What Midea built into the Midea35.
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 Midea35.
Answer, then read why.
“The Midea35 9,000 has the same outdoor unit format as the 12,000.”
True. Same dimensions and weight (45.2 kg), per Midea’s tables. Its certified figures differ: SEER2 33.3 versus 29.4.
Midea “High Wall Split” brochure, p. 1.
““35” means 35 SEER2 at every size.”
False. It is Midea’s 6,000 figure; our sizes reach 33.3.
Midea “High Wall Split” brochure ; ENERGY STAR, data by AHRI number, Oct. 8, 2026.
“A heat pump can deliver more than 4 kWh of heat per kWh of electricity.”
True. Rated COP of 4.41 for the Midea35 18,000 at 8 °C.
NEEP list, data by AHRI number, Oct. 8, 2026.
“The Midea35 comes in 24,000 BTU/h.”
False. According to Midea’s line card, the series spans 1/2 to 1 1/2 tons: 9,000, 12,000 and 18,000 in our catalogue.
Midea “Residential Heat Pumps” line card.
“At -15 °C, the Midea35 can no longer reach its rated output.”
False. It can still exceed it: up to 13,500 BTU/h at maximum at 9,000, for a rated 12,000 BTU/h. Its maximum output still drops with the cold (17,200 BTU/h at 8 °C).
NEEP list, data by AHRI number, Oct. 8, 2026.
What people ask us about the Midea35.
No question matches. Write to us or call 514 316-2973.
Both heat down to -30 °C according to Midea. The Midea35 uses the least in summer (SEER2 up to 33.3) and gives the highest maximum heat at -15 °C. The Midea28 gives more certified heat at -8 °C in 9,000 and 12,000, and also comes in 24,000 and 33,000 BTU/h.
SEER2 measures efficiency over a cooling season: the higher it is, the less the unit uses for the same cooling. 33.3 is the highest of our Midea wall units, on the 9,000 BTU/h Midea35.
We offer the Midea35 in 9,000, 12,000 and 18,000 BTU/h. For 24,000 or 33,000, look at the Midea28, or the Midea25 in 24,000.
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.
