Duct Odour Cleaning: Fresh Air for a Healthier Home
If your home or office air smells musty, it might be time for a thorough duct odour cleaning. Over time, dust, mold, bacteria, and pet dander can build up inside your air ducts, causing unpleasant smells and potentially affecting your health. In this article, we’ll explain why bad odours develop, how to clean your ducts, and tips to keep the air in your space smelling fresh.
Why Duct Odours Occur
Understanding the source of these smells is the first step toward solving the problem. Common causes include:
- Moisture buildup that leads to mold and mildew growth
- Accumulated dust and dirt that trap bacteria
- Pollen, pet hair, and dander collecting over time
- Dead rodents or insects nesting inside ductwork
- Lingering cooking smells or tobacco smoke
Signs You Need Duct Odour Cleaning
Not sure if it’s time for a cleaning? Watch for these warning signs:
- A persistent musty or sour smell when the HVAC runs
- Visible dust falling from vents
- Allergy symptoms like sneezing or coughing that worsen indoors
- Uneven heating or cooling caused by clogged ducts
DIY vs. Professional Cleaning
Deciding whether to tackle duct odour cleaning yourself or call a professional depends on your budget, tools, and comfort level.
- DIY Cleaning: Basic vacuuming of vent covers and accessible ductwork. Use a brush attachment and mild detergent.
- Professional Cleaning: Technicians use high-powered vacuums, rotating brushes, and EPA-approved deodorizers. They can also inspect for mold and structural damage.
