A well-thought-out installation in a vibrant residential area of Laval
At AirGreen, we recently completed a wall-mounted SHARP ZU1 18,000 BTU heat pump installation in the Pont-Viau neighborhood, a sought-after area of Laval located along the Rivière des Prairies. This project is part of our commitment to offering energy-efficient heating and cooling solutions to families across the North Shore, backed by proximity service, deep technical expertise, and a focus on detail.
A residential project with specific technical constraints
In this red-brick home, our client wanted to replace an outdated electric heating system with a more efficient wall-mounted heat pump, while preserving the aesthetics of the rear façade. The covered balcony, while providing some protection, posed a ventilation challenge for the outdoor unit.
Thanks to our know-how, we recommended and installed a SHARP ZU1 model, known for its reliability even in Quebec’s extreme weather conditions, and equipped with a more ecological and high-performing R-32 refrigerant.

This heat pump is also Wi-Fi compatible, allowing remote control via the mobile app. It comes with a 10-year warranty on parts, compressor, and labor when installed by a certified contractor like AirGreen.
Wall-mounted console bracket: strength and aesthetics
The outdoor unit was installed using a galvanized steel wall bracket, securely anchored to the exterior brick wall. This setup ensures optimal airflow clearance and makes defrosting easier in winter. It also keeps the unit off the ground, protecting it from snow buildup and debris.
Our technicians ensured a seamless integration of the cabling and refrigerant lines, routing them through a discreet, weatherproof conduit. The electrical wiring was connected to a junction box compliant with CSA standards, ensuring safety and durability.
Why choose the SHARP ZU1 for your Laval home?
Year-round optimal comfort
Thanks to its inverter technology, the SHARP ZU1 heat pump delivers constant performance, even at outdoor temperatures as low as -27°C. It adjusts power in real time to maintain a stable indoor temperature, with no fluctuations or energy spikes.
Built-in air purification
The exclusive Plasmacluster system by SHARP releases positive and negative ions that eliminate airborne viruses, bacteria, allergens, and mold. A great feature for families concerned about air quality or with pets.
An eco-friendly commitment
With its R-32 refrigerant, this heat pump is designed to reduce greenhouse gas emissions by 30% compared to units using R-410A. Its energy efficiency also helps lower annual electricity consumption.
Tangible results and a fully satisfied customer
The installation was completed in less than a day, with no disruption to the home’s occupants. The homeowner, concerned with year-round comfort, was impressed by the unit’s quiet operation and how quickly it delivered heat.
We also handled the registration of the product with current government programs to help the homeowner maximize their eligibility for available grants. This installation qualifies for the Hydro-Québec LogisVert rebate, which can reach up to $1,704, depending on the home’s energy profile.

Our tips for a successful installation
-
Choose well-ventilated locations for the outdoor unit
-
Use a raised wall bracket in snow-prone areas
-
Opt for cold-climate certified heat pumps (up to -27°C)
-
Hire a certified installer, like AirGreen, to qualify for full warranties and government grants

The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
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.
