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.
In the world of residential HVAC, every installation is an opportunity for us to showcase our expertise, precision, and commitment to long-lasting comfort. This time, our AirGreen team headed to a quiet residential area in Laval to install a SHARP ZU1 12,000 BTU wall-mounted heat pump, a unit known for its cutting-edge Japanese technology, high energy efficiency, and ability to heat even during extreme cold. Let’s dive into the details of a project that combines aesthetics, performance, and innovation.
Why choose the SHARP ZU1 12000 BTU model?
The choice of the AY-XPC12ZU model from SHARP was a natural one for this client, who was looking for a compact yet powerful system capable of maintaining optimal comfort year-round without compromising the interior’s visual appeal.
Key technical benefits of the model:
-
12,000 BTU capacity, ideal for rooms between 25 to 40 m²
-
Exclusive Plasmacluster technology: purifies air, neutralizes mold, bacteria, and odors
-
Outstanding energy efficiency: SEER 22 / HSPF 11
-
Heating down to -27 °C, perfect for Laval’s cold winters
-
R-32 refrigerant: more eco-friendly with low global warming potential
-
Extremely quiet operation at 23 dB indoors, for silent comfort
This heat pump offers an excellent balance between energy efficiency, indoor comfort, air purification, and environmental responsibility.
Context and preparation of the installation in Laval
The property in question is a two-storey single-family home. The planned location for the indoor unit was on the upper floor, in a hallway leading to several bedrooms. A strategic choice to allow for a uniform air distribution across the sleeping area.
However, this configuration presented a few challenges:
-
Reduced ceiling height in the hallway
-
Optimized airflow needed to avoid direct drafts
-
Need to integrate the unit discreetly without disrupting aesthetics
Our technicians conducted a comprehensive thermal assessment, checked the insulation, and confirmed the electrical compatibility before proceeding. Once the model was confirmed, the installation was planned with attention to every architectural and technical detail.
Installation process: precision and adaptability
Indoor unit installation
The AY-XPC12ZU model is compact, with a width of 35 inches (88 cm) and a depth of 9 inches (23 cm). We installed it with millimetric precision, just above the doorway, in a discreet spot that was perfectly suited to ensure even airflow distribution.
Technical details worth noting:
-
Drilling through the load-bearing wall with a controlled drainage slope
-
Installation of a reinforced mounting plate
-
Acoustic insulation of the conduits to minimize vibrations
-
Calibrated condensate drainage to avoid backflow
Outdoor unit installation
The AE-X12ZU unit was mounted on a sturdy wall bracket at ground level, protected from the elements and with ample clearance for easy maintenance. This model includes multiple drainage holes to prevent freezing, making it perfectly suited to the cold winters of Laval.
Wi-Fi integration and setup
Like all SHARP heat pumps, this model includes built-in Wi-Fi, allowing the client to control the temperature remotely via a mobile app. We guided the homeowner through the connection process, explained the smart features (schedule programming, geolocation, energy cost tracking), and optimized the settings for lower energy consumption.
Impeccable finish and a satisfied client
At the end of the installation, our client in Laval experienced:
-
Stable and comfortable temperature throughout the upper floor
-
Quiet operation with no direct drafts
-
Active air purification, noticeable within the first few days
-
Better control over electricity usage
The installation took half a day, showcasing the efficiency of our technical team and our operational precision.

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.
