What does the Midea MWAUQB-12CRFN8-BCN12 cost to run per year?

Ranking #221 of 404, the Midea MWAUQB-12CRFN8-BCN12 runs at roughly $110 a year, neither the cheapest nor the priciest in its class. It uses 39% less energy than the U.S. federal standard model in its class, which would cost about $180/yr to run, a saving of roughly $70 a year. Normalized for capacity, it beats 46% of room air conditioner models we track, an average result for the class. At a CEER of 15.2, 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 MAW12U2QWT at $110/yr runs a little cheaper and the Tcl H12W4KWH at $110/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 MWAUQB-12CRFN8-BCN12's $110/yr adds up to roughly $1100 in electricity alone, before purchase price or repairs.

What it costs you over time

Running cost is an every-year number, so it compounds. At $110/yr, here is what the Midea MWAUQB-12CRFN8-BCN12 adds up to before purchase price, water, or repairs enter the math.

1 year$110
5 years$550
10 years$1100

Left running for a decade at today's US average rate, the Midea MWAUQB-12CRFN8-BCN12 costs about $1100. That is roughly $700 less than a standard model in its class, which would run closer to $1800 over the same ten years.

How the Midea MWAUQB-12CRFN8-BCN12 compares

The room air conditioner class we track runs from $51 to $389 a year. At $110/yr, it runs about $11 a year above the class median of $99, and it is about $59 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $180/yr, the Midea MWAUQB-12CRFN8-BCN12 uses 39% less energy.

What drives its running cost

At 12000 BTU/hr, the Midea MWAUQB-12CRFN8-BCN12 is a mid-size room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. Beyond size, its CEER of 15.2, above 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 MWAUQB-12CRFN8-BCN12 cheap to run?

It is about average. At $110 a year it ranks #221 of 404 room air conditioner models we track, close to the middle of its class on running cost.

How much does the Midea MWAUQB-12CRFN8-BCN12 cost per month?

Roughly $9.16/mo, spreading the $110/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 592 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $110 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.

How efficient is the Midea MWAUQB-12CRFN8-BCN12 for its size?

46th percentile once size is factored in, a fairly typical result for the class.
