AC System Noises & What They Mean


No– it’s not your neighbor banging on your door or a murderer trying to break in. It’s just your compressor! Your compressor is the outdoor portion of your AC system, and it’s much more likely to get damaged due to the fact that it’s constantly outside and unprotected. If your compressor is making a banging sound, you’re likely dealing with a loose or broken part. This is typically a minor issue, and it can be repaired by your local Tampa AC company pretty easily. Here at Air Express, we can fix these issues through our same-day service calls! However, if your entire AC system is over 10 years old, you might be dealing with a larger broken component. In that case, you might need to replace your entire compressor. We always recommend total system replacement as opposed to partial replacement, especially considering energy efficiency savings and flexible financing options!


Yikes! This is the scariest noise of all. It’s also the most hazardous, so do not ignore it if your AC system is screaming at you! You could be dealing with a refrigerant leak or abnormally high pressures, both of which could harm you, your home, and your family.

Luckily, this is not a common sound, but if you ever experience it, turn your AC system off immediately and call your Tampa AC company for emergency service! Scary sounds are (typically) scary for a reason, so listen to your gut and leave the heavy lifting to the professionals.


This sound is a little harder to pick up on, but if your Tampa air conditioner is located near your bedroom, it might be loud enough to keep you up at night. And the one thing we all need more of is sleep! Humming is best diagnosed by your Tampa AC company, because it can be caused by so many things: a loose part, electrical problems, an issue with your fan motor, and more. It’s not super concerning or urgent, but it should be dealt with sooner rather than later to prevent further damage to your AC system!


A clicking sound is most frequently related to your air conditioner cycling on and off. Inverter AC systems, the newest and most efficient system within the world of HVAC, do not EVER make this sound because they don’t cycle at all! Learn more about inverters here.

However, if you have an older system on your hands, your system might click on and off to deal with the ever-changing heat load in your home. If you’ve noticed this sound increase in frequency, you might be dealing with electrical issues or a disconnect involving your thermostat. When clicking sounds become more noticeable than normal, call your Tampa AC company for a diagnostic!


This is kind of a gross sound, but don’t worry– you don’t have a swamp monster in your backyard! A bubbling or gurgling sound is likely due to a clogged drain line or a refrigerant leak. In the event that it is a refrigerant leak, your system should be attended to ASAP to prevent further damage. If it’s your drain line, you are able to shop vac your line on your own pretty easily. Frequent issues with your drain line can be prevented through regular maintenance, so we always recommend signing up for our annual maintenance membership!
