Are the air ducts in your house dirty? Dirty air ducts can result in the spread of dirty air in all of the home’s living spaces and other indoor areas. Surprisingly, there could be a chance that the level of indoor air pollution may exceed that of outdoor pollution. Whether it is home or office, people spend majority of their dayssitting indoors, which means they could be exposed to a number of health problems. Let us take a look at how your dirty ductwork can play havoc with your health and life.


Dust, pollen and mold spores are among the common particles that are harboured by dirty air ducts. When a person in the house is allergic to these, the unclean air ducts tend to set off and lengthen the allergy attacks. Some people even complain that their allergy symptoms are worse when at home and subside when they are out. Their ducts could be a likely factor contributing to such symptoms.

Sinus Problems

The dust, dirt and debris trapped in the air ducts get blown into your house with every cycle run by the Heating, Ventilation and Air Conditioning (HVAC)system. This implies that with every breath you take, these dirty particles expelled into the air enter your (and your family’s) nasal passages. These particles work their way into the sinuses, triggering inflammation that can lead to sinus infections. Sinus infection can be a painful condition and may have complications when left untreated.


For those with asthma condition,an attack may be triggered due to their exposure to pollen, mold, dust and other contaminants that are largely located in dirty ductwork. If your asthma symptoms get worse when at home, filthy air ducts could be a reason.

Respiratory Infections

Along with viruses andallergens, your dirty air ducts may even hoard bacteria and fungi. So each time the air passes through the HVAC system, a part of these germs can blow out and enter your living areas. You can get sick due to respiratory infections more frequently than expected.

To counter all the negative impact of dirty air ducts, regular duct cleaning is suggested. Frequent air duct cleaning will prevent health problems by giving out fresh air to breathe. It will also lower your monthly energy bills.
