HVAC maintenance and indoor air quality

HVAC maintenance and indoor air quality

Heating, air conditioning and ventilation systems control the air temperature and air flow within buildings, but without regular maintenance, these systems may not perform efficiently enough to deliver sufficient quality of air.

Spring allergens are on their way in, but that’s not the only reason to look at improvements to indoor air quality (IAQ). Poor air quality can exacerbate common conditions like asthma, can cause dry, itchy eyes, and can even result in the health condition ‘Sick Building Syndrome.’ This syndrome can result in everything from sore throats to lethargy.

What can be done to improve IAQ?

Artificial environments, like office buildings, shops, and hospitals, typically require complex HVAC systems. These systems must be designed and installed intelligently to ensure air flow is maximised.

The design of the HVAC system should involve a holistic approach, considering the type of environment and equipment being used within, as well as the occupancy, architecture and outdoor air quality. Bespoke HVAC systems that are designed well for the space can deliver good indoor air quality, prevent mould, and control humidity. 

These systems also require regular monitoring and maintenance. This helps ensure they’re working efficiently, are clean, and are still sufficiently serving the needs of the building and its occupants.

Regular HVAC maintenance will not only improve health and safety for building occupants, it can also contribute to improved efficiency, while reducing risk of breakdown and saving on costs.

Beyond scheduling regular inspection and maintenance, there are a few things facilities managers should keep in mind to provide good indoor air quality.

 10 ways to improve air quality

  • – Monitor and report any leaks, malfunctioning equipment, or strange noises
  • – Ensure that supply vents are not covered or blocked by furniture
  • – Discuss any changes of use with an HVAC engineer, i.e. if staff levels have increased or new equipment has been put into use within the facility
  • – Changing thermostats to ‘on’ instead of ‘auto’ can help to ensure that fresh air is constantly circulating, as it will occasionally switch off when set to ‘auto’
  • – Request an inspection and possible replacement of air filters
  • – Where applicable, have humidifiers checked for mechanical stability and cleanliness quarterly
  • – Dispose of waste regularly, including emptying bins daily, which can prevent build-up of odours
  • – Make sure that your HVAC engineer inspects and maintains air handling units and ductwork
