What does the Midea 1014278205 cost to run per year?

Among the 404 room air conditioner models we track, the Midea 1014278205's $110/yr running cost ranks it #221, close to dead center. 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. Capacity-normalized, it ranks ahead of 46% of room air conditioner models we track, right in the class's middle band. 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 1010451379 at $110/yr runs a little cheaper and the Midea MAW12U1QWT 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 1014278205'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 1014278205 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 1014278205 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 1014278205 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 1014278205 uses 39% less energy.

What drives its running cost

At 12000 BTU/hr, the Midea 1014278205 is a mid-size room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. 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). 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 1014278205 cheap to run?

Roughly, yes. Its $110/yr figure is close to the class median, ranking #221 of 404, neither a bargain nor a splurge on running cost.

How much does the Midea 1014278205 cost per month?

About $9.16 a month, which is the $110 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: 592 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $110 a year. It covers electricity only, not the purchase price, water, or installation.

How efficient is the Midea 1014278205 for its size?

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