A modern HVAC solution to improve the comfort of a Laval home
At AirGreen , we recently completed a residential installation in Chomedey, Laval , where a client was looking for a reliable solution to ensure year-round comfort. We proposed and installed a Sharp Eco Inverter wall-mounted heat pump , an ideal choice for this type of home thanks to its energy efficiency and durability in the Quebec climate.
Why the Sharp Eco Inverter?
The Sharp Eco Inverter range is distinguished by its Plasmacluster Ion technology, which improves indoor air quality while ensuring efficient heating even during cold winter periods. With a capacity varying according to the number of indoor heads and high efficiency in both heating and cooling mode, it combines comfort, energy savings and sustainability .
-
Inverter technology : power modulation to reduce electricity consumption.
-
Plasmacluster Ion : active air purification, ideal for families sensitive to allergens.
-
Eligibility for subsidies : Hydro-Québec and LogisVert programs when performance conditions are met.
-
Efficiency in cold climates : efficient heating even at -25°C.
Client context and needs
The owner of this home in Chomedey was looking for a versatile solution that could replace an aging backup system while improving air quality. His main goal: to reduce heating costs in the winter while enjoying fresh, filtered air in the summer.
After an energy assessment and inspection of the facade, we recommended the installation of a Sharp Eco Inverter heat pump , perfectly suited to his needs.
Technical details of the installation
Our certified technicians installed the unit on a raised galvanized aluminum support , which protects the outdoor unit from snow and water accumulation in winter.
Some highlights of the installation:
-
Secure mounting : The compressor has been installed on a stable and durable structure.
-
Refrigerant connection routing : short and efficient route to minimize efficiency losses.
-
Electrical wiring : direct connection to the distribution panel, in compliance with the standards of the Quebec Electrical Code.
-
Condensate drainage : gravity installation, avoiding the use of a pump, which reduces maintenance and the risk of breakdown.
-
Optimized location : The outdoor unit has been positioned to ensure good air circulation and easy access for maintenance.
Challenges encountered and solutions provided
Limited outdoor space and proximity to a window presented an installation challenge. To address this, we:
-
chose a suitable support height to free up circulation around the unit;
-
used discreet capping to protect the pipes and preserve the aesthetics of the wall;
-
ensured reinforced insulation of the ducts to maximize energy efficiency.
Results obtained
After commissioning and performance testing, the customer immediately noticed:
-
a significant reduction in interior noise compared to its old system;
-
improved ambient air quality thanks to Plasmacluster technology;
-
efficient heating capacity, promising real savings on the electricity bill .

-
cleaning filters and coils;
-

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.
