As the temperatures begin to rise, keeping the AC unit in your Miami, Florida, home running properly is critical to staying comfortable. That means staying on top of possible problems that can turn into larger issues. Below are four AC sounds that you should never just ignore.


Rattling noises are never good and are typically a sign that a part has come loose somewhere in the system. If the noise sounds like it is coming from the outdoor unit, it could be something caught inside that is hitting the condenser fan. It could also be a loose bolt on the housing unit or condenser fan coming loose. Rattling noises that are detectable at the indoor air handler could also be loose screws or an unstable supply air fan.


If you detect bubbling or gurgling coming from your system, it could be a sign that your refrigerant levels are low. If this is the case, the noise will most often come from the piping and the walls. This issue may not be a safety emergency, but failing to repair it can result in poor performance and higher than normal utility bills.


When your system has loose fan belts or worn bearings, you may hear some squeaks or high-pitched squealing. These are typically minor issues that can be quickly fixed by a service technician. The squeaking noise that should cause major concern is a loud squeak or screech coming from the unit’s condensing section. This is often a sign that the compressor is about to give out.


Clicking noises can be considered normal when the system turns on or off. What is not normal is hearing rapid, repeated clicking that doesn’t seem to stop. This is often a sign of an electrical problem. It could be bad capacitors, switches or contractors.

If you notice any of the sounds listed above coming for your AC unit, it is time to bring in the professionals. Contact RCI Air Conditioning Company at 305-307-5348 today.
