Strategic HVAC Modernization for Consistent All-Season Comfort
In the residential sector of Chomedey in Laval, we recently completed a full HVAC installation of a MIDEA EVOX G3 3-ton central heat pump in a single-family home built in the 1990s. The owner wanted to replace an old, inefficient system combining an electric furnace and an aging central air conditioner, which had become expensive to operate and unable to maintain a stable temperature.
At AirGreen, we managed the entire project, from initial assessment to final commissioning, including optimizing the existing ducts. This project perfectly illustrates our approach: technical precision, energy efficiency, and adaptation to the climatic realities of Greater Montreal, Laval, and the North Shore.
Why the MIDEA EVOX G3 Was the Ideal Choice for This Residence
Perfectly Adapted Power: 36,000 BTU (3 tons)
After a complete thermal analysis of the building (area, insulation, orientation, air volume), we determined that a capacity of 36,000 BTU was ideal to ensure:
- Homogeneous heat distribution
- Rapid cooling in summer
- Stable performance even during cold snaps
Guaranteed Performance Down to -30°C
One of the decisive criteria for this client was winter reliability. The MIDEA EVOX G3 stands out for:
- Heating capacity down to -30°C
- Performance maintained at -25°C without major loss
- Inverter technology allowing intelligent modulation
Result: consistent heat, without abrupt cycles or discomfort.
Technical Challenges Encountered During Installation in Chomedey
Restricted Access to the Outdoor Location
The outdoor unit had to be installed on a narrow side of the house, with:
- Limited clearance
- Proximity to the foundation
- Optimized drainage
AirGreen Solution:
- Installation on a raised aluminum support
- Precise leveling to avoid vibrations
- Optimized drainage to prevent water accumulation
Reuse of Existing Ducts
The duct system was functional but required adjustments:
- Complete cleaning
- Sealing of joints
- Airflow verification
We also validated compatibility with the Computational Constant Airflow 2.0 system, ensuring optimal air circulation.
