An HVAC Installation Designed for Real and Lasting Comfort on the South Shore
In Brossard, on Montreal's South Shore, we recently completed a full HVAC installation of a FUJITSU CENTAURI R32 3 ton (36,000 BTU) central heat pump in a typical 1990s single-family home. This type of property often presents specific challenges: existing ducts to optimize, thermal balance between floors, and increased comfort requirements in both winter and summer.
At AirGreen, we approach every project with a simple logic: a high-performance machine must be accompanied by impeccable installation, otherwise the final result will never live up to expectations. This project in Brossard is an excellent example.
A FUJITSU Central Heat Pump Adapted to Quebec's Climate Realities
Key Technical Characteristics of the Installed System
The installed FUJITSU CENTAURI R32 3 ton (36,000 BTU) has specifications particularly suited to the conditions of the greater Montreal, Laval, Longueuil, and South Shore regions:
- Cooling Capacity: 36,000 BTU
- Heating capacity down to -21 °C
- R-32 Refrigerant (new generation)
- ENERGY STAR® certified (Cold Climate)
- SEER2: 17.63 | HSPF2: 9.81 | EER2: 11.06
- Outdoor Sound Level: 56 dB(A)
- Voltage: 220V
- Piping: 3/8 - 5/8
- LogisVert Grant: up to $3,288
This type of central system allows for uniform air distribution throughout the house, unlike wall-mounted systems that operate by zones.
Specific Challenges Encountered During Installation in Brossard
1. Outdoor Support and Stability
As seen in the image, the outdoor unit was installed on a robust elevated support. This choice is never solely aesthetic:
- Protection against snow accumulation
- Vibration reduction
- Improved compressor longevity
- Easier access for HVAC maintenance
2. Strategic Unit Positioning
The outdoor location was chosen considering several essential factors:
- Optimal distance between indoor and outdoor units
- Reduced noise perceived by occupants
- Compliance with regulatory clearances
- Protection against prevailing winds
3. Optimization of Existing Ducts
In this house, existing ducts were present but had common deficiencies:
- Uneven distribution between ground floor and upper floor
- Insufficient air returns
- Some registers poorly adjusted
Our intervention included:
- Complete rebalancing of airflows
- Precise adjustment of registers
- Verification of pressure drops
Result: a consistent temperature in all rooms, which was the client's main objective.
Why a 3-Ton Central Heat Pump Is Ideal for This Type of Home
Sizing is a critical step. A 3-ton (36,000 BTU) central heat pump is generally suitable for:
- Medium to large sized homes
- Multi-story residences
- Open-plan spaces combined with closed rooms
What we absolutely avoid:
- Oversizing → short cycling, discomfort, poorly controlled humidity
- Undersizing → lack of power during cold periods
At AirGreen, we analyze:
- Building insulation
- Fenestration
- Wind exposure
- Duct configuration
The Key Role of R-32 Refrigerant in New HVAC Installations
The installed system uses R-32 refrigerant, which is becoming the industry standard.
Specifically for the client:
- Improved energy efficiency
- More modern technology
- Compatibility with new Fujitsu platforms
- Reduced environmental impact
This is not a technical detail: it indicates that the machine is designed for current and future standards.
Essential Steps of Our HVAC Installation in Brossard
Preparation and Verification
Before installation:
- Complete duct inspection
- Electrical validation (MCA / MOP)
- Piping route planning
- Condensate drainage analysis
Mechanical Installation
- Securing the outdoor unit on reinforced support
- Installing the indoor unit in the mechanical space
- Refrigerant connection (with complete vacuum evacuation)
- Line insulation
Commissioning
- Pressure test
- Micron test (stable vacuum)
- Airflow calibration
- Adjustment of operating parameters
Final Result: Comfort, Silence, and Thermal Stability
After commissioning, the client immediately noticed:
- Uniform temperature throughout the house
- Significant noise reduction
- Fast system responsiveness
- Better humidity management in summer
This type of installation literally transforms daily comfort.
Common Mistakes We Avoided on This Project
In the HVAC market, several mistakes are still too common:
Poor outdoor unit placement
→ Snow problems, noise, difficult maintenance
Duct neglect
→ Uneven comfort despite a good machine
Quick installation without calibration
→ System performant on paper, ineffective in reality
Absence of micron test
→ Risk of leaks and premature failure
At AirGreen, these steps are non-negotiable.
Available Grants and Profitability
