Why Choose Gree Flexx for Your Home?
The HVAC industry is continually evolving, presenting more efficient and sustainable solutions to heating and cooling needs. Among these innovative offerings, the Gree Flexx Electric Furnace stands out, especially when installed by a trusted name like AirGreen. Recently, a homeowner in Longueuil decided to upgrade their heating system, and the results were nothing short of impressive.
Project Overview: A Seamless Upgrade in Longueuil
The installation took place in Longueuil, a vibrant community that values modern living and eco-friendly choices. The homeowner, frustrated by frequent breakdowns of an old furnace, was eager to leverage the Hydro-Québec LogisVert Grant. This grant offers substantial savings, making it an opportune time to enhance home comfort systems with more reliable and energy-efficient solutions.
Choosing the Right Model: Gree Flexx Electric Furnace
When it comes to selecting a furnace, several factors come into play, but the Gree Flexx model ticks all the boxes for homeowners looking for efficiency, compact design, and longevity:
- Efficiency and Performance: With a 3 Ton capacity, the Gree Flexx provides a cooling capacity of 36,000 BTU, along with an impressive 20 SEER energy efficiency. It ensures significant energy savings while maintaining optimal home comfort.
- Compact and Quiet Operation: The unit's dimensions (21.25 x 48.25 x 21.25 inches) make it an ideal fit for small spaces, such as closets, ensuring it doesn't intrude into living areas. Furthermore, its exterior sound pressure levels are as low as 45 dB(A), making it one of the quietest in the market.
- Advanced Features for Enhanced Comfort: This model boasts a plethora of advanced features including:
- Eco Mode and Powerful Operation Mode
- Illuminated Wireless Remote Control
- Automatic Changeover (heat pump only), ensuring seamless transition between heating and cooling
- Auto-Fan Speed Control, Automatic Restart after power failures, and a Timer Function with optional Wi-Fi control
Installation Highlights: A Testimony to Quality Service
AirGreen's approach to installation is meticulous, ensuring every aspect of the setup is perfect. For this installation, reusing the existing pipes and electrical wiring not only saved costs but also reduced the environmental impact. The AirGreen team conducted thorough checks for leaks and cleaned the old pipes to ensure they were free of any contaminants, affirming our commitment to quality and detail.
Client Satisfaction: A Core Measure of Success
The homeowner was particularly impressed with the thoroughness of the installation process and the professional service provided by AirGreen. The peace of mind provided by the 12-year warranty on parts and compressor directly from Gree was a significant factor in their satisfaction. The fact that this model could meet the dual needs of being compact and yet powerful made the Gree Flexx an unrivaled choice for their home’s specific requirements.
Economic and Environmental Benefits
The decision to upgrade to the Gree Flexx was also economically advantageous. With the Hydro-Québec LogisVert Grant, the homeowner saved $2,880, substantially offsetting the initial cost of the system. This, combined with the long-term savings on energy bills due to the unit's high efficiency, illustrates the dual benefits of this installation — both financial and environmental.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
