A careful installation for lasting comfort
At AirGreen , we recently installed a Sharp Eco Inverter wall-mounted heat pump in a residence in the Sainte-Rose area of Laval . This project perfectly illustrates our expertise in residential HVAC installation : a methodical approach, reliable equipment, and optimized results to provide comfort and energy savings to occupants.
Installation context
The client wanted to upgrade their air conditioning and heating system to improve energy efficiency while reducing operating costs. They chose the Sharp Eco Inverter heat pump , a solution renowned for its reliability, efficiency and Ion Plasmacluster technology , which also helps improve indoor air quality.
Equipment Features
-
Brand : Sharp
-
Range : Eco Inverter
-
Type : Wall-mounted heat pump (mini-split)
-
Integrated technology : Ion Plasmacluster (air purification)
-
HVAC installation eligible for grant programs for Greater Montreal, based on energy efficiency criteria.
This model is particularly suited to single-family residences on the North Shore and offers reliable performance even during harsh Quebec winters.
Steps and technical details of the installation
Preparation and choice of location
After inspection, we chose a strategic location outside , on a newly poured concrete slab. To ensure optimal stability and prevent problems related to frost or snow accumulation, the unit was fixed on a raised galvanized aluminum support . This type of support extends the life of the equipment by avoiding direct contact with the ground.
Refrigeration and electrical connections
The refrigeration lines were carefully insulated and secured to ensure maximum efficiency. The line routing was optimized to reduce pressure losses and facilitate future maintenance. The electrical connection was carried out in accordance with current standards, respecting safety distances and the manufacturer's instructions.
Condensate management
The system has been configured to provide gravity drainage of condensate, thus avoiding the need for an additional pump. This approach reduces the risk of breakdown and ensures increased reliability.
Finishing and commissioning
The whole unit was protected with discreet capping that matched the facade . After a series of rigorous tests (tightness, pressure, vacuum and refrigerant charge), commissioning confirmed the optimal operation of the heat pump. The customer immediately noticed the difference in terms of comfort and silence of the unit.
Benefits for the customer

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.
