Custom HVAC Installation in an Urban Brick Environment: Efficiency, Discretion, and Durability
At AirGreen, every HVAC installation represents an opportunity to demonstrate our technical rigor and understanding of the specific realities of homes on the South Shore, particularly in Sainte-Catherine. This project involving the installation of a FUJITSU ORION XLTH+ 12,000 BTU mini split heat pump perfectly illustrates how a well-thought-out solution can transform indoor comfort while respecting the architectural constraints of an existing building.
Optimized Outdoor Configuration for Durability
Elevated Stand Installation: A Strategic Choice
In this project, the outdoor unit was installed on an elevated aluminum stand, solidly anchored to the ground. This choice is never trivial:
- Protection against snow accumulation in winter (crucial for Quebec's climate)
- Reduction of vibrations transmitted to the structure
- Improved air circulation around the unit
- Easier access for HVAC maintenance
Unlike a wall-mounted installation, often used in Montreal or Laval, the ground stand is better suited here to the building's configuration and the presence of a brick wall with a concrete ledge.
Clean and Efficient Management of Refrigerant Lines
The refrigerant lines were carefully routed through the exterior wall, protected by a white insulating sleeve, then covered with an aesthetic red cover matching the facade.
This detail, often overlooked by other contractors, makes all the difference:
- Protection against bad weather
- Preservation of thermal insulation
- Harmonious visual finish with the building
At AirGreen, we always insist on this type of finish, because an HVAC installation must not only be efficient — it must also be clean and visually durable.
Specific Challenges Encountered in Sainte-Catherine
Brick Wall and Concrete Window Sill
The main challenge of this installation came from the exterior wall structure:
- Solid brick wall
- Thick concrete window sill
- Restricted space for conduit passage
To overcome this constraint, we have:
- Performed precise drilling with an adapted slope for drainage
- Used specialized tools to prevent cracks in the brick
- Strategically positioned the passage under the concrete sill
This type of intervention requires great precision, as an error can compromise the waterproofing or integrity of the wall.
Optimal Positioning of the Outdoor Unit
Given the limited space between the wall and the circulation area, we optimized the location of the outdoor unit to:
- Respect the minimum distances specified by the FUJITSU manufacturer
- Ensure proper ventilation
- Avoid any future obstruction
This type of consideration is essential to guarantee the long-term performance of the mini split heat pump.
The FUJITSU ORION XLTH+ Heat Pump: A Strategic Choice for Quebec's Climate
Exceptional Heating Performance Down to -30°C
The FUJITSU ORION XLTH+ 12,000 BTU is specifically designed for Quebec's harsh winters. It offers:
- Guaranteed heating down to -30°C
- Inverter technology for precise modulation
- High energy efficiency (SEER2 28.7, HSPF2 13.0)
For residents of Sainte-Catherine, this means constant comfort even during periods of extreme cold, without relying solely on electric heating.
Silence and Indoor Comfort
With an indoor sound level as low as 26 dB, this unit ensures:
- A quiet environment
- Optimal comfort in living spaces
- Appreciated discretion in bedrooms or home offices
Connectivity and Smart Control
The model includes integrated Wi-Fi, allowing for:
- Remote control via smartphone
- Smart programming
- Optimization of energy consumption
Subsidies and Savings: A Concrete Advantage
This installation is eligible for Hydro-Québec's LogisVert program, offering a subsidy of approximately $1,296 for this type of system.
This allows for:
- Significant reduction of the initial cost
- Improved return on investment
- Encouraging the adoption of energy-efficient solutions
At AirGreen, we always assist our clients in the steps to obtain these financial aids.
Key Steps of AirGreen Installation
Preparation and Analysis
Before any installation:
- Complete site inspection
- Validation of technical constraints
- Choice of optimal location
Technical Installation
- Precise wall drilling
- Installation of the outdoor unit on a stand
- Connection of refrigerant lines
- Secure electrical connection
Quality Procedures
We systematically perform:
- Pressure test to detect any leaks
- Vacuum pull (micron test) to ensure absence of moisture
- Complete functional verification
These steps are essential to ensure the longevity of the system.
Common Mistakes to Avoid During HVAC Installation
Many poorly executed installations in the Longueuil or North Shore region exhibit preventable problems:
- Incorrect conduit slope → water accumulation
- Absence of vacuum pull → system contamination
- Unstable support → vibrations and noise
At AirGreen, we have often been called to correct these types of errors. A well-done installation from the start avoids significant long-term costs.
