Average Ductwork Cleaning Cost in Toronto & GTA (2026)

Most GTA homeowners pay around $300–$450 for a complete residential duct cleaning service.

What Impacts Duct Cleaning Cost?

Many companies advertise low starting prices, but several factors determine the final quote.

1. Number of Supply & Return Vents

The biggest pricing factor is usually vent count.

More vents require:

• Additional cleaning time
• More vacuum extraction
• Extra technician labor

Homes with finished basements often have significantly more duct runs.

2. Size of the Home

Larger homes generally contain:

• Longer duct systems
• More return lines
• Multiple HVAC zones

A 3,500 sq ft detached home will cost considerably more than a condo.

3. Furnace & HVAC Condition

Dirty furnaces increase labor requirements.

Some companies charge extra for:

• Blower cleaning
• Furnace vacuuming
• Main trunk cleaning
• Coil cleaning

Always ask what’s included.

4. Renovation Debris

Post-renovation duct systems commonly contain:

• Drywall dust
• Wood particles
• Construction debris
• Insulation dust

These jobs usually require deeper extraction methods.

5. Pets & Allergens

Homes with pets often accumulate:

• Fur
• Hair
• Dander
• Odors

This can increase service time and cleaning intensity.
