The role of Heating, Ventilation and Air Conditioning (HVAC) systems in controlling the transmission of infection should be considered an important part of a broader combined infection control strategy in buildings.

Take control with the following actions:
  • Immediate cleaning / disinfection of indoor heat exchange coils (this will ensure correct and efficient operation for your HVAC system can be achieved) using approved methods and chemicals.
  • Duct cleaning to reduce the build-up of dust and associated microorganisms which can have an adverse effect on the health of your building’s occupants.
  • New air filters should be replaced as scheduled or more often as required. Recommend upgrading or replacing the filter media to F7 – F9 grades, subject to fan capacity limitations and system design.
  • Condensate drain cleaning to ensure that drains are free flowing and not pooling in the mixing chamber.
  • A full service and maintenance operating check. Increase maintenance frequency pending usage.

HVAC is a vital consideration for building operators in our response to the Coronavirus (COVID-19) pandemic. A well-controlled indoor environment can have a significant role in reducing the spread of disease as well as maintaining our personal immune defences. Studies show that optimal conditions relating to indoor air humidity and the rate of air exchange can reduce the transmission of flu and other viruses*.

Beaver Williams staff have been trained to take all possible precautions to minimise the spread of COVID-19. We are up to date with the latest information being provided by the Department of Health.

Beaver Williams have a large team of service and maintenance experts working across the Sydney metropolitan area and NSW. We have decades of experience and are an established industry leader. Our team offers honesty, trust and the highest level of workmanship.

We are committed to ensuring that You’re in Control.

*Maintaining optimum indoor relative humidity can create a healthier environment in occupied spaces. Dry conditions make proper cleaning more difficult, increase the rate of transmission and take a toll on people’s immunity particularly on their respiratory systems (ASHRAE 2019, Condair 2020 & Iwasaki et.al. 2019). Relative humidity should be maintained at a range between 40-60%. Research suggests that this humidity range may have a positive impact on virus deactivation, human susceptibility to viruses and cross infection rates. Increased ventilation rates have been shown to reduce sickness. Adjustments in the rate of air exchange may improve health by reducing transmission of infection (ASHRAE 2017 & Conair 2020). It should also be noted that in most modern commercial buildings, operating HVAC systems form part of the essential safety measures and are required for occupancy. The scheduled routine maintenance of these systems along with fire protection and other essential services is a mandatory requirement.
