Zephyr wall-mounted heat pump installation in Fabreville (Laval): four-season performance and custom installation
In Fabreville (Laval), AirGreen installed a Zephyr wall-mounted heat pump with an outdoor unit fixed to the wall for better winter protection. A reliable, clean, and efficient solution for year-round residential comfort.
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.
In Fabreville , a typical residential area of Laval comprised mainly of single-family homes with vinyl siding, we recently completed the installation of a Zephyr wall-mounted heat pump . This project perfectly illustrates our approach at AirGreen : a thoughtful, robust, and aesthetically pleasing installation, adapted to Quebec's climate and the specific constraints of the property.
The photo clearly highlights the Zephyr outdoor unit, securely fixed to the wall on metal brackets designed to withstand harsh winters, snow accumulation and frequent freeze-thaw cycles in Laval.
Type of system installed: wall-mounted heat pump (residential mini-split)
This is a Zephyr wall-mounted heat pump , also called a mini-split , a very popular choice in neighborhoods like Fabreville. This type of system is ideal for:
-
houses without central flues,
-
additions or finished basements,
-
improving comfort without major renovations.
The configuration includes a wall-mounted indoor unit (not visible in this photo) and a compact outdoor unit , connected by carefully protected refrigerant lines.
Brand used: Zephyr
As indicated, the installed brand is Zephyr . This brand is known for offering reliable systems well-suited to residential needs in Quebec, with:
-
good energy efficiency,
-
compatibility with heating in winter,
-
stable operation even during large temperature variations.
Since the exact model is not visible in the image, we are referring to a new generation Zephyr wall-mounted heat pump , consistent with the common residential installations we carry out at AirGreen.
Outdoor installation details: what you notice immediately
This outdoor installation in Fabreville has several important technical features:
Wall mounting on sturdy brackets
The outdoor unit is installed on galvanized wall brackets , securely anchored to the structure. This choice allows for:
-
to avoid direct contact with the snow,
-
to reduce vibrations transmitted to the ground,
-
to extend the lifespan of the equipment.
Careful management of connections and drainage
The refrigerant lines and electrical wiring are neatly organized, with a clean vertical run along the wall. This arrangement protects the components against:
-
the shocks,
-
prolonged exposure to the elements,
-
premature wear.
Condensation drainage is also designed to prevent any backflow or accumulation of water near the foundation.
Accessibility for maintenance
The chosen location allows easy access for:
-
the annual maintenance,
-
the inspections,
-
service interventions, without having to unnecessarily dismantle the equipment.
Why a Zephyr wall-mounted heat pump is an excellent choice in Laval
In an area like Fabreville, where winters are cold and summers are sometimes very hot, a properly installed wall-mounted heat pump offers a real advantage:
-
efficient heating during the intermediate cold seasons,
-
Fast and comfortable air conditioning in summer.
-
reduced reliance on electric baseboard heaters,
-
better room-by-room temperature control.
With a professional installation like this, the system can operate stably and quietly, while maintaining an excellent level of comfort.

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.
