Air conditioners are great because they keep you cool in the summer and warm in the winter. They’re a staple in most Australian homes, and without them we would struggle to function through those hot summer months.

But like with anything, there’s the possibility that you’re going to run into problems with your air conditioner. Check out our quick guide to help you troubleshoot what the problem may be.

Start by turning off your air conditioner

Make sure that your air conditioner is completely turned off and all power that is linked to the air conditioner has been turned off as well.

Check the air filter

Your air conditioner will require the air filter to be changed regularly in order to keep the air conditioner running efficiently. If you don’t change it, you might find that the filter becomes clogged and the air conditioner runs inefficiently. Make sure therefore that you replace the air filter with the right size, thickness and kind for your air conditioner. You might find that your air filter is torn, ill fitting or missing altogether, which can lead the evaporator to become clogged with dust and fungi.

Check the refrigerant

Every air conditioner should have a certain level of refrigerant inside at all times; this is what cools down the air that is pumped through the system. If your refrigerant gets too low, you may find that your air isn’t cooling down as much as it should. Check to see how much refrigerant you have and see if it needs topping up.

Check the condenser and evaporator

Check the condenser and evaporator to see if you can see any issues. You may find that both live together in the window unit, depending on the type of air conditioner you have. They both have fans, electrical relays and connections, so you may find an issue that could be affecting the performance of your air conditioner system.

Check the thermostat

If your air conditioner is running with a broken thermostat, it makes controlling the temperature impossible, which could result in your air conditioner stopping entirely, working continually, or starting and stopping; regardless of how your system reacts, it will be inefficient and result in expensive electricity bills. Therefore, make sure to check your thermostat to see if it’s intact.
