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.

It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.
The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.
A shut-off switch near the outdoor unit isolates it safely for service.
Sitting on the indoor module, it moves heat between the house air and the refrigerant.
Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.
Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.
It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.
It runs the heat pump and the backup heat. It must be compatible with the installed system.
A flat roof installation project in a residential area of Terrebonne
At AirGreen , we are regularly called upon to intervene in a variety of contexts, ranging from the installation of wall-mounted units in condominiums to the installation of central heat pumps on flat roofs. Recently, our team completed the installation of a Haxxair heat pump in a residential neighborhood in Terrebonne , on the North Shore of Montreal. This type of configuration requires meticulous preparation and specific adjustments, since the condenser must be positioned stably and securely on a roof.
Installation preparation and configuration
From the moment we arrived on site, our priority was to ensure the stability of the outdoor condenser . We installed the Haxxair unit on treated wooden supports , suitable for flat roofs. This method avoids any direct contact with the roof surface and ensures better weight distribution.
The presence of exposed electrical wiring and piping also required careful planning. Our team chose an optimized route for the refrigerant connections, limiting energy losses and facilitating future maintenance.
Technical features of the Haxxair heat pump
The installed Haxxair heat pump is designed to provide four-season comfort in the Quebec climate. With high energy efficiency (Energy Star) and stable performance down to -25°C , it is eligible for grant programs available in Quebec, particularly on the North Shore, Laval, Longueuil and Montreal .
Features highlighted during this installation:
-
Inverter technology for precise power adjustment.
-
High efficiency compressor for reduced power consumption.
-
Heating and air conditioning capacity suitable for single-family homes in the Terrebonne region.
Challenges encountered and solutions provided
The main challenge of this project was the installation on a flat roof , where weather conditions (wind, rain, temperature variations) can accelerate the wear of the material. To address this, we integrated:
-
Raised supports to protect the device from stagnant moisture.
-
A specific orientation of the unit to maximize air circulation.
-
Connections protected by high-density insulation, guaranteeing optimal resistance to the harsh winters of the North Shore.
Customer Benefits
Thanks to this installation, the owner now benefits from a system:
-
Efficient in heating and cooling all year round.
-
Eligible for grants that significantly reduce investment costs.
-
Easy to maintain , since the pipe route and technical access have been designed for rapid interventions.
In addition, by choosing AirGreen, the customer benefits from comprehensive support, including advice on available subsidies, commissioning by certified technicians and post-installation monitoring.
Conclusion: know-how adapted to local realities
Every central heat pump installation in Terrebonne is unique, and our experience allows us to adapt to all configurations. Whether on a flat roof, in a garage, or in a backyard, we always strive to offer a reliable, aesthetically pleasing, and durable solution. At AirGreen, we combine our technical expertise with in-depth knowledge of Greater Montreal's energy needs to ensure our customers optimal comfort, summer and winter.
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.

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.
- Check the indoor module's filter.
- Clear winter debris from the outdoor unit.
- Test cooling before the heat arrives.
- Check the filter more often in peak season.
- Keep registers and returns clear.
- Watch condensate drainage near the coil.
- Change or clean the filter.
- Test heating and backup heat before the cold.
- Book periodic maintenance.
- Clear snow around the outdoor unit.
- Store nothing in front of the indoor module.
- Note any unusual noise or smell and call us.
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. A central heat pump uses the house's ducts.
It connects to the existing ducts to heat and cool everywhere.
2. In extreme cold, electric backup heat can take over.
The indoor module (furnace or air handler) works with the heat pump and takes over in extreme cold.
3. The filter only gets changed when the unit breaks down.
A dirty filter cuts airflow. It gets checked regularly.
4. You can reuse the old unit's size without checking.
The house may have changed: insulation, windows, added rooms. Capacity is confirmed on site.
