Modern comfort and energy efficiency in the heart of Town of Mount Royal
At AirGreen , we recently installed a Sharp wall-mounted heat pump in a residence in Ville Mont-Royal , meeting the specific needs of a client looking to improve their indoor comfort while reducing their energy bills. This project perfectly illustrates our approach: combining technical expertise, judicious choice of equipment and careful installation, adapted to the architectural context of an urban home.
Choice of device: Sharp, a safe bet in HVAC
The client was looking for a reliable, quiet and efficient solution, capable of providing both heating in winter and cooling in summer . The Sharp wall-mounted heat pump was the ideal choice thanks to:
-
Its high energy efficiency (SEER and HSPF competitive for the Quebec climate).
-
Its ability to operate efficiently even on cold days, common in the Montreal area.
-
Its discreet sound , essential in a house in Ville Mont-Royal where tranquility is a priority.
Technical details of the installation
The indoor unit was securely mounted on a central wall of the home, at an optimal height to ensure even air distribution . The installation included:
-
A discreet wall opening , with a direct passage to the outside in order to limit the length of the refrigeration circuit.
-
Gravity flow condensate management, adapted to the configuration of the premises.
-
Dedicated electrical wiring , connected to the main panel, guaranteeing safety and compliance with standards.
-
A neat white capping to camouflage the refrigerant connections, in harmony with the interior aesthetics.
Challenges encountered and solutions provided
One of the main challenges was the configuration of the load-bearing wall, which required high precision drilling to maintain structural integrity. Our technicians used a laser guidance system to ensure perfect alignment, reducing the risk of infiltration and optimizing airflow efficiency.
Another challenge concerned aesthetic integration: in a Town of Mount Royal home, appearance is as important as performance. We therefore took care to minimize the visibility of exterior ducts, while respecting access constraints for future maintenance.
Immediate benefits for the customer
Upon commissioning, the client noticed a significant improvement in thermal comfort in their main living space. In addition to maintaining a consistent temperature, the Sharp heat pump reduces energy consumption, contributing to substantial annual savings.
Grant Eligibility
The installed Sharp heat pump is eligible for current provincial and federal grant programs, particularly for its energy efficiency and ability to operate at low temperatures. Our experts systematically assist our clients in preparing application files, facilitating access to this financial assistance.
Maintenance and durability
To ensure the longevity and optimal performance of the equipment, we recommended a regular HVAC maintenance plan to the client:
-
Clean the internal filters every two months.
-
Annual check of refrigerant pressures.
-
Preventive inspection before winter, to ensure uninterrupted heating even during very cold weather.

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.
