7 Signs Your Aircon Unit Is Failing

A failing aircon unit is the last thing you want to have on hot summer days or even on a regular basis. But how can you tell if your aircon unit is on its way out or just acting up? Here are the signs that your aircon unit is failing: 

1) The air coming out of vents is warmer than usual.

Your aircon unit’s compressor is failing to make ice. Most of the time your aircon unit will give you plenty of warning signs before it comes to an end. However, it could also suggest that it might be time for a replacement.

2) The aircon unit makes strange clicking or buzzing noises, especially when you first turn it on. 



This often means that the air in the outside vents is too hot and dry – in order for your aircon unit to function properly it needs moisture. 

3) Air comes out of vents when the heating is on.

When this happens, or when you notice the compressor is making a loud noise, then it is trying to get rid of built-up heat, moisture, and pressure.

4) The fan is blowing but there’s no cool air coming through

You should make sure that your aircon unit turns off if it detects low levels of airflow, otherwise, the internal components will overheat and eventually fail. Alternatively, if it doesn’t detect low levels of airflow then the problem could be with one of the other components inside your aircon unit.

5) The compressor is leaking fluid.

If your aircon unit is leaking oil or fluid, this is a sure sign that it’s on its way out. A lot of people think they can prolong the aircon issue by draining or replacing the fluid inside their aircon unit when this usually causes more serious aircon issues and costs a whole load more money.

6) The aircon unit cools for about five minutes after turning on.

This means that the air in your aircon unit isn’t circulating properly and the compressor has to work extremely hard to generate cold air. This certain aircon issue is caused by a low level of airflow, which may be caused by a blocked filter, dirty vents, or a burnt-out fan. 

7) The aircon unit just doesn’t want to turn on at all.

This major aircon issue could also stem from a minor aircon issue with the internal fuses or PCB, in any case, it is recommended to contact a professional aircon servicing company so we can get our team over to take a look.
