Installation of a Goodman wall-mounted heat pump in Chomedey, Laval
AirGreen installs a Goodman wall-mounted heat pump in Chomedey, Laval, offering 4-season comfort, energy savings and professional HVAC service 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.
An efficient HVAC solution for all-season comfort
At AirGreen , we recently completed the installation of a Goodman wall-mounted heat pump in a home in the Chomedey sector of Laval . This residential neighborhood combines modern buildings and family homes where energy performance and indoor comfort are priorities. For this project, the occupants' goal was clear: to obtain a reliable, quiet, and energy-efficient solution capable of maintaining a stable temperature year-round, regardless of weather conditions.
The advantages of a Goodman wall-mounted heat pump
The wall-mounted heat pump installed in this home is ideal for medium-sized spaces, offering a power generally varying between 9,000 and 12,000 BTU . The Goodman brand, distributed for several years in Quebec, stands out for its mechanical reliability , its advantageous quality-price ratio and the simplicity of its maintenance.
Notable advantages:
-
Efficient heating in winter , even in the cold weather of Laval.
-
Efficient air conditioning in summer , with reduced energy consumption.
-
Inverter technology , adjusting compressor speed to optimize savings.
-
Quiet operation , essential in apartments or condos.
-
Eligibility for subsidies , particularly within the framework of energy efficiency programs in Quebec (LogisVert, Hydro-Québec, etc.).
Installation process by AirGreen
The indoor unit was positioned high up on a central wall, ensuring even air distribution throughout the main room. The installation was carried out with a focus on aesthetic integration, in order to preserve the unit's discretion.
Key technical steps:
-
Wall mounting with reinforced support adapted to the type of partition.
-
Discreet hole allowing passage of the refrigeration pipe and drain.
-
Gravity drainage of condensates , limiting the risk of breakdown linked to lifting pumps.
-
Secure electrical connection , connected to the panel via an independent circuit breaker.
-
Commissioning test to ensure correct pressure balance and cooling efficiency.
Challenges and solutions provided
In this project, the main constraint was the configuration of the available wall space. The AirGreen team selected a strategic location that not only ensures the device's performance, but also optimal acoustic comfort, by keeping the indoor head away from rest areas.
Immediate results for occupants
From the moment it was switched on, the occupants were able to appreciate a significant improvement in thermal comfort , without sudden temperature variations. The Goodman heat pump now allows:
-
An anticipated reduction in energy costs , especially compared to traditional electric heating.
-
Versatility of use thanks to heating, air conditioning and dehumidification modes.
-
A quiet interior atmosphere , ideal for rest and teleworking.

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.
