The four-season comfort of a brick home, without compromising on aesthetics
At AirGreen , we transform Montreal homes into havens of comfort, summer and winter. This HVAC installation in a residential area of Rosemont–La Petite-Patrie illustrates how a well-chosen and well-installed wall-mounted heat pump adds value, discretion, and energy savings to a typical brick home in the neighborhood.
Project context and client objectives
Our client had just upgraded her home's insulation and was looking for a heating and cooling solution that would ensure consistent comfort while reducing her electricity bill. The ground floor, with its semi-open concept kitchen and southwest-facing windows, became hot on the first sunny days of April. In winter, the living room lost heat in the late evening. The priorities were clear:
-
Four-season comfort with just one main feature.
-
Discreet device inside and out, respecting the style of the brick house.
-
High energy efficiency to reduce consumption compared to existing electric baseboards.
-
Neat installation that does not hinder passageways, landscaping of hedges, or access to basement windows.
After a quick thermal analysis of the living room and the heat losses, we recommended a Fujitsu Halcyon single-zone wall-mounted heat pump , sized for the main room with immediate diffusion to the corridor.
Why the Fujitsu Halcyon for Rosemont
Fujitsu's Halcyon range is one of the safe bets in Montreal for several reasons that weighed in our recommendation:
-
High efficiency and fine regulation thanks to the inverter: stable, smooth blowing.
-
Cold climate performance down to -26°C on Nordic models, very suitable for metropolitan winters.
-
Low noise levels both indoors and outdoors, an asset for green alleys and shared hedges.
-
Reliability and availability of parts, facilitating long-term HVAC maintenance .
-
Frequent eligibility for grants when the configuration meets heating efficiency criteria.
Exterior integration: discretion and durability on a brick facade
The condenser was installed on the side of the house, in the grassy driveway next to a cedar hedge . Several technical choices ensure durability and aesthetics:
-
Galvanized steel wall brackets with anti-vibration pads , installed above the snow level and above a basement window to free the passage on the ground and preserve air circulation around the unit. This height also protects the machine from projections during snow removal.
-
Short, straight refrigerant pipe run , covered in a brown/sienna exterior molding, chosen to blend in with the red brick . The cover follows the existing downspout for a clean look.
-
Condensate drainage by gravity towards a bed of draining stones far from the foundation, avoiding puddles near the basement windows.
-
Regulatory clearances respected on all sides for good air intake and maintenance access.
-
Outdoor electrical section in a sealed conduit, with dedicated circuit breaker in the panel and disconnection box near the condenser, in accordance with local standards.
These technical decisions guarantee a clean facade, without visible cables, and ensure ease of intervention for our technicians during HVAC maintenance visits.
Interior integration: immediate comfort and intelligent distribution
The wall-mounted head was installed in the living room, high up on a clear interior wall, to naturally sweep the living room, dining room, and hallway leading to the bedrooms. We paid particular attention to:
-
The installation height to optimize the stratification of the air in heating and avoid direct blowing onto the rest area.
-
The passage of the connections to the shortest, facilitating the sealing control and reducing thermal losses.
-
Calibrating the flow rate and direction of the flaps to push tempered air towards the corridor without creating areas of discomfort.
Result: a rapid and uniform increase in comfort, with a heat pump that is almost imperceptible thanks to its silent operation.
Key steps of installation (AirGreen methodology)
-
Thermal and electrical assessment : taking measurements, identifying structural elements in the brick wall, checking the availability of a double pole at the panel.
-
Careful drilling with core drill and insulated sleeve, controlled slope for condensates.
-
Assembly of the brackets and laser leveling to accommodate the condenser.
-
Installation of insulated refrigerant connections , extended vacuum draw and documented leak test .
-
240V electrical connection with external disconnection and panel marking.
-
Commissioning : checking parameters, blown temperatures, intensities, and programming instructions.
-
Instructions for use : modes, filter management, instructions during freezing periods, clearances to be maintained around the unit.
This methodology, proven on hundreds of construction sites in Montreal, Laval, Longueuil, North Shore and South Shore , ensures a compliant, durable and efficient HVAC installation .
Sizing and performance: what we are specifically aiming for
Choosing the power (BTU/h) of a wall-mounted heat pump is not just about the surface area. We have integrated:
-
Orientation and afternoon solar gains.
-
Quality of the envelope (recent insulation, high-performance windows).
-
Openings between rooms and ceiling height.
-
Usage scenarios (daytime presence, preferred heating and air conditioning settings).
The chosen sizing aims for low-speed operation most of the time. This strategy maximizes seasonal efficiency (heating and air conditioning) and reduces perceived noise , while extending the compressor's lifespan.
Grants and compliance: comprehensive support
Depending on the specific configuration and model, the Fujitsu Halcyon may meet the criteria for grant programs available in Quebec. Our team assists customers with:
-
Eligibility verification (efficiency, low temperature heating capacity).
-
Preparation of supporting documents (certificate numbers, photos of the installation, detailed invoices).
-
Submission to municipal or provincial programs where applicable.
At the same time, we provide a complete installation file : serial numbers, commissioning sheet, maintenance recommendations, and warranty reminders.
Technical execution details: the pluses that make the difference
-
Short connections (only a few meters), limiting losses and simplifying maintenance.
-
Discreet exterior cladding , color matching the decor, stainless steel fasteners to counter corrosion.
-
Frost management : sufficient height and rear clearance to prevent the accumulation of snow blown by winter winds.
-
Protection of wiring in risk areas (near windows, passageways).
-
Validation of slopes for gravity drainage, in order to avoid any stagnation of water near the foundations.
These details, which are not very visible at first glance, determine the reliability and performance of the system in the long term.
Recommended maintenance: simple, regular and effective
To maintain optimal performance:
-
Clean the internal filters every 4 to 8 weeks during periods of heavy use.
-
Clearance around the condenser : keep hedges and vegetation away for good air circulation.
-
Annual inspection by AirGreen: checking the defrost cycle, tightening connections, measuring blown temperatures and reminding you of good seasonal practices.
This preventative HVAC maintenance extends the life of the heat pump and secures energy savings.
Results obtained and customer feedback
As soon as it was put into operation , the temperature in the living room stabilized quickly despite a sunny afternoon. In the evening, the heating setting maintains a comfortable atmosphere without overheating, with a barely perceptible noise level . The customer particularly appreciates:
-
The visual discretion of the condenser, raised and well integrated into the facade.
-
More homogeneous air, without drafts.
-
Lower operating costs compared to baseboards.
Best Practices for Rosemont Brick Homes
-
Favor a raised installation of the condenser for snow and maintenance of the surroundings.
-
Covering to match existing brick or downspouts.
-
Avoid circuitous connection routes : the shorter it is, the more reliable and efficient it is.
-
Provide service access around the unit and under the support, especially above basement windows.
-
Size for modulating operation and not for short duration extreme peak.
