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.

Why the Gree Flexx Was the Perfect Fit
Our client in Laval faced recurring issues with their old furnace, which required frequent and costly repairs.

The Installation Process: Detail-Oriented and Professional
Our approach to the installation in Laval was thorough and meticulous, ensuring that every component functioned perfectly:
- Old System Evaluation: We started by evaluating the existing setup, ensuring the new unit could integrate smoothly.
- Reusing Existing Infrastructure: To minimize disruption and cost, we reused the old pipes and electrical wiring, which were still in excellent condition.
- Precise Location Changes: Although the furnace remained in the same location, adjustments were made to the heat pump's placement, improving the system's overall efficacy and aesthetic.
- Quality Checks: We conducted extensive tests on the old pipes for leaks and cleaned them thoroughly to prevent any future issues.

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.
