Reduce Your Energy Bill with a Ducted System: A Detailed Cost Analysis in Montréal

Maximize Comfort and Savings with a Custom HVAC Installation in Greater Montréal

At AirGreen, we’ve seen a major shift in how homeowners and building managers approach energy consumption. More and more, people are looking for high-performance HVAC solutions that are discreet and energy-efficient, capable of delivering year-round comfort while reducing their energy footprint. The ducted HVAC system, still unfamiliar to many, is one of the most efficient solutions we regularly install throughout Montréal, Laval, Longueuil, as well as the North Shore and South Shore.

What is a Ducted HVAC System?

The ducted system is based on a network of hidden ducts installed in ceilings, drop ceilings, or attics, all connected to a central indoor unit, which operates very quietly. This configuration allows for even distribution of warm or cool air in every room, without the need for multiple visible wall-mounted units.

Unlike wall-mounted units, the ducted system offers an invisible and aesthetically pleasing solution, and is ideal for full renovations or new builds. It also allows for precise room-by-room temperature control through thermostats or smart sensors.

Cost Analysis: How Much Can You Save with a Ducted System in Montréal?

Our technical team conducted a comparative study based on over 20 recent installations in Montréal, Laval, and Longueuil. Here’s a representative example:

Residential homeowner in Outremont – 2,200 sq. ft. duplex:

  • Previous system: Electric baseboards + portable AC

  • Annual electricity cost: $4,200

  • New system: FUJITSU central ducted heat pump (24,000 BTU / SEER 20)

  • Annual cost after installation: $1,950

  • Annual savings: $2,250

  • Eligible for Hydro-Québec’s LogisVert Program: $5,000 rebate

  • Return on investment: 4 to 5 years

Conclusion: While the initial investment for a ducted system is higher, it delivers significant medium-term savings, along with a major upgrade in thermal comfort.

Why Choose a Ducted System Over a Wall-Mounted One?

Criteria Wall-Mounted System Ducted System
Aesthetics Visible Invisible
Air distribution Localized Even in all rooms
Noise Low Nearly silent
Temperature control Per unit Centralized and zoned
Suitable for large spaces Limited Ideal
Maintenance Simple Professional required

The long-term benefits of ducted systems make them a smart choice for demanding homeowners or mid-to-large size buildings.

Real Installation Example by AirGreen in Rosemont–La Petite-Patrie

One of our clients, the owner of a 1950s brick triplex in Montréal, contacted us to replace his oil heating system and completely modernize his cooling and heating setup. After a full evaluation, our team installed:

  • FUJITSU KZTA36R32 ducted indoor unit (36,000 BTU, R-32)

  • Insulated flexible and rigid ducts across 2 floors

  • Discreet air grilles integrated into the interior design

Challenges Encountered:

  • Limited attic access for duct routing

Final result: A silent, efficient, invisible system with consistent comfort in every room. The client praised our proactive approach, technical precision, and professionalism on-site.

What You Need to Know Before Installing a Ducted System

Before selecting a ducted system, it’s important to:

  1. Evaluate the available space for routing ducts (between joists, in attics, or in drop ceilings).

  2. Determine the required capacity (calculated by our heat load experts).

  3. Check eligibility for available rebates, such as those from Transition Énergétique Québec or Hydro-Québec.

  4. Choose a certified installer like AirGreen, who can guarantee clean, efficient work that complies with CSA and RBQ standards.
