Indoor air pollutants and where they come from

Indoor air pollution is a growing problem that’s concerning to many homeowners just like you. Your heating and cooling ducts must be properly installed, cleaned and maintained so as to avoid the buildup of harmful allergens such as dust, pollen and other debris. Microbiological growth like mold can increase the prevalence of the growth of these spores that can get released into your home, invading the safety of your bedrooms, kitchens and other living areas. Allergic reactions and other symptoms can occur during exposure.


There are many sources of pollutants in your home, from combustion sources such as oil and gas, to tobacco products and asbestos-containing insulation, says the EPA. In addition, pollutants can include dust, allergens from household cleaning products, personal care products, dirty heating and cooling devices, and outdoor sources such as pesticides. Now that you know where the pollutants are coming from, how do you ensure your indoor air is as clean as it can be?

Regular Duct Cleaning Should Be Done Every 3 to 5 Years

Hiring a professional skilled in heating and cooling duct cleaning is a must. This ensures a licensed HVAC contractor does the job correctly. It’s recommended that you have your ducts cleaned every three to five years by a contractor who has experience in this realm. Ask for references and check their background to ensure they’re licensed and have been in business for many years. Any contractor who suggests your ducts should be cleaned more often than that may be scamming you.

Other times to get your ducts cleaned include:

  • When you move into a new home, unless you have proof that the former homeowner got the ducts cleaned within the past few years.
  • After building a new home or having significant construction and remodeling done to your existing one. This is because drywall dust can build up within the ducts during that time period.
  • If you have pets. This is because pets tend to shed a lot of fur and dander, which can also cause a build up in your ducts.
  • If you can’t remember the last time you got your ducts cleaned! If you suspect it’s been at least five years, call a qualified HVAC professional.
  • If you or your family members suffer from allergies or asthma.
  • If you get frequent headaches or experience itchy eyes and nausea while at home.

Why Duct Cleaning is Necessary

If you’re wondering why you should have your ducts cleaned regularly, what with all the other household expenses you have to worry about, consider that your health is at stake. You wouldn’t go longer than 3,000 miles without changing the oil in your car, so why would you neglect your ductwork? Out of sight is, unfortunately, out of mind for many homeowners. However, your duct work is very important and should therefore be treated as a priority. After all, it delivers air to every room in your home — air that you breathe every second of every day you spend in your home.

Mold needs a few things in order to survive:

  • Moisture
  • Nutrients (dirt, dust, pet dander, cellulose construction debris)
  • Surface on which to grow

Don’t let your ductwork become a playground for mold, fungi, mildew and harmful germs that could be making you and your kids sick. In addition to health factors, efficiency is at stake here as well. Energy Star says that properly cleaned HVAC systems perform at a higher and more efficient level.
