Indoor air pollutants and where they come from

Indoor air pollution is a growing problem. It’s a big concern for many homeowners like you. You must install, clean, and maintain your heating and cooling ducts. This helps to avoid the buildup of harmful allergens like dust, pollen and debris. Microbiological growth like mold can increase over time. These spores that can get into your home, especially in the bedrooms, kitchens, and other areas. Allergic reactions and other symptoms can occur during exposure.


There are many sources of pollutants in your home. Oil, gas, tobacco, and asbestos-containing insulation are all causes says the EPA. Pollutants include dust and allergens from household cleaning products and personal care products. Dirty heating and cooling units and outdoor sources can also be pollutants. Now that you know where the pollutants are coming from, how do you ensure your indoor air is as clean as it can be?

Have Regular Duct Cleaning Done Every 3 to 5 Years

Hiring a professional skilled in heating and cooling duct cleaning is a must. A licensed HVAC contractor does the job right the first time, every time. You should have your ducts cleaned every three to five years by a contractor who is experience in this area. Ask for references and check their background. make sure they’re licensed and have been in business for many years. Any contractor who suggests you should clean your ducts more often than that may be scamming you.

Other times to get your ducts cleaned include:

  • When you move into a new home. This is unless you have proof that the former homeowner cleaned the ducts within the past few years.
  • After building a new home or having significant construction and remodeling done. This is because drywall dust can build up within the ducts during that time.
  • 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

Why should you have your ducts cleaned often? Especially when you think about all the other household expenses you have to worry about. With your air ducts, remember that your health is at stake. You wouldn’t go longer than 3,000 miles without changing the oil in your car. Why would you neglect your ductwork? Out of sight is, unfortunately, out of mind for many homeowners. Your duct work is very important and you should treat it as a priority. After all, it delivers air to every room in your home. This is air that you breathe every second of every day you spend in your home.
Mold needs a few things to survive:
  • Moisture
  • Nutrients (dirt, dust, pet dander, cellulose construction debris)
  • Surface on which to grow
Don’t let your ducts become a playground for mold, fungi, mildew, and germs that could make you sick. Besides the health factors, efficiency is at stake here as well. Energy Star says that cleaned HVAC systems perform better and are more efficient.
