“What should I do when…?” This is the first question you ask yourself, the internet or your local technician about your AC while you’re nervously shuffling through the instruction manual. Don’t press the panic button (yet)! We put together 5 of the most common situations for you to know when your AC unit cries for help. Get your first-aid kit now!

  1. What should I do when the filter light is flashing?

If you happen to see a light annoyingly flashing on the AC unit, then it’s a clear sign that your filter requires cleaning. Keeping the filter free from debris is vital for both your AC and your family’s health. How often should you get it cleaned though? At home or the office, we recommend doing this routine once per month for optimal efficiency.

If the filter light keeps flashing even after cleaning, then your air conditioner needs to be reset. This can easily be a DIY operation, so all you have to do is remove the grille, find and press the reset button, in an HWS situation, while in ducted and commercial systems, action the reset button located on the controller.

It’s winter. Your AC unit is switched on “Heating mode” on a regular basis. All of a sudden, you start to feel a cold breeze coming from the AC vents. Have you messed up your Air Con settings? No, you haven’t! Technically, when the desired temperature is reached, the indoor unit stops heating the air and slows down the fan but it will keep circulating a small amount of air in order to measure the air temperature.

One of the reasons for this to happen is when you manually set the AC speed to “constant operation” and not letting the unit determine when to run the fan. This means the indoor fan will blow air regardless of the room temperature or mode of operation. To undo it, simply deactivate the option from the AC controller.

  1. What should I do when my AC indoor unit becomes very noisy?

what to do when AC unit is noisy?Probably one of the most irritating domestic noises is the one that comes out from the AC unit. A common cause is a blocked return air filter, which means that the air struggles to pass through, creating noise during operation. Another reason is the grille not fitting properly, allowing air to bypass it and “whistle” when the fan is running. In this case, we advise you to clean the filter first with a hose and then let it dry. Second, put the filter back into the grille and ensure it is centred to prevent the unwanted air gaps.

If the noise from your air conditioner becomes more intense, turn it off immediately! There is a possibility the fan motor mounts have failed and a qualified technician will need to assist you in this matter.

  1. What should I do when there is smoke, steam or water coming from the AC outdoor unit?

what to do when smoke coming from AC?Steam from your outdoor unit is pretty common during the winter season when your air conditioner is set on “heating” mode. This is actually due to condensation evaporating to the atmosphere and preventing airflow over the radiator coil.

If the steam smells like burnt plastic or rubber, switch off the air conditioning unit immediately and contact an experienced tradesperson to investigate the cause.

When you see water on the ground near your outdoor unit, it is because your AC is designed to remove moisture from the outdoor air on the heating cycle. To avoid this, get the unit drain to a downpipe or garden bed.

  1. If my AC broke, should I install a new unit by myself?

This is the ultimate question every experienced AC user tends to ask. However, when it comes to an air conditioning unit, only a licensed technician can safely and legally do the procedure.
