Maintenance & servicing
Keep your system running at its best
Regular servicing extends the life of your air conditioner, lowers running costs, and catches small problems before they become expensive ones. Book a service with Centigrade today.
Why regular servicing matters
Air conditioning systems work hard — especially through Sydney's long, humid summers. Over time, filters clog, coils accumulate grime, and refrigerant levels can drift. A system that isn't serviced regularly has to work harder to reach your set temperature, which drives up your power bill and puts unnecessary strain on the components.
An annual service by a licensed technician restores peak efficiency, improves air quality, and gives you confidence that your system won't let you down on the hottest day of the year. We service all major brands and system types — ducted, split, cassette, and bulkhead.

What's included in a service
Filter clean & inspection
We remove, clean, and inspect all filters — blocked filters are one of the most common causes of reduced performance and poor air quality.
Coil cleaning
Evaporator and condenser coils are cleaned to restore heat exchange efficiency and prevent mould and bacteria build-up.
Refrigerant check
We check refrigerant pressure and inspect for leaks — low refrigerant is a leading cause of poor cooling and compressor damage.
Electrical inspection
All electrical connections, capacitors, and contactors are inspected and tightened to prevent faults and ensure safe operation.
Performance testing
We measure supply and return air temperatures to confirm the system is delivering the correct temperature differential.
Service report
You receive a written report of everything checked, any issues found, and our recommendations — no surprises.
Repairs & fault diagnosis
If your system isn't cooling properly, making unusual noises, tripping the circuit breaker, or displaying an error code, our technicians can diagnose and repair the fault quickly. We carry common parts on the van to minimise downtime.
We work on all major brands including Daikin, Mitsubishi Electric, Fujitsu, Samsung, LG, Panasonic, and more. If a repair isn't cost-effective, we'll give you an honest assessment and a quote for a replacement system.
