When should you install your multizone heat pump to fully benefit from subsidies in Montréal?

Optimizing the timing of your multizone heat pump installation: a strategic decision in Montréal

In today’s context where multizone heat pump subsidies are particularly generous in Montréal and surrounding areas — Laval, Longueuil, North Shore, South Shore — choosing the right moment for installation is essential. At AirGreen, we’ve guided hundreds of clients through this process, and we know that a smart HVAC installation schedule can make all the difference, both in terms of budget and comfort.

Why is the timing of the installation so important?

The timing doesn’t just impact your thermal comfort. It also determines:

  • Your eligibility for government grants, especially the LogisVert programs from Hydro-Québec.

  • The availability of multizone equipment (FUJITSU, GREE, MITSUBISHI, SHARP, etc.), often out of stock during peak seasons.

  • The speed of response from AirGreen’s technical teams.

  • The optimization of your system’s energy performance based on outdoor temperatures.

Spring: the ideal season for installation

Spring (March to May) is undoubtedly the most strategic time to install a multizone heat pump. Here’s why:

  • Grant applications are still open, and you have time to prepare your file with our team.

  • Technical teams are more available than during peak summer or early winter.

  • The equipment is installed before extreme heat hits, allowing you to immediately enjoy your multizone wall-mounted AC.

  • You’re also fully prepared for winter, with efficient high-performance heating from the first cold days.

Summer and fall: still favorable, but riskier

While installation is possible year-round, summer presents certain challenges:

  • Installation wait times increase due to high demand.

  • The most popular multizone heat pump models may be out of stock.

  • Some grants may hit their annual budget limits.

In the fall, there’s still time for installation, but beware: as winter approaches, high elevation installations become more complex, especially on condo buildings or properties with difficult access.

Winter: installation is possible but comes with constraints

We also carry out heat pump installations in winter across Montréal, Laval, Longueuil, the North Shore, and the South Shore, but this setting comes with several limitations:

  • Outdoor work is more difficult due to cold, ice, and snow.

  • Delays can be extended by winter storms.

  • Installation often requires additional equipment to temporarily heat the home during the work.

That said, some of our clients successfully took advantage of last-minute subsidies in winter, thanks to our dedicated support team for fast-tracked grant applications.

Real example: Installation of a FUJITSU multizone heat pump in Laval

Last April, we installed a 36,000 BTU FUJITSU multizone system in a single-family home in Laval. The client wanted to cover three zones: the living room, the master bedroom, and the basement. By opting for a spring installation:

  • They received a $5,000 LogisVert grant.

  • The equipment was quickly available.

  • Installation was completed in two days with no disruption to indoor comfort.

  • The heating performance in winter proved to be optimal.

Available grants and important deadlines

Currently, the main financial assistance programs include:

  • Hydro-Québec’s LogisVert: up to $5,000 depending on the number of zones and energy efficiency.

  • Chauffez Vert: can be combined with LogisVert in some cases.

  • RénoClimat: requires an energy audit before and after installation.

Note: many of these programs operate annually and may close once the allocated funds are used up. Installing early in the year gives you a better chance of receiving the financial aid.

How does AirGreen help you choose the right time?

At AirGreen, we offer:

  • A personalized analysis of your grant eligibility.

  • Recommendations on the best timing for installation based on your situation.

  • Full handling of administrative paperwork.

  • An experienced team active throughout the Greater Montréal area.

Practical tips to plan your installation

  1. Book your appointment in January or February: this gives you time to get a quote, choose the right equipment, and plan the work stress-free.

  2. Get your grant pre-approved: we help you assemble your LogisVert or RénoClimat application.

  3. Plan for delivery delays: some multizone models (e.g., Mitsubishi Zuba Multi or Fujitsu Airstage) have lead times of 4 to 6 weeks.

  4. Avoid peak seasons: June to August and November to December.

Our conclusion: anticipation is your best asset

The more you anticipate the installation of your multizone heat pump, the more you increase your chances of receiving significant subsidies, choosing the right model tailored to your home, and enjoying optimal year-round thermal comfort.
