Model
Midea MAW14RV1CCWT
Rank #319 means 318 of the 404 room air conditioner models we track cost less to run each year; the 23rd efficiency percentile means it uses less energy for its size than 23% of those models.
What does the Midea MAW14RV1CCWT cost to run per year?
At about $130 a year, the Midea MAW14RV1CCWT costs more to run than most room air conditioner models we track, rank #319 of 404. It uses 40% less energy than the U.S. federal standard model in its class, which would cost about $217/yr to run, a saving of roughly $87 a year. Its size-adjusted efficiency percentile of 23 suggests its capacity is doing more work than its efficiency to keep the headline cost down. At a CEER of 15, 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 MAW14R1VWT at $130/yr runs a little cheaper and the Midea MAW14RV1CWT at $130/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 MAW14RV1CCWT's $130/yr adds up to roughly $1300 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MAW14RV1CCWT 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 $130/yr, here is what the Midea MAW14RV1CCWT 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 MAW14RV1CCWT costs about $1300. That is roughly $870 less than a standard model in its class, which would run closer to $2170 over the same ten years.
How the Midea MAW14RV1CCWT compares
The room air conditioner class we track runs from $51 to $389 a year. At $130/yr, it runs about $31 a year above the class median of $99, and it is about $79 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $217/yr, the Midea MAW14RV1CCWT uses 40% less energy.
What drives its running cost
At 14000 BTU/hr, the Midea MAW14RV1CCWT is a large room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, and larger room air conditioner models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. Its CEER of 15, 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 MAW14RV1CCWT cheap to run?
Its $130/yr running cost, rank #319 of 404, is above what most room air conditioner models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Midea MAW14RV1CCWT cost per month?
About $10.83 a month, which is the $130 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: 700 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $130 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MAW14RV1CCWT for its size?
23rd percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
