Strategic HVAC Installation for Maximized Comfort in Bois-des-Filions
In a quiet residential area of Bois-des-Filions, our AirGreen team recently completed a full HVAC installation of a 3-ton MIDEA EVOX G3 central heat pump. This project perfectly illustrates the real challenges faced by homeowners on the North Shore: replacing an aging system while optimizing thermal comfort, energy consumption, and reliability during periods of extreme cold.
The client wanted a central system capable of maintaining constant heat even below -25°C, while also providing efficient air conditioning in summer. After a rigorous technical evaluation, the MIDEA EVOX G3 36,000 BTU emerged as a perfectly suited solution.
Technical Project Analysis: A Typical House, Very Real Challenges
Initial Inspection and Observed Constraints
During our on-site visit, several elements caught our attention:
- Existing central system partially inefficient
- Uneven air distribution between floors
- Limited mechanical space in the basement
- Outdoor support to be adapted for secure wall mounting
The outdoor unit was installed on a robust wall mount (visible in the photo), which allows for:
- Better protection against accumulated snow
- Reduced ground vibrations
- Optimized air circulation
This type of installation is common in areas like Laval, Bois-des-Filions, or certain parts of Montreal, where ground space is limited or exposed.
Why the MIDEA EVOX G3 Central Heat Pump is a Smart Choice
Extreme Heating Performance
The MIDEA EVOX G3 is designed for Quebec's climate:
- Efficient heating down to -30°C
- Stable performance maintained at low temperatures
- Inverter technology for intelligent modulation
In this project, it means a comfortable home without excessive reliance on auxiliary heating.
Certified Energy Efficiency
The technical specifications speak for themselves:
- SEER2: 17.7
- HSPF2: 10.0
- ENERGY STAR® Cold Climate
Concrete results for the client:
- Significant reduction in energy costs
- Uniform temperature throughout the house
- Fewer on/off cycles, thus greater durability

3. Indoor Unit Integration
The indoor unit (model MAUSE-H36B-2A) was installed in the technical space:
- Connection to existing ducts
- Airflow optimization
- Ventilation system calibration
4. Refrigerant Connection and Testing
- Precisely installed 3/8 – 3/4 piping
- Full leak test
- Vacuum pull to ensure durability
5. Commissioning and Calibration
- Airflow verification
- Thermostat calibration
- Testing in heating and cooling modes

Expert Advice for Homeowners
Choosing the Right Capacity
A common mistake is oversizing or undersizing:
- 3 tons = ideal for medium to large homes
- Essential thermal analysis before installation
Importance of Professional Installation
Even the best machine can underperform if:
- The installation is poorly done
- The vacuum is neglected
- The ducts are poorly balanced
At AirGreen, every detail matters.
Recommended Maintenance
To ensure longevity:
- Annual cleaning
- System check
- Filter replacement
