Longueuil’s Ultimate HVAC Upgrade: Energy Efficiency Meets Cutting-Edge Technology
A Seamless Installation Experience in Longueuil
At AirGreen, we recently completed the installation of an 18,000 BTU SHARP ZU1 wall-mounted heat pump in the beautiful city of Longueuil. This system represents the perfect blend of performance, durability, and eco-friendliness, making it one of the most sought-after models in Québec. The SHARP ZU1 isn’t just another heat pump—it’s a reliable companion for your year-round comfort, designed to handle Québec's harsh winters with heating capabilities down to an impressive -27°C.
Why the SHARP ZU1 Stands Out
The SHARP ZU1 heat pump is more than just a heating and cooling solution—it’s a technological marvel. It boasts:
- 18,000 BTU Cooling Capacity: Perfect for keeping your home cool and refreshing during the summer.
- Plasmacluster Air Purification Technology: Unique to SHARP, this technology eliminates airborne viruses, bacteria, and mold, ensuring healthier indoor air.
- Energy Efficiency at 24.0 SEER: This exceptional efficiency means lower energy bills and a reduced carbon footprint.
- R-32 Refrigerant: A next-generation, environmentally friendly refrigerant that aligns with future energy standards.
Our clients in Longueuil can also take advantage of the LogisVert Grant by Hydro-Québec, receiving up to $2,640—the highest grant available for an 18,000 BTU system in Québec!
The Installation Process: Precision and Expertise
Our professional team carried out this project with meticulous attention to detail, ensuring the unit's seamless integration into the home’s exterior. The outdoor compressor, with its sleek and compact design, was mounted securely on the brick façade, complementing the home’s aesthetic. Inside, the wall-mounted unit was strategically placed for maximum airflow efficiency and even temperature distribution throughout the space.
Key technical details of the installation:
- Dimensions of the Indoor Unit: 41.42 x 9.80 x 12.44 inches
- Dimensions of the Outdoor Unit: 33.47 x 13 x 27.94 inches
- WiFi Connectivity: Allows the homeowner to control the unit remotely via smartphone.
- Sound Pressure Levels: Quiet operation with 25-49 dB(A) indoors and 52 dB(A) outdoors.
How the SHARP ZU1 Transforms Home Comfort
Winter-Proof Heating
Longueuil winters are no match for the SHARP ZU1. With its patented Hot Gas Pipe System, this heat pump prevents the outdoor compressor from freezing, ensuring uninterrupted operation even during extreme cold snaps.
Whisper-Quiet Performance
No one wants a noisy HVAC system disrupting their peace. The SHARP ZU1 offers whisper-quiet operation, making it ideal for bedrooms, living rooms, and other quiet spaces.
Enhanced Airflow with Coanda Technology
Thanks to SHARP’s Coanda airflow control, the air is distributed uniformly across the room without uncomfortable drafts. This ensures that every corner of the home remains at the perfect temperature.
Smart Features for Modern Living
Equipped with advanced WiFi connectivity, the SHARP ZU1 allows homeowners to:
- Monitor energy consumption in real-time.
- Adjust settings remotely for optimal energy savings.
- Use GPS interlocking to automate operations when leaving or returning home.
Eco-Friendly Innovation with R-32 Refrigerant
By using R-32 refrigerant, the SHARP ZU1 aligns with modern environmental standards. This refrigerant has a lower global warming potential, reducing greenhouse gas emissions and enhancing energy efficiency by up to 10% compared to traditional refrigerants.

The job tools
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.
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.
