Who it's for
Adding heating and cooling to a room, addition or zone without ductwork.
The standout number
COP 2.03 at 5°F — it keeps working efficiently when it's frigid.
The catch
A DIY-listed unit still needs a licensed pro for the refrigerant hookup, permit and warranty.

Frequently asked questions
Does the Midea MO1BS-H30B-2A still heat in cold weather?
At 5°F it runs at a COP of 2.03, meaning it delivers 2.03 units of heat for every unit of electricity it uses. Its certified heating output at 5°F is 20,000 BTU per hour. It is not on the ENERGY STAR Cold Climate list, so check sizing for very cold weather.
What does the Midea MO1BS-H30B-2A cost to run?
About $19.82 per MMBtu of delivered heat at the U.S. average electricity price, roughly 64% less than electric resistance heat. Your local electricity price changes the number — use our operating-cost calculator to run it with your rate.
What refrigerant does the Midea MO1BS-H30B-2A use?
R-454B, which has a global-warming potential (GWP) of about 466. This is one of the lower-GWP refrigerants replacing R-410A.
Where can I buy the Midea MO1BS-H30B-2A?
It's listed for sale online at The Home Depot. A licensed pro should still handle the refrigerant hookup, permit and warranty.
Sources. Performance ratings from the AHRI Directory (cited by reference number 216607255; not a verbatim mirror) and ENERGY STAR certification data. Operating-cost ($/MMBtu), savings and percentile figures are computed by Verified HVAC Data from published ratings and EIA U.S. average energy prices — see our methodology. Refrigerant GWP is the IPCC value for that refrigerant. 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.
