A silent revolution in home comfort across Montréal, Laval, Longueuil, North Shore, and South Shore
At AirGreen, we see every day how comfort needs are evolving in homes and buildings throughout Montréal and its surrounding areas. Homeowners no longer just want effective heating or cooling systems — they’re looking for smart, flexible, and energy-efficient solutions that can adapt to diverse spaces and lifestyles. That’s exactly where the multizone heat pump stands out as an essential alternative.
This advanced heating and cooling system allows multiple indoor units to be connected to a single outdoor unit, offering tailor-made comfort room by room, all while maximizing energy savings. But how does it really work? And more importantly, why does it represent a major shift in the field of residential and commercial HVAC?
What is a multizone heat pump?
A multizone heat pump is an HVAC system that serves several distinct areas of a building from a single outdoor compressor. Unlike a standard single-zone wall-mounted heat pump, it can support two to eight indoor units or more, depending on the chosen model. These units can be wall-mounted, ceiling cassette, floor-mounted, or even ducted, offering unparalleled flexibility in interior design and performance optimization.
How it works: technology serving efficiency
Multizone heat pumps operate on the same principle as a reversed refrigerator, using a refrigeration cycle to capture heat from the outside in winter and bring it indoors — or the reverse in summer. With Inverter technology and modulating compressors, these systems automatically adjust their operating speed based on the demand of each zone. This means:
-
Fewer temperature fluctuations
-
Significant reduction in energy consumption
-
Less noise, more comfort
Real advantages for homes in Montréal and surrounding areas
1. Individual comfort in every room
In Montréal, it’s common to find older buildings with very diverse room layouts. A multizone heat pump allows you to independently control the temperature in each room or floor, eliminating overly hot or cold areas. Kids can sleep in a cooler room while parents enjoy a cozier living room.
2. Reduced energy bills
By heating or cooling only occupied rooms, multizone systems allow up to 30% energy savings compared to traditional central systems.
3. Eligibility for grants
High-efficiency multizone heat pumps (like models from Fujitsu, Gree, Bosch, Sharp, or Daikin) installed by AirGreen are often eligible for Hydro-Québec’s LogisVert grants, as well as the Chauffez Vert program. This significantly reduces installation costs.
Case study: a multizone installation by AirGreen in Ahuntsic-Cartierville
One of our recent projects in Ahuntsic-Cartierville, Montréal, perfectly illustrates the benefits of this type of system. The client, owner of a duplex with a semi-finished basement, wanted to upgrade their electric heating system while optimizing temperature control in:
-
The open-concept living and dining room
-
Two bedrooms upstairs
-
A home office in the basement
We installed a Gree Free Match multizone heat pump with a 36,000 BTU outdoor unit, connected to four 9,000 BTU wall-mounted indoor units. The entire job was completed in two days, despite technical challenges running conduits through brick walls. Thanks to our expertise, we used a routing system that avoided aggressive chiseling, preserving interior walls.
Result: the client now enjoys individually controlled comfort in every room, Wi-Fi control, and a 40% drop in energy bills within the first few months.

Practical tips before choosing a multizone heat pump
-
Plan based on how rooms are used: there’s no need for an indoor head in a closet or rarely used room.
-
Ensure the outdoor unit is properly sized: incorrect sizing leads to higher energy use.
-
Think about interior aesthetics: modern wall-mounted units blend in well, but recessed units may be better for certain renovation projects.
