Installation of a Sharp ZHU Wall-Mounted Heat Pump in La Petite-Patrie, Montreal
As a leading HVAC company in Montreal, AirGreen is proud to share the details of our recent installation in La Petite-Patrie. We installed a state-of-the-art Sharp ZHU Wall-Mounted Mini Split. This installation showcases our commitment to providing top-notch HVAC services across Montreal, Laval, Longueuil, North Shore, and South Shore.
The Sharp ZHU Wall-Mounted Mini Split
The Sharp ZHU is a high-efficiency, wall-mounted mini split system. It's an Energy Star® certified model, meaning it meets stringent energy efficiency guidelines set by the U.S. Environmental Protection Agency and the Department of Energy. The ZHU model also comes with WiFi capabilities, allowing homeowners to control their HVAC system remotely.
The Sharp ZHU model we installed is an 18,000 BTU unit, perfect for medium to large-sized homes. It operates at a sound pressure level of 52.0 dB(A) outside and 25 / 49 dB(A) inside, making it a quiet addition to any home. The unit uses R-32 refrigerant, known for its low environmental impact and excellent thermodynamic performance.
The Installation Process
The installation process was of medium difficulty. We installed the head unit on the second floor, right on top of the staircase. This strategic placement allows the Sharp ZHU to comfortably heat two floors at the same time. The unit's unique design and Plasmacluster ion technology also purify the air, providing a healthier indoor environment.
The customer was thrilled with the mini split's ability to push air very far, ensuring the entire home stays at a perfect temperature. The Sharp ZHU's advanced features and our expert installation resulted in a highly efficient HVAC system that delivers comfort and energy savings.
The Benefits of the Sharp ZHU Wall-Mounted Mini Split
The Sharp ZHU Wall-Mounted Mini Split offers several benefits:
- Energy Efficiency: With a SEER rating of 25.0, this unit is highly energy-efficient, which can lead to significant savings on energy bills.
- Air Purification: The Plasmacluster ion technology helps to purify the air, reducing allergens and odors.
- Comfort: The unit's ability to push air far and wide ensures consistent temperature throughout the home.
- Quiet Operation: The low sound pressure levels mean the unit operates quietly, causing minimal disturbance.
- Warranty: The unit comes with a 10-10-10 warranty (Compressor - Parts - Labor), providing peace of mind for the homeowner.
Provincial Grant and Energy Savings
The Sharp ZHU model is eligible for a provincial grant of $700, making it an affordable option for homeowners looking to upgrade their HVAC system. The unit's high energy efficiency can also lead to significant savings on energy bills, making it a smart investment for the long term.
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.
