Maintenance & Servicing

Avoiding air conditioning breakdowns is a major priority for all our customers. Our experience also tells us that regular planned maintenance is essential to ensure efficient, trouble-free running of any air conditioning system.

Cutting back on maintenance has been proven to be a false economy. A reactive approach to maintenance, such as repairing the system only when breakdowns occur, significantly increases through-life costs due to premature component failure and inefficient energy use.
