Model
Midea MAW08V1QWT
Rank #51 means 50 of the 404 room air conditioner models we track cost less to run each year; the 85th efficiency percentile means it uses less energy for its size than 85% of those models.
What does the Midea MAW08V1QWT cost to run per year?
The Midea MAW08V1QWT runs for about $74 a year, landing it near the bottom of the cost table at rank #51 of 404 room air conditioner models we track. It uses 38% less energy than the U.S. federal standard model in its class, which would cost about $120/yr to run, a saving of roughly $46 a year. Few room air conditioner models we track beat it on size-adjusted efficiency; it edges out 85% of the class once capacity is normalized. Its CEER of 15 reflects combined energy efficiency ratio, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Midea MAW08S1VWWT-T at $74/yr runs a little cheaper and the Midea MAW08V1QWT-S at $74/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 MAW08V1QWT's $74/yr adds up to roughly $740 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BD08NWES.
By the numbers
The Midea MAW08V1QWT 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 $74/yr, here is what the Midea MAW08V1QWT 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 MAW08V1QWT costs about $740. That is roughly $460 less than a standard model in its class, which would run closer to $1200 over the same ten years.
How the Midea MAW08V1QWT compares
The room air conditioner class we track runs from $51 to $389 a year. At $74/yr, it runs about $25 a year cheaper than the class median of $99, and it is about $23 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $120/yr, the Midea MAW08V1QWT uses 38% less energy.
What drives its running cost
At 8000 BTU/hr, the Midea MAW08V1QWT 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 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 MAW08V1QWT cheap to run?
Yes. Its $74/yr running cost puts it at rank #51 of 404, below what most room air conditioner models we track cost to run.
How much does the Midea MAW08V1QWT cost per month?
About $6.19 a month, which is the $74 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: 400 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $74 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MAW08V1QWT for its size?
85th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
