How much does the Midea MAH09B1AGR cost to run?
About 13¢ an hour of cooling, or $32.25 for 30 days at 8 hours a day (less once the compressor cycles off).
DOE's record lists 740 W of electrical input while cooling. Electricity at 18.16¢/kWh, the US residential average for August 2026 (EIA Electric Power Monthly, table 5.6.A). Each 1¢/kWh you pay above or below 18.16¢ moves the 8 hour figure by 6¢.
How does the Midea MAH09B1AGR rank in its DOE class?
Its DOE class (window ACs with heat pump, less than 20,000 BTU/h) has 19 models certified to DOE. Its CEER of 17.6 is tied for 1st of the 19, and 17% above their median of 15.1. On cost, the same 9,500 BTU/h at their median CEER would cost about $37.59 for 30 days at 8 hours, $5.34 more than this one.
