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.
Mastering Comfort and Elegance: Our Expert Fujitsu Concealed Duct System Installation in Montreal
At AirGreen, we take pride in transforming your living space into a serene and climate-controlled haven, all while maintaining the highest standards of professionalism. Our latest project involved the meticulous installation of a Fujitsu Concealed Duct System, an 18,000 BTU powerhouse that delivers seamless heating and cooling. Situated in the bustling heart of Montreal, this system is the embodiment of efficiency and subtlety, perfect for homeowners seeking comfort without compromising aesthetics.
The Challenge: Discretion and Efficiency in a Vibrant Home
When we were approached for this project, the client had a specific set of requirements: efficient climate control that remains discreetly tucked away. They wanted a system that could handle the fluctuating weather of Montreal while keeping a minimalist and sophisticated design. Our team knew the Fujitsu RLF Concealed Duct System would be the ideal match, thanks to its slim profile and ultra-quiet operation.
Why Choose the Fujitsu RLF Concealed Duct System?
This 18,000 BTU system is more than just a heat pump; it’s a masterpiece of engineering designed to deliver optimal comfort without drawing attention to itself. With three attached 6,000 BTU outlets, it ensures a balanced and evenly distributed airflow throughout different zones. Here’s what makes this unit exceptional:
Compact Yet Potent
- Slim Duct Design: The Fujitsu RLF unit features a streamlined construction that makes it easy to conceal within walls or ceilings, perfect for spaces where every inch counts.
- Dimensions: Measuring 24.41 x 7.78 x 35.44 inches, this unit integrates effortlessly into tight spaces while maintaining robust performance.
Whisper-Quiet Operation
- Noise Level: Operating at just 29/33 dB(A), the system is so quiet you’ll hardly know it’s there, making it ideal for bedrooms, home offices, or serene living spaces.
- Sound Insulation: Special insulation features keep noise to a minimum, ensuring an environment of tranquility.
The Intricacies of the Installation
Our experienced technicians carried out the installation with great care and precision. Given the concealed duct system’s complexity, several important factors were considered:
- Custom Ductwork Integration: We designed and installed ductwork tailored to the home’s layout. This step was crucial for maintaining uniform airflow across all rooms.
- Optimized Airflow: The automatic airflow adjustment technology was calibrated to prevent cold or hot spots, guaranteeing comfort in every corner of the house.
- Piping and Refrigerant Management: The system uses R-410A refrigerant, an eco-friendly option that minimizes environmental impact. Our team expertly managed the 1/4 - 1/2 inch piping, ensuring efficiency and long-lasting performance.
Benefits of the Fujitsu RLF Concealed Duct System
Unmatched Energy Efficiency
Certified by Energy Star, this system stands out for its energy-saving capabilities. Homeowners can enjoy year-round comfort while seeing a noticeable reduction in energy bills.
- Intelligent Mode Switching: The auto changeover feature ensures that the unit automatically switches between heating and cooling, depending on the weather.
- Programmable Timer: The weekly timer allows users to set cooling or heating schedules, optimizing energy use throughout the day.
Acoustic and Environmental Excellence

- Eco-Friendly Operation: By using R-410A refrigerant, the system is designed with the planet in mind, aligning with eco-conscious values.
The Finishing Touches: Attention to Every Detail
To conclude this project, we conducted a thorough quality check, ensuring that everything from the duct connections to the airflow regulation met our high standards.

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.

Your own project, step by step
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Check the indoor module's filter.
- Clear winter debris from the outdoor unit.
- Test cooling before the heat arrives.
- Check the filter more often in peak season.
- Keep registers and returns clear.
- Watch condensate drainage near the coil.
- Change or clean the filter.
- Test heating and backup heat before the cold.
- Book periodic maintenance.
- Clear snow around the outdoor unit.
- Store nothing in front of the indoor module.
- Note any unusual noise or smell and call us.
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.
