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.
A high-performance HVAC solution for optimal comfort in urban environments
In an apartment in Villeray–Saint-Michel–Parc-Extension , our AirGreen teams recently installed a Goodman wall-mounted heat pump , a brand renowned for its robustness and energy efficiency. The client wanted a compact, quiet, and economical solution, suitable for an urban home where space must be optimized without compromising on comfort.
Client context and needs
The apartment was already equipped with basic electric heating, but it didn't provide air conditioning during Montreal's increasingly hot summers. The client was looking for:
-
An all-in-one solution offering heating and air conditioning,
-
A discreet installation, integrating well into the interior space,
-
An energy-efficient system that reduces your electricity bills.
The Goodman wall-mounted heat pump met these criteria perfectly, providing both thermal comfort and energy savings.
Installation details
Inner head positioning
The wall-mounted unit was installed high up in the main room to ensure optimal air distribution. The unit sits above a decorative set of wall mirrors, demonstrating the importance of balancing aesthetics and HVAC efficiency .
Technical work carried out
-
Precise drilling of the wall for the passage of refrigeration pipes, carried out in such a way as to limit their length and reduce energy losses.
-
Use of a gravity condensate pump , allowing the natural evacuation of humidity without noise or excessive maintenance.
-
Electrical connection carried out according to the rules of the art, with protective box and compliance with RBQ standards.
Challenges encountered
The interior space was limited, with a configuration of doors and corridors requiring careful planning. Our technicians chose a strategic position that maximized air circulation while preserving the aesthetics of the home.

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.
