ELIOS 4-Way Cassette | 18,000 BTU R454B | Greater Montreal Installation

The discreet elegance of absolute comfort: the ELIOS 4-way cassette, designed for the Quebec climate

At AirGreen , we believe that ideal indoor comfort should not come at the expense of aesthetics. It is with this in mind that we install the ELIOS 18,000 BTU 4-Way Cassette , a high-end HVAC solution, designed to combine performance, discretion and exceptional energy efficiency. Adapted to the harsh climate of Greater Montreal, this ceiling heat pump stands out for its heating power down to -25 °C , its superior energy efficiency (SEER2 of 20.7 and HSPF2 of 11.4), and its ability to provide constant, quiet and uniform comfort in every corner of the room.

A smart and invisible solution for all spaces

One of the greatest advantages of the ELIOS 4-way cassette is its recessed ceiling installation . Invisible once installed, it frees up your walls and floors, while ensuring 360° air diffusion . Whether for a condo in downtown Montreal , a residence in Laval , or a business in Longueuil , this versatile design adapts perfectly to all architectural environments.

Our RBQ #5645-9605-01 certified technicians frequently install this model in professional offices , restaurants , medical clinics , and even high-end residential spaces where aesthetics and performance must coexist without compromise.

Exceptional thermal performance down to -25°C

Montreal's winters spare no one—but the ELIOS 4-Way Cassette rises to the challenge. Thanks to its rotary compressor with inverter technology and its new-generation R-454B refrigerant , it maintains optimal performance even in extreme cold. With a heating capacity of 18,000 BTU/h , it can efficiently heat large spaces while consuming minimal energy.

Its energy efficiency translates into:

• SEER2: 20.7 (cooling),

• EER2: 12.5 ,

• HSPF2: 11.4 (heating),

• CPSC2-5: 8.5 (region V) .

These figures are not just technical values: they mean a tangible reduction in electricity costs , better thermal comfort , and a reduced carbon footprint for every household or business in Greater Montreal.

Technology designed for comfort and peace of mind

The ELIOS 4-way cassette also stands out for its quiet operation . At just 24.5 dB(A) in low mode, it completely disappears from your daily life. Its adjustable airflow (up to 760 m³/h) allows you to adapt the ventilation to every need — whether it's a light summer refreshment or rapid heating in the heart of winter.

Additionally, this unit incorporates a built-in refrigerant leak sensor , an exclusive safety innovation that continuously monitors the refrigeration circuit. In the event of an anomaly, the system automatically shuts down and sends a service alert, ensuring peace of mind and permanent safety .

Compact design and installation flexibility

The indoor unit (22.44 × 22.44 × 9.65 in) fits perfectly into standard ceiling tiles or residential drywall . 1/4” and 1/2” refrigerant lines make it easy to connect to the compact ESHEA18C2AN1 outdoor unit (35.04 × 13.46 × 26.50 in), for a discreet, seamless and professional look .

This flexibility allows our AirGreen installers to create tailor-made configurations , particularly in:

• Commercial spaces in Laval requiring balanced airflow,

• Single-family homes on the North Shore wishing to reduce clutter,

• Montreal condos where every inch of space counts.
