A tailored solution for every space in Montréal, Laval, Longueuil, North Shore and South Shore
At AirGreen, we understand that every building is unique—whether it’s a modern condo in the heart of Montréal, a family duplex in Laval, or a busy business on the South Shore. That’s why we offer customized HVAC solutions, including the multizone heat pump, perfectly suited for a wide variety of spaces. Thanks to our hands-on experience and precise approach, we design systems that maximize comfort, energy efficiency, and peace of mind for occupants, while also respecting the constraints specific to each type of building.
What is a multizone heat pump?
A multizone heat pump is a heating and cooling system that allows multiple indoor units to be connected to a single outdoor unit. This type of system is ideal for buildings with multiple rooms or floors, where each space has different needs. Every zone can be individually controlled, offering an unmatched level of comfort while enabling significant energy savings.
Why choose a multizone heat pump for a condo?
Urban condos often feature open spaces, large windows, or high ceilings—all of which create challenges in maintaining even temperature distribution. Installing a wall-mounted or discreetly built-in multizone heat pump makes it possible to:
-
Maintain a consistent temperature in key areas like the living room, kitchen, and bedroom.
-
Reduce noise thanks to quiet technology.
-
Free up floor space with compact wall units.
-
Preserve the interior design with concealed ducts or sleek units.
In a recent installation in Plateau-Mont-Royal, we equipped a 1,200 sq. ft. condo with a Fujitsu KLT 24,000 BTU multizone heat pump, connected to three wall units. The client wanted stable temperatures without overheating some rooms. The result: a 35% drop in energy bills and optimal year-round comfort.
Duplex in Laval: how to manage the needs of two floors
Duplexes often have different thermal needs on each level. For example, a better-insulated ground floor will need less heating than an upper floor beneath the roof. With a multizone heat pump, each floor can have its own temperature control, without the need to install two separate systems.
We recently completed an HVAC installation in a duplex in Chomedey, Laval. The outdoor Bosch BOVA 36,000 BTU unit, using R-454B refrigerant, powers four wall-mounted units—two per floor. Using a smart thermostat, residents can schedule each zone based on their routines, ensuring energy efficiency and custom comfort.
Multizone heat pump for businesses: a strategic choice
Commercial spaces often require adaptable heating and cooling solutions tailored to different uses—offices, waiting areas, kitchens, storage zones. A multizone heat pump allows temperature control based on how each space is used and how busy it gets.
On the South Shore, we installed a Goodman multizone 48,000 BTU system in a dental clinic in Brossard. The 2,000 sq. ft. building had six rooms with varying requirements. Thanks to the six wall units, the dentists could adjust the treatment rooms (cooler temperatures) independently from the waiting area (more ambient). The energy bill dropped by 40%, and the customer experience improved significantly.
Concrete advantages of multizone heat pumps installed by AirGreen
Individual comfort
Every room becomes an independent climate zone—no more overheating one floor just to make the living room comfortable.
Reduced energy costs
Multizone heat pumps consume less energy than traditional systems, especially when paired with smart thermostats.
Flexible installation
At AirGreen, we tailor our installations to the structural constraints of every building: load-bearing walls, limited rooftop access, complex ductwork.
Grant eligibility
Our energy-efficient multizone heat pumps, such as Fujitsu R-32, Gree Extreme, or Bosch BOVA models, are eligible for Hydro-Québec’s LogisVert grants, up to $5,000 depending on the number of zones and configuration.
Installation challenges with multizone systems: what we do differently
Installing a multizone heat pump requires advanced technical expertise: refrigerant line balancing, power optimization for each indoor unit, integration into existing buildings without compromising structure.
In a project on the North Shore, in a century-old home converted into offices, we had to run piping through stone walls while maintaining the building’s heritage integrity. We used custom enclosures, concealed the units with decorative covers, and met the client’s expectations for both aesthetics and performance.
Our recommendations for choosing the right multizone heat pump
-
Evaluate the number of required zones: each indoor unit represents one independent zone.
-
Choose the right capacity (BTU): not too small, and not oversized.
-
Plan for HVAC maintenance: at AirGreen, we offer custom maintenance plans to ensure long-term performance.
-
Consult our HVAC experts: we carry out a full building analysis before every installation to deliver a personalized solution.
