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.

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 clean, durable installation designed for our winters on the South Shore
In a single-family home in Boucherville , our team installed a Sharp Eco Inverter wall-mounted heat pump designed to provide four-season comfort with controlled consumption. The outdoor unit is located along a gray acrylic coated wall, in a typically residential environment on the South Shore , where compact, quiet, and reliable solutions are sought. Sharp's own Plasmacluster Ion technology enhances indoor air quality, a real plus for occupants sensitive to allergens.
Why the Sharp Eco Inverter range is a must here
Sharp's choice meets three customer requirements:
-
Energy efficiency thanks to the Inverter, which adapts power in real time and limits jolts.
-
Stable comfort in summer and winter , with fine modulation of the compressor and resistance to cold adapted to Greater Montreal.
-
Improved air quality via Plasmacluster Ion, acting on particles and odors — a differentiator compared to conventional wall units.
Without displaying the exact reference on the visible label, the Sharp Eco Inverter range belongs to the recent wall-mounted units with modern refrigerant and offers common capacities (from 9,000 to 24,000 BTU depending on the configuration). This spectrum covers the majority of living rooms and floors of houses on the South Shore .
Reading the site and preparing the worksite
The site had several characteristics that guided our HVAC installation :
-
Rendered facade with black-framed window and new cladding , requiring clean and perfectly sealed holes.
-
Open exterior space allowing ideal installation for ventilation and maintenance.
-
Electrical disconnect box already positioned nearby, ensuring a short, safe and compliant connection.
-
Bed of white draining stones on the ground: a positive point for water flow and cleanliness around the condenser.
A layout designed for winter durability
We chose a raised structure with galvanized legs/stands rather than wall brackets or a floor slab. Advantages:
-
Snow/Ice Clearance : The raised base places the unit at a safe height for air intake and prevents direct winter accumulations.
-
Stability and anti-corrosion : galvanized metal is resistant to salt and freeze/thaw cycles.
-
Easy maintenance : access under the unit remains free for inspection and seasonal cleaning.
The refrigeration path is short and direct , with a clean wall crossing ; discreet capping protects the connections while remaining minimalist to preserve the aesthetics. Condensate drainage is gravity-driven down the wall, which eliminates the use of a pump and reduces future maintenance .
Key installation steps (excerpt from our AirGreen method)
-
Thermal verification of the main room to be served and consistent BTU sizing (taking into account insulation, solar gains and occupancy habits).
-
Choice of drilling point inside (lateral clearance, absence of structural obstacle, shortest pipe path).
-
Fixing the stand with anchors adapted to the slab and millimetric leveling to limit vibrations and structural noise.
-
Brazing under nitrogen and deep vacuum , followed by a leak test and pressure control.
-
Electrical connection to the external disconnection box , circuit breaker dedicated to the panel, then commissioning with verification of blowing temperatures , currents and superheating/subcooling .
-
Finish : sealing joints at the drilling, collars and caps at the ends, drain slope confirmed.
Result: comfort, silence and careful aesthetics
As soon as it is switched on, the occupants perceive:
-
Fast air conditioning blowing , without excessive air current thanks to Inverter modulation.
-
Low noise level both outside and inside, with the unit decoupled from the ground by the stand and placed above the stone bed.
-
Clean visual integration : reduced capping, well-channeled cabling, no water trailing against the foundation.
Good practices and pitfalls to avoid (AirGreen field feedback)
-
Always raise wall-mounted condensers in snowy areas; installation directly on the ground often ends up blocked in January-February.
-
Favor short routes : beyond a certain length, the additional refrigerant charge must be calculated and recorded.
-
Avoid air discharges in front of immediate obstacles (low walls, sheds) which recycle the air and degrade performance.
-
Take care of the slope of the drain : in summer, a siphon or a counter-slope quickly results in droplets in the wrong place.
-
Check maintenance access : free space at the front and sides is essential for the longevity of the heat pump .
Recommended maintenance
To maintain performance season after season:
-
Clean the inner head filters every 4 to 8 weeks during periods of heavy use.
-
Gentle washing of the condenser exchanger (air sweep, no high-pressure jet too close to the fins).
-
Annual inspection by a technician: electrical readings, pressure, condition of insulation and capping, tightness of connections.
-
Winter clearance around the unit (drifted snow) to keep the air inlet and outlet clear.
Grants and Eligibility
Recent, high-efficiency wall-mounted heat pumps , using new-generation refrigerants and offering good cold-weather performance, are generally eligible for grant programs in Quebec. Final eligibility depends on capacity , seasonal performance , and housing configuration. Our team supports clients in Montreal, Laval, Longueuil, the North Shore, and the South Shore to validate criteria and prepare applications .

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.
