Model
Midea MAW25R2VWT
Rank #381 means 380 of the 404 room air conditioner models we track cost less to run each year; the 5th efficiency percentile means it uses less energy for its size than 5% of those models.
What does the Midea MAW25R2VWT cost to run per year?
The Midea MAW25R2VWT costs about $251 a year to run, sitting well up the cheapest-to-run leaderboard, rank #381 of 404. It uses 41% less energy than the U.S. federal standard model in its class, which would cost about $426/yr to run, a saving of roughly $175 a year. Its 5th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. Its CEER of 13.3 reflects combined energy efficiency ratio, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Midea MAW24S2YWT-S at $251/yr runs a little cheaper and the Midea MWCUWH-24CRFN8-MCM3 at $251/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 MAW25R2VWT's $251/yr adds up to roughly $2510 in electricity alone, before purchase price or repairs.
Also sold as: Comfort Aire RADS-253R03.
By the numbers
The Midea MAW25R2VWT 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 $251/yr, here is what the Midea MAW25R2VWT 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 MAW25R2VWT costs about $2510. That is roughly $1750 less than a standard model in its class, which would run closer to $4260 over the same ten years.
How the Midea MAW25R2VWT compares
The room air conditioner class we track runs from $51 to $389 a year. At $251/yr, it runs about $152 a year above the class median of $99, and it is about $200 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $426/yr, the Midea MAW25R2VWT uses 41% less energy.
What drives its running cost
At 24000 BTU/hr, the Midea MAW25R2VWT 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. Beyond size, its CEER of 13.3, below 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). CEER captures cooling output per watt, including standby power; a higher CEER means less electricity for the same BTU of cooling.
- BTU cooling capacity. A higher-BTU unit is sized for a bigger room and generally uses more electricity per hour of operation than a smaller unit, regardless of efficiency.
- Thermostat and mode usage. Running on a fixed low temperature around the clock uses far more energy than using a thermostat setting, eco mode, or a timer to match cooling to when the room is actually occupied.
Common questions
Is the Midea MAW25R2VWT cheap to run?
Not especially. At $251 a year it ranks #381 of 404 room air conditioner models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Midea MAW25R2VWT cost per month?
Roughly $20.93/mo, spreading the $251/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 1,353 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $251 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MAW25R2VWT for its size?
5th 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.
