Optimize Your Home Comfort with a Multi-Zone Heat Pump: Everything Montreal Homeowners Should Know
The harsh winters and humid summers in Montreal demand flexible, efficient, and durable heating and cooling solutions. At AirGreen, we’ve noticed a growing interest in multi-zone heat pumps, which have become a go-to CVAC solution for multi-level homes, duplexes, or properties with varied comfort needs. However, before investing in a multi-zone system, it’s important to understand its specifics, benefits, and technical considerations. Here are 7 essential things every homeowner in Montreal should know before installing a multi-zone heat pump.
1. One Outdoor Unit, Multiple Indoor Comfort Zones
The main advantage of a multi-zone system is its ability to power several indoor units (or ceiling cassettes) from a single outdoor unit. This means less clutter on your facade or balcony, less outdoor noise, and a cleaner installation, especially in urban areas like Montreal, such as Plateau-Mont-Royal or Rosemont.
At AirGreen, we recently installed a multi-zone FUJITSU AIRSTAGE heat pump with 4 zones in a residence in Ville-Marie, where each floor was treated as a separate zone. The result: customized comfort in each room and increased energy efficiency.
2. Energy Savings Are Significant
In addition to their superior energy efficiency, multi-zone heat pumps allow you to reduce your electricity consumption by heating or cooling only the rooms you use. Thanks to inverter technology, these systems automatically adjust their power to maintain the desired temperature without overconsumption.
We’ve observed an average 25% reduction in electricity bills among our clients in Laval and Brossard after replacing their old oil or electric heating systems with a multi-zone GREE MULTI+ heat pump.
3. Installation Must Be Done by Certified Experts
Installing a multi-zone system is technically complex: it requires evaluating the capacity of the outdoor unit, balancing the BTUs per zone, respecting piping distances, and properly programming the indoor modules. Poor installation can lead to performance losses, premature failures, or condensation issues.
At AirGreen, our RBQ-certified teams ensure precise sizing, professional installation, and rigorous post-installation maintenance to ensure durability and optimal performance, whether you’re in Longueuil, on the South Shore, or the North Shore.
4. Each Zone Is Controlled Independently
One of the great advantages of multi-zone systems is the ability to individually adjust the temperature in each room according to the occupants' preferences. This is ideal for families where comfort needs vary or for buildings with mixed uses (like Montreal duplexes).
For example, a client in Ahuntsic wanted a stable temperature in the main living room and a cooler bedroom for sleeping. Thanks to the installation of a multi-zone HAXXAIR 36,000 BTU heat pump, we were able to meet their needs with 4 independent wall units and centralized management through an intuitive mobile app.
5. Grants Are Available and Advantageous
Most of the multi-zone heat pumps installed by AirGreen qualify for significant government subsidies, such as Hydro-Québec’s LogisVert program, which can offer up to $5,000 depending on the system configuration and the energy efficiency of the chosen model.
We routinely assist our clients in filling out subsidy applications, as we did for a family in Sainte-Julie who was able to receive $4,600 in subsidies for the installation of a multi-zone Bosch BOVA 5-zone, R-454B system.
6. Maintenance Is Essential to Preserve Performance
A multi-zone heat pump requires annual CVAC maintenance, including cleaning the filters of the indoor units, checking refrigerant pressures, and inspecting the outdoor unit. This regular upkeep prevents breakdowns, optimizes efficiency, and extends the system’s lifespan.
Our technicians travel throughout the Greater Montreal Area, including Terrebonne, Candiac, and Verdun, to carry out full maintenance on multi-zone systems. Thanks to our preventive maintenance program, our clients benefit from priority in case of breakdowns, savings on repair costs, and peace of mind throughout the year.
7. An Ideal Solution for Renovation or Expansion Projects
Multi-zone heat pumps are perfect for projects where installing ducts is not feasible or desirable. Whether you’re renovating a duplex in Outremont or adding an extension to your home in Saint-Eustache, this system offers unmatched installation flexibility.
At AirGreen, we recently completed the installation of a TOSOT multi-zone 48,000 BTU heat pump with 5 wall units in a rental property in Montreal-North, allowing each tenant to control their own temperature — a big selling point for increasing the building’s rental value.
