Air Duct Cleaning and Your Health

Air Duct Cleaning and Your Health

Did you know that the air in your home circulates through your HVAC system 5-7 times a day? If your duct work is filled with mold, fungi, dust and/or other contaminants, then all that dirt, grime and bacteria is also circulated through your home 5-7 times a day. In fact studies have shown that indoor air can be up to 70 times more pollutant than outdoor air.

Dirt, mold and other contaminants in your HVAC system can exasperate existing health conditions of your family living in the house. Respiratory problems such as asthma attacks can be induced by contaminants in duct work such as mold, dust, etc. that you are breathing in. These same culprits can cause inflammation in your nasal passages when you breath them in leading to continually sinus problems. Lastly, dirty duct work and vents can cause allergic reactions such as sneezing when dust, pollen and other contaminants are present; this might be especially noticeable during the Spring season.

Duct Cleaning Services

A vent cleaning and air duct cleaning can help alleviate airborne illnesses as well as reduce mold growth, and remove unwanted odors from your heating and cooling system. On average, we recommend that you get your duct work cleaned every 5-7 years. However, if you meet any criteria below you should consider scheduling an air duct cleaning more often if you:

  • Have done a renovation/remodel in your home
  • Have pets in the home.
  • Mold is visible in your duct work.
  • Someone in the home smokes.
  • Someone in the home suffers from airborne illnesses.
  • You notice more dust, pet hair, dirt and other contaminants in your home

In addition to improving your health, vent cleaning and air duct cleaning can have other very important benefits to your system and your wallet. By cleaning out the dust and debris in your duct work, the air in your system will flow more freely, which improves your system efficiency. A more efficient system means lower utility bills and more money that stays in your wallet. Less wear and tear on your system also gives it a longer equipment lifespan.

  • Sarah Floyd Hi, you guys have worked on our furnace a while back. Now, I think my ducts need cleaning. I keep smelling dust and can't find where it's coming from. I didn't have any issues when the air conditioning would come on. My house is a double wide mobile, forced air furnace. The house is 1148sf. Would you be able to tell me kind of a ballpark figure for cleaning the air ducts? Thanks so much, Sarah Floyd Fern Prairie Reply
