You can start by keeping the external unit clean, by simply wiping it down every few weeks and making sure no leaves get caught up near it. You also need to clean the return air filters (internal unit), especially if the unit is exposed to a lot of dust. This can cause your unit to ice up if left to accumulate. The same applies to the external condenser fins, which needs to be regularly cleaned. If you are not sure about how to maintain your air conditioner, it is always recommended that you contact a qualified air conditioning repairer in Canberra to assist you.
When it is humid outside, check the condensate drain to make sure it is not clogged and is draining properly.
Air conditioner failure
If your air conditioner fails, begin by checking any fuses or circuit breakers. Let the unit cool down for about five minutes before resetting any breakers. If a central air conditioner’s compressor stops on a hot day, the high-pressure limit switch may have tripped; reset it by pushing the button, located in the compressor’s access panel.
Air conditioner coils
In time the evaporator coil will collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. Check your evaporator coil every year and clean as necessary. You should minimise dirt and debris near the condenser unit. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. Cleaning the area around the coil, removing any debris, and trimming foliage back at least 2 feet (0.6 meters) allow for adequate airflow around the condenser.
