The same principles should be applied to an air conditioner that has started to make any concerning sounds–any new and worrying noises from your AC should prompt a call to a technician. But what sounds are we talking about?

If you start to pick up on any of these noises, make sure to reach out to us for an air conditioning repair in Tampa.


If it sounds like there is something inside your AC that is being shaken around, it is because there probably is. Loose bolts, screws, and even fan blades can create rattling noises while your system is in use. Make sure to have a technician address these before they get worse.


This noise is what can happen if a rattling noise is ignored for too long. Clanging is the sound of things loose in your system being bounced around. As you can imagine, a loose bolt or screw can do some serious damage to some of the more delicate components in your air conditioner so it is best to turn the system off and get a technician to address the problem quickly.


A screeching sound is usually going to be created by metal scraping against metal. This can be caused by a loose fan blade scraping around in its housing. It can also be created by a dry blower motor belt. In either case, you’ll want a technician to get a look at your AC to address the sound. It isn’t pleasant and it is only going to get worse the longer it goes on.

Hissing or Bubbling

Hissing or bubbling are both going to be caused by a refrigerant leak. Hissing is created by gaseous refrigerant leaking out of the line. Bubbling sounds are made when the leak is in the part of the line where the refrigerant is still in liquid form. The bubbling noise is due to air getting into the line. Refrigerant leaks are a problem that should be dealt with as quickly as possible.


You turn on your air conditioner and hear no noise. No whoosh of air, no clicking as the system turns on, nothing. Your air conditioner isn’t operating in an especially quiet manner. Your AC isn’t running at all! You have a problem that is preventing your system from turning on or functioning in any way.
