The HVAC statistics to shock FMs

The cooling coil within the air handling unit (AHU) of a building’s HVAC system is essential for helping supply occupied spaces with clean, safe air.

If the cooling coil is not properly maintained, a combination of mould, bacteria, viruses and other contaminants – known collectively as biofilm – may grow on it.

As well as exposing occupants in schools, hospitals, offices and other shard spaces to potentially harmful air, this impedes the coil’s efficiency, meaning the system must work harder to achieve the same level of performance. This in turn increases maintenance and reduces the equipment’s lifespan.

Here are some startling statistics on indoor air quality in buildings served by an HVAC system:

  • HVAC systems account for up to 60% of a building’s total energy cost
  • Dirty HVAC coils use as much as 25% extra energy due to inefficiency
  • 75% of IAQ problems are related to HVAC
  • 60% of indoor spaces expose occupants to air pollution

Gibbons Ultraviolet Solutions supplies and installs non- invasive chemical free 24/7 disinfection systems that can be mounted within an AHU to continually expose the cooling coil to high-output ultraviolet-C (UVC) light.

This eliminates biofilm and prevents its re-growth, ensuring that building occupants breathe clean air while HVAC equipment runs efficiently and reliably.

The low-maintenance systems from Gibbons Ultraviolet Solutions, such as CoilCare®, can be designed to fit all AHUs containing cooling coils and take just a few hours to install, with our engineers visiting site at a time that suits you and your business.
