A Must-Read Introduction for Montréal Homeowners: Understanding the Essentials Before Installing a Wall-Mounted Heat Pump
In Montréal, where harsh winters alternate with increasingly hot summers, many homeowners are looking for efficient and cost-effective ways to regulate their home's temperature. Among the most popular and high-performing options, the wall-mounted heat pump stands out as an essential solution. However, while many articles cover the general benefits of these systems, few offer a comprehensive, personalized, and realistic guide based on field experience. That’s exactly what we offer here at AirGreen, thanks to our expertise in HVAC installations throughout Montréal, Laval, Longueuil, the North Shore, and the South Shore.
What exactly is a wall-mounted heat pump?
A wall-mounted heat pump is a heating and cooling system that extracts heat from the outside air (even in winter) to warm your indoor space and does the reverse in summer to keep you cool. Compact, efficient, and quiet, it's installed directly on an interior wall and connected to an outdoor unit.
This type of system is also called a mini-split or ductless unit, and it's particularly well-suited for Montréal residences, whether it’s a duplex, condo, single-family home, or rental property.
Real benefits of wall-mounted heat pumps for Montréal homeowners
✅ Adapted to Montréal's climate
Our winters are harsh, with temperatures dropping below -20°C. Fortunately, many newer models – like the Gree Extreme, Fujitsu KZAH, or Sharp ZU1 – are designed to maintain consistent performance even at -30°C.
✅ Energy savings
The built-in inverter technology in most models can reduce energy consumption by 30% to 50% compared to older electric systems or oil heating.
✅ Available grants
Thanks to programs like Hydro-Québec’s LogisVert, our clients in Montréal and both shores can qualify for grants of up to $2,172, depending on the model and installed capacity.
✅ Quick installation without major construction
Unlike central systems, a wall-mounted heat pump requires no ductwork. Installation is often completed in just one day.
Key steps to take before getting started with your installation
1. Assess your real needs
At AirGreen, we analyze square footage, insulation, home orientation, and your lifestyle habits. A condo in the Plateau won’t need the same setup as a triplex in Rosemont.
2. Choose the right capacity (BTU)
An oversized heat pump wastes energy, while an undersized model won’t effectively heat your home. We help determine the ideal output, typically between 9,000 and 24,000 BTU.
3. Consider architectural constraints
We’ve installed heat pumps in heritage buildings in Old Montréal with strict aesthetic and structural requirements. Every project is unique.
Case study: Successful installation in Outremont
A homeowner in a century-old duplex in Outremont wanted a discreet, efficient, and grant-eligible system. We installed a Gree Extreme 18,000 BTU heat pump, which qualified for a $1,704 LogisVert grant. The challenge? Fitting the outdoor unit into a tight backyard space without affecting existing greenery. The result: a satisfied client, a 40% drop in their energy bill, and year-round comfort.

Checking refrigerant levels (R-32 or R-410a, depending on the model).
