Let's Start With How Air Moves Inside Your Home

  • HVAC (heating/ventilation/air conditions) systems move air in and around, which means they will almost certainly bring in dust, debris, and dirt.

  • Over time, the ducts through which the air circulates will accumulate layers upon layers of built-up dirt and dust, pollen and mold spores, and even insects and rodent droppings.  

  • Humid environments can facilitate mold growth in your air duct system, particularly if air conditioning has been shut off for an extended period and the air in the home has been allowed to warm.

If any of your family members are experiencing unusual or unexplained symptoms or illnesses, your home’s environment could be the issue.

There are consequences to having a less-than-clean environment, including:

  • Nasal congestion
  • Allergies
  • Fatigue
  • And many more health issues (You should discuss any of these situations with your doctor)

Debris Build-Up In Your Ducts Will Affect Your Air Quality & Your Health, Damage Your HVAC System's Efficiency & Make a Great Nesting Place for Rodents, Insects & Mold

The EPA has published guidance on identifying possible indoor air quality problems related to ducts that are not as clean as they should be.

As per the EPA, there are several key signs that your air ducts need a thorough cleaning, including:

  • Mold growing inside the air ducts
  • The infestation of small unwanted pests and insects in the air ducts
  • If the air ducts are clogged with dust and other debris

How Uncleaned Air Ducts Affect Your Health and Overall Cleanliness

Health Issues:

  • They can decrease the air quality of your home environment. Cleaning air ducts can improve the overall health of all your family members. Medical research shows that patients suffering from pulmonary health issues improved when air ducts were cleaned frequently.

  • Frequently, allergies, sore throats, colds, and coughing can be caused or worsened by poor air quality caused by allergens and other bacteria in uncleaned ducts.

  • People with asthma and other allergies can be particularly affected, especially children, the elderly, and newborns, who are very sensitive to air quality issues.

  • Pet dander, dust, pollen, and other allergens can build up in the ducts and then be blown throughout the home.

  • There is evidence that contaminated air can speed up the aging process.

Unwanted Pests:

  • Rodents and insects can find a home where you DON’T want.  They often carry disease, bite, enter your home, and even eat food.


  • Mildew and mold in your air ducts can spread a musty odor in your home.

Decreased Efficiency of Your HVAC (Heating Ventilation and Air Conditioning) System:

  • Dirt and other debris can hinder the efficient functioning of the HVAC equipment.

Dust That Never Goes Away:   

  • One key sign that the air ducts need cleaning is the reappearance of dust on furniture and other items in your home right after you have dusted.  When the ducts are dirty, they will deposit new dust (and allergens) even on the same day that dusting occurs.

Don’t take the risk of not cleaning your air ducts.  Their cleanliness is critical to having a safe and clean home environment.   Contact Air Duct Cleaning & Radon Co. and schedule an inspection TODAY!
