Improving comfort, optimizing energy efficiency, and adapting to Montréal’s climate reality are now top priorities for both residential homeowners and building managers. In this context, the multizone heat pump stands out not only as an alternative but as a superior solution to traditional centralized heating systems. At AirGreen, our field experience installing and maintaining these systems across Montréal, Laval, Longueuil, the North Shore and the South Shore allows us to confidently state that the multizone heat pump is the way to go for those seeking performance, flexibility, and energy savings.
A flexible solution suited to all layouts
Unlike conventional central heating systems, which distribute heat uniformly—and often inefficiently—a multizone heat pump offers independent temperature control for each zone or room in the home. This means you can adjust the temperature based on actual needs, avoiding unnecessary overheating and reducing overall energy consumption.
We recently installed a Gree Multi+ multizone heat pump with 36,000 BTU in a single-family home in Outremont, a Montréal neighborhood where properties are often older with thick walls. Thanks to this setup, our client was able to heat three distinct zones independently: the main living room, the upstairs bedrooms, and the basement office. Result: an immediate 32% reduction on their energy bill in the very first month.
Significant energy savings from day one
Modern multizone heat pumps, such as those from Fujitsu, Gree, or Bosch, use inverter compressor technology, which automatically adjusts output based on thermal needs. This allows up to 50% reduction in energy consumption compared to electric or oil heating systems.
In Longueuil, we replaced an old oil system in a triplex with a Bosch BOVA multizone heat pump, integrating four indoor wall units. Thanks to this upgrade, the property owner now benefits from Hydro-Québec’s LogisVert grant, up to $2,500, on top of a noticeable drop in operating costs.
Unmatched thermal comfort—winter and summer
Multizone heat pumps don’t just provide efficient heating in the winter: they also serve as high-performance wall-mounted air conditioners during the summer. This dual function makes them ideal for our Québec climate, marked by harsh winters and increasingly hot summers.
In Laval, a multigenerational home equipped by AirGreen with a Fujitsu KWL multizone heat pump (42,000 BTU) maintained a comfortable 21°C temperature throughout the house, even during the deep freeze in January. In the summer, that same system keeps the bedrooms cool during heat waves—no need for noisy, power-hungry portable AC units.
An energy-efficient solution supported by grant programs
The multizone heat pump is recognized by multiple government and incentive programs, including Hydro-Québec’s LogisVert, Chauffez Vert, and even some municipal subsidies. These programs help homeowners get partial reimbursement for their installation, making the system even more affordable.
In Brossard, on the South Shore, a client who installed a 36,000 BTU Haxxair multizone heat pump with four wall-mounted units received a $2,145 rebate, covering nearly 30% of the total installation cost. AirGreen handled all the paperwork, making it easy to access these financial incentives.
Clean, fast installation with no major renovations
One of the big advantages of multizone heat pumps is how easy they are to install, even in older buildings or multi-story homes. Unlike ducted central systems, indoor units are discreet, wall-mounted or recessed, and connected to a single outdoor unit via small refrigerant lines that require minimal intrusion.
At AirGreen, our team of certified technicians recently completed a full installation in a century-old duplex in Montréal’s Plateau-Mont-Royal. Without opening any walls or altering the structure, we installed three wall-mounted units connected to a single Bosch BOVA-R454B outdoor compressor. The entire project was completed in under two business days, without disrupting the client’s daily life.
A long-lasting, reliable, and quiet investment
The multizone heat pumps we install are built to last over 15 years with minimal maintenance. They’re also extremely quiet, both inside and outside, significantly improving the home’s acoustic comfort.
In Saint-Jérôme, on the North Shore, a homeowner contacted us to replace a noisy old electric system. Since installing a 30,000 BTU Zephyr multizone heat pump, indoor noise levels dropped dramatically—from 57 dB to 29 dB. This simple upgrade not only improved quality of life, but also increased the property’s resale value.
