Five Signs Your Air Conditioner Needs A Service

We all know how hot and humid Australia can get, especially throughout the summer months. For many of us, air conditioning is the only reason that we are able to make it through in relative comfort. So, when our AC units start playing up, it can be decidedly uncomfortable when temperatures are reaching the mid-30s to low 40s. With air conditioners playing such an essential part in our everyday lives, it's important that you know the signs that yours may be due for a clean and service. Not too sure what to keep an eye out for? No worries! Take a look here at the top five signs your air conditioner needs a service.

1. It's blowing hot air instead of cold 

If you have recently noticed that your AC unit isn't as cold as it used to be, it's a sure sign that it's time for a service. If you have cranked the temp right down but it's still relatively warm, there's a good chance that there's an issue with the compressor or low refrigerant levels. 

2. Your electricity bill has spiked exponentially

If you have noticed a significant spike in your electricity bill but you haven't changed your electricity usage habits, there's a good chance that your AC could be to blame. When your unit isn't functioning at peak capacity, it generally needs to work harder to provide an adequate level of cool air, resulting in a huge increase in your electricity usage.

3. It's giving off bad odours when in use

An AC unit that is functioning properly should never give off any type of smell. If you can smell something coming from the inside of your AC when you turn it on, you definitely need to get it serviced. This smell could be coming from mould or mildew that might have built up on your unit or it could be from damaged insulation, both of which need to be sorted out ASAP. 

4. You've noticed a leak coming from the back of the unit

While a little bit of condensation or moisture coming from your unit is completely normal, bigger leaks that result in puddles or significant moisture around your system aren't. If your air conditioner is leaking, there could be a blockage in the drain tube or a refrigerant leak, both of which will need to be assessed and repaired by a professional.

5. It's regularly breaking down 

Perhaps the most obvious sign that your air conditioner needs a service is when it regularly breaks down or isn't functioning properly. This indicates that it may need parts replaced or a good internal clean. 


Having your air conditioning unit regularly serviced is a great way to keep it running at optimal capacity.
