​Refrigeration & Air Conditioning - Maintenance & Repairs

​​Maintaining Your Air Conditioning Systems

Avoiding air conditioning breakdowns is a significant priority for all of our clients. Our years of experience in the industry has proven 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 there is a problem, significantly increases the whole-life costs due to premature component failure and inefficient energy use. In short, avoiding Air Conditioning maintenance costs more in the long run.

Our Planned Maintenance agreements are specifically tailored to suit your particular environment and installation, and the frequency of our maintenance visits will be agreed with you to ensure the optimum reliability and efficiency of your system.

Our maintenance visits always include the following activities:

• Check and clean the outdoor unit and indoor unit coils and fins
• Check fan, fan motor, compressor and compressor mountings
• Check all electrical connections
• Check operation of heater and any interlocks
• Check fuses and test operation of electrical isolator and protection devices
• Check condensate pump and float/sensor
• Check and flush condensate drain and tray, descale and add water treatment as necessary
• Check condensate drain pipe work for water tightness
• Check air ducts, air grilles, filters and insulation
• Check refrigerant pipe work for integrity and thermal insulation
• Monitor refrigerant suction and liquid line temperature and pressure
• Check expansion valves
• Check start and running current
• Check Delta T across coil in cooling and heating modes
• Check unit operation, controls and settings
• Ensure unit is clean and free of damage
