Air conditioner loud noise when starting8 min read

Reading Time: 6 minutes

Air conditioners can be very loud when starting up, and this can be startling and annoying for many people. In most cases, the noise is simply the sound of the compressor starting up, and it will usually only last for a few seconds. However, there are some things that you can do to help reduce this noise.

The first step is to make sure that your air conditioner is properly sized for your home. If it is too large, it will have to work harder to cool your home, and this will cause it to be louder when starting up. You can also try to reduce the amount of noise that the air conditioner makes by using a sound-deadening insulation material around it.

If the noise is still bothering you, then you may want to consider buying a model that has a start-up delay feature. This feature will delay the start-up of the compressor for a few seconds, which will allow you to get settled in before it starts running.

Finally, if all else fails, you can always try to contact the manufacturer and ask for a refund or exchange.

Why does my air conditioner make a banging sound when it turns off?

There are a few reasons why your air conditioner might make a banging sound when it turns off. One possibility is that the refrigerant is escaping from the system. This can happen if the AC is not properly sealed or if there is a leak in the system. When the refrigerant escapes, it can create a loud bang as it suddenly expands.

Another possible cause of the banging noise is a problem with the fan motor. If the fan motor is not working properly, it can cause the compressor to overheat. This can lead to a loud banging noise when the compressor turns off.

Another issue that can cause the AC to make a banging noise is a problem with the start relay. If the start relay is not working properly, it can cause the compressor to start up and shut down repeatedly. This can create a loud banging noise.

If your AC is making a banging noise, it is important to have it serviced by a professional. There could be a problem with the system that needs to be fixed.
