Installation of a Zephyr heat pump in Sainte-Dorothée (Laval)
AirGreen installed a Zephyr wall-mounted heat pump in Sainte-Dorothée, Laval, ensuring comfort, energy efficiency and performance in all seasons.
In summer, the outdoor unit rejects the house's heat outside.

Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Careful installation for lasting comfort
At AirGreen , we recently installed a Zephyr heat pump in a quiet residential neighborhood in Sainte-Dorothée, Laval . This project aimed to provide our customers with a heating and cooling solution that is efficient, quiet, and energy-efficient, perfectly suited to the Quebec climate.
A Zephyr wall-mounted heat pump: reliability and energy efficiency
Zephyr wall-mounted heat pumps are renowned for their excellent value and long-lasting durability. Designed for Quebec's harsh winters and humid summers, they provide optimal comfort year-round while significantly reducing energy costs.
The model installed here, compatible with R-32 refrigerant , guarantees stable operation down to −25°C , making it an ideal solution for Laval homeowners looking to replace their old electric or forced-air heating systems.
Technical details of the installation
The Zephyr outdoor unit has been securely mounted on galvanized wall brackets , ensuring excellent stability and optimal clearance for air circulation. The installation height protects the condenser from winter snow accumulations and facilitates future maintenance.
The refrigerant lines were routed through the façade using discreet white capping , in perfect harmony with the exterior cladding of the house. All electrical wiring and condensation ducts were carefully insulated and protected, in accordance with current HVAC safety standards.
The installation also included:
-
a rear clearance compliant for maximum heat exchange efficiency;
-
an anti-vibration mount to reduce noise;
-
protected wiring to the electrical panel, with dedicated circuit breaker.
Comfort, savings and peace of mind
Thanks to this new Zephyr heat pump , the residence now benefits from:
-
a constant and pleasant interior temperature ;
-
a reduction in electricity bills ;
-
of a low-noise system ;
-
minimal maintenance and increased longevity.
In addition, this installation makes the home eligible for provincial and federal energy efficiency grant programs , such as Rénoclimat and Chauffez vert , when the technical criteria are met.
AirGreen expertise at the service of each project
Our team handled every step—from ductwork planning to system commissioning —with exemplary rigor. Prior to delivery, a comprehensive performance test was conducted to ensure the Zephyr heat pump was operating at its full potential, both in heating and cooling mode.
Each AirGreen installation follows the same level of requirement:
-
analysis of the thermal needs of the housing;
-
choice of the most suitable model (BTU, efficiency, noise);
-
careful and compliant installation;
-
clear explanations to the customer on maintenance and use.
Conclusion: A Laval home ready for all seasons
With this Zephyr heat pump installation in Sainte-Dorothée , owners now benefit from four-season comfort , reduced energy consumption , and the reliability of a modern system supported by AirGreen after-sales service.
Our mission remains the same: to offer high-performance, sustainable and local HVAC solutions across Greater Montreal , including Laval, Longueuil, the North Shore and the South Shore .
How it goes, from the first call to the end
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
