A design thought out for efficiency and comfort

Its thin panel fits easily into suspended ceilings, preserving the beauty and discretion of the space.

GA Inverter Technology: Modulated Performance

Equipped with Midea's GA Inverter technology, the cassette continuously adjusts the compressor power according to the detected ambient temperature. Result:

• Increased energy efficiency , with a SEER2 of 23.0 and a HSPF2 of 10.0 , Energy Star Cold Climate certified.

• Power consumption reduced by up to 60% in ECO mode.

• A stable temperature without sudden variations, for constant comfort.

Comfort in all seasons

Designed for the Quebec climate, this unit maintains a heating capacity down to -30°C , a crucial asset for winters in Montreal, Laval, Longueuil, the North Shore and the South Shore .
The 8°C Heating mode allows you to maintain a minimum temperature in second homes or unoccupied chalets, avoiding any risk of frost.

A jewel of silent technology

Controlled noise level

With an indoor noise level of only 24 to 41 dB(A) , the MIDEA 1-Way Cassette operates almost silently. For comparison, that's barely more than a whisper.
The outdoor unit, meanwhile, boasts 56 dB(A) —a remarkable performance for a compact 12,000 BTU system.

“Silent Mode” and “Follow Me” function

Silent Mode automatically reduces fan speed for virtually inaudible operation at night.
The Follow Me function adjusts the temperature according to the position of the remote control, guaranteeing incomparable precision and personalized comfort.
