Signs It’s Time To Clean Your Air Ducts

A dirty duct system is the perfect home and breeding ground for rodents and insects. If you’re concerned with a potential infestation, it may be time to schedule a professional to clean the air ducts. Routinely cleaning and maintaining your air ducts will help prevent these types of infestations.

If you’ve noticed a rise in your energy bill or increased dirt and dander, it’s a sure sign it’s time for a cleaning.

Recent renovations to your condo increase the amount of dirt and debris in the home. Cleaning the air ducts after a renovation will remove the lingering pollutants in the air.

Mould and mildew are serious health hazards and another sign to schedule maintenance on your duct system. Depending on your living situation, it’s recommended to schedule a cleaning of the air ducts every six months to a year. The air quality of your home affects your health.

If you’re unsure whether the duct maintenance falls under your responsibility or if it’s covered under your condo association monthly fees, contact your condo association to confirm before scheduling service.

Professional Air Duct Cleaning

Hiring a professional to clean the air ducts ensures it’s done properly and that there are no lingering issues. They will test your system and confirm functionality while providing a professional-grade cleaning.

A professional air duct cleaner will:

Thoroughly Inspect the Air Ducts

Upon arrival, the technician will request information about your concerns to make sure all of them are addressed. Prior to cleaning the ducts, the professional will inspect the unit for proper supply and return registers, leaks, and other potential issues. The evaluation of supply and return airflow helps in determining the extent of build-up in the air ducts.

Any leaks in the HVAC system cause underperformance and should be addressed.

Access the Interior for Cleaning

Accessing the interior of the air duct requires opening the diffuser or cap of the HVAC system. This process provides a hole to be made for sufficient access for thorough cleaning. Upon completion, the hole is properly closed.

It’s not recommended for you to attempt this process yourself, and it should be left to a professional.

Break Down Contaminants

A professional will use a revolving brush and air whipping tools to loosen and detach the dirt stuck inside the ducts prior to cleaning.

The contractor will also remove settled dust from the main lines to provide a more effective end result.

A Negative Pressure Vacuum

A negative pressure vacuum eliminates the potential of inhaling polluted air from the cleaning process.

For the proper use of the vacuum, a hole is made in the duct for insertion of the vacuum. The collection device hose is set up near the air handler, and the vacuum hose is then sealed tightly in the hole. The registers are sealed and turned off, and the negative pressure vacuum is turned on — each duct is thoroughly cleaned.


Prior to cleanup, the technician will properly close the duct and re-access the HVAC unit to confirm proper functionality and air circulation.

Clean and Tidy

Once the system is confirmed to be functioning properly, the technician will clean the work area. They will provide feedback and the condition of the unit and show their work.

Additionally, cleaning the blower motor, drain pan, and evaporator coil is recommended to further improve the air quality.

The Benefits of Routine Maintenance

As mentioned earlier, dirty air ducts can affect your health and wallet.

Remember these important benefits of routine maintenance:

  • Improved air quality and fewer health hazards
  • Longevity and efficiency of your HVAC system
  • Reduction in your energy bill
  • Early detection of issues and less costly repairs
  • Eliminates odours
