Model
Midea MAH09H1AGR
Rank #107 means 106 of the 404 room air conditioner models we track cost less to run each year; the 100th efficiency percentile means it uses less energy for its size than 100% of those models.
What does the Midea MAH09H1AGR cost to run per year?
Among the 404 room air conditioner models we track, the Midea MAH09H1AGR sits in the below-average-cost group, rank #107, at roughly $75 a year. It uses 80% less energy than the U.S. federal standard model in its class, which would cost about $376/yr to run, a saving of roughly $301 a year. Size-adjusted, this model beats 100% of room air conditioner models we track on efficiency, a standout even among the class's efficient models. At a CEER of 17.6, 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 MAH09B1AGR at $75/yr runs a little cheaper and the Midea MAH09N1AGR at $75/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 MAH09H1AGR's $75/yr adds up to roughly $750 in electricity alone, before purchase price or repairs.
Also sold as: Midea MAH09B1AGR.
By the numbers
The Midea MAH09H1AGR 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 $75/yr, here is what the Midea MAH09H1AGR 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 MAH09H1AGR costs about $750. That is roughly $3010 less than a standard model in its class, which would run closer to $3760 over the same ten years.
How the Midea MAH09H1AGR compares
The room air conditioner class we track runs from $51 to $389 a year. At $75/yr, it runs about $24 a year cheaper than the class median of $99, and it is about $24 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $376/yr, the Midea MAH09H1AGR uses 80% less energy.
What drives its running cost
At 9500 BTU/hr, the Midea MAH09H1AGR is a small room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. The CEER of 17.6 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 MAH09H1AGR cheap to run?
Yes. Its $75/yr running cost puts it at rank #107 of 404, below what most room air conditioner models we track cost to run.
How much does the Midea MAH09H1AGR cost per month?
About $6.26 a month, which is the $75 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: 405 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $75 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MAH09H1AGR for its size?
100th percentile once size is factored in, a fairly typical result for the class.
