Indoor air quality greatly affects the comfort of your home. When your home is surrounded by dust particles, pollen, mold spores, and insect dropping, it can badly harm your health. Therefore, your air duct needs to be cleaned regularly to improve the air quality of your home. 

We have covered all the major signs when your duct will need cleaning. Have a look below!

  • Air Duct is Clogged with Debris and Dust 

When there is a presence of small dust particles, and you need the HVAC system to start running, it is clear that your duct is clogged and needs cleaning. In some cases, when you switch on the heating and cooling system, many released particles are not visible to the human eye. Therefore, your air duct indicates dusty air registers. 

  • Air Filters Become Clogged

If the heating and cooling system filters must be swapped repeatedly, it indicates a huge problem. If you change your filters periodically and they are still getting clogged after a few days of replacing them, you should examine your duct; they might need a cleaning process. 

It would be best to change your filter once in three months because, during the seasonal months, air filters are more likely to trap dust particles, debris, and other airborne pollutants that ultimately affect the indoor air quality. 

  • Bad Smell From Ducts

When you start noticing an unpleasant smell from your air duct, you should consider cleaning because it indicates the sign of debris in the duct system. All air registers need to be approached to sniff well to confirm these suspicions. You can also call a technician to inspect the air duct for anything that could give off a foul odor.

  • Insects and Rodents have Infested the Air Ducts

As time passes, many insects, rodents, and other victims make their way into the duct system, leaving behind bacteria. To prevent your air duct from these infestations, you need to clean it. If air duct cleaning is not done, insect dropping, vermin dander, bacteria and viruses will cause many health diseases. 

  • Presence of Mold in the HVAC system

Mildew or mold either inside or outside HVAC system may spread allergies and respiratory diseases. If you spot mold and mildew in the air conditioning unit or vent covers, take quick action. Besides cleaning air ducts, you may also invest in home humidifiers as mold and mildew often grow in the wet area. 

  • Ductwork is Producing Strange Noises

If you have an HVAC system, you must be aware of the system’s operational sounds. Sometimes it is difficult to distinguish between the noises. So, if you hear a kind of general motor sound, it indicates some serious problems. 

People who know how important the duct cleaning keep them always cleaned to ensure good indoor air quality. To keep your duct out of any problems, inspect the above signs and get your air duct cleaned as soon as possible!
