The Importance of Keeping Air Ducts Clean

Jul 20, 2017

As a homeowner, you probably already know the importance of getting regular maintenance for your air conditioning system.  When Intagas checks your central air unit, we also clean all working parts, which extends its life and helps reduce your utility bills. Regularly changing the air filter is important too as a dirty filter impedes airflow and makes your air conditioner work harder.

Air ducts that are neglected for a long time can also have a negative effect on your air conditioning system. Not only can they develop leaks, which cause your air conditioner to run inefficiently, dust, dirt, mold, mildew and more can accumulate on the surfaces over time.  Dirty ducts make your system work harder in the same way that dirty air conditioning components do.

How Often Should I Clean My Air Ducts?

Unlike preventive maintenance, which Intagas recommends annually, there is no rule on how often you should have air ducts cleaned in your Brisbane home. Some industry professionals recommend that you should only have ducts cleaned if visible mold growth is present or if you have an infestation of insects or rodents. However, the National Air Duct Cleaners Association (NADCA), an American industry organisation that has member companies in Australia, recommends cleaning every three to five years.

What should you do? The answer is, it depends. If you see a lot of dirt when looking into the ducts, that’s a good sign, as well as seeing a cloud of dust when you change the air filter. Otherwise, frequency depends on your individual situation. If you have allergies or respiratory problems, you will need to clean air ducts more frequently to alleviate symptoms. Brisbane’s humid, subtropical climate can also make ducts prone to mold, which also necessitates more frequent cleaning.

Other times you should clean air ducts include:

  • When you move into a new home, unless you know that the previous owner recently serviced the air ducts
  • After building a new home or renovating an existing residence as construction spreads debris through the ducts
  • You have pets that shed

Keeping Your Ducts Clean

Clean your home frequently with a vacuum that uses a HEPA filter. Change the air conditioner filter frequently and use the highest quality filter recommended by the manufacturer. If you have a dehumidifier, make sure it is on during hot weather. Remember you can always ask your Intagas technician to quickly inspect ducts to see if a thorough cleaning is needed.
