Installation of a Sharp wall-mounted heat pump in Duvernay (Laval)
AirGreen installed a Sharp ZU1 wall-mounted heat pump on a brick facade in Duvernay, Laval. With its raised wall bracket, integrated casing, and compliant electrical installation, it offers a high-performance and durable solution for residential heating and cooling.
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.
For this residence located in Duvernay, Laval , our AirGreen team completed the installation of aSharp wall-mounted heat pump , a high-performance, energy-efficient system perfectly suited to single-family homes in this area. The provided photo clearly shows the Sharp Eco Inverter outdoor condenser , installed on a brick wall typical of Laval homes, with meticulous finishing of the electrical and refrigerant connections.
We opted for a Sharp ZU1 model, a reliable series operating with R-32 refrigerant, known for its excellent winter heating performance and its ability to maintain a very low noise level — an advantage appreciated in the residential areas of Laval.
Project context: a brick house requiring a robust installation
The red brick facade, typical of Duvernay , imposes certain technical constraints:
-
Precise drilling into the masonry.
-
Reinforced fixings to support the condenser.
-
Aesthetic management of cabling and enclosure on a highly visible wall.
The owners wanted a discreet, efficient heating system that would reduce reliance on electric baseboard heaters, while providing consistent comfort during Laval's hot summers.
The Sharp wall-mounted heat pump was ideal: compact, robust, quiet and perfectly suited to the temperature variations of the Montreal climate.
The installed model: Sharp ZU1 – performance, reliability and energy efficiency
We selected a Sharp ZU1 , one of the brand's highest-performing wall-mounted series, available in capacities ranging from 12,000 to 24,000 BTU. Depending on the interior configuration (not visible in this photo), this installation likely corresponds to a capacity of 18,000 BTU , which is very common for open-concept ground floors or entire upper floors.
The advantages of the ZU1 model:
-
High energy efficiency (Eco Inverter) .
-
Stable performance even in extreme cold .
-
Inverter technology allows for minimal energy consumption.
-
Extremely low noise level, both indoors and outdoors.
-
Compatibility with the requirements of the LogisVert program (depending on capacity).
This model is renowned for its durability and excellent value for money, making it a frequent choice for AirGreen customers on the North Shore and in Laval.
Outdoor installation: stability, safety and aesthetics
The photo shows a carefully executed outdoor installation, including:
1. Elevated wall bracket
We installed the condenser on sturdy wall brackets in order to:
-
keep it away from snow accumulation in winter;
-
limit vibrations;
-
ensure optimal air evacuation on an unobstructed wall.
2. Management of refrigerated connections
The vertical brown casing visible in the photo protects:
-
insulated copper pipes ,
-
the condensate drain ,
-
the communication cable to the indoor unit.
A hood of this color blends well with the red brick, which helps to maintain a clean and linear aesthetic.
3. Compliant electrical connection
The dedicated external electrical box is visible right next to the device. It provides:
-
increased security ,
-
an easy service for future maintenance,
-
full compliance with the Quebec Electrical Code.
4. Optimal positioning
The condenser is located away from windows, in a well-ventilated area, and accessible for:
-
the interview,
-
defrosting in winter,
-
technical interventions.
This configuration guarantees increased longevity and maximum performance.
Interior integration: a discreet wall-mounted head
Although the photo provided shows the exterior, the indoor unit associated with a ZU1 installation is usually:
-
compact,
-
silent
-
fixed high up for optimal air diffusion,
-
equipped with a motorized flap to direct the flow.
It provides even heating in winter and gentle air conditioning in summer , suitable for multi-story houses as well as bungalows.
An ideal system for Laval winters
Thanks to this Sharp installation, the occupants will benefit from:
-
stable heating even at very low outside temperatures ,
-
a significant reduction in the electricity bill ,

And 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.
