"The risk of air conditioning spreading Coronavirus is extremely low. Good ventilation is encouraged to help reduce the risk of spreading Coronavirus." (Source, The HSE)

As businesses, schools, and public places are beginning to re-open and increase occupancy - we wanted to provide some clear guidance from official sources to ensure that you have the most up-to-date guidance on how to provide your staff with the safest environment possible. 

There has been much conflicting information circulating, regarding the use of air conditioning and air handling equipment; please find below key points which have been recently advised by the Health & Safety Executive (HSE) for your assurance and review. 

Air Handling

If you have a centralised ventilation system which removes and circulates air to different rooms, we recommend the following: 

  • Ensure servicing is up to date
  • Ensure correct grade filters are installed and in good condition 
  • Close down re-circulation vents, operate on full fresh air
  • Test fresh air input, increase volume where required
  • Eliminate open components where possible (isolate Thermal Wheels) 
  • Increase operation times before and after occupancy 
  • Check condition of seals and replace if necessary 

Air Conditioning 

You do not need to adjust any other types of air conditioning systems, and we recommend the following: 

  • Continue to operate systems as normal 
  • Ensure servicing and filter cleans are up to date 
  • If units have been idle for a prolonged period, ensure equipment is cleaned and tested before turning it back on. This is to ensure elimination of potential Coronavirus spread, but also, to ensure no risk of Legionella from condensate water having been resting in drip trays/drains

As always, IRS are on-hand to assist and provide expert guidance and servicing where required, so please do not hesitate to contact our service team on 01527 577999, or email your enquiry to ian@irs.co.uk, or scottdavis@irs.co.uk
