Strategic HVAC Installation in a Confined Space: Performance and Precision at the Heart of the Project
At AirGreen, every HVAC installation presents its own technical challenges. In Montreal East, we recently installed a FUJITSU ORION XLTH 12,000 BTU wall-mounted heat pump in a unique architectural context: a dwelling located under a balcony, with an exposed wooden structure and an old brick wall.
This type of environment requires a rigorous approach, both mechanically and aesthetically. The objective was clear: to offer optimal four-season comfort, while respecting the physical constraints of the building and the durability requirements specific to the Greater Montreal climate.
Site Analysis: Real Constraints and Technical Decisions
Limited Outdoor Space Under Balcony
The outdoor unit was installed under a wooden balcony, a common configuration in Montreal plexes and buildings, but rarely simple to execute correctly.
The main challenges encountered:
- Restricted height between the ground and the balcony structure
- Limited air circulation, essential for the heat pump's proper functioning
- Drainage management (condensation water and winter defrosting)
- Protection against indirect weather (rain, ice, blown snow accumulation)
To address these constraints, we opted for a wall-mounted installation on reinforced metal supports, solidly anchored in the brick.
Elevated Wall Mount: A Strategic Choice
The FUJITSU outdoor unit was mounted on a robust wall bracket, allowing for:
- Sufficient elevation to prevent snow accumulation in winter
- Better water drainage during defrost cycles
- Reduced vibrations transmitted to the structure
- Optimized air circulation around the unit
This type of installation is particularly recommended in dense urban areas like Montreal East, Laval, or Longueuil, where ground space is limited.
The FUJITSU ORION XLTH 12,000 BTU: A Choice Suited to the Quebec Climate
Heating Performance Down to -26°C
This FUJITSU wall-mounted heat pump model is designed to withstand harsh Quebec winters. With effective heating capacity down to -26°C, it maintains stable thermal comfort without excessive reliance on auxiliary heating.
In this project in Montreal East, the client wanted to reduce their dependence on electric baseboards, while ensuring a constant temperature in their living space.
Inverter Technology and Intelligent Modulation
Thanks to Inverter technology:
- Power adapts in real-time
- On/off cycles are reduced
- Energy consumption is optimized
Result: homogeneous temperature, without unpleasant fluctuations.
Technical Details of the Installation
Piping and Wiring: Precision and Discretion
In this installation:
- Standard 1/4 - 3/8 inch piping used
- Conduits carefully aligned along the brick wall
- Electrical wiring protected and neatly secured
Given the building's configuration, we prioritized a visible but perfectly structured and aesthetic installation, avoiding any invasive modifications.
Drainage: An Often Underestimated Element
Drainage is critical, especially in an under-balcony installation.
At AirGreen, we apply a simple but effective method:
- Slope verification
- Real-world water test to validate flow
- Immediate adjustment if necessary
This ensures operation without water accumulation or risk of backflow.
Successful Aesthetic Integration
Respect for the Existing Building
The red brick wall and white windows required a certain visual harmony.
We therefore:
- Aligned the outdoor unit with existing openings
- Used discreet but strong supports
- Maintained a clean and symmetrical installation
Minimal Visual Impact
Even with an apparent installation, the result remains:
- Professional
- Discreet
- Durable over time
Indoor Comfort: Silence and Efficiency
Ultra-Low Noise Level
The FUJITSU ORION XLTH offers:
- Around 23 dB(A) indoors
- Around 47 dB(A) outdoors
In a dense residential environment like Montreal East, this makes a real difference.
Optimal Air Distribution
Thanks to:
- Automatic vertical louvers
- Homogeneous air distribution
- Smart modes
Comfort is constant, with no cold or hot spots.
LogisVert Subsidy: A Concrete Financial Advantage
This model is eligible for a $1,200 subsidy under the LogisVert program.
For the client:
- Immediate cost reduction
- Accelerated return on investment
- More financially accessible solution
At AirGreen, we always support our clients through these processes.
