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.
Elevating Comfort and Aesthetics with Precision Installation
At AirGreen, our commitment to providing top-tier HVAC solutions in Montreal, Laval, Longueuil, North Shore, and South Shore is exemplified by our latest project—a state-of-the-art Sharp ZU Wall-Mounted Heat Pump installation in the picturesque neighborhood of Saint-Lambert on the South Shore. This project not only showcases our technical expertise but also our dedication to delivering both functionality and aesthetic appeal in our installations.
Designing with Aesthetics in Mind
For this specific project, the homeowner’s main concern was the visual impact of the outdoor unit. Understanding the importance of maintaining the home’s exterior beauty, our skilled technicians strategized to install the Sharp ZU 18 000 BTU model in a manner that emphasized aesthetics without compromising performance. The compressor was installed at a strategic height to align with the home’s architectural elements, and special attention was paid to conceal all pipes and electrical wires with aluminum capping. The result is a seamless integration of the unit with the home’s facade, ensuring that functionality coexists with form.
The Sharp ZU Heat Pump: A Synthesis of Technology and Efficiency
The Sharp ZU model is renowned for its robust performance and cutting-edge features. This 18 000 BTU unit, capable of providing both cooling and heating efficiencies down to -27°C, is an excellent choice for the variable Canadian climate. Equipped with innovative technologies like Plasmacluster for air purification and Coanda airflow control, the unit guarantees a consistent and comfortable indoor environment.
-
Energy Efficiency: With a 24.0 SEER rating, this unit is among the most energy-efficient on the market. It’s also equipped with the latest R-32 refrigerant, which not only enhances performance but also reduces the environmental impact.
-
Plasmacluster Technology: This unique feature offers superior air purification by eliminating airborne viruses, mold, and odors, thus enhancing indoor air quality and ensuring the health and comfort of the household.
-
Coanda Airflow Technology: This function optimizes air distribution, ensuring uniform temperatures across different rooms without direct airflow that can create uncomfortable drafts.
Installation Insights: Challenges Overcome
Installing the Sharp ZU Heat Pump posed unique challenges, primarily due to the structural layout of the residence. Our team skillfully navigated these complexities by customizing the installation process to accommodate the building's specific needs. The outdoor unit required additional supports to ensure stability and durability, especially given the region's harsh weather conditions. This meticulous approach not only secured the unit but also preserved the structural integrity and aesthetic of the home.

The big day, step by step
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 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.
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.
