ELIOS 1-Way Cassette | 18,000 BTU R454B | Greater Montreal Installation

The invisible elegance of comfort by AirGreen

At AirGreen , we believe that comfort should never compromise the aesthetics of your space. This is exactly what the ELIOS 18,000 BTU 1-Way Cassette achieves, a high-end heat pump designed to deliver exceptional performance, quiet operation, and seamless architectural integration. Designed for homes, businesses, and offices in Greater Montreal , this unit combines discretion, efficiency, and durability —everything our most demanding customers are looking for.

A cassette designed to fit perfectly

One of the biggest advantages of the ELIOS 1-Way Cassette is its absolute discretion . Its compact design (just 13.9 inches high) allows it to fit easily between joists or engineered beams , making it an ideal choice for renovations, modern condos and spaces with limited ceilings.

Unlike visible wall units, the 1-way cassette is installed directly in the ceiling, revealing only a minimalist grille ensuring directional and uniform air distribution. The result: consistent comfort , without compromising on style or space.

Power and performance adapted to the Quebec climate

Designed for the extreme conditions of Quebec , the ELIOS 18,000 BTU 1-Way Cassette excels in both air conditioning and heating:

• Cooling Capacity: 18,000 BTU (range 4,000 to 18,800 BTU/h)

• Heating Capacity: 18,000 BTU (range 7,600 to 22,800 BTU/h)

• Exceptional energy efficiency:

  • SEER2: 22.2

  • EER2: 12.5

  • HSPF2: 9.0

  • COP at 8.3°C: 3.30

• Heating performance down to -25°C

• New generation refrigerant R-454B : more environmentally friendly and efficient

This data confirms that it is an ENERGY STAR® cold climate solution , capable of providing stable and efficient heat even in the heart of Montreal's winter. In summer, it ensures rapid and even cooling while minimizing electricity consumption thanks to its continuously modulating inverter technology.

Quiet, comfortable and intelligent control

Comfort isn't just about temperature—it's also about noise . Thanks to advanced acoustic design, the ELIOS 1-Way Cassette boasts a minimal indoor noise level of 24 dB(A) at low speed, the equivalent of a whisper. The outdoor unit, meanwhile, operates at 57.5 dB(A) , keeping urban or residential environments quiet.

Control is also simplified:

• Wired or wireless remote control (optional)

• Smart Wi-Fi (optional dongle) for control via mobile app

• Programmable mode to optimize cycles according to your schedule

With AirGreen, you maintain complete control over your comfort, wherever you are.

An installation by AirGreen: expertise and precision

Each ELIOS cassette installation carried out by AirGreen is a custom project. Our RBQ-certified refrigeration technicians study the layout of the site to optimize air distribution and ensure maximum energy efficiency.

In a recent installation in Laval , for example, our team integrated an ELIOS 18,000 BTU 1-Way Cassette into a suspended ceiling office. The goal: to maximize comfort without cluttering the walls. Thanks to its small footprint and directional diffusion , the entire room now benefits from uniform comfort , while maintaining optimal energy efficiency.

Our customers often highlight the system's discretion and the thermal stability they feel from the first hours of use.

Safety, innovation and longevity

Every detail of the ELIOS system has been designed for safety and durability .
The unit incorporates intelligent refrigerant leak detection that monitors the system 24 hours a day. In the event of an anomaly, the compressor automatically stops, air circulation continues, and a service alert is transmitted. This gives you a secure, modern, and environmentally friendly system.

The R-454B refrigerant used by the e-Match series replaces older gases with high global warming potential. It ensures high energy efficiency while significantly reducing its environmental impact.
