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.
Efficient Comfort Delivered: SHARP ZHU1 Mini Split Installation in Île-Bizard
A Modern HVAC Solution for a Canadian Winter
When it comes to braving Quebec’s harsh winters and humid summers, having an efficient heating and cooling solution is essential. At AirGreen, we take pride in offering tailored solutions to ensure year-round comfort for our customers. Our recent project in Île-Bizard–Sainte-Geneviève involved installing the state-of-the-art SHARP ZHU1 12,000 BTU ductless mini-split heat pump—a machine designed to excel in extreme climates.
Meeting the Customer's Needs: The Backstory
The customer, a family living in a charming brick house, needed a reliable and energy-efficient system to tackle freezing temperatures as low as -27°C and Quebec’s summer humidity. They sought an HVAC unit that combined cutting-edge technology with cost-saving benefits. Upon evaluation, we recommended the SHARP ZHU1—a model renowned for its 25.0 SEER energy efficiency, ultra-quiet operation, and exceptional heating performance in cold climates.
What made this project even more exciting was the eligibility of this model for a $2,268 LogisVert grant from Hydro-Québec, the highest grant available for a 12,000 BTU heat pump. This grant significantly offset the installation cost, providing the customer with both comfort and savings.
Why the SHARP ZHU1 Stands Out
Key Features of the SHARP ZHU1 Heat Pump
- Energy Star Certified: Recognized for high energy efficiency, ensuring lower electricity bills.
- Wi-Fi Connectivity: Allows remote control and monitoring through the SHARP app.
- Plasmacluster Technology: Unique to SHARP, this feature purifies indoor air, neutralizing bacteria, viruses, and allergens.
- Extreme Cold Climate Performance: Capable of maintaining heating capacity down to -27°C, making it ideal for Quebec’s winters.
- Ultra-Quiet Operation: Interior unit operates at as low as 22 dB(A), ensuring peace and quiet in your home.
- Durable Build: Equipped with anti-corrosive coating and advanced inverter technology for long-term reliability.
Installation Highlights
Precision and Efficiency in Action
The installation was carried out on the exterior brick wall of the property using sturdy mounting brackets to ensure stability and durability. Our team of experts took great care in placing the unit to optimize airflow and maintain the home’s aesthetic appeal.
-
Indoor Unit Placement:
- The indoor unit, measuring a sleek 41.42 x 9.80 x 12.44 inches, was mounted in the living area for optimal air distribution.
- Its long diffuser blade ensures a balanced airflow, heating or cooling the space uniformly without uncomfortable drafts.
-
Outdoor Unit Setup:
- The compact outdoor condenser (30.72 x 10.59 x 21.25 inches) was strategically mounted above ground level to protect it from snow accumulation during winter.
- With a sound pressure level of only 49 dB(A), the outdoor unit operates quietly, ensuring no disturbance to the homeowner or neighbors.
-
Advanced Refrigerant Technology:
- The SHARP ZHU1 uses R-32 refrigerant, which is more environmentally friendly and energy-efficient than traditional options. It reduces greenhouse gas emissions while improving overall system performance.
-
Wi-Fi Configuration:
- We set up the Wi-Fi-enabled system, allowing the family to control temperature settings and monitor energy usage via their smartphone—a convenience they loved.

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.
