 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MAW10RV1CCWT for its size?
65th percentile once size is factored in, a fairly typical result for the class.
