Why is it important to have your ductwork cleaned?

Having ductwork professionally cleaned is important. A clean ductwork system will improve the indoor air quality of your premises. Dust, debris, mould and other contaminants can over time build up in the ductwork system, circulating throughout. With regular cleaning, clean air ducts reduce allergens and irritants and relieve those affected by allergies and respiratory conditions.

Not only is having a clean air duct beneficial for protecting those within your care but can enhance the efficiency of your heating, ventilation, and air conditioning system (HVAC), with regular cleaning allowing air to flow freely. This reduces the workload of your HVAC, optimising the system performance and can extend the lifespan.

Having ductwork cleaning is a proactive measure that promotes a healthier, more efficient, and comfortable indoor environment while potentially saving on energy costs and extending the life of your HVAC system.

Signs ducting requires deep cleaning

The common signs your ducts should be cleaned:

  • Visible signs of dust or debris - If you notice dust or debris coming out of your air vent system, the presence of mould on the vent covers or a need to change clogged air filters more frequently, can be a clear sign that your ducts may need cleaning.
  • Unpleasant odours - odours generated from mould or debris can create a musky aroma and can be removed through duct cleaning, leading to a fresher indoor environment.
  • Allergic reactions or respiratory issues - if you are experiencing issues with allergies or respiratory problems, dirty air ducts could be causing the issue by circulating allergens and irritants in the air. 
  • Reduced airflow - If you notice a significant reduction in airflow from your vents, it could be due to a blockage
