A Complete Transformation of Thermal Comfort in a Sainte-Julie Residence
At AirGreen, we recently completed a major HVAC installation in Sainte-Julie, on the South Shore of Montreal, involving a MIDEA EVOX G3 3-ton central heat pump. This project perfectly illustrates our approach: rigorous analysis, impeccable technical execution, and a constant focus on optimizing comfort and energy performance.
The client, owner of a single-family home built in the 2000s, wanted to replace an old, inefficient, and noisy central system. The objective was clear: to achieve stable heat in winter, uniform air conditioning in summer, and significantly reduce energy costs.
Why the MIDEA EVOX G3 was the ideal choice for this installation
Performance Adapted to Quebec Winters
The MIDEA EVOX G3 central heat pump stands out for its ability to maintain heating performance down to -30°C, which is essential in a region like Sainte-Julie, where winter temperatures can be extreme.
In this project, we particularly highlighted:
- A cooling capacity of 36,000 BTU
- A SEER2 of 17.7 for remarkable summer efficiency
- An HSPF2 of 10.0, guaranteeing excellent heating performance
- An ENERGY STAR® (Cold Climate) certification
These characteristics allow the system to operate efficiently all year round, without compromise.
An advantageous subsidy for the client
Thanks to the LogisVert program, our client was able to benefit from a subsidy of $3720, making this investment even more relevant. We provided full support for the administrative procedures, thus simplifying the process.
Technical Challenges Encountered on the Sainte-Julie Site
Space Constraints and Duct Optimization
One of the major challenges of this installation was the limited space in the mechanical room. The existing system occupied a poorly optimized configuration, with unbalanced ducts.
Our team had to:
- Partially reconfigure the ductwork
- Adapt the indoor unit for optimal maintenance access
- Ensure homogeneous air circulation throughout the house
Thanks to the compact design of the MIDEA EVOX G3, we were able to integrate the system without compromising performance.
Outdoor Unit Installation: Stability and Durability
As seen in the installation, the outdoor unit was mounted on robust wall brackets, which allows for:
- Better protection against snow accumulation
- Reduced vibrations transmitted to the building
- Increased system durability
We also made sure to:
- Install a secure electrical supply
- Optimize tubing passage (3/8 – 3/4)
- Perform a complete vacuum pull with micron test

Reduced Energy Costs
Thanks to Inverter technology and the more ecological R-454B refrigerant, the system continuously adjusts its power, which leads to:
- Fewer on/off cycles
- Optimized energy consumption
- A reduced monthly bill
Real Customer Testimonial (Summary)
The owner particularly appreciated:
- The stability of heating even in very cold weather
- The quiet operation of the outdoor unit
- Intelligent control via WiFi
This type of feedback is consistent in our central heat pump installations in Laval, Longueuil, and Montreal, confirming the reliability of the model.
