A High-Performance Central HVAC Solution Designed for Laval's Climate Realities
At AirGreen, we recently completed a particularly strategic HVAC installation in Laval, involving a MIDEA EVOX G3 3-ton (36,000 BTU) central heat pump. This project perfectly illustrates our approach: rigorous analysis, adaptation to the existing building, and uncompromising technical execution.
The client wanted to replace an old, inefficient central system while improving overall thermal comfort, temperature stability between rooms, and energy consumption. The objective was clear: to obtain a reliable system capable of performing down to -30°C, without excessive reliance on auxiliary heating.
Initial Analysis and Technical Challenges Encountered
Inspection of the Existing System
During our on-site evaluation in Laval, several key elements were identified:
- Aging central system with limited efficiency
- Ductwork still functional but requiring adjustments
- Temperature imbalance between the ground floor and upstairs
- Excessive noise from the outdoor unit
We quickly confirmed that a high-performance central heat pump would be the optimal solution, rather than a simple partial replacement.
Installation Constraints
This project presented certain challenges:
- Restricted mechanical space in the technical room
- Limited access for handling the indoor unit
- Need to optimize existing airflow without complete duct reconstruction
Thanks to our on-site expertise, we opted for a configuration perfectly adapted to the building's structure, while retaining the existing infrastructure.
Why the MIDEA EVOX G3 Was the Ideal Choice
Extreme Heating Performance
The MIDEA EVOX G3 central heat pump stands out for:
- Heating capacity down to -30°C
- High power retention even in severe winter conditions
- Advanced Inverter compressor technology
For a climate like Laval's, this stability is essential. Unlike many standard systems, the EVOX G3 avoids inefficient short cycles and maintains a constant temperature.
Energy Efficiency and Tangible Savings
Here are the key performances of this model:
- SEER2: 17.7
- HSPF2: 10.0
- EER2: 12.0
- ENERGY STAR® (cold climate) certification
Result: a significant reduction in electricity costs, particularly during prolonged heating periods.
In this specific project in Laval, the client observed from the first few weeks:
- Improved thermal stability
- Reduced reliance on auxiliary heating
- More predictable consumption
Eco-friendly R-454B Refrigerant
An increasingly important point for our customers:
- Low environmental impact R-454B refrigerant
- Significantly reduced GWP (global warming potential)
- Compliance with modern environmental standards
This installation is thus part of a sustainable approach, without compromising performance.
