10 Most Common Air Conditioning Problems

In the hot Australian summers, air con is essential to everyday life, so problems with your unit can be a huge disruption. Read on to discover some of the most common air conditioning problems so that you're better equipped if anything goes wrong in your home. 

1. The AC won't turn on

Your AC not turning on could be due to faulty wiring or electronics or a problem with the thermostat.

In the warm weather, it's common for the AC to be on fairly regularly. However, it shouldn't be on all the time, turning off when the temperature in your home reaches a certain level. If you notice it stays on constantly despite your home reaching a comfortable temperature, there is a problem.

The cause of your AC only emitting hot air could be a filter that is dirty or something blocking the ducts. Make sure to clean the ducts regularly and replace the filters every few months to avoid this.

An inability to produce cool air could be a result of insufficient coolant levels. More commonly, though, it is simply a tripped circuit breaker.

This could be water or refrigerant. It can be hard to tell if you have a refrigerant leak, but look out for bright liquids near the air conditioning unit. Excessive condensation can also be a sign of a leak.

The correct term for this is short cycling and it occurs when instead of following through an entire cycle of cooling, the system repeatedly turns itself on. Again, this could be a problem with the thermostat or simply with the air filters being too dirty.

Despite the intention of the system being to cool down your home, the formation of ice is a sign of a problem. It is essential that you get a professional to look at your system as fixing the root issue could save you a lot of money.

If you are facing this problem, it could be due to faulty installation and may suggest a fault with the wiring.

Burning smells can signal a larger problem. Burning or musty odours coming from vents or close to the AC unit are the most common.

Any kind of out-of-the-ordinary noises like vibrations, grinding or high pitch sounds are a sign of a problem, so don't ignore them, especially if they start suddenly.
