If they are not cleaned regularly, dirty ducts can potentially recirculate germs and infections. Whichever way you look at it, it poses a risk to indoor air quality. With regards to Covid-19, the public perception has been leaning towards the opinion that the virus is transmitted only through direct contact, such as through droplets and from surface contact. However, recent evidence has shown dirty ventilation systems may be behind transmission, too.

Besides regular air duct cleaning, replacement of filters and sanitizing common touch points look set to be effective ways of combating Covid-19 spread.

Signs of dirty/clogged filters and ducts

There are a certain number of signs that the air duct, filters and engine of a ventilation system are dirty. If your HVAC unit is manifesting any of the symptoms mentioned below, it could become direct evidence of dust and debris clogging the system.

  • Excessive noise during operation
  • Particles or dust being blown out of ducts
  • Reduced efficiency (greater than normal heat, energy consumption)
  • Mould accumulation around the premises
  • People coughing or complaining of nasal congestion

How regular air duct cleaning can improve indoor air quality

Indoor air quality can affect the health and wellness of homeowners. There is a chance that germs blowing around the premises, and excessive dust not being caught by the filters can lead to asthma and allergies. Systematic cleaning of the ducts makes the place safer and much more comfortable for owners.

  • Ease respiratory illnesses due to dust and debris elimination
  • Clean dust and mould spore build-up deep inside the HVAC unit
  • Reduce the risk of bacterial and viral transmission

Note: Air duct cleaning cannot stop the spread of Covid-19, it can help reduce the risk of airborne transmission if such exists. Please continue to follow guidelines: wash your hands, sanitize your surroundings regularly and practice physical distancing.

What causes dirty air vents?

Dust, lint, hair, pet dander and flakes of skin get caught on fine dust filters and accumulate along the length of the air ducts. Over the course of  time, they can build layers of matted surface that become a breeding ground for dust mites, allergies and infections.

Also when you do a renovation in your home,  there is always a lot of dust & dirt that gets into the vents, which is not great for breathing.

How often should you clean your HVAC ducts?

Specialists recommend cleaning the air ducts once every 3 to 5 years. However, in light of the Covid-19 situation, a more frequent professional cleaning is advisable. There is no precise formula for how often ducts have to be cleaned, so you should take into account your indoor environment and need to maintain the health of occupants.
