A Complete Transformation of Residential Comfort Through Strategic HVAC Installation
At AirGreen, we recently completed a particularly interesting HVAC installation in Charlemagne, on the North Shore. This involved replacing an old, inefficient system with a 3-ton (36,000 BTU) MIDEA EVOX G3 central heat pump. This project perfectly illustrates how rigorous planning, combined with precise technical execution, optimizes comfort, energy performance, and system durability.
Project Context and Challenges Encountered in Charlemagne
A Restrictive Outdoor Configuration
Upon arrival at the site, we noted several specific constraints:
- Restricted space between the exterior wall and an adjacent structure
- Presence of an old, poorly positioned system
- Limited air circulation around the initial location
- Imperfect drainage that could affect the outdoor unit
The outdoor unit had to be installed with a minimum clearance distance respected, while ensuring good ventilation to maintain optimal heat pump performance.
Adaptation to Existing Ducts
Inside, the existing central system presented:
- Slightly unbalanced ducts
- Uneven air distribution between floors
- Insufficient filtration
We therefore had to adjust the network to ensure perfect compatibility with the MIDEA EVOX G3, while improving overall air circulation.

The MIDEA EVOX G3 proved to be the ideal solution thanks to its ability to maintain stable performance even in extreme conditions.
Key Steps of the Installation Carried out by AirGreen
1. Thermal Analysis and Sizing
Before any installation, we conducted a complete evaluation:
- Heat load calculation
- Insulation analysis
- Verification of existing ducts
- Identification of energy losses
This step is essential to avoid a common mistake: oversizing or undersizing the system.
2. Outdoor Unit Installation
We proceeded with:
- Installation on a solid elevated base
- Adjustment of positioning to optimize air circulation
- Stabilization to reduce vibrations
The choice of a suitable support protected the unit against snow accumulation and humidity, a critical factor in the Montreal and North Shore region.
3. Refrigerant and Electrical Connections
- Piping: 3/8 – 3/4
- Complete vacuum pull with micron test
- Leak test
- Secure 220V electrical connection
At AirGreen, we insist on an impeccable vacuum pull, guaranteeing the longevity of the compressor.
4. Ventilation System Optimization
We adjusted:
- Airflows
- Registers
- Balancing between rooms
Result: homogeneous temperature distribution throughout the house.
Results Obtained After Installation
Superior Thermal Comfort
The client immediately noticed:
- Uniform temperature in all rooms
- Rapid heat-up
- Better humidity management
Reduced Energy Costs
Thanks to Inverter technology and high efficiency:
- Significant decrease in bills
- Fewer ON/OFF cycles
- Optimized consumption
Quiet Operation
Despite its power, the MIDEA EVOX G3 central heat pump offers discreet operation, particularly appreciated in this quiet residential area of Charlemagne.
Available Subsidies and Profitability
This model is eligible for a LogisVert subsidy of up to $3720.
This allows for:
- Significantly reducing the initial cost
- Accelerating the return on investment
- Encouraging a transition to efficient energy solutions
We support each client in the steps to maximize these financial aids.
Practical Advice for a Successful Installation
What to Avoid
- Installing the outdoor unit in a confined space
- Neglecting the vacuum pull
- Ignoring duct balancing
- Choosing a system without thermal analysis
