Comparison: Central Heat Pump FUJITSU vs TOSOT — Two Philosophies, Two Performances

Two leading brands, two visions of centralized heating and cooling comfort

At AirGreen, we’ve installed and maintained hundreds of central heat pumps across Montreal, Laval, Longueuil, the North Shore and South Shore, which gives us a unique perspective on the brands that dominate the Québec market. Two of these brands, FUJITSU and TOSOT, are frequently requested by our customers. While both are known for their performance and reliability, their approaches differ—whether in terms of technology, energy consumption, or overall comfort delivered to occupants.

In this article, we’ll explore the real differences between the FUJITSU central heat pump and the TOSOT central heat pump, drawing on our field experience with both systems. You’ll find examples of real installations, measurable advantages, limitations to consider, and most importantly, practical advice to help you make an informed choice based on your needs (residential, light commercial, multi-unit housing).

Brand Overview: FUJITSU and TOSOT

FUJITSU: Japanese precision in HVAC performance

Globally recognized, FUJITSU is a Japanese brand focused on continuous innovation and refined engineering. The FUJITSU central heat pump models are especially popular with our high-end residential clients in Montreal and the South Shore, thanks to their exceptionally quiet operation, modulation capabilities, and superior energy efficiency.

TOSOT: Great value from the makers of GREE

TOSOT, a brand derived from the Chinese giant GREE, offers a more budget-friendly approach without sacrificing quality. TOSOT central heat pumps stand out for their easy installation, durability, and highly competitive purchase cost. Widely used on the North Shore, they are especially appealing to owners of duplexes, triplexes, or multi-unit buildings.

Technical Comparison: FUJITSU vs TOSOT

Field Experience: Two Real Installations by AirGreen

FUJITSU in Longueuil: Ultimate comfort for a family home

Last January, our team completed the installation of a FUJITSU 36,000 BTU central heat pump in Longueuil, in a 2,400 sq. ft. single-family home. The main challenge was uneven heat distribution on the second floor—an issue common in homes built in the 1980s.

AirGreen’s solution: We installed a dual-zone central unit with smart thermostats, allowing for independent modulation on each floor. The result: a 33% reduction in electricity bills after three months, and a significant improvement in indoor comfort, especially in the bedrooms.

TOSOT in Laval: A reliable and economical solution for a duplex

In a duplex located in Chomedey (Laval), we replaced an oil furnace with a TOSOT 36,000 BTU central heat pump, paired with a compatible electric furnace.

The client wanted an affordable solution that could be installed quickly, and that would qualify for financial incentives. In less than three days, the system was up and running. Thermal comfort is now uniform across all levels, and heating costs have dropped by 45%.

Analysis: Which brand is better suited for your needs?

FUJITSU — For those who want the best

• Demanding homeowners

• Large houses

• Urban areas where noise matters

• Clients eligible for significant grants like LogisVert

FUJITSU is the ideal choice for those who want a highly efficient, ultra-quiet, and long-lasting system, equipped with advanced technology. While the initial investment is higher, it is largely offset by long-term energy savings and greater indoor comfort.

TOSOT — For a reliable and accessible solution

• Duplexes, triplexes, rental units

• Small businesses

• Buildings with tight budgets

• Clients looking for the best value for money

TOSOT stands out for projects that need a quick installation, low upfront cost, and decent efficiency. It’s a tough, proven solution for multi-unit buildings or small commercial spaces.

Grants and Energy Efficiency: A Key Factor

At AirGreen, we guide our clients through all the steps required to access available grants in Montreal, Laval, Longueuil, the North Shore and South Shore. The FUJITSU central heat pump typically qualifies for Transition Énergétique Québec or Hydro-Québec LogisVert programs, especially due to its high energy performance ratings.

The TOSOT, depending on the model, can also be eligible for financial assistance—provided it meets specific technical requirements (minimum HSPF, energy audit, etc.).

Mistakes to Avoid When Choosing Your Central Heat Pump

1. Choosing based solely on price: A cheaper model may cost you more over time if it’s less efficient.

2. Overlooking available grants: These programs can provide up to $5,000 in savings on your installation.

3. Underestimating your building’s complexity: Thermal analysis, ductwork configuration, and zoning needs should guide your decision.

4. Neglecting regular maintenance: Regardless of the brand, a poorly maintained central heat pump will lose performance quickly.
