By the Numbers: How Much Can You Save with a Multizone Heat Pump in Montréal?

A Smart Solution to Maximize Comfort and Reduce Your Energy Bills in Montréal

At AirGreen, we regularly install multizone heat pumps in homes and businesses across Montréal, Laval, Longueuil, the North Shore, and the South Shore. Thanks to their advanced technology, exceptional energy efficiency, and installation flexibility, these systems are a strategic choice for any property seeking personalized thermal comfort while achieving substantial long-term savings. This article presents, backed by numbers, what you can really save by opting for a multizone heat pump, with real-life examples drawn from our on-site experience.

Why Choose a Multizone Heat Pump?

Multizone systems connect several indoor wall-mounted or ceiling units to a single outdoor compressor. Each indoor unit serves a specific area of the house, with its own temperature control. This flexibility brings major advantages:

• Optimized energy consumption

• Personalized comfort based on each occupant’s preference

• Significant reductions in heating and cooling costs

• Less energy loss compared to traditional central systems

Case Study: A Multizone Installation in Rosemont–La Petite-Patrie, Montréal

A couple who owned a duplex in Rosemont reached out to us looking for a complete energy-efficient solution. Their home, typical of the area, had two floors plus a finished basement. They wanted a centralized solution without having to renovate their entire duct system. We recommended a Gree Multizone heat pump with three indoor wall units: Lomo 18,000 + 9,000 + 9,000 BTU, connected to a Gree Multi36HP230V1AO outdoor unit.

Performance Data:

• SEER: 21.5

• HSPF: 10.5

• Outdoor noise level: 56 dB

• Eligible for a $2,874 (at the rate then in effect) LogisVert grant

Before installation: Estimated annual energy bill of $2,750 (electric baseboard heating + portable AC units)
After installation: Annual bill reduced to approx. $1,375

Estimated annual savings: $1,375
Payback period: approx. 4 to 5 years, grant deducted

Comparative Analysis: Multizone Heat Pump vs. Traditional Systems

A High-Value Investment in Montréal

Montréal’s climate—with its harsh winters and increasingly hot summers—makes heating and cooling systems essential. A high-performance multizone heat pump efficiently handles these climate variations while drastically reducing electricity-related expenses.

Moreover, the multizone systems we install, including models from brands like Fujitsu, Gree, Bosch, Haxxair, and Mitsubishi, are known for their reliability, quiet operation, and long service life.

What Our Clients Are Saying

The Gagnon Family, Villeray–Saint-Michel–Parc-Extension:

“We called AirGreen to replace our old electric baseboards with a Gree multizone heat pump with four indoor units. The comfort is unmatched, especially at night. But what really surprised us was our first Hydro bill: 40% less!”

Ms. Tremblay, Longueuil (rental duplex):

“I chose a multizone heat pump for both floors of my building. With the grants and the savings, the system will be paid off in 3 years. My tenants are thrilled.”

Available Grants: A Resource Not to Overlook

Multizone heat pumps are eligible for several grants in Québec:

• Hydro-Québec’s LogisVert program: $120 per 1,000 BTU/h at -8 °C for an ENERGY STAR cold-climate model

• Federal “Greener Homes” program: closed; a new federal heat pump program was announced on October 8, 2026 (rules to come)

• Additional municipal subsidies in some areas

At AirGreen, we help you maximize your grants by assisting with administrative steps from the start of your project.

Common Mistakes to Avoid When Purchasing a Multizone Heat Pump
