How Does Duct Cleaning Work?


According to the National Air Duct Cleaning Association’s standardized methods, negative air pressure is the proper cleaning method. Before anything else is done, the technician will inspect your ducts for leaks that could affect the cleaning process.

Once they’ve confirmed your ducts are properly sealed, they’ll connect a vacuum toward the center of the system, near the air handler. They then seal each vent to create a strong vacuum in the system.

Then they go room by room and unseal one vent at a time, and clean from each vent. At each vent, the technician will use a combination of compressed air and special brushes designed for ducts. This agitates and loosens the dust and dirt from within the ducts so that the vacuum can remove it.

Duct Cleaning FAQs

Do I Need Duct Cleaning Every Year?

If you vacuum and dust regularly and get routine HVAC maintenance, you likely don’t need annual duct cleaning. Rather, the recommendation is every three to five years if you have average air quality. However, if you complete a major project that creates a lot of dust or otherwise have poor air quality, you may need more frequent duct cleaning.

Does Duct Cleaning Use Chemicals?

Duct cleaning does not usually use chemicals for the cleaning process. However, your particular situation may have special needs to provide the appropriate level of cleaning. If your ducts have microbial growth started, you may want to opt for a mild, non-toxic antimicrobial cleaner.

How Long Does Duct Cleaning Take?

The amount of time it’ll take to complete your duct cleaning depends on the size of your system, age of your home, and other air quality factors. On average, plan for the process to take between two and four hours. Be wary of companies that promise to have it done more quickly, being they will likely not give proper attention to each vent.

Signs Your Ducts Need Cleaning

You’ll notice several signs when your ducts need cleaning. The longer you let these signs go, the more impact you’ll notice on your system, so tend to it quickly.

Dust Around Your Vents:
When contaminants start building up in your ducts, the air moving through the system will pick up some particles and carry them out in the air. This usually leads to additional dust around your home, particularly around your vents.

Musty Odors:
Dust and dirt buildup in your vents creates the perfect place to trap moisture. That moisture then leads to the development of biological contaminants, leading to a musty smell as your system runs. In addition to cleaning your ducts, make sure you’re keeping your household humidity between the recommended 30% to 50%.

Unusual Sounds:
Popping and flexing sounds from your ducts may mean several things. In some cases, the temperature difference between the ducts and the conditioned air may cause the flexing. However, it may also mean there are obstructions within the ducts, causing airflow restrictions and unusual pressure. Have a professional technician troubleshoot any of these sounds to uncover their source of potential problems.

Inconsistent Heating or Cooling:
Most ducts don’t collect contaminants uniformly throughout the system. This leads to airflow restrictions in some areas, causing inconsistent temperatures throughout your home. If you notice this, start by making sure your vents are open to allow air to flow throughout the system properly. If that doesn’t work, it may be time to try a Clarksville duct cleaning service.

Frequent Dirty Air Filters:
Your air filters will eventually clog and need replacing. In a home with average air quality, you’ll need to replace the filter about every one to three months, for the common 1- and 2-inch filter. Dirty ductwork will require more frequent changes, sometimes in as little as a month or less.
