Sydney Air Con Servicing

• Filter inspection/cleaning
• Evaporator inspection
• Condenser inspection
• Drainage check
• Temperature split testing
• Airflow testing
• Electrical inspection
• Controller check
• Zone inspection
• Refrigerant system inspection where required
• Outdoor unit inspection
• Operational test

The main difference is how much of the system is inspected, cleaned and tested. A split system is relatively self-contained, while ducted and commercial systems have more components, controls and airflow paths to check.

Split system servicing usually focuses on the indoor wall unit and the outdoor condenser. A typical service may include cleaning the return-air filters, checking and cleaning the indoor coil, inspecting the condensate drain and drain pan, checking the fan barrel and blower, inspecting electrical connections, testing the remote/controller, checking operating temperatures and airflow, and inspecting the outdoor coil, fan and compressor operation. The technician will also look for signs of refrigerant leaks, unusual noises, corrosion or electrical faults.

Ducted air conditioning servicing includes many of the same checks, but there is more equipment involved. In addition to servicing the indoor and outdoor units, the technician may inspect the return-air grille and filters, supply-air outlets, ductwork where accessible, zoning system, zone motors or dampers, wall controller, temperature sensors and overall airflow throughout the property. Drainage, electrical components, refrigerant operation and system pressures or temperatures may also be checked. A key part of ducted servicing is making sure air is being distributed correctly across the different rooms and zones.

Commercial air conditioning servicing is generally more comprehensive because commercial HVAC systems are often larger, operate for longer hours and may contain multiple units or specialised controls. Servicing can include filters, coils, fans, belts, bearings, motors, condensate drains, electrical components, contactors, capacitors, compressors, refrigerant operation, thermostats, sensors and control systems. Depending on the equipment, technicians may also inspect rooftop package units, cassette systems, VRV/VRF systems, air handling units, mechanical ventilation and building management controls. Commercial servicing will often place greater emphasis on preventative maintenance, identifying wear before it causes downtime, and recording equipment condition and faults for ongoing maintenance.

In simple terms: split system servicing focuses on one indoor and outdoor unit; ducted servicing also covers ducts, zones and whole-home airflow; commercial servicing typically involves more equipment, more detailed preventative checks and more complex controls.
