Sustainable Heating: Why Montrealers Are Choosing Low-Carbon Footprint Systems

Reducing Emissions While Maximizing Comfort: The Evolution of Residential Heating in Montreal and Surrounding Areas

In an urban environment where Québec winters can be harsh, residential heating is a necessity. But today, priorities have shifted. Consumers in Montreal, Laval, Longueuil, and those on the North Shore and South Shore want more than just a heating system: they want one that is energy-efficient, sustainable, and environmentally friendly. At AirGreen, we’ve noticed a clear shift in demand toward low-carbon footprint heating systems, especially with new subsidies available and the rise of R-32 and R-454B technologies.

Why Low-Carbon Footprint Systems Are Gaining Ground in Montreal

Montreal and its surrounding regions have been at the forefront of adopting energy-efficient solutions. Several key factors explain this trend:

  • Financial incentives offered by Hydro-Québec through the LogisVert program, which can reach several thousand dollars per project.

  • Growing environmental awareness: customers want to reduce their climate impact.

  • Technological advancements: new refrigerants like R-32 and R-454B deliver high performance while significantly lowering greenhouse gas emissions.

Understanding Eco-Friendly Technologies: R-32, R-454B, and Next-Gen Heat Pumps

Traditional refrigerants like R-410A have a high global warming potential (GWP). In contrast, newer models use low-GWP refrigerants, significantly lowering the environmental impact of HVAC systems. Here are a few examples of products regularly installed by AirGreen:

Wall-Mounted Heat Pump Fujitsu KZAH – R-32

  • Capacity: 9,000 to 18,000 BTU

  • Energy-efficient: SEER up to 33, a benchmark on the market

  • Quiet and discreet: ideal for single-family homes

  • Typical installation in Longueuil: replaced an older R-410A model for an immediate reduction in energy consumption

Central Heat Pump Bosch BOVA IDS Premium – R-454B

  • Power: up to 5 tons (60,000 BTU)

  • Ultra-precise inverter technology

  • Perfect replacement for old forced-air systems

  • Frequently installed in Laval in duplex homes for year-round performance

Air Handler System with Goodman R-32

  • Highly compatible with outdoor heat pumps

  • Ideal for homes with existing ductwork

  • Used in many South Shore projects, often as part of eco-energy renovations backed by subsidies

AirGreen Case Study: Full Low-Carbon System Installation in Sainte-Thérèse (North Shore)

We recently completed a full replacement in a two-story home built in the 1990s in Sainte-Thérèse. The original system, an oil furnace, emitted a significant amount of CO₂.

Our solution:

  • Complete removal of the furnace and oil tank

  • Installation of a Goodman R-32-compatible Air Handler, connected to an outdoor Bosch IDS Premium heat pump

  • Added a smart thermostat with automated programming

  • Installation time: 3 business days, including duct cleaning

Result:

  • Over 50% reduction in the annual energy bill

  • Confirmed eligibility for $4,650 in subsidies through LogisVert

  • Optimized year-round comfort, even at -25°C

Concrete Benefits for Homeowners in Montreal and Surrounding Areas

Long-Term Energy Savings

Thanks to better energy efficiency, these systems consume less, which translates into lower bills starting from the first month.

Increased Thermal Comfort

Modern systems are designed to maintain a stable, comfortable temperature—even during the coldest January days.

Subsidy Eligibility

Eligible homeowners can receive up to $5,000 in combined subsidies, depending on the technology installed and their location.

Increased Property Value

Homes equipped with eco-friendly HVAC systems attract more buyers and can justify a higher market price.

Practical Advice: Mistakes to Avoid When Choosing an Energy-Efficient System

  • Skipping a professional home energy assessment: a proper evaluation is essential for selecting the right capacity (BTU).

  • Choosing a unit that doesn’t qualify for available grants: some incentives require the use of low-GWP refrigerants.

  • Hiring an uncertified installer: this compromises not only the system’s efficiency but also your eligibility for financial assistance.
