Pet hair often collects near returns
Homes with pets can load return grilles and filters faster. Some hair and dust can settle inside accessible duct sections, especially if filters were not changed often.
Odours can have more than one source
Duct cleaning may help remove debris from the airflow path, but odours can also come from carpets, furniture, moisture, filters and the furnace cabinet.
When it makes sense
Consider service after moving into a pet-friendly resale home, after renovation work, or before replacing HVAC equipment.
