Fujitsu vs Gree: central heat pump showdown – which is best suited for Montréal’s climate?

Two central heat pump giants face off: understanding the differences, advantages, and choosing the best solution for your home in Montréal

When it comes time to choose a central heat pump for a home located in Montréal, Laval, Longueuil, or elsewhere on the North Shore or South Shore, two brands frequently come up in our clients’ conversations: Fujitsu and Gree. At AirGreen, we’ve installed, repaired, and serviced both systems in all kinds of real-world conditions—from single-family homes to duplexes to rental buildings. Drawing from this hands-on experience, we’re offering you here an in-depth analysis, rooted in reality and built on what we’ve seen in the field.

Why compare Fujitsu and Gree for your central heat pump?

Both brands offer solid, energy-efficient, high-performing products—but each has its strengths depending on your comfort needs, your building, your energy usage habits, and the unique climate in Greater Montréal. The goal here is to help you make an informed decision.

Technical overview of Fujitsu and Gree central heat pump lines

Fujitsu central heat pumps: Japanese precision and efficiency

Fujitsu central systems are known for their reliability, quiet operation, and efficiency in tough climates. The model we most often install, the Fujitsu KZAH R-32, stands out for:

• Advanced inverter technology that adjusts power based on real-time demand.

• Use of R-32 refrigerant, which is more eco-friendly than R-410A and delivers better energy performance.

• BTU capacity up to 60,000 BTUs, ideal for large homes.

• Seasonal energy efficiency ratios (SEER) often exceeding 18, and heating HSPF ratings above 10, making them eligible for multiple grants, including the LogisVert program by Hydro-Québec.

Gree central heat pumps: Chinese versatility with high performance

In recent years, Gree has become a solid and affordable option for Quebec homes, with lines like Flexx or Ultra Heat. We often install the Gree Ultra Heat model in Laval and on the South Shore thanks to features such as:

• Ability to maintain steady heating power even at -30°C, which is a big plus in winter.

• BTU range similar to Fujitsu, suitable for both bungalows and large duplexes.

• Well-protected electronic components to resist humidity—very useful in areas near the river.

• Generally more affordable than Fujitsu while still delivering comparable performance.

Real-life case studies: AirGreen installations in the field

Project 1: Century-old renovated home in Villeray – Fujitsu central heat pump

A couple of professionals hired us to modernize their heating system in a century-old home that had been brought up to insulation standards. They chose a 36,000 BTU Fujitsu KZAH R-32, as the existing ductwork allowed for optimal and quiet distribution.

Challenge: Tight space for the indoor unit and uneven roofline for the outdoor one.
Solution: Custom elevated structure with anti-vibration mounts, flexible ducts, and acoustic insulation.
Result: Outstanding performance even during the -27°C cold snap in January, with energy bills reduced by 35%.

Project 2: Rental duplex in Longueuil – Gree central heat pump

For a landlord wanting to reduce energy costs and increase property value, we recommended a 48,000 BTU Gree Ultra Heat, perfectly suited for a two-zone layout.

Challenge: Avoid major disruption for tenants during installation.
Solution: Planned over two consecutive days with a dedicated team for rapid intervention.
Result: Consistent comfort for tenants, $2,300 LogisVert subsidy obtained, and perceived value of the unit increased.

The importance of proper installation in Greater Montréal

Choosing the best central heat pump is only part of the equation—quality CVAC installation is critical to ensure peak performance and long-term reliability. At AirGreen, we’ve fine-tuned our process with:

• Certified technicians trained by brand.

• A thorough pre-installation assessment based on your home’s heat load.

• Customized installations, even in complex spaces like older homes or modern condos.

Practical advice before choosing between Fujitsu and Gree

• Always request a heat load calculation before making a purchase.

• Check if your existing ductwork is compatible.

• Compare manufacturer warranties carefully.

• Analyze your long-term energy budget, not just the upfront cost.

• Ask for client testimonials or virtual walkthroughs of recent installs.

Final thoughts: Fujitsu or Gree – both are excellent for Montréal, depending on your priorities

If you’re looking for top-tier technology, ultra-quiet operation, and maximum energy efficiency, Fujitsu is a proven premium choice across our Montréal and Laval projects.
If you’re aiming for performance at a more accessible cost, with strong cold-weather reliability and fast installation, Gree offers excellent value, especially on the South Shore and North Shore.
