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.

A Seamless Installation on Montreal’s Rooftop
This particular installation was conducted on a stunning residential rooftop in Montreal, where space constraints often pose unique challenges. Our team tackled the project with precision, ensuring all components were securely mounted and optimized for longevity.
The Project Details
- Exterior Unit: Compact yet robust, the 33.47 x 13 x 27.94-inch compressor (Model: AE-X3M24BU) was mounted on a specialized platform to ensure stability and performance during inclement weather.
- Interior Units: Three 9,000 BTU wall-mounted units (Models: AY-XPC9BU) were strategically placed in key areas of the home to ensure optimal airflow and temperature distribution across all zones.
- Refrigerant: The system utilizes R-32, an eco-friendly refrigerant with a reduced Global Warming Potential (GWP) and superior heat transfer capabilities.
Our technicians ensured that all components, from wiring to refrigerant lines, were meticulously installed and insulated. The rooftop setup allowed for unobstructed airflow, maximizing the system's efficiency.
Advanced Features That Redefine Home Comfort
1. Plasmacluster Technology for Cleaner Air
The SHARP BU is not just about heating and cooling—it also ensures clean and purified indoor air. Equipped with Plasmacluster technology, this system emits positive and negative ions that:
- Neutralize bacteria, viruses, mold spores, and allergens.
- Eliminate unpleasant odors like cooking, tobacco, and pet smells.
- Promote a healthier indoor environment for families, especially those with allergies or respiratory conditions.
2. Performance Down to -27°C with HOT GAS PIPE Technology
The patented HOT GAS PIPE system ensures that heating performance remains uncompromised even during the coldest winter months. This innovative feature uses residual heat from the defrosting process to prevent ice buildup on the exterior unit, maintaining efficiency and reliability.
3. Smart Connectivity with Built-In WiFi
With integrated WiFi, homeowners can easily manage their heating and cooling system using their smartphone or tablet. Whether adjusting temperatures remotely or setting schedules, the SHARP BU provides unmatched convenience for today’s tech-savvy homeowners.

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.
