Installation of a Friedrich wall-mounted heat pump in Laval
Installation of a Friedrich wall-mounted heat pump in Laval: increased comfort, energy savings and AirGreen HVAC service recognized throughout Greater 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.
Optimizing the comfort of a single-family home with a well-designed HVAC system
At AirGreen , every wall-mounted heat pump installation project in the greater Montreal area is an opportunity to demonstrate our expertise and attention to detail. This time, we carried out an installation in a family residence located in Laval , a typical suburban area, where the owners wanted to improve both their summer comfort and their winter energy efficiency.
Equipment selection: the Friedrich wall-mounted heat pump
The client opted for a Friedrich wall-mounted heat pump , recognized for its reliability and performance adapted to North American climates.
-
Capacity: 12,000 BTU, ideal for an open-plan living room and kitchen area.
-
Energy efficiency: Energy Star certification, guaranteeing substantial electricity savings.
-
Operation in cold weather: efficiency maintained down to approximately −25°C, an essential criterion for Laval winters.
-
Eligibility for subsidies: provincial programs such as LogisVert and certain federal aid.
Site analysis and challenges encountered
The installation was carried out on a house with vinyl siding. We had to deal with:
-
A significant facade height requiring a long vertical route for the refrigeration pipes.
-
The obligation to preserve the aesthetics of the house with white capping perfectly aligned with the lines of the cladding.
-
A confined space near a metal fence, which required precise positioning of the outdoor condenser to ensure adequate ventilation.
Technical details of the installation
-
Outdoor unit: placed on a stable concrete slab, away from pedestrian traffic and protected from possible impacts.
-
Refrigerated path: more than 7 meters long, carefully covered in white to fit into the wall.
-
Condensate drainage: gravity, thus avoiding the need for a lifting pump and reducing future maintenance costs.
-
Power supply: connection to the existing panel with a dedicated circuit breaker, compliant with the standards of the Canadian Electrical Code.
Immediate benefits for occupants
Thanks to this installation, owners now benefit from:
-
Stable thermal comfort all year round , with efficient air conditioning in summer and additional heating in winter.
-
A reduction in their energy bill , compared to their old direct electric heating system.
-
Added value to their property , because a recent and energy-efficient HVAC installation represents a major asset in the Laval real estate market.

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.
