When the heat becomes unbearable in Montréal and surrounding areas like Laval, Longueuil, the North Shore and the South Shore, staying comfortably cool in every room of your home becomes a top priority. At AirGreen, we offer customized solutions for multizone heat pump installations, providing optimal comfort, remarkable energy efficiency, and smart temperature control across multiple zones of your home—without the constraints of a traditional central system.
The multizone heat pump: the ideal solution for ductless homes
Unlike classic central systems that require a complete duct network, the multizone heat pump allows for cooling and heating in multiple rooms using a single outdoor unit connected to several indoor wall-mounted units. This offers a major advantage for older or renovated Montréal properties often lacking ducts, or for modern multi-level homes.
At AirGreen, we frequently recommend this configuration to clients looking for independent temperature control by room—a perfect solution for families, remote workers, or homeowners wanting to control their energy bills.
Why choose a multizone heat pump instead of a classic system?
Here are some key advantages we highlight during our consultations with clients:
-
Individualized comfort: each room or zone can be controlled independently.
-
Energy savings: you avoid heating or cooling unoccupied rooms.
-
Flexible installation: ideal for ductless homes or with extensions like garages, basements, or sunrooms.
-
Discreet aesthetics: the indoor wall units are compact and elegant, fitting well into all interior styles.
Case study: a successful installation in Rosemont – La Petite-Patrie
One of our recent projects in the Rosemont – La Petite-Patrie borough of Montréal perfectly illustrates the benefits of the multizone heat pump. The owner of a century-old triplex wanted to offer optimal comfort to tenants while reducing annual energy costs.
We installed a Gree Multi+ Ultra outdoor unit, compatible with up to five wall-mounted units. Each apartment received two indoor units strategically placed in the living spaces and bedrooms. Thanks to Inverter technology and an energy efficiency SEER of 21, the system delivers outstanding performance even during extreme heatwaves.
The main challenge? Adapting the installation to the building’s structural constraints without damaging the heritage brickwork. Our certified technicians used specialized anti-vibration brackets and discreet piping to preserve the building’s exterior aesthetics. The result: a clean, quiet installation—and a satisfied property owner who qualified for the Hydro-Québec LogisVert grant, covering over $1,700 of the project cost.
Key technical details to consider
When considering a multizone heat pump in Montréal, several technical aspects must be evaluated:
-
BTU capacity: must be calculated based on the size and insulation of each room.
-
Unit compatibility: some models like the Fujitsu Airstage KX or Gree Multi+ Ultra allow for mixing different sizes of wall units for personalized comfort.
-
Energy efficiency: choose ENERGY STAR certified systems or ones with a SEER above 18 to maximize savings.
-
Grants: several government programs are available, including Hydro-Québec’s LogisVert and federal incentives for energy transition.
Our technical advisors always carry out a personalized energy assessment, free and with no obligation, to recommend the best solution for your situation.
