Wall-Mounted Fujitsu Heat Pump: How a Family in Longueuil Cut Their Bills by 40% (Exclusive Case Study)

A strategic installation that combines energy efficiency and comfort in Longueuil

As part of our mission to make Greater Montréal homes more comfortable and energy-efficient, we recently completed a wall-mounted heat pump installation in Longueuil that perfectly illustrates our tailored approach. A family living in a typical bungalow in the Saint-Hubert neighborhood reached out to us after noticing a steady increase in their electricity bills and persistent discomfort during both the coldest and hottest months.

The goal was clear: improve indoor comfort year-round, while significantly reducing energy consumption. After a comprehensive assessment of their home, our team of experts recommended the installation of a Fujitsu KZAH R-32 18,000 BTU wall-mounted heat pump, a model known for its high performance and energy efficiency, perfectly suited to the specific needs of this Longueuil home.

Choosing the Fujitsu KZAH R-32 Heat Pump: A Smart Move

The Fujitsu KZAH R-32 is a new-generation wall-mounted heat pump, designed to meet Québec’s harsh climate demands. It uses the R-32 refrigerant, which is more eco-friendly and efficient than previous generations, while delivering exceptional performance—even in extreme cold.

Technical Advantages of the Fujitsu KZAH R-32

  • 18,000 BTU power: ideal for heating or cooling a medium-sized home.

  • High energy efficiency: up to 26.2 SEER and 13.4 HSPF.

  • Operates down to -26°C (-15°F): ensures reliable comfort even in the heart of Québec winter.

  • Inverter technology: continuously adjusts output to maximize energy savings.

  • Eligible for grants: this model qualifies for Hydro-Québec’s LogisVert rebate, which helped this family significantly reduce their upfront installation cost.

A Custom Installation Adapted to the Home

Thermal Analysis of the Home

Before installation, our team conducted a complete thermal analysis of the residence: building orientation, existing insulation, layout of the main rooms, and the volume needing heating/cooling. This step is crucial to ensure the chosen heat pump truly meets the household's needs.

Installation Process

  • Installation duration: completed in a single workday without disrupting the family’s daily life.

  • Indoor unit location: installed in the central living room, to evenly distribute air throughout adjacent rooms.

  • Outdoor unit discreetly placed: at the back of the house, shielded from prevailing winds to extend the unit’s lifespan.

  • Wiring and technical paths: cleanly concealed within walls, preserving the home’s aesthetic.

Concrete Results: A 40% Reduction in Energy Consumption

Three months after installation, the family shared their initial Hydro-Québec bills with us: over 40% lower compared to the same period the previous year. The system not only eliminated their reliance on baseboard heating, but also stabilized temperatures in all rooms, day and night.

Customer Testimonial

“Before, we froze in the bedrooms during winter and baked in summer. Now, everything is even, quiet, and we really see the difference on the bills. Thanks to AirGreen for their professionalism and attentiveness.”

LogisVert Rebate: A Valuable Boost

In this project, the LogisVert rebate offered by Hydro-Québec played a decisive role. Since the Fujitsu KZAH R-32 heat pump is a high-efficiency model, the family received a $1,704 rebate, significantly lowering the total project cost.

We always guide our clients through the rebate application process, preparing the necessary documents and walking them step by step to maximize available financial aid.
