Installation of a Zephyr wall-mounted heat pump in Sainte-Julie
AirGreen installs a Zephyr wall-mounted heat pump in Sainte-Julie: a high-performance and economical HVAC solution for optimal comfort on the South Shore of Montreal.
Take a tour of the installation
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
Optimize residential comfort with expert AirGreen installation
In a quiet neighborhood of Sainte-Julie , our AirGreen team recently installed a Zephyr wall-mounted heat pump . This type of intervention perfectly illustrates how rigorous planning, a selection of high-performance equipment and meticulous execution guarantee the comfort and energy savings sought by our customers on the South Shore of Montreal .
Why choose a Zephyr heat pump?
The Zephyr wall-mounted heat pump is increasingly establishing itself as a reliable solution adapted to Quebec's climate conditions. Designed to provide efficient heating even at low outdoor temperatures and stable cooling during humid summers, this unit is distinguished by:
-
An extended operating range (down to -25°C for some Zephyr models).
-
High energy efficiency , reducing electricity consumption.
-
A compact installation suitable for both single-family and semi-detached houses.
-
Compatibility with energy subsidy programs offered in Montreal, Laval, Longueuil, as well as across the South Shore and the North Shore.
Key steps in moving to Sainte-Julie
For this project, our team was tasked with equipping a suburban residence requiring a solution that was both efficient and discreet. Here are the highlights of the installation:
-
Strategic positioning of the outdoor condenser : the Zephyr unit was installed on a metal support anchored to the ground, under a wooden shelter already present on the site. This configuration effectively protects the unit from bad weather (rain, snow, ice) and extends its lifespan.
-
Refrigerant pipe management : the connections were discreetly routed while respecting the gravity slope required for condensate evacuation, thus avoiding the addition of a pump.
-
Ground preparation and leveling : Particular care was taken in leveling the ground, ensuring the stability of the installation and reducing vibrations.
-
Safety and aesthetics : the wiring has been sheathed and fixed neatly, ensuring both mechanical protection and a neat finish.
Challenges encountered and solutions implemented
The installation required certain adaptations specific to the context of the land:
-
Limited space under the shelter : Our team had to optimize the clearance around the condenser fan to meet the manufacturer's recommended minimum distances. Precise positioning ensured adequate air circulation.
-
Ground moisture protection : Given the unit's proximity to the garden, drainage adjustments have been made to prevent water from accumulating at the base of the compressor.
These adjustments demonstrate the importance of using experienced professionals to ensure optimal long-term operation.
Results for the client
The owner now benefits from:
-
Stable thermal comfort all year round, with a consistent temperature in all rooms.
-
Reduced electricity bills , thanks to the superior energy efficiency of the heat pump.
-
An installation that respects the aesthetic standards of the neighborhood and blends discreetly into the decor of the backyard.
-
Peace of mind comes with AirGreen's comprehensive warranty on both the device and installation.
Subsidies and profitability
This Zephyr heat pump installation makes the customer eligible for provincial and federal grant programs (LogisVert, Greener Homes, etc.), which significantly reduces the initial investment. In Sainte-Julie, as elsewhere in Greater Montreal, this financial assistance encourages the transition to more environmentally friendly and cost-effective HVAC systems.

The big day, step by step
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.

What would it look like 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.

Your own project, step by step
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.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
