Installation of a Goodman wall-mounted heat pump in Ahuntsic-Cartierville
Installation of a Goodman wall-mounted heat pump in Ahuntsic-Cartierville. AirGreen optimizes comfort, performance, and energy savings in 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.

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 optimized installation for a Montreal condo
At AirGreen , we understand that every HVAC installation project is unique. In Montreal's Ahuntsic-Cartierville neighborhood, we recently installed a Goodman wall-mounted heat pump for a condo owner looking to combine comfort and energy efficiency in their condo. Choosing reliable equipment, combined with careful installation, helps meet heating and cooling needs year-round.
Why the Goodman brand for this project?
The Goodman brand is recognized in the HVAC industry for its excellent value, reliability, and parts availability across North America. For this condo, the client wanted a simple, robust, and high-performance solution capable of effectively managing the temperature fluctuations of Montreal's climate. The Goodman wall-mounted heat pump perfectly meets this need, offering good energy efficiency and a long service life.
Context and specific features of the project
The installation was carried out on a condo balcony , a limited space requiring careful planning. Several technical challenges were encountered:
-
Raised metal stand : To prevent snow and ice build-up during winter, the outdoor unit has been installed on a solid and stable platform.
-
Wiring and pipe routing : the refrigerant and electrical connections have been discreetly integrated using white capping, guaranteeing both protection and aesthetics.
-
Proximity to the electrical panel : a short and secure connection made it possible to optimize the reliability of the system while minimizing losses.
-
Drainage management : the raised positioning of the device facilitated efficient gravity drainage, thus avoiding the need for a condensate pump.
Key steps of installation
-
Analysis of site constraints : taking into account limited space and co-ownership rules.
-
Raised stand installation : securely attached to absorb vibrations and withstand weather conditions.
-
Drilling and line routing : precisely executed to ensure watertightness and durability.
-
Electrical and refrigeration connections : comply with the standards in force in Quebec.
-
Testing and commissioning : checking pressures, tightness and proper functioning of the entire system.
Customer Benefits
Thanks to this installation, the customer benefits from:
-
Four-season comfort (heating in winter, air conditioning in summer).
-
Reduced energy costs compared to traditional electric heating.
-
A discreet and aesthetic system, perfectly integrated into your condo.
-
Peace of mind offered by a professional installation that complies with RBQ standards.
Possible grants and savings
Wall-mounted heat pumps like Goodman's may be eligible for certain provincial and federal subsidies, including those under the Greater Montreal Energy Transition Program. These incentives help lower the initial cost and increase the return on investment.

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.
