Model
Midea MAW14V1YWT-S
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 MAW14V1YWT-S cost to run per year?
Do the math and the Midea MAW14V1YWT-S's $130/yr puts it at rank #319 of 404, on the pricier side of the class. 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. Normalized for capacity, it beats only 23% of room air conditioner models we track, a below-average efficiency result. 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 MAW14S1VWWT-T at $130/yr runs a little cheaper and the Midea MWCUWA-14CRFN8-BCN10 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 MAW14V1YWT-S's $130/yr adds up to roughly $1300 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MAW14V1YWT-S 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 MAW14V1YWT-S 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 MAW14V1YWT-S 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 MAW14V1YWT-S 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 MAW14V1YWT-S uses 40% less energy.
What drives its running cost
At 14000 BTU/hr, the Midea MAW14V1YWT-S is a large room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up. 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). 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 MAW14V1YWT-S cheap to run?
Not especially. At $130 a year it ranks #319 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 MAW14V1YWT-S cost per month?
Roughly $10.83/mo, spreading the $130/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 700 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $130 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MAW14V1YWT-S 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.
