Installation of a Sharp Eco Inverter wall-mounted heat pump in Rosemont–La Petite-Patrie
Installation of a Sharp Eco Inverter wall-mounted heat pump in Rosemont–La Petite-Patrie by AirGreen. Energy efficiency, four-season comfort, and optimized air quality.
Take a tour of the installation
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.
An elegant and efficient HVAC solution for a Montreal duplex
At AirGreen , every wall-mounted heat pump installation is unique. This project in Rosemont–La Petite-Patrie perfectly illustrates how our HVAC installation expertise seamlessly integrates modern technology into the classic architecture of the area's typical red brick duplexes.
Our client wanted to replace their old electric heating system with a more efficient and economical solution, while still enjoying the comfort of air conditioning during the summer. We therefore proposed a Sharp Eco Inverter wall-mounted heat pump , renowned for its stable performance at low temperatures and its reliability in the Montreal climate.
The advantages of the Sharp Eco Inverter heat pump
The Sharp Eco Inverter range stands out for its PlasmaCluster technology , which improves indoor air quality by neutralizing dust and allergens, in addition to regulating the temperature.
-
Adapted capacity : a device calibrated according to the dimensions of the living space, ensuring comfort without overconsumption.
-
Energy efficiency : Inverter technology that modulates power and reduces electricity consumption.
-
Quiet operation : ideal for a dense urban installation like Rosemont.
-
Grant eligibility : eligible for government programs promoting high-performance heat pumps in Greater Montreal.
Technical details of the installation
The installation required several key steps to meet standards and ensure optimal performance:
-
Outdoor positioning : The Sharp condenser has been fixed on sturdy metal wall brackets , raised to prevent any accumulation of water or snow.
-
Integration into the building : the refrigeration duct was carefully sheathed and covered to harmonize with the brick facade.
-
Electrical connection : a junction box has been discreetly installed nearby, connected to the interior electrical panel by a dedicated line.
-
Condensate management : gravity installation, allowing drainage water to drain naturally, thus avoiding the use of an additional pump.
-
Working in tight spaces : The proximity of a wooden balcony required meticulous planning to ensure accessibility and safety without compromising aesthetics.
Results and benefits for the client
Upon commissioning, the customer noted:
-
Immediate comfort , with a stable and pleasant temperature in all rooms served.
-
An anticipated reduction in your electricity bill , thanks to the efficiency of the Inverter system.
-
A gain in indoor air quality , brought by PlasmaCluster technology.
This installation perfectly illustrates our approach: solutions adapted to the Montreal architectural context , while maximizing energy efficiency and occupant comfort.

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.
