Noises Your Air Conditioner Made and What Do They Mean

Air conditioners, by nature, are noisy. Whatever type or brand of air conditioner you have, it will tend to produce noise to some extent. The latest airconditioning in Perth is quieter than its predecessor but it still produces noise, although at a lower level. High-efficiency air conditioning units included sound- reducing technology and two-stage compressors to keep noise produced by AC unit below 55 decibels. So, if you hear loud and unusual coming from your AC unit it could be a sign of a major problem. Paying no attention to weird and unusual noises produced by your AC unit can lead to major expense or even a replacement of the entire unit.

The sooner you can identify noise and its cause the sooner you can resolve the issue. Here are the eight common sounds your air conditioning system may produce and what they may signify.

1.    Banging

If you could hear a banging noise from coming from your air conditioner, it might be a sign of a broken or loose part. It could be a crankshaft, piston pin or a connecting rod that got loose or broken inside the compressor. It could mean that you have unbalanced indoor blower. It is advisable to call an airconditioning repairs in Perth for check-up and repair.

2.    Clanking

The loud clanking sound is also a sign that there might be a loose or unbalanced part inside your AC unit. It is likely that compressor itself become loose, or the outdoor fan or indoor blower blades are hitting other parts. If you are hearing clanking sound coming out of your AC unit, you should take an action immediately or it could get worse and create bigger problems.

3.    Clicking

The clicking sound you hear at the startup and shutdown of the AC is normal. However, the constant clicking is not. The constant clicking could a sign of a failing thermostat or a defective part. Since your AC system is made up of many electrical and mechanical parts there might be something wrong with one of them that cause your AC unit to produce clicking sound.

4.    Buzzing

There are several reasons why your air conditioning system produces buzzing sound. The buzzing sound may cause by one or more of the following:

-    loose parts

-    unbalanced or loose fan blades

-    stuck debris in outdoor or indoor unit

-    condenser coil needs cleaning

-    air filters needs cleaning

-    defective outdoor fan motor

-    cooper lines are rubbing against something

-    unbalanced or defective blower

-    refrigerant leak

5.    Squeaking

The squeaking or squealing sound coming out from your AC unit signals defective indoor blower or outdoor fan motors.

6. Rattling

The rattling sound produced by AC unit usually means that your AC system is deteriorating and some parts are starting to lose, maybe due to old age or lack of maintenance. Another reason that causes the rattling sound is the debris and dirt that clogs the system. The first thing you could do when you hear your AC unit rattling is to check if there are loose screws or bolts, change your indoor air filters and clean the condenser coils.

7. Screaming

Yes, your AC unit may produce screaming sound in the form of high pitched whistling.  If you hear a screaming or high pitched whistling coming out of your AC unit, you should shut down your air conditioner immediately and call the air conditioning repairs in Perth. The screaming sound is usually due to a refrigerant leak. A refrigerant leak is not only damaging to the AC unit, it is also harmful to your health. If your AC unit turns off automatically, consider this as a good sign. It is the sensor doing its job to protect you from a dangerous situation.

If you hear an unusual sound coming out 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.
