Exclusive Comparison: Ceiling Cassette vs. Floor-Ceiling Unit for Commercial Spaces in Montréal

Two Discreet and Powerful HVAC Solutions for Commercial Spaces in Montréal

In a market as dynamic and demanding as Montréal, commercial spaces—whether restaurants, offices, hair salons, or boutiques—must constantly tackle a critical challenge: delivering optimal thermal comfort while maximizing the available space. That’s where two types of indoor HVAC units truly stand out for their performance and discretion: the ceiling cassette and the floor-ceiling unit. At AirGreen, we’ve installed and maintained these systems in dozens of businesses across Montréal, Laval, Longueuil, the North Shore, and the South Shore, and we’re bringing you a real-world, expert comparison based on our field experience.

Why Are These Two Models Ideal for Commercial Use?

Adaptability to Layout Constraints

In commercial environments, every square foot counts. Ceiling cassettes are installed in drop ceilings, completely freeing up wall and floor space. On the other hand, floor-ceiling units are perfect when there’s no suspended ceiling available or when the building’s architecture limits options (historic buildings in Plateau-Mont-Royal, commercial basements, etc.).

Performance and Air Distribution

Both systems offer even air distribution, but they do so differently:

  • Ceiling cassette: 360° air flow, ideal for open-concept rooms.

  • Floor-ceiling unit: installed high or low on a wall, with directional airflow, perfect for longer or partitioned spaces.

Case Study: Two Recent Installations by AirGreen in Montréal

Ceiling Cassette in a Wellness Center in Rosemont

We recently installed a Fujitsu R-32 ceiling cassette with 24,000 BTU in a wellness center located in Rosemont–La Petite-Patrie. The challenge: integrate an invisible solution to maintain the establishment’s zen aesthetic. Thanks to the available space in the drop ceiling and our custom air distribution design, the installation was completed in two days with no service interruption. The unit is eligible for a $1,860 LogisVert rebate.

Floor-Ceiling Unit in a Restaurant in Old Montréal

Different setting, different solution: in a restaurant with vaulted stone ceilings in Old Montréal, we installed a Gree floor-ceiling unit with 18,000 BTU. With no drop ceiling available, the unit was mounted mid-height on a load-bearing wall, ensuring direct airflow into the dining area. The system blends perfectly with the venue’s rustic design and led to a 28% reduction in annual energy bills.

The Advantages of Each System Depending on the Commercial Setting

Criteria Ceiling Cassette Floor-Ceiling Unit
Aesthetics Invisible, built into the ceiling Visible but compact
Airflow 360°, multidirectional Directional, adjustable
Installation Requires a drop ceiling Flexible wall/ceiling mounting
HVAC Maintenance Ceiling access via hatch Direct and simple access
Best suited for Offices, retail stores, clinics Restaurants, salons, spaces without drop ceilings

Technical Elements to Consider Before Choosing

Available Space and Building Structure

Before recommending any unit, we assess:

  • Ceiling height

  • Presence or absence of drop ceiling

  • Existing thermal insulation

  • Furniture and lighting layout

Required Capacity

BTU requirements vary based on surface area, sun exposure, and the number of occupants. A custom thermal analysis is always performed by our certified technicians.

Noise Level

Both systems are extremely quiet, but in businesses where ambiance is essential (spa, waiting room, yoga studio), we prioritize models with inverter technology and acoustic levels under 25 dB.

Rebates Available in Montréal, Laval, and Surrounding Areas

At AirGreen, we help our clients maximize their return on investment through available provincial and municipal rebate programs:

  • Hydro-Québec’s LogisVert Program

  • The Québec Government’s Chauffez Vert Program

Mistakes to Avoid When Choosing and Installing

  • Failing to properly assess thermal needs (risk of oversizing)

  • Choosing a cassette for a space without a drop ceiling (common mistake)

  • Overlooking regular HVAC maintenance access

  • Installing a floor-ceiling unit without protection in high-traffic areas
