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.

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.
A residential project where efficiency and aesthetics meet
At AirGreen , we know that installing a wall-mounted heat pump is about more than just energy performance. It must also blend seamlessly into the building, meet the specific needs of the occupants, and ensure long-term reliability. This is exactly the approach we took when installing a Sharp Eco Inverter in a house in the Chomedey district of Laval .
Client context and needs
Our client was looking for a solution to improve the comfort of their home year-round, reducing their dependence on expensive and environmentally unfriendly traditional heating systems. The criteria were clear: a compact machine that performs well even in Quebec winters, is quiet, and is eligible for grant programs. After a detailed analysis, we recommended the Sharp Eco Inverter heat pump equipped with Plasmacluster technology, renowned for its superior air quality and energy savings.
Technical characteristics of the Sharp Eco Inverter
The Sharp Eco Inverter range is distinguished by several key elements:
-
Inverter technology for continuous power modulation and increased energy efficiency.
-
Reliable heating capacity down to -25°C , ideal for the Quebec climate.
-
Integrated Plasmacluster technology , which improves indoor air quality by reducing allergens and particles.
-
Quiet operation both indoors and outdoors.
-
A compact design allowing discreet integration into the facade.
These advantages make it a solution perfectly suited to residences in Laval , where thermal comfort and energy cost management are priorities for many households.
The steps of AirGreen installation
Preparation and strategic location
For this installation, the outdoor unit was mounted on sturdy wall brackets , slightly raised off the ground to prevent contact with snow in winter. We ensured optimal positioning, ensuring free air circulation around the fan and easy access for future maintenance.
Management of refrigeration and electrical connections
-
The connections were carefully routed via vertical white capping , providing both mechanical protection and a discreet aesthetic against the exterior cladding.
-
The electrical connection was made via a dedicated junction box, guaranteeing safety and compliance with current standards.
-
The drainage was designed in gravity mode, limiting the risks of water accumulation and avoiding the need for a condensate pump.
Challenges encountered and solutions
Installation on a wall adjacent to a concrete basement required special precision for sealing the supports. Our technicians used reinforced fasteners adapted to the nature of the wall, ensuring maximum stability. In addition, the exit angle of the connections was adjusted to avoid any mechanical stress on the insulated pipes.
Results obtained
Upon commissioning, the Sharp Eco Inverter demonstrated remarkable responsiveness: the house quickly reached the desired temperature, while maintaining minimal noise levels. The customer immediately felt an improvement in comfort, particularly thanks to the precise temperature control and ambient air quality.
Grants and financial benefits
This type of equipment is eligible for provincial and federal grant programs (LogisVert, Chauffez Vert, and other incentives). By choosing this installation, the client was able to benefit from substantial financial support, reducing the initial investment and accelerating the return on investment thanks to the energy savings generated.
AirGreen expertise in Laval and beyond
Each project is unique, and our approach is based on:
-
A personalized analysis of energy needs.

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.
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 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.
- 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.
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. 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.
