A Strategic HVAC Installation to Combat Boisbriand's Harsh Winters
At AirGreen, we recently completed a comprehensive HVAC installation in Boisbriand, on the North Shore, featuring a MIDEA EVOX G3 3-ton (36,000 BTU) central heat pump. This project perfectly illustrates our approach: rigorous technical execution, a deep understanding of customer needs, and equipment selection tailored to Quebec's climatic realities.
The client, owner of a single-family home built in the 2000s, wanted to replace an old, inefficient, energy-consuming, and noisy central system. The objective was clear: improve thermal comfort, reduce energy costs, and benefit from available subsidies, notably the LogisVert program.
A Central System Designed for Cold Climate Performance
Technical Specifications of the Installed MIDEA EVOX G3
The MIDEA EVOX G3 | 3-ton central heat pump we installed stands out for its specifications particularly suited to the climate of Montreal, Laval, and the North Shore:
- Cooling Capacity: 36,000 BTU
- Heating Capacity down to -30°C
- SEER2: 17.7
- HSPF2: 10.0
- EER2: 12.0
- ENERGY STAR® Certification (Cold Climate)
- Eco-friendly R-454B Refrigerant
- Integrated WiFi
- Voltage: 220V
- Piping: 3/8 – 3/4
- AHRI: 215471343
This model is renowned for its thermal stability, even during periods of intense cold. Unlike some systems that lose efficiency below -20°C, the EVOX G3 maintains consistent performance, reducing the need for auxiliary heating.
A Significant Subsidy Not to Be Overlooked
For this project in Boisbriand, the client was able to benefit from a LogisVert subsidy of $3,720, which significantly improved the return on investment. At AirGreen, we systematically assist our clients in the steps to maximize these financial aids.
Technical Challenges Encountered During Installation
Restricted Access and Complex Duct Configuration
One of the main challenges of this installation concerned access to the existing central system. The indoor unit had to be installed in a relatively narrow mechanical space, with ducts already in place but requiring adjustments.
We had to:
- Adapt connections without compromising airflow
- Optimize duct alignment to avoid pressure losses
- Install anti-vibration supports to reduce noise
Thanks to our expertise in central heat pump installation, we were able to turn this constraint into an advantage by improving overall air circulation in the house.
Refrigerant Line Management and Outdoor Protection
As seen in the project image, the outdoor unit was installed with meticulous attention to detail:
- Complete insulation of refrigerant lines
- Mechanical protection with robust casing
- Installation of a standard-compliant electrical disconnect
- Strategic positioning to minimize noise and maximize efficiency
We also performed a complete vacuum pull with micron test, ensuring the total absence of moisture in the system — a crucial step often overlooked by less rigorous installers.
Why This Choice Was Optimal for This Client
An Intelligent Replacement of an Aging System
The previous system was still functional, but at a very low efficiency. The client observed:
- High electricity bills
- Uneven heat distribution
- Excessive noise
With the MIDEA EVOX G3, these problems were eliminated from the first days of use.
Inverter Technology for Constant Comfort
Inverter technology allows real-time adjustment of compressor power. The result:
- Stable temperature
- Fewer on/off cycles
- Reduced energy consumption
In this Boisbriand home, this translated into a much more uniform sense of comfort, without unpleasant fluctuations.
Client Feedback After Installation
A few weeks after commissioning, the client shared their experience with us:
- Immediately improved comfort
- Remarkable quietness of the outdoor unit
- Easy control via the WiFi application
- Significant reduction in energy consumption
This type of feedback is common with the MIDEA EVOX G3 heat pump, which we have already installed multiple times in Laval, Longueuil, and Montreal.
Best Practices and Tips for a Successful Installation
What We Always Recommend
To guarantee the longevity and performance of a system like this, we emphasize several essential points:
- Always perform an accurate sizing (load calculation)
- Never neglect vacuum pulling and pressure tests
- Ensure good duct insulation
- Install high-performance filters (MERV 13 recommended)
Mistakes to Avoid
- Installing an oversized or undersized heat pump
- Reusing old ducts without inspection
- Neglecting annual maintenance
At AirGreen, every HVAC installation in Montreal, Laval, or on the North Shore is carried out according to strict, uncompromising standards.
A Sustainable Solution for Quebec Homes
The MIDEA EVOX G3 central heat pump represents a wise choice for homeowners wishing to:
- Reduce their carbon footprint
- Benefit from a reliable long-term system
- Take advantage of government subsidies
- Improve their comfort in summer and winter
In a context where energy costs are rising, investing in a high-performance system becomes a strategic decision.
