Bringing Comfort and Efficiency to Saint-Lambert Homes with Cutting-Edge SHARP Technology
When it comes to home comfort solutions, AirGreen proudly stands out as the trusted provider for reliable and efficient installations across Montreal, Laval, Longueuil, and beyond. This time, we had the pleasure of completing the installation of a 12,000 BTU SHARP ZHU1 wall-mounted heat pump in a beautiful home in Saint-Lambert, delivering both exceptional performance and modern convenience. Here’s a detailed look at this remarkable project.
Why Choose the SHARP ZHU1 Wall-Mounted Heat Pump?
The SHARP ZHU1 series is a top-of-the-line ductless heat pump designed to cater to the unique needs of Quebec’s extreme climate. Its ability to maintain high performance even in sub-freezing temperatures of -27°C makes it a standout choice for homeowners in the region. Here are some of the key highlights of the ZHU1 model:
- Heating Capacity: Handles harsh winters with ease, operating efficiently at temperatures as low as -27°C.
- Cooling Capacity: Offers a cooling output of 12,000 BTU, perfect for keeping your home comfortable during hot summers.
- Energy Efficiency: Achieves an outstanding 25.0 SEER rating, ensuring reduced energy consumption and lower utility bills.
- Silent Operation: With sound levels as low as 22 dB(A) indoors, this model is quieter than a whisper.
- Advanced Air Purification: Equipped with SHARP’s patented Plasmacluster technology, the ZHU1 neutralizes bacteria, allergens, and odors for cleaner, healthier air.
- Environmentally Friendly: Utilizes the R-32 refrigerant, which significantly reduces greenhouse gas emissions compared to older refrigerants.
The Installation Process in Saint-Lambert
At AirGreen, we believe every installation tells a story. For this particular project in Saint-Lambert, the homeowners were seeking an energy-efficient, eco-friendly heating and cooling solution to replace their aging system. After assessing their needs, we recommended the SHARP ZHU1 heat pump for its reliability, performance, and eligibility for substantial rebates.
Step 1: Consultation and Planning
We started with a comprehensive consultation to understand the layout of the home and determine the optimal location for the indoor and outdoor units. This step ensured maximum efficiency and airflow, minimizing any potential energy loss.
Step 2: Preparing the Site
The outdoor unit required a custom mounting bracket to elevate it off the ground, protecting it from snow accumulation during Quebec’s snowy winters. The brackets were securely anchored and designed to absorb vibrations, ensuring silent operation.
Step 3: Seamless Installation
Our expert technicians installed the indoor unit strategically to maximize airflow across the living area. The compact design of the indoor unit (measuring just 41.42 x 9.80 x 12.44 inches) allowed for a sleek, unobtrusive setup that blends seamlessly with the home’s interior.
Step 4: Testing and Optimization
Once the installation was complete, we tested the system thoroughly to ensure everything functioned perfectly. The homeowners were particularly impressed by the Wi-Fi connectivity, which allows them to control the heat pump remotely via their smartphone app.
Unlocking Savings with the LogisVert Grant
One of the most exciting aspects of this installation is the eligibility for the $2,268 LogisVert Grant from Hydro-Québec. This is the highest rebate available for any 12,000 BTU heat pump under the program, making it a cost-effective choice for the homeowner. By upgrading to the SHARP ZHU1, they’re not only investing in comfort but also reaping significant financial benefits.
Key Features of the SHARP ZHU1 Heat Pump
Plasmacluster Technology: Superior Air Purification
Unlike standard heat pumps, the ZHU1 features Plasmacluster technology, which replicates natural air purification processes. It eliminates up to 99% of airborne viruses and bacteria, removes mold, and neutralizes odors. This is a game-changer for families with allergies or sensitivities to indoor air pollutants.
COANDA Airflow Control: Enhanced Comfort
The COANDA airflow technology ensures uniform temperature distribution by directing airflow along walls and ceilings. This prevents uncomfortable drafts and ensures every corner of the room is evenly heated or cooled.
Energy Star Cold Climate Certification
The ZHU1 is certified by Energy Star for exceptional performance in cold climates, maintaining its efficiency even during the harshest winters in Saint-Lambert and the greater Montreal area.

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.
