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 Smooth Transition: From Old to Modern
The Story
In the picturesque town of Boisbriand, nestled on Montreal’s North Shore, a story of transformation unfolded. A homeowner, having relied on an old heat pump for over 15 years, faced a dilemma. The once-reliable machine had finally given out, leaving the resident at a standstill. But, as fate would have it, AirGreen was there to rescue him.
The Initial Call
Our team at AirGreen was initially called for what seemed like a routine repair job. However, after inspection, it became clear that the old heat pump was beyond repair. Replacement parts were like rare treasures, and even if obtained, the repair would have taken an entire day, costing the homeowner a small fortune.
The AirGreen Solution
Rather than patching up the old, we saw an opportunity for renewal. We presented the homeowner with an alternative: The Gree Flexx Central Heat Pump. Not only was it a state-of-the-art machine, but it also came with an impressive federal rebate of $5000, making the switch both timely and economical.
Why Choose Gree Flexx?
- Heating Capacity: Even at a freezing -30°C, the Gree Flexx doesn’t flinch. It ensures the entire home stays warm and comfortable.
- Cooling Capacity: With an impressive 60,000 BTU, summers are a breeze.
- Quiet Operation: The previous machine was a nuisance to the neighborhood with its high noise levels. The Gree Flexx, with a sound pressure level of only 58.0 dB(A), is a silent guardian.

The Installation Experience
Our skilled technicians ensured the installation was a straightforward replacement, hassle-free. The homeowner’s joy was palpable, not only because of the new machine’s capabilities but also due to significant savings from federal and provincial rebates, up to $5000!
Neighbors, previously annoyed by the old machine’s cacophony, were in for a pleasant surprise. The quiet operation of the Gree Flexx was music to their ears. The homeowner’s residence, already a beautiful home, now had an efficient and silent guardian ensuring comfort year-round.

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.
