Installation of a Zephyr wall-mounted heat pump in Sainte-Dorothée, Laval
Installation of a Zephyr wall-mounted heat pump in Sainte-Dorothée, Laval, by AirGreen. Four-season comfort, high efficiency, and installation on a raised aluminum support that complies with local standards.

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.
A neat terrace installation for four-season comfort in Laval
At AirGreen , we have just completed the installation of a Zephyr wall-mounted heat pump in a modern condo in the Sainte-Dorothée sector of Laval . This project perfectly illustrates our expertise in installing high-performance HVAC equipment in residential spaces with specific technical constraints, such as balcony terraces and wood-clad walls .
A residential project requiring precision and adaptation
The client wanted an efficient heating and cooling solution , capable of providing optimal comfort in all seasons , while remaining discreet and quiet . The space available on the terrace was limited, requiring installation on a raised aluminum support to guarantee both the stability of the condenser and optimal air circulation , even in winter when the snow accumulates.
Technical details of the installation
Our team carried out the complete installation of a Zephyr wall-mounted heat pump , a model recognized for its high energy performance and reliability in Quebec winters .
Main features of the installation:
-
Machine type: wall-mounted heat pump (mini-split)
-
Brand: Zephyr
-
Location: Sainte-Dorothée, Laval
-
Support: galvanized aluminum structure, corrosion resistant
-
Connection: insulated and capped refrigerant pipe, short lateral run to the condo wall
-
Power supply: waterproof electrical box with external circuit breaker compliant with CSA standards
-

All wiring has been carefully sheathed and insulated , ensuring maximum durability and impeccable aesthetics, in accordance with AirGreen installation standards.
Performance and energy efficiency
Zephyr heat pumps are designed to provide stable performance down to -25°C , making this solution perfectly suited to the Laval climate. This model allows:
-
Significant energy savings compared to standard electric heating;
-
Reduced greenhouse gas emissions through high-efficiency refrigerant technology;
-
Quiet operation , essential in a residential condominium environment.
Harmonious integration into a residential environment
Visual integration was a priority for the client. The Zephyr outdoor unit, with its sleek white design , blends perfectly with the building's light brown horizontal wood cladding. The elevated positioning and ample spacing between the railing and the wall allow for easy maintenance and optimal ventilation.
Thanks to this configuration, the heat pump remains protected from water splashes, frost and dead leaves, while respecting the co-ownership rules relating to the discretion of exterior installations.
Grants and Eligibility
This Zephyr Energy Star heat pump is eligible for provincial grant programs , such as Chauffez vert and Rénoclimat , due to its superior energy efficiency and performance in cold climates. At AirGreen, we support our customers every step of the way, from model selection to preparing documents for financial assistance programs .

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.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

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.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
