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.
An elegant and efficient integration in the heart of a Laval home
At AirGreen, we recently completed the installation of a SHARP ZU1 12,000 BTU wall-mounted heat pump in a lovely Laval residence, and this project perfectly illustrates our approach: technical expertise, discreet installation, and long-lasting comfort. The unit was strategically placed in the living room, above a decorative shelf, providing optimal thermal performance while blending seamlessly with the interior decor.
Why the SHARP ZU1 series is ideal for Laval
The SHARP ZU1 12,000 BTU stands out thanks to its proven reliability in the harsh climate conditions we experience here in Québec—especially in Laval, where winters can be unforgiving. This model is designed to heat efficiently down to -27 °C, making it perfect for Québec homes seeking performance and energy savings.

An optimized installation in a compact space
For this Laval project, our team carefully assessed the living room’s wall space to install the indoor unit between a vintage wall clock and a decorative shelf. The elevated placement, near the ceiling, allowed us to maximize the distribution of warm air in winter and cool air in summer, all while preserving the aesthetic of the space. The installation was completed with a discreet conduit leading to the outdoor unit, positioned on the side of the house and protected from the elements.
SHARP’s technological advantage: Plasmacluster air purification
Unlike many standard wall-mounted heat pumps, the SHARP ZU1 model is equipped with exclusive Plasmacluster technology, which purifies the room’s air by emitting positive and negative ions that:
-
Neutralize airborne viruses and bacteria
-
Eliminate mold spores
-
Reduce allergens
-
Eliminate stubborn odors like tobacco smoke or cooking smells
This function is particularly appreciated in Laval homes where indoor air quality is essential—especially for families with children or individuals with allergies.
An installation eligible for available grants
The SHARP ZU1 12,000 BTU wall-mounted heat pump qualifies for Hydro-Québec’s LogisVert rebates, allowing homeowners to significantly reduce installation costs. We assist every client in Laval with the administrative process to help them maximize their savings.
A quick, clean, and quiet installation
Our certified technicians completed the installation in a single day, which included:
-
Wall-mounting the indoor unit with optimal spacing for ventilation
-
Precision drilling through the exterior brick with proper sealing
-
Connecting the R-32 refrigerant line with a full leak test
-
Commissioning and Wi-Fi setup for remote control access
Everything was done quietly, cleanly, and in full compliance with the industry’s highest HVAC installation standards.
Customer feedback
The homeowner, a long-time Laval resident, was looking to replace an old, inefficient, and noisy wall-mounted AC. From the very first minutes of using the SHARP ZU1, she was impressed by the silent operation and the even, consistent heating, even when outdoor temperatures were extremely low. She particularly appreciated the automatic energy-saving mode, which adjusts output once the desired temperature is reached.

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.

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.
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.

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.
