Air ducts eventually become dirty. Every day, as the air is circulated around the house multiple times, filth, dust, and grime are left behind and build up on the walls of the passageway. The effects this accumulation can have on our health are worth knowing. Our health and the health of everyone else residing in our home depend on the cleanliness of these air ducts.

Long story short, for the sake of our family, we should have duct cleaning of the ventilation system in our house done by specialists every three to five years. We need people who can do the job of scrubbing and disinfecting the pathway of our air filtration in the home. First, let’s talk about what may be lodged in our air ducts that can affect the quality of the air we breathe inside the house.

The Gunk in our Vents

No matter how clean your home is, your air ducts will gather dirt, dust, and debris over time, resulting in what could be a sticky mess. If this gunk isn’t removed, it can accumulate in your ventilation system and spew polluted air. If you have the tools needed to fix the problem, then you’re good. Otherwise, it’s best to call a professional.

Here are the 5 signs to watch out for:

  1. Dirty ventilation covers
  2. Blocked air filters
  3. Mold and mildew
  4. Rodents and insects
  5. A smelly duct.

There’s no need for me to expound on each of them, as they’re all self-explanatory anyway.

Dirty Ducts and Health Issues

So many of us now rely on online technology for commerce, education, earning a living, and leisure. Because of this, there’s no need to go out anymore. Unfortunately, according to the experts, indoor pollution levels can be up to 10 times higher than outdoor levels, and this can lead to health problems for all of us. Today, we’ll talk about five major health issues that are usually caused by filthy ducts.


If we spend the bulk of our time indoors and suffer from persistent allergies, unclean ducting may be to blame. Bacterial growths, mold spores, and dust mites inside our ventilation system cause allergic reactions.


Dander, pollen, dust, mold, and microbial activity in your air ducts might cause asthma attacks. If you observe your asthma getting worse when you’re at home, it may be rooted in poor indoor air quality.

Respiratory Issues

Thousands of hazardous minute particles and germs could enter our bodies with each breath. Our lungs will react if we are sensitive to them, and many of us will suffer from coughing, nasal congestion, and a sore throat.


Mold might impair one’s ability to think. Adults and children have been diagnosed with such problems due to long-term exposure to it. This can lead to laziness, memory loss, mood swings, or insomnia.

Skin Issues

More than respiratory problems, dirty ducts can also cause skin conditions like dermatitis, rashes, hives, irritation, or just plain itching. Mold and mildew are known to cause them.

Fresh Breeze All Day

Homeowners only need to think about air duct cleaning when the five clues to guard against have become obvious:

  1. Dirty ventilation covers
  2. Blocked filters
  3. Evidence of mold and mildew
  4. Rodents and insects
  5. A smelly passageway

This should happen every three to five years.
