Decibels are logarithmic: 10 dB less means ten times less sound energy.
What Midea built into the Midea25.
The features Midea states for this series.
The filter sits on top of the unit and attaches with magnets: easy to remove and clean, even often, according to Midea.
The fan wheel comes out for a thorough cleaning, and the evaporator becomes reachable.
When the room has been empty for over 30 minutes, the unit lowers its operating frequency to save energy.

Five questions about the Midea25.
Answer, then read why.
“At -15 °C, a heat pump heats less efficiently than a baseboard.”
False. The Midea25 24,000 has a COP of 2.54 at -15 °C: 2.54 times more heat than electricity. A baseboard gives 1 for 1.
ENERGY STAR, data by AHRI number, Oct. 8, 2026.
“All four Midea25 are ENERGY STAR cold climate certified.”
True. All four sizes: 9,000, 12,000, 18,000 and 24,000.
ENERGY STAR, data by AHRI number, Oct. 8, 2026.
“At 8 °C, the Midea25 9,000 can give more than its rated output.”
True. Up to 13,800 BTU/h at maximum per the NEEP list, for a rated 10,000 BTU/h.
NEEP list, data by AHRI number, Oct. 8, 2026.
“The Midea25 and Midea28 have the same indoor head.”
True. Same ALL EASY PRO head (MSEHU), different outdoor unit.
Midea “High Wall Split” brochure, p. 5.
“According to Midea, the Midea25 heats down to -30 °C.”
False. Midea gives -25 °C for the Midea25; the Midea28 and Midea35 go to -30 °C.
Midea “Residential Heat Pumps” line card.
What people ask us about the Midea25.
No question matches. Write to us or call 514 316-2973.
Down to -25 °C, according to Midea. To go down to -30 °C, look at the Midea28 or the Midea35.
The Midea25 gives a little more certified heat at -8 °C (22,400 vs 22,200 BTU/h) and a higher SEER2 (23.0 vs 21.0). The Midea28 gives much more at its maximum at -15 °C (24,200 vs 19,600 BTU/h) and runs down to -30 °C according to Midea.
Yes, all four sizes, from 9,000 to 24,000 BTU/h, per ENERGY STAR as of October 8, 2026.
LogisVert requires an outdoor unit of at least 12,000 BTU/h nominal cooling, even when the 9,000 is ENERGY STAR certified.
At Midea, Wi-Fi control of wall units goes through an optional module, with the Midea SmartHome app. The quote says what is included.
For the first owner of a single-family home: 7 years on the compressor and 5 years on parts, or 12 years on both if the unit is registered within 60 days. Any other use: 5 years compressor, 1 year parts. Next owner: 5 and 5. Midea excludes labour and refrigerant.
On the ALL EASY PRO units (Midea25, 28 and 35), the filter is on top and held by magnets, according to Midea: take it out and rinse it. For a full cleaning of the unit, see our wall unit cleaning service.
