A discreet and efficient residential installation by AirGreen
At AirGreen , we recently installed a GREE wall-mounted heat pump in a charming Laval home, in a typical residential area dominated by brick facades. This project perfectly illustrates our expertise in the careful integration of an HVAC (heating, ventilation and air conditioning) system that combines comfort, energy efficiency and aesthetics.
A GREE heat pump designed for the Quebec climate
The GREE wall-mounted heat pump , here from the Livo R32 range, stands out for its R-32 refrigerant technology , which is more environmentally friendly and offers superior performance even during the harsh winters of the metropolitan area. This model, compatible with extreme temperatures down to −25 °C , offers stable comfort all year round.
Main features:
-
Capacity varies depending on the model between 9,000 and 24,000 BTU .
-
Energy Star energy efficiency , eligible for provincial grant programs .
-
Quiet mode optimized for interior comfort.
-
Intelligent defrosting system for reliable winter performance.
A harmonious integration on a brick facade
The installation was carried out on the side wall of the residence , near the entrance balcony. We mounted the GREE condenser on sturdy wall brackets , allowing good air circulation and protecting the unit from accumulations of snow and debris.
The refrigerant pipes have been carefully covered in beige casing matching the facade, for a discreet visual effect. Condensate drainage is provided by gravity , taking advantage of the natural slope of the land, which avoids any risk of freezing in winter.
An installation optimized for performance and durability
Our technicians ensured:
-
Minimize the length of refrigeration lines to limit heat losses.
-
Insulate the ducts perfectly to ensure performance is maintained.
-
Check compressor balance and wall bracket level for vibration-free operation.
-
Protect the connections with a sealant against humidity and temperature variations.
Each step, from the choice of positioning to commissioning , was carried out in compliance with the strictest HVAC standards .
Year-round comfort with controlled consumption
The installed system allows the owner to benefit from efficient heating in winter and gentle air conditioning in summer , while reducing their annual energy bill . Thanks to its variable speed compressor (inverter) , the heat pump automatically adjusts its power according to actual needs, ensuring energy-efficient and quiet operation .

The job tools
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.
How the job unfolds
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 we check on a job like this one
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.
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.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
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.
The right pages, at the right time
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.
