A careful installation to optimize comfort and energy performance
In Duvernay, a residential area of Laval known for its red brick homes and quiet streets, our AirGreen team has just installed a Gree central heat pump that perfectly illustrates our meticulous approach and expertise in HVAC . The goal: to offer a homeowner a complete heating and air conditioning solution, adapted to the Quebec climate and the specific needs of their home.
Choosing the Gree central heat pump
The Gree central heat pump stands out for its robustness, high energy efficiency, and compatibility with grant programs available in Quebec. Thanks to its technology using R-32 refrigerant, it reduces the carbon footprint while maximizing indoor comfort, even during harsh winters when temperatures drop below -25°C.
Among the major advantages of this range:
-
Energy efficient with competitive SEER2 and HSPF2 ratings.
-
Quiet operation , ideal for residential areas of Laval.
-
Durability and reliability , reinforced by anti-corrosion protection on the exchanger.
-
Compatibility with smart thermostats , allowing fine management of consumption.
Context of the project in Duvernay
The house in question is a typical brick duplex for the area, with a concrete balcony overlooking the backyard. The client was looking for a solution that would replace their old, energy-intensive electric heating system while also integrating central air conditioning.
The available space and the structure of the house led to the choice of an installation on a raised support fixed to the rear balcony. This configuration allows:
-
To ensure optimal ventilation of the outdoor unit.
-
To protect equipment from accumulations of snow and rainwater.
-
To facilitate future maintenance of the machine.
Technical details of the installation
Our team has implemented a complete system including:
-
A central Gree condenser installed on a sturdy metal support, securely fixed to the balcony for perfect stability.
-
Insulated and capped refrigeration pipes along the brick wall, ensuring long-lasting and aesthetic protection.
-
Gravity drainage of condensates , made possible by the height configuration.
-
Seamless integration with the existing interior duct network, thus optimizing air distribution in all rooms.
Particular care has been taken with the electrical connection , with an upgrade of the wiring and a dedicated circuit breaker, ensuring compliance with electrical standards and optimal safety.
Challenges encountered and solutions provided
One of the challenges of this installation was the limited space and the need to minimize vibrations transmitted to the balcony structure. To address this, we used:
-
Anti-vibration silent blocks , significantly reducing sound transmission.
-
Precise adjustment of the support height to meet the manufacturer's required clearances.
These adjustments ensure smooth and quiet operation, without disturbing the owner or the neighborhood.
Final result and benefits for the customer
Thanks to this installation, the owner now benefits from:
-
Four-season comfort , with efficient air conditioning in summer and effective heating in winter.
-
A significant reduction in your electricity bill , thanks to the high energy efficiency of the heat pump.
-
Eligibility for provincial and federal subsidies , including LogisVert and Greener Homes, which reduces its initial investment.
-
A durable installation, protected against the weather and easy to maintain.
The result is a more comfortable, energy-efficient and value-added home, with a reliable and modern HVAC system.

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 ducts, the current indoor module, the electrical panel and the planned spot for the outdoor unit.
The equipment combination, capacity and price, in writing. We check whether the combination qualifies for assistance programs.
Access protected, old unit disconnected and removed when it is being replaced.
Electric furnace or air handler, with its coil, connected to the supply and return ducts.
On a level base, raised above the snow, with free space all around.
Insulated, they enter through a sealed opening and run to the indoor coil.
Dedicated circuits, accessible disconnect, a thermostat that works with the heat pump and the backup heat.
Leak test, vacuum, start-up, airflow check and a test of both modes.
Filter, thermostat, backup heat in extreme cold: what to know before winter.

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.
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.
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.
- 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.
The right pages, at the right time
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.
