For the average home, we recommend a professional duct cleaning every 3 to 5 years. However, you may want to consider it more frequently (every 2 to 3 years) if you have pets that shed, family members with respiratory sensitivities, or have recently completed major renovations.

The primary benefit is improved indoor air quality. We remove years of accumulated dust, pet dander, pollen, and other allergens, which can provide significant relief for family members with allergies or asthma. A clean system also allows your furnace and AC to run more efficiently, which can lead to lower energy bills and a longer lifespan for your HVAC unit.

You might need a duct cleaning if you notice excessive dust settling on your furniture shortly after cleaning, if there are musty or stale odours coming from your vents when the HVAC system turns on, or if you can see visible dust and debris built up inside your supply vents. It’s also highly recommended after any significant home renovation.

Burning smells often indicate trapped debris or overheating components in your HVAC system. Learn more on our duct cleaning page.
