Family comfort and energy performance: the perfect match by LENNOX
In Montréal, where winters are harsh and summers increasingly hot, large families are looking for reliable, powerful, and durable heating and cooling solutions. This is exactly the context in which a central LENNOX heat pump becomes a smart choice, perfectly suited to the needs of bigger households.
At AirGreen, we recently carried out a complete installation of a central LENNOX heat pump in a two-storey bungalow located in the Rosemont–La Petite-Patrie neighborhood. This family of six needed an energy-efficient solution capable of maintaining consistent comfort throughout the home, while also benefiting from the LogisVert grants offered in Montréal.
A HVAC solution designed for large families
A centralized system for balanced comfort
Large families have specific needs: multiple bedrooms, spacious common areas, several bathrooms, and sometimes even a finished basement. In this case, a wall-mounted or ceiling cassette unit just doesn’t cut it. The central LENNOX heat pump, on the other hand, stands out as an ideal all-in-one solution.
The model selected was the LENNOX EL18XPV, an inverter system with a variable-speed compressor, paired with an electric furnace CBX25UH. This combo allows the heating and cooling output to be adjusted based on the home’s actual needs, which reduces energy consumption while maximizing comfort.

Thermal evaluation and personalized recommendations
First and foremost, our team conducted a comprehensive thermal assessment of the home. We evaluated the needs of each zone, measured heat loss, and checked the existing insulation. This step is crucial to avoid oversizing or undersizing the unit—two common mistakes that can be costly in the long run.
