What actually decides this purchase
We publish 75 units at 10,000 BTU. They run within $27 a year of each other — but they sell for $351 to $631, a 1.8× spread. Efficiency is not what decides this purchase at 10,000 BTU; price, noise and whether it fits your window are. Here is where this unit lands.
We have no tracked price for this unit, so here is the rule instead. At 10,000 BTU the field runs $351 to $631, median $435, and every one of them runs within $27 a year of every other — so price is the decision and efficiency is the tiebreak. On the certified specs we do hold, this one ranks 1st of 75 in its class. If the price you are quoted is above $435, buy something else. Worth comparing against the PHILODECO PIWC-10CRD1(ES) at $351 and the Friedrich CCV10A10A at 32 dBA for $588.

Fit & install — does it fit your window?
Efficiency & running cost — computed by Verified HVAC Data
Worth keeping in proportion: every unit in the 10,000 BTU class runs within $27 a year of every other. The gap between the cheapest and dearest to buy at this size is 10× larger. Efficiency is the smallest number on this page, which is why it is not at the top of it.
Refrigerant & identity
Brand, warranty & reliability
Midea is one of the two largest Chinese HVAC OEMs (it builds many US budget brands) offering competitive value and quiet operation, but reliability varies by model and full warranty terms require product registration within 90 days.
Reliability is our read of published brand assessments (source), not a certified rating — real-world dependability hinges on a correct install more than the brand. Warranty terms are the manufacturer's (policy) and almost always require online registration within 60–90 days for the full length.

Frequently asked questions
Is 9,500 BTU right for my room, or should I size up?
About 450 square feet is the guide figure, and 75 certified units sit on that shelf. The next shelf up is 11,000 BTU (4 units), about 450 sq ft. Below it, 9,000 BTU (6 units) covers about 400 sq ft. Between two shelves, take the smaller one: oversizing is the usual reason a unit cools but leaves the room clammy, which our sizing calculator explains.
Does the Midea MAH09N1AGR heat as well as cool?
Yes — it is certified with a heating mode, so it works as a shoulder-season heater as well as an air conditioner. Only 30 of the 389 room ACs we publish do. It is supplemental heat for one room, not a replacement for a home heating system.
Does the Midea MAH09N1AGR qualify for efficiency rebates?
It meets ENERGY STAR Most Efficient, the top tier some utility rebate programmes require. 29 of the 75 units in its 10,000 BTU class reach that tier, so it is one of several options at this size. Rebates are set by your state and utility, not by the manufacturer — check the programmes for your area.
Will the Midea MAH09N1AGR fit my window?
The certification record doesn't publish reliable full dimensions for this unit, so measure your opening and compare against the seller's listing before you buy.
Sources. Certification and CEER from ENERGY STAR room-AC data and the DOE compliance certification database. Cooling capacity, dimensions and refrigerant are the manufacturer-certified values. Annual running cost, suggested room size and the percentile are computed by Verified HVAC Data from published ratings and EIA U.S. average electricity prices — see our methodology. Refrigerant GWP is the IPCC value. We publish no star ratings and take no payment for placement. "Not published" means the source registry doesn't disclose it — we never fill a spec with a guess.
