A discreet and efficient installation, adapted to the needs of a modern home in Pierrefonds
At AirGreen, we know that every HVAC installation project requires a tailored approach, especially when optimizing the comfort of a condo while respecting its interior aesthetics. This is exactly what we achieved when installing a SHARP ZU1 12000 BTU wall-mounted heat pump in a residential apartment located in Pierrefonds, a peaceful neighborhood in the west of Montreal.
This installation perfectly illustrates our commitment to careful, quiet, and highly technological work, while ensuring exceptional energy performance, even in winter.
Choosing the SHARP ZU1 model: cutting-edge technology serving well-being
Why did we recommend the SHARP ZU1 12000 BTU?
The choice of a SHARP ZU1 wall-mounted heat pump for this condo was a natural decision thanks to several key features of the model:
-
Cooling capacity: 12,000 BTU/h, ideal for medium-sized rooms.
-
Heating capacity down to -27°C: thanks to SHARP’s certified “extreme cold” technology, the ZU1 delivers consistent performance even in Quebec’s severe cold.
-
Eco-friendly Refrigerant R32: superior energy efficiency, with a 10% reduction in consumption compared to R-410A systems.
-
SEER Rating: 21, ensuring excellent efficiency in cooling mode.
-
HSPF Rating: 12.5 (IV), optimal energy performance in heating mode.
-
Patented Plasmacluster Technology: air purification, elimination of viruses, mold, allergens, and odors.
Technical details of the installation in the Pierrefonds condo
Adaptation to the housing layout
The main challenge in this project was to preserve the interior aesthetics of the condo while ensuring an installation that complies with electrical safety and performance standards. Here are the key details:
-
Mounting wall: the heat pump was installed on a load-bearing wall adjacent to a large bay window, allowing for optimal air distribution in the main living space.
-
Discreet ducts: the refrigerant and electrical ducts were carefully concealed using a flexible white cover matching the wall color.
-
Gravity drainage: a natural slope was maintained to allow optimal condensation drainage.
-
Access to the outdoor unit: the outdoor unit was installed on a protected balcony at the back, thus reducing noise and vibrations inside the dwelling.
Concrete benefits for the client
The condo owner was looking for a discreet, quiet, and efficient system to replace an old portable air conditioner. Here are the immediate benefits observed:
-
Quiet operation: with an indoor noise level as low as 23 dB, the system is practically inaudible, even at full power.
-
Quick comfort: thanks to Inverter technology, the desired temperature is reached in half the time of a conventional device.
-
Purified air quality: Plasmacluster technology ensures continuous purification of the ambient air, essential for sensitive or allergic individuals.
-
Notable energy savings: the client benefits from a significant reduction in their electricity bill, especially in heating mode during winter.
A heat pump eligible for subsidies
The SHARP ZU1 12000 BTU wall-mounted heat pump, installed by AirGreen in Pierrefonds, is eligible for Hydro-Québec’s LogisVert subsidy program, subject to certain conditions. This program can offer up to $1,204 for this type of installation.
We assist each client with administrative procedures, making it easier to obtain the subsidy quickly after installation.
Impeccable finish and connected technology
Intuitive remote control and smart options
The device comes with a wall-mounted remote control equipped with a built-in temperature sensor. The owner can manage:
-
Operating modes (heating, cooling, dehumidification).
-
Fan speed.
-
Direction of the louvers (up/down, right/left).
-
Weekly programming.
Although the ZU1 series does not have the advanced motion detection features (reserved for the ZHU series), the Wi-Fi control via the SHARP mobile app offers a highly appreciated remote management comfort.

AirGreen: your expert in installing SHARP ZU1 heat pumps in Pierrefonds and throughout Greater Montreal
Whether it is to improve your winter comfort, purify your indoor air, or reduce your energy expenses, the SHARP ZU1 heat pumps installed by AirGreen represent a smart, reliable, and durable choice.
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.
