It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.
The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.
A shut-off switch near the outdoor unit isolates it safely for service.
Sitting on the indoor module, it moves heat between the house air and the refrigerant.
Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.
Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.
It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.
It runs the heat pump and the backup heat. It must be compatible with the installed system.
A Glimpse into the Future of Home Heating with Gree Flexx
When the chilly winds of Repentigny threaten to pierce through the warmth of your home, having a reliable and efficient heating system isn't just a luxury; it's a necessity. This winter, a local family chose AirGreen, your trusted HVAC experts in Montréal, Laval, Longueuil, and beyond, for a significant upgrade to their home's comfort system. They selected the Gree Flexx Electric Furnace, a decision that not only enhances their living comfort but also aligns with sustainable energy use.
Cutting-Edge Technology and Design
The Gree Flexx Electric Furnace stands out in the HVAC market for its remarkable energy efficiency and robust performance. Here’s what makes the Flexx model not just any furnace, but a true centerpiece of home heating:
- Model Specifications: The Gree Flexx model boasts a 3-ton capacity, tailored for medium to large homes. With dimensions of 21.25 x 48.25 x 21.25 inches, it fits seamlessly into existing HVAC systems.
- Extreme Weather Capability: Designed to deliver heating even at temperatures as low as -30°C, the Flexx ensures your home remains a warm haven no matter how fierce the weather outside gets.
- Sound Optimization: At an exterior sound pressure level of just 45 dB(A), it operates more quietly than a typical conversation, ensuring your home peace isn't disrupted.
- Advanced Features: Features like the illuminated wireless remote control, eco mode, and automatic changeover provide convenience and adaptability to all weather conditions.
Installation Story: Beyond the Technicalities
The installation in Repentigny wasn't just about technical specifications; it was a narrative of transforming a house into a home. The family, having recently faced the harshness of an unusually cold winter, decided it was time to upgrade their aging heating system. They sought a solution that would not only provide warmth but also contribute to their goal of reducing their carbon footprint.
Choosing the Gree Flexx was a decision influenced by the model's eligibility for the $1,920 LogisVert Program by Hydro-Québec, which supports energy-efficient home improvements. This grant, coupled with potential provincial and federal grants totaling up to $5,000, made the Flexx an economically attractive option.
Why Gree Flexx?
Why did this family opt for the Gree Flexx, and why might it be the right choice for your home? Here are some compelling reasons:
- Energy Efficiency: With up to 20 SEER and 10.5 HSPF, the Flexx operates at a high efficiency, which means lower energy bills and less environmental impact.
- Reliability: The Gree brand is synonymous with quality and reliability, and the Flexx model comes with a reassuring 12-year warranty.
- Versatility: Adjustable capacity from 2 to 3 tons allows the system to be tailored to the specific needs of your home, ensuring efficient operation without overburdening your electrical system.
A Testament to Expertise
The installation process itself was a testament to AirGreen's expertise. Navigating the intricacies of integrating the Flexx into the home’s existing infrastructure required not only technical skill but also a deep understanding of the family’s needs. Our team ensured minimal disruption to their daily life, completing the installation efficiently and on schedule.
Conclusion: A Warm Home is a Happy Home
As the cold season approaches, the family in Repentigny can now look forward to a warmer home environment. More than just a heating system, their new Gree Flexx Electric Furnace is a commitment to comfort, efficiency, and environmental responsibility.

What would it look like 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.

Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. A central heat pump uses the house's ducts.
It connects to the existing ducts to heat and cool everywhere.
2. In extreme cold, electric backup heat can take over.
The indoor module (furnace or air handler) works with the heat pump and takes over in extreme cold.
3. The filter only gets changed when the unit breaks down.
A dirty filter cuts airflow. It gets checked regularly.
4. You can reuse the old unit's size without checking.
The house may have changed: insulation, windows, added rooms. Capacity is confirmed on site.
