Does your air conditioner make a loud noise when starting? Upon getting home from a hard day’s work, you turn on your air conditioner only to hear it making strange noises. Eventually, the noise may go away but this has been happening consistently every time you turn on your HVAC system.

If your HVAC system makes a noise when you turn it on this can be a sign of damage. Air conditioners may present with noises either just when turning the unit on or throughout it being in use.

In this article, we are going to talk about noises that may occur immediately after you turn your HVAC unit on. Each sound may indicate a different problem, so it is important to identify the type of sound that your unit is making.

Air Conditioner Loud Noise – Reason-> Clicking Sounds

Clicking sounds coming from your AC unit every time it is on can mean that you are more than likely dealing with electrical problems. Usually in this case, when you turn the unit on it will make a clicking sound but will not turn on at all.

If your HVAC unit is making a clicking sound, then it is time to call in an HVAC specialist

Air Conditioner Loud Noise – Reason-> Banging Noises

If your HVAC system has a loud banging or pounding sound when you turn it on, it may mean there is debris in the unit. Simply remove the debris from inside the unit. It can also be a loose fan that is banging up against the HVAC cage.

Noisy Screeching

A screeching noise can indicate that the bearings of your fan motor may be failing. If this happens then there is no other choice but to call in an HVAC specialist. If you continue to run your HVAC system this will cause irreversible damage to the fan motor bearings.

What Else Can Be Done to Stop A Noisy AC When It Turns On?

Check the Lubrication on the Motor

If your HVAC system is making a screeching noise when you turn it on, it could mean that the motor needs more lubrication.

Tighten Any Loose Parts

Very often the vibrations cause an HVAC system can cause some of the screws to come loose. This will cause a rattling sound. There is a fix to this problem. Maintain a regular schedule to your AC unit.

Maintain Coil Fins and Fan Blades

It is important to straighten the coil fins of your unit using a fin comb and a vacuum cleaner to collect any dirt or debris. By doing this you can improve the overall efficiency of your HVAC system.

The fan blades on your air-conditioning unit are just as important and need cleaning to remove any debris. Dirty fan blades can be the cause of banging noises coming from your unit.
