The Importance of Air Duct Cleaning

Copy Writer • Mar 06, 2019

Air ducts are like the lungs of your home, supplying your HVAC system with a steady stream of fresh air. With so much dust, pollen, mold, and other harmful particles floating in your indoor air, your ductwork can quickly become a home for dirt. Professional air duct cleaning can keep harmful pollutants from circulating and settling in your ductwork.



What is air duct cleaning?

Your technician will inspect the system to make sure there’s no asbestos-containing materials, as those materials require specialized procedures to disturb or remove. They may cut out small holes in the ductwork to get inside. Using vacuum equipment and bristled brushes, your technician will dislodge and draw out particles and dust. Then, they’ll seal and re-insulate holes. Make sure to research and hire a qualified contractor with the resources and expertise to clean your air ducts safely. If not properly cleaned, you could face problems like damaged HVAC components or holes that have not been tightly sealed, compromising an airtight system.


How often should I schedule air duct cleaning?

According to the National Air Duct Cleaners Association (NADCA), air pollutants like dander, dust, and chemicals are re-circulated in your home five to seven times a day, on average. You should have your air ducts cleaned every three to five years, or more, depending on your lifestyle. In a home with pets, cigarette or cigar smoke, water damage, or renovation projects underway, more pollutants may be circulating. Schedule duct cleaning service if


  • You’re unsure whether previous homeowners cleaned the air ducts in your current residence.
  • There’s mold growth on visible parts inside your ducts or other heating system components.
  • Your ducts are infested with vermin like rodents or insects.
  • Your supply registers spew out dust when your HVAC system turns on.
  • Your family is experiencing unusual or unexplained respiratory problems (allergies, asthma, sore throat, etc.).


How do I keep my ducts clean on a daily basis?

Follow these tips from the pros:


  • To prevent dirt from getting into your system, use a high efficiency, manufacturer-recommended air filter for your HVAC system and change it regularly, especially if they clog frequently. When installing, make sure that air cannot get through gaps around the filter holder/frame.
  • When you schedule your regular HVAC maintenance service, ask your provider to clean cooling coils and drain pans.
  • If you are having renovations or construction work done, seal off supply and return registers throughout your home and don’t turn on your HVAC system until you’ve cleaned up the dust.
  • Vacuum and dust frequently.
