Air Conditioners: Troubleshooting Tips

Air conditioners, or air conditioning units, are ideal for keeping cool through the warmer months. The inbuilt refrigeration system helps to control and regulate the air temperature making your home environment comfortable.  

If not performing as you’d expect it to, this can become frustrating with temperatures rising both internally and environmentally. In this guide, we have highlighted common queries and solutions for your air conditioner. 

The unit does not turn on, but it has power.

If you find the appliance is not turning on, but it has power, there are some things you can check to get it working again.  

Firstly, you should check the drainage tray if your unit has one. This is to ensure that there is not an excess build-up of water. If the appliance detects excessive water it may not fully turn on until it is removed.  

You can also try using an alternative mains plug socket in case there is an issue with the socket itself. If this fails, you can try a power reset on the appliance. This is done by disconnecting the unit from the power, holding down the On/Off button for 15 seconds, and then plugging back in. 

The air is not cool enough.

When using your air conditioner, you expect the air to feel cool to know you are getting the best results. If the air does not seem cool enough, we recommend closing any nearby windows and doors, and securely attaching the exhaust duct. This helps to keep a steady flow of air and prevents warm air from entering the room and increasing the temperature. We also recommend decreasing the set temperature using the control buttons to the desired preference.  

As part of the maintenance of the appliance, you should clean the air filter from any obstructions which may be restricting the airflow. You can also check our post on tips to improve the efficacy of your air conditioner by clicking here.

The unit is noisy or vibrating.

Does the unit appear to be vibrating? Whilst vibrations can be normal, if it seems excessive you can try to resolve this with some simple checks.  

Firstly, clear the air filter of any debris that may be vibrating during the cooling process and creating noise.  

You can also check that the unit is on a flat, level surface. If on an uneven surface, it may vibrate during the conditioning process and seem louder due to the vibrations against the levelling off the ground. 

There is a gurgling sound.

If you notice a gurgling sound when your air conditioner is in operation, this is not something to be concerned about. This is normal for the operation of the appliance and is produced by the flowing refrigerant inside the conditioner, very similar to refrigerators. If the noise still appears to be excessive, we recommend contacting the relevant support team for further assistance.
