Wall-mounted heat pump guide
Choosing the right wall-mounted heat pump
Why choose a wall-mounted heat pump?
A wall-mounted heat pump, also called a ductless mini-split, connects an indoor unit mounted on the wall to an outdoor unit with a simple refrigerant line. It’s the ideal solution when there’s no ductwork, which is the case for most condos, plexes and many houses in Montréal.
- No ducts: a single opening in the exterior wall is enough.
- Quick installation: usually done in one day.
- High efficiency: up to 27.4 SEER2 in our catalogue, thanks to variable-speed (inverter) compressors.
- Four-season comfort: heating, cooling and dehumidifying with the same unit.
- Remote control: many models offer built-in or optional WiFi.
To heat several separate rooms, a multi-zone heat pump may be more practical; if your house already has ductwork, compare with a central heat pump.
Which size: 9,000, 12,000, 18,000 or 24,000 BTU?
Capacity (in BTU) must match the space to heat, not just its floor area: insulation, windows, ceiling height and wind exposure matter just as much. Here are the most common uses, to be confirmed during the quote.
| Capacity | Most common use |
|---|---|
| 9,000 BTU | Bedroom, office or small closed room |
| 12,000 BTU | Living room or main room of a condo or apartment |
| 15,000 – 18,000 BTU | Open kitchen–living–dining area |
| 24,000 BTU | Large open area or a mostly open floor |
| 30,000 – 36,000 BTU | Very large open spaces (Ouellet Harmony series) |
A unit that’s too small will struggle in January; one that’s too large will short-cycle and handle summer humidity poorly. That’s why a technician always checks the sizing before recommending a model.

Wall-mounted heat pumps: your questions

How much does an installed wall-mounted heat pump cost in Montréal in 2026?
At HVAC MTL, wall-mounted heat pump replacement starts at $2,690 + tax, with a 10-year warranty included. The final price depends on the model, the capacity and the installation setup; you get your personalized price within 24 hours, and the LogisVert rebate can then lower the bill.
Does a wall-mounted heat pump heat at −30 °C?
Several of our wall-mounted series keep heating down to −30 °C according to the manufacturers: Gree Crossover and Vireo, Ouellet Pacific, Stelpro Pro B and Elios EMC. The Gree Livo and Vita, Ouellet Harmony, Stelpro Elite B and Moovair Mistral series run down to −25 °C. In deep cold, output drops, so we advise you on the backup heat to keep.
Can a wall-mounted heat pump heat the whole house?
A single wall unit efficiently heats the area it blows into, especially an open space. For closed rooms or several floors, we usually combine several units or a multi-zone heat pump, keeping baseboards or the furnace as backup. We suggest the simplest setup for your layout.
Can you install a wall-mounted heat pump in a condo?
Yes, it’s a common installation in condos. You usually need the board’s approval for the outdoor unit location and the wall opening. We provide the technical information requested and coordinate the work with the property manager.
Which brand of wall-mounted heat pump should I choose?
All our brands are safe choices for the Quebec climate. The choice mostly comes down to minimum operating temperature, WiFi, labour warranty and budget: the comparison table above summarizes every series. A technician recommends the best-suited model during your quote.
