Top 5 Reasons Why Your Window Type Air Conditioner Is Making Unusual Noise

It is normal for an air conditioner to make some noise. Noise means the motor of your AC unit is working. However, there are noises that come from AC which are not normal. The unusual noise such as buzzing banging, clanking, squealing, clicking, and rattling is telling you that there is something wrong with our AC unit. If you hear an unusual sound coming out of your air conditioning unit, do not ignore it because a simple buzzing sound may turn into a more serious problem that can cost a lot of money and potential hazard to your health.

One of the drawbacks of the window type air conditioner is that they can be noisy. Read on to help you identify what are the possible causes of the unusual noise.

1.    Foreign objects

If your air conditioner suddenly starts making loud noises, it is possible that a foreign object gets inside the system. This problem is quite usual in a window-type AC because its outer part hangs outside your home which makes it exposed to flying debris and small animals and insects.

If this problem happens, just turn off your AC unit, unplug it and open the front grill. Use a flashlight and look inside the unit. Remove the foreign object that gets inside the system and secures the front grill back in place. Plug and start your AC once more.

2.    Bent fan blades

In some cases, the presence of a foreign object inside the AC system can cause other problem such as bent fan blades. Hard impact on the AC can also cause a similar problem. Bent fan blades usually produce clanking or clicking noise. You can solve this problem by straightening the blades using pliers or by your hands. However, if you are not 100% sure whether the fan blades are bent or not, it would be wise to consult an air conditioning service Perth.

3.    Vibration on the window frame

Window-type air conditioners are usually mounted on the window frames. If not installed properly, it can cause a lot of vibration which can produce loud noises. To determine whether the noise due to the vibration on the window frame, touch the sides of the window frame and if they vibrate excessively you should call the air conditioner installation in Perth to install your AC properly to minimize the vibration.

4.    Loose front grill

If the front grill of your AC is not fastened properly, it may vibrate and would produce unusual noise. To resolve this issue, just simply remove the grill and mount properly on the AC. If the locking mechanism of the front grill has been damaged, you may need to replace it.

5.    Insufficient lubrication

If your air conditioner is not properly lubricated, it can produce loud persistent noise. For instance, a fan motor that is not properly lubricated can result in annoying continual noise, and it could damage the motor too. If this happens, turn off the AC and call an experienced air conditioning service provider in Perth to lubricate the fan motor. If you are not an experienced AC technician, do not attempt to open the sealed fan motor. You may cause more damage if you don’t know how to deal with it properly.
