Benefits of regular HVAC service and maintenance

Extend equipment life

Like any other equipment, Heating, Ventilation and Air Conditioning systems require regular maintenance to keep it running properly. Servicing HVAC products on a frequent basis is an investment in consistent performance and longevity of the equipment. The Mitsubishi Electric Service and Maintenance team deliver an end-to-end service that can help you to:

  • Optimise efficiency 
  • Reduce carbon emissions
  • Optimise air quality
  • Extend equipment life
  • Avoid larger repairs

Optimised efficiency

Regular servicing allows the HVAC unit to run at peak performance. When one part of the system isn’t running effectively, there can be inefficiencies across the board, meaning the unit will have to work harder to heat or cool a room. This can lead to higher energy costs being spent to run the unit, as well as more energy required to run it.

Reduced carbon emissions

The urgent need to reduce carbon emissions, and the ongoing drive to meet the UK’s net zero plans, are demanding smarter energy efficiency and control in cooling, heating, ventilation and the associated technologies.

Regular maintenance of these systems is key to achieving overall energy efficiency and as building owners face tighter regulation on energy use, it’s important to view service and maintenance as a key part of your energy efficiency strategy.

We work alongside the Institute of Workplaces and Facilities Management to ensure that Facilities and Building Managers receive the support and information they need to maintain and replace their HVAC systems to comply with regulations whilst achieving optimum efficiency.

Improved Indoor Air Quality

Indoor air pollution can be a major problem which can be minimised with routine HVAC maintenance. Part of regular HVAC servicing is ensuring the inside of the system is as clean as possible and changing the air filters. Over time, it is normal for there to be rust and dust buildup, and cleaning wall vents and HVAC ducts can help to improve the air quality of any commercial space, which is key for the general health of your employees by supplying them with clean, filtered air.

Following the updated Part F and L of the building regulations, the focus on providing a healthy indoor environment, that is also optimised for efficient performance is even more important – this means keeping up with maintenance of air conditioning and ventilation systems. We can review what is in the building today and help to plan a maintenance programme that will improve Indoor Air Quality and energy efficiency – without the immediate need to replace an entire system.

Extended equipment life

Commercial HVAC and chiller systems can sometimes be one of the most expensive parts of a building, but frequent servicing and maintenance can extend the life of the equipment. Regular check-ups can help avoid premature replacements and provide a longer lifespan.

Avoid larger repairs

HVAC systems are composed of several smaller components, for that reason, issues can naturally arise over time. Regular planned, preventative maintenance ensures smooth running of all equipment and reduces the risk of emergency breakdowns and expensive HVAC repairs. It is more manageable to catch potential issues early and address them at that point, rather than allowing them to develop into big problems that require more time and effort.
