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.
An Unmatched HVAC Installation Tailored for Comfort and Style
At AirGreen, we are dedicated to delivering top-notch HVAC solutions that combine cutting-edge technology, energy efficiency, and aesthetic discretion. Our latest project, the installation of a Gree FM Concealed Duct System, perfectly illustrates our commitment to excellence and precision. This installation, carried out in the bustling heart of Montréal, transforms the way you experience indoor comfort.
Understanding the Unique Needs of Our Client
When our team arrived at the site, we were presented with a challenge that demanded ingenuity and a tailored approach. The client required a robust yet unobtrusive heating and cooling system for their newly renovated space. The goal was to maintain clean interior lines without compromising performance. This is where the Gree FM Concealed Duct System with its 18,000 BTU compressor and three 6,000 BTU outlets came into play.
The Beauty of the Gree FM Concealed Duct System
What Makes It Stand Out?
The Gree FM Concealed Duct System is designed for those who desire efficient climate control with minimal visual impact. Here's why this system is a game changer:
- Cooling and Heating Capacity: With an 18,000 BTU compressor, this system offers powerful climate control, ensuring your home stays comfortable throughout the year, no matter the weather.
- Low Static Pressure: Ideal for installations that require compact designs, the low static pressure ensures energy efficiency while delivering a consistent airflow across all outlets.
- Energy Efficiency: Certified with Energy Star standards, the Gree system minimizes power consumption, making it an eco-friendly choice for energy-conscious homeowners.
- Quiet Operation: Operating at just 33 to 41 dB(A), this system provides a whisper-quiet environment, perfect for living spaces, offices, or bedrooms where peace is paramount.
- R-410A Refrigerant: The environmentally friendly R-410A refrigerant adds to its appeal, aligning with global efforts to minimize ozone-depleting substances.
The Installation Process: A Behind-the-Scenes Look
Our expert team embarked on this project with meticulous planning and execution. Let’s break down the steps:
Step 1: Site Assessment and Custom Planning
We began by conducting a comprehensive assessment of the client's space. The layout presented some unique obstacles, including restricted attic access and limited space between walls. Our solution? Strategic placement of ductwork to maximize air distribution while keeping everything hidden.
Step 2: Installing the Compressor Unit
We installed the 18,000 BTU compressor unit outside, ensuring optimal airflow and minimizing noise. Using state-of-the-art tools, we anchored the compressor securely and tested it to guarantee efficiency and stability.
Step 3: Concealing the Ductwork
The real magic of this project lies in the concealed ductwork. With precision, our technicians routed the ducts through narrow wall cavities, connecting them to three discreet 6,000 BTU outlets. This setup ensured even temperature distribution without any visible duct lines or bulky units cluttering the interior.
Key Features and Benefits of Our Installation
Versatile Air Return Options
The Gree system's air return options from either the bottom or the back provided the flexibility needed to adapt to the room's design. This feature allowed us to optimize air circulation while keeping the design seamless.
Integrated Condensate Pump
Water management is crucial in any HVAC system. The integrated condensate pump efficiently handles moisture, reducing the risk of water damage and ensuring smooth, maintenance-free operation.
Sentry Float Switch for Safety
To protect against overflow, the system includes a sentry float switch. This feature enhances reliability by automatically shutting down the unit if water levels rise too high, preventing damage to both the system and the property.
Our Expertise in Action
At AirGreen, our reputation is built on delivering exceptional results, and this project was no exception. Every step of the installation was handled by certified HVAC specialists, ensuring compliance with industry standards and the client's satisfaction. We even went the extra mile to fine-tune the system, optimizing it for the Montreal climate with its harsh winters and humid summers.

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.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
