An HVAC system optimized to withstand Repentigny's harsh winters
At AirGreen, we recently completed a complete HVAC installation of a FUJITSU ORION XLTH 12,000 BTU wall-mounted heat pump in a residence located in Repentigny, on Montreal's North Shore. This project perfectly illustrates the typical challenges encountered in Quebec's climate: humidity, freeze/thaw cycles, and constant heating needs during winter.
The client wanted to replace an old, inefficient system with a modern solution capable of providing reliable heating down to -26 °C while ensuring efficient air conditioning in summer. The objective was clear: improve thermal comfort while reducing energy costs.
Project analysis and choice of the FUJITSU ORION XLTH heat pump
Before any installation, our team conducts a rigorous assessment. In this specific case:
- Area to cover: main open-plan area with adjacent bedrooms
- Insulation: standard for a 2000s construction
- Existing heating source: electric baseboards
- Constraints: limited exterior wall and proximity to a window
We recommended the FUJITSU ORION XLTH KZAH R-32 12,000 BTU, a model perfectly suited for residential properties in Repentigny, Laval, and Montreal, particularly for:
- Its heating capacity down to -26 °C
- Its excellent energy performance (SEER2 30.5 / HSPF2 12.7)
- Its quiet operation (23 dB indoors)
- Its compatibility with the LogisVert subsidy ($1,200)
Key technical features
- Indoor model: ASUH12KZAS
- Outdoor model: AOUH12KZAH1
- Refrigerant: R-32 (eco-friendly and efficient)
- Capacity: 12,000 BTU
- Piping: 1/4 – 3/8
- Integrated Wi-Fi
- ENERGY STAR® (Cold Climate) certification
Challenges encountered during installation in Repentigny
Each installation has its peculiarities. In this project, several technical challenges had to be considered.
Strategic positioning of the outdoor unit
As can be seen in the image, the outdoor unit was installed on raised wall brackets. This choice is never trivial:
- Protection against snow accumulation
- Better drainage management during thaw periods
- Reduction of vibrations transmitted to the ground
We also took into account the proximity of the window to minimize noise and maximize aesthetics.
Drainage and elevation management
A point often overlooked by less experienced installers concerns drainage. At AirGreen, we apply a simple but effective method:
- Systematic testing with water after installation
- Verification of the actual drain flow
- Slope adjustment to prevent any stagnation
This helps avoid common problems such as overflow or infiltration.
Piping passage
In this project:
- Approximate total length: 18 to 20 feet
- Standard inclusion: 15 feet
- Optimized routing to limit performance losses
We used discrete pipe covers to maintain a clean and professional finish, essential in residential areas on the North Shore.
AirGreen installation process: rigor and precision
A quality installation is not limited to attaching a unit to the wall. Here are the steps we followed:
1. Preparation and drilling
- Verification of wall structures
- Precise drilling to prevent any air infiltration
2. Installation of supports
- Robust wall supports
- Perfect leveling to ensure stability
3. Refrigeration connection
- Professional brazing
- Insulation of lines
- Leak test
4. Vacuum pulling
- Complete elimination of moisture and air
- Critical step for compressor durability
5. Commissioning
- Parameter calibration
- Full test in heating and cooling mode
Results obtained: comfort, silence and savings
From the first weeks of use, the client noticed:
- Stable heat, even on cold nights
- A noticeable reduction in the electricity bill
- Increased comfort thanks to Inverter modulation
- An extremely low noise level
This type of feedback is common with the FUJITSU ORION XLTH, particularly in cities like Repentigny, Terrebonne or Mascouche, where temperature variations are significant.
Why choose a FUJITSU ORION XLTH heat pump in Repentigny?
Adapted to Quebec's climatic realities
Unlike many standard models, this heat pump:
- Continues to heat efficiently in very cold weather
- Avoids excessive use of electric baseboards
- Maintains constant comfort without fluctuations
Reduction of energy costs
Thanks to its high efficiency:
- Less consumption in winter
- Efficient air conditioning in summer
- Accelerated return on investment
LogisVert subsidy
With financial aid up to $1,200, this installation becomes even more advantageous for homeowners in the North Shore, Montreal and Longueuil.
Mistakes to avoid during an HVAC installation
Throughout our projects, we have identified several common mistakes:
- Installing the outdoor unit too low (risk of ice)
- Neglecting drainage
- Under-sizing or over-sizing the machine
- Omitting vacuum pulling
At AirGreen, every installation is carried out according to best practices to ensure performance and durability.
