A high-performance HVAC solution perfectly suited for a Saint-Bruno residence
At AirGreen, we recently completed a full HVAC installation of a MIDEA EVOX G3 3-ton central heat pump in a residential property located in Saint-Bruno, on Montreal's South Shore. This project perfectly illustrates the modern demands of Quebec homeowners: energy efficiency, uniform comfort, performance in extreme cold, and long-term cost reduction.
From the first technical visit, it was clear that the client was looking for a solution capable of replacing an old central system, while improving air distribution and thermal stability throughout the house. Thanks to our field expertise and rigorous needs analysis, we recommended the MIDEA EVOX G3, a model known for its robustness and its ability to perform down to -30°C, making it a strategic choice for Quebec's harsh winters.
Custom installation with mastered technical constraints
Initial analysis and specific project challenges
The residence presented several typical technical challenges for South Shore homes:
- Existing ducts requiring adaptation to optimize airflow
- Restricted mechanical space in the basement
- Need for silent integration in a dense residential environment
- Clear objective to reduce energy consumption without compromising comfort
Our team performed a complete ventilation system assessment, including static pressure, duct configuration, and available electrical capacity. This step is essential to ensure that the central heat pump operates at its full potential.
Outdoor unit installation and space management
The outdoor unit, visible in the image, was installed on robust wall brackets to:
- Protect the equipment from snow accumulation
- Ensure optimal air circulation
- Minimize vibrations transmitted to the structure
We also paid particular attention to the aesthetic management of refrigerant pipes and wiring, in order to preserve the exterior appearance of the property.
MIDEA EVOX G3: A central heat pump designed for the Quebec climate
Energy performance and adapted power
The MIDEA EVOX G3 3-ton (36,000 BTU) offers a remarkable combination of power and efficiency:
- SEER2: 17.7
- HSPF2: 10.0
- EER2: 12.0
- ENERGY STAR® Cold Climate Certification
These performances lead to a significant reduction in energy costs, particularly in regions such as Montreal, Laval, Longueuil, North Shore, and South Shore, where climatic variations are significant.
Reliable heating down to -30°C
One of the main advantages of this heat pump is its ability to maintain stable performance even during periods of extreme cold. Unlike some systems that lose efficiency below -20°C, the EVOX G3 continues to provide consistent heat.
In this Saint-Bruno project, this meant:
- Less reliance on auxiliary heating
- Uniform temperature in all rooms
- Increased comfort even during cold snaps
Inverter technology and smart comfort
Precise regulation and energy savings
Thanks to Inverter technology, the compressor continuously adjusts its speed according to the building's actual needs. This allows for:
- Reduced on/off cycles
- Optimized energy consumption
- Stable indoor temperature
In this installation, the client immediately noticed a difference: no more abrupt temperature variations, but rather constant and pleasant comfort.
Integrated WiFi and remote control
The heat pump is equipped with an integrated WiFi module, allowing for:
- Remote control via mobile application
- Personalized hourly programming
- Energy consumption monitoring
This type of control is particularly appreciated by modern homeowners who wish to optimize their comfort while keeping an eye on their energy expenses.
Eco-friendly R-454B refrigerant: a responsible choice
The MIDEA EVOX G3 uses R-454B gas, known for its low environmental impact:
- Reduced GWP (Global Warming Potential)
- Compliance with new environmental standards
- More sustainable alternative to older refrigerants
At AirGreen, we systematically prioritize solutions that combine performance and environmental responsibility.
AirGreen installation process: rigor and precision
Key project steps
For this installation in Saint-Bruno, our team followed a strict protocol:
- Complete inspection of the existing system
- Precise sizing (3 tons)
- Installation of the indoor unit (air handler)
- Refrigerant line connection (3/8 - 3/4)
- Vacuum draw and micron test
- Commissioning and calibration
Each step is carried out according to the highest standards of the HVAC industry.
Importance of vacuum draw (micron test)
We always emphasize this critical step:
- Elimination of moisture in the system
- Prevention of micro-leaks
- Guaranteed compressor longevity
A poorly executed vacuum draw is one of the most common errors in heat pump installations.
LogisVert subsidy: a major financial advantage
For this installation, the client was able to benefit from a LogisVert provincial subsidy of up to $3720.
We assist each client with:
- Eligibility validation
- Document preparation
- File follow-up
This significantly reduces the total project cost.
Client feedback and observed results
A few weeks after the installation, the client shared their observations with us:
- Significantly improved thermal comfort
- Noticeable reduction in electricity costs
- Silent operation of the outdoor unit
- Better indoor air quality
This type of feedback confirms the relevance of the MIDEA EVOX G3 in residential contexts like that of Saint-Bruno.
Practical advice for future buyers
Choosing the right central heat pump
