Discreet and efficient four-season comfort, perfectly integrated into a North Shore home
At AirGreen , we help North Shore families gain comfort and energy savings through well-designed and impeccably executed HVAC solutions . This project in Blainville highlights the installation of a Gree Livo R32 series wall-mounted heat pump , a particularly suitable choice for single-family homes in Greater Montreal thanks to its efficiency, visual simplicity, and quiet operation.
Client background and objectives
The owner wanted to efficiently cool and heat the main living area – an open-plan ground floor – without compromising the interior aesthetic or wasting space. Emphasis was placed on:
-
economical operation in summer and mid-season;
-
a discreet integration ;
-
simple maintenance to maintain performance over time.
After a technical visit, we recommended a Gree Livo R32 wall-mounted heat pump in a single-zone configuration, ideal for quickly dealing with variable thermal loads in this area of the house while maintaining low electricity consumption.
The choice of the Gree Livo R32: R-32 performance and measured comfort
The Livo R32 stands out for its inverter technology and the use of R-32 refrigerant , which improves seasonal efficiency while reducing the environmental footprint compared to previous generations. It offers:
-
fine modulation of power to avoid on/off cycles;
-
even blowing and precise temperature adjustment;
-
a contained noise level , appreciable in living rooms;
-
accessible filters that remove in seconds for maintenance.
These advantages perfectly meet the expectations of owners in Blainville, Sainte-Thérèse, Boisbriand and Laval , looking for daily comfort and energy savings without compromising on aesthetics.
Interior integration details: precision and cleanliness
The interior head was positioned above a door opening onto the courtyard , a strategic area to promote air circulation between the kitchen and living room. Our approach favors:
-
adequate clearance above and in front of the appliance to ensure suction and blowing;
-
a short through passage on the right side of the unit for refrigeration connections , power supply and condensate drain ;
-
a continuous gravity slope of the drain to avoid any risk of backflow;
-
a tight seal of the drilling and a clean interior finish , with a neat seal around the bulkhead.
The discreet display allows immediate reading of the setpoint without disturbing the visual ambiance. The choice of a high position frees up the walls and directs the airflow for rapid mixing of the volumes, limiting areas of overheating or localized coolness.
Route of connections and external interface
In order to minimize pressure losses and preserve aesthetics , we opted for a direct route through the load-bearing wall : the refrigeration connections, the cable and the drain exit from the right side of the head and reach the outside through a bulkhead . This type of configuration:
-
reduces the length of the links (and therefore the losses);
-
simplifies maintenance and future diagnosis;
-
optimizes installation time while ensuring a professional finish.
On the outside, the ducts are protected by white capping that matches the style of the facade, guaranteeing durability and resistance to bad weather —a must for Quebec winters .
AirGreen Execution Quality: What It Changes for Performance
A wall-mounted heat pump performs at its best when:
-
The positioning respects air flows and service clearances;
-
The holes are clean, watertight, and properly insulated;
-
Refrigerant connections are flared to the correct torque, pulled to a deep vacuum and tested with nitrogen ;
-
The drain has a continuous slope and opens into a safe place, protected from frost;
-
Start-up includes checking the blowing pressures , intensities and temperatures.
Our teams systematically apply these steps. The result: remarkable temperature stability , lower consumption and increased component life .
Real comfort and benefits for the owner
From the first start-up, the feeling of uniform freshness in the living area is immediate. Over a typical year, the customer benefits from:
-
rapid cooling during heat waves;
-
efficient additional heating during the off-season, limiting the use of the main system;
-
a controlled energy bill , thanks to Inverter modulation;
-
low noise level , ideal for living rooms and teleworking.
Grants and eligibility (depending on configuration)
High-efficiency R-32 wall-mounted heat pumps may be eligible for assistance programs when efficiency criteria are met (certifications, low-temperature heating performance, compliant installation). During our visits, we verify the concordance of models and accompany our customers in the process when relevant for Montreal, Laval, the North Shore and the South Shore .
HVAC maintenance: maintaining performance over time
To maintain optimal performance and healthy air quality , we recommend:
-
cleaning the filters every 4 to 8 weeks during periods of intensive use;
-
an annual check by our technicians (evaporator, condenser, pressures, electrical connections, drain);
-
a clearance of 1 m in front of the indoor unit and the absence of obstacles (thick curtains, tall furniture);
-
a check of the external capping after freeze/thaw episodes.
This simple routine extends the life of the heat pump and keeps operating costs low .
What we paid particular attention to on this project
-
Installation above the door : this location facilitates the transverse diffusion of air in the living space and limits direct air returns to the occupants.
-
Right side exit : shortest and straightest route to the outside, guaranteeing reliability and efficiency .
-
Interior finish : no visible cables, discreet bulkhead , rigorous alignment of the interior head with the lintel for a clear visual reading .
Useful tips for a similar project in Blainville, Laval or Montreal
-
Sizing : The BTU size should match the volume and insulation level of the area. An oversized unit cycles too much and loses efficiency; an undersized unit struggles to maintain the setpoint.
-
Location : Near an opening or corridor , the air is better distributed to adjacent rooms.
-
Drain : use gravity where possible; use a condensate pump only if the route requires it.
-
Maintenance : An annual contract simplifies planning and protects the warranty.
-
Aesthetics : choose a capping that matches the facade and check the mounting heights for harmonious integration.
