A reliable and elegant HVAC solution to face the North Shore winters
At AirGreen , we recently installed a Sharp Eco Inverter wall-mounted heat pump in a single-family residence located in Sainte-Thérèse , on the North Shore of Montreal . This project perfectly illustrates our expertise in residential HVAC installation in an environment where harsh winter conditions require efficient, quiet and durable systems.
A wise choice: the Sharp Eco Inverter wall-mounted heat pump
The Sharp Eco Inverter belongs to the new generation of high energy efficiency wall-mounted heat pumps , operating with R-32 refrigerant , which is more environmentally friendly and more efficient than the old R-410A.
This model, known for its Plasmacluster Ion technology , improves indoor air quality by neutralizing particles and allergens. It also ensures stable performance down to -25 °C , making it an ideal option for Sainte-Thérèse winters.
Among its advantages:
-
Quiet operation thanks to its variable speed compressor.
-
Extreme cold heating mode , optimizing interior comfort even in negative temperatures.
-
Inverter technology reducing energy consumption.
-
Plasmacluster filtration providing cleaner, healthier air.
A technical installation adapted to the Quebec climate
This installation has been carefully planned to maximize the durability and operational safety of the system in winter.
The Sharp condenser was securely mounted on galvanized wall brackets , raised to prevent obstruction by snow accumulating on the ground. The refrigerant lines and electrical wiring were routed in gray capping matching the stone facade, ensuring aesthetic integration and complete protection against the elements.
Condensate drainage is carried out by gravity , a preferred method when the configuration allows it, ensuring a smooth flow and without additional pumps. This approach reduces the risk of freezing and simplifies maintenance.
An exemplary residential construction site in Sainte-Thérèse
The AirGreen team completed the installation in a single day, despite challenging winter conditions . Thanks to our careful planning and experience in the northern climate , the project went smoothly:
-
Precise drilling through the stone wall to connect the indoor unit.
-
Reinforced insulation of refrigerant pipes to prevent any energy loss.
-
Complete check of vacuum and refrigerant level before commissioning.
-
Low temperature heating performance test to ensure optimal operation.
Why the Sharp Eco Inverter appeals to North Shore homeowners
The residences of Sainte-Thérèse, Blainville and Boisbriand share the same need: a heating and air conditioning system capable of handling significant temperature variations.
The Sharp Eco Inverter perfectly meets this challenge:
-
Significant energy savings , particularly in self-modulated heating mode.
-
Eligibility for grant programs offered by the Quebec government and Hydro-Québec for high-performance heat pumps.
-
Compact installation , suitable for townhouses or detached pavilions.
An AirGreen commitment: quality, safety and satisfaction
At AirGreen, every installation is carried out according to the highest standards in the HVAC industry :
-
Use of CSA and Energy Star certified materials .
-
Respect clearance distances for optimal airflow.
-
Careful finishing of the fittings and wall fixings.
-
Complete electrical inspection ensuring compliance with the Quebec building code.
We also ensure that our customers understand the operation and maintenance of their new system: regular cleaning of filters, winter clearing around the condenser and annual inspection by our certified technicians.
In conclusion
This Sharp Eco Inverter heat pump installation in Sainte-Thérèse demonstrates our commitment to offering reliable, aesthetic and efficient HVAC solutions, adapted to the climatic realities of Greater Montreal.
Thanks to the precision of our work and the quality of Sharp equipment, the owner now benefits from four-season comfort , controlled energy consumption and purified indoor air — a perfect combination for the Quebec lifestyle.

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.
