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.

Installation Details and Process
This installation in Montreal was meticulously executed by our team, ensuring optimal placement and secure mounting to maximize both efficiency and longevity. The outdoor unit, measuring 33.47 x 13 x 27.94 inches, is designed for durability in various weather conditions, while the indoor unit provides unobtrusive comfort with dimensions of 41.42 x 9.80 x 12.44 inches.
The installation process included:
- Site Assessment – Evaluating the ideal location for both interior and exterior units to ensure efficient air distribution and ease of access for maintenance.
- Mounting and Positioning – Secure mounting for the outdoor unit to withstand Montreal’s weather variations.
- Piping and Wiring – Using high-quality pipes (1/4 - 3/8) and ensuring proper insulation and secure connections.
- Testing and Calibration – Fine-tuning the settings for maximum efficiency and minimal noise, with sound pressure levels kept at 53 dB(A) outdoors and 25-49 dB(A) indoors.
Plasmacluster Technology: Clean Air, Pure Comfort
SHARP’s Plasmacluster Technology is more than just an air filter. It actively purifies the air by releasing ions that neutralize airborne bacteria, viruses, and odors, ensuring that the indoor environment is as fresh as it is comfortable. This feature is particularly beneficial for urban environments like Montreal, where indoor air quality can often be compromised.
Benefits of Plasmacluster Technology
- Eliminates airborne bacteria and viruses: Promoting a healthier home environment
- Removes odors: Ideal for eliminating persistent smells from cooking, pets, or tobacco
- Reduces mold growth: Helps maintain cleaner indoor air quality
Energy Efficiency and Environmental Responsibility
The SHARP ZU1 Heat Pump uses the R-32 refrigerant, known for its low environmental impact compared to traditional refrigerants. This installation aligns with our commitment to sustainability, as R-32 reduces the greenhouse effect, helping homeowners lower their carbon footprint.
Additionally, with a 22.0 SEER rating, this mini split heat pump is designed to keep energy bills low. This efficiency makes it eligible for a substantial Hydro-Québec LogisVert Grant, offering up to $2,688 – the highest available in the 18,000 BTU category, helping to offset installation costs for our customers.

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.
