HVAC maintenance & service contracts

Our HVAC service contracts and air handling unit maintenance agreements provide a planned, preventative AHU maintenance solution to sustain the optimum efficiency of your air handling unit or BEMS, enabling you to see real savings in energy costs and reduced carbon emissions. Another key component of our services is ensuring you are aware and compliant with any legislative requirements, e.g. F-Gas Regulations.

Planned AHU maintenance and HVAC service contracts not only assist in preventing unit and system breakdowns, but also helps to improve system resilience, increase energy efficiency and enhance system optimisation for improved performance and increased profitability.

We offer a full range of HVAC service contracts and maintenance plans for AHUs, cooling equipment and BEMS. These contracts offer varying levels of support and cater for both our own and all third party manufacturers’ equipment.
