A rigorous winter installation for four-season comfort
At AirGreen , we know that a successful central heat pump installation relies on careful preparation, proven technical expertise, and perfect adaptation to site conditions. This is exactly what our team achieved during this installation of a CanAir heat pump in a single-family residence in Sainte-Adèle , in the heart of the Laurentians, during the height of winter.
The context: performance and reliability in the heart of winter
Our clients, owners of a charming stone house typical of the region, wanted to replace their old heating system with a modern, energy-efficient and sustainable solution. The harsh climate of Sainte-Adèle required a machine capable of providing stable heating down to -30°C , while ensuring optimal comfort in summer.
Our recommendation: a CanAir central heat pump , recognized for its energy efficiency and robustness in northern environments.
Site preparation: rigor and adaptation
The installation was carefully planned despite the challenging weather conditions. The heavy snow didn't slow our team down: we protected the work area with an insulated umbrella to prevent moisture from entering during the electrical and refrigeration connections.
The outdoor compressor was placed on a raised solid slab to prevent any accumulation of ice or meltwater, a key point for the durability of the system .
The pipes were carefully routed along the stone wall, with white protective capping ensuring both aesthetics and protection against the elements . The refrigeration connections were carried out to the highest standards, then checked using a pressure manifold to ensure the circuit was perfectly sealed.

Even in the snow, our team demonstrated the rigor and passion that AirGreen is known for throughout Greater Montreal and the Laurentians.

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.

- 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.
