Air conditioning systems don’t run in complete silence, although advancing technology has made them quieter than ever. When the AC in your house is running, you’ll hear the whir of the fan motor and the hum of the compressor motor, the whoosh of air moving through the ductwork, occasional dripping from condensate moisture being removed from the system, and that’s about it.
If you do hear something different, or the AC is louder than normal, it’s sending you a sign that something is wrong. It may be a simple problem, or it may require you can call for expert HVAC service in Warner Robins, GA to diagnose the AC and see what needs to be fixed. Here is our guide to the common AC warning sounds to look out for.
1. Banging or Clanking
If you hear a banging or clanking noise, it usually means that there is a loose or broken part inside the compressor. This could be a connecting rod, piston pin, or other components. This sound is a sign that your air conditioner needs immediate attention from a professional technician.
2. Buzzing
A buzzing sound coming from your air conditioner can be caused by several issues such as loose parts, debris in the unit, or electrical problems. It could also indicate that the motor is going bad or that the unit is beginning to freeze up. Whatever the cause, it’s important to have a technician inspect the system to prevent further damage.
3. Hissing
Hissing sounds are often associated with refrigerant leaks. A refrigerant leak not only affects the performance of your air conditioner but can also be harmful to the environment and your health. If you hear hissing, it’s essential to have the system checked by an HVAC professional to locate and repair the leak.
4. Squealing or Screeching
High-pitched squealing or screeching sounds typically indicate a problem with the fan motor or blower motor. It could be due to a worn-out belt, or the motor bearings might be failing. This noise should not be ignored, as a failing motor can lead to a complete system shutdown.
5. Clicking
While it’s normal to hear clicking when your AC system starts up or shuts down, continuous clicking is not. It could be a sign of a malfunctioning thermostat or an issue with the electrical components of the system. Continuous clicking should be inspected by a technician to prevent potential electrical failures.
6. Rattling
Rattling noises often suggest that something is loose within the air conditioner, such as screws, bolts, or debris that have gotten into the unit. If the rattling isn’t addressed, it could lead to more serious damage as the loose parts continue to move around.
If you’re hearing any of these warning sounds from your air conditioning system, don’t wait for the problem to get worse. Our experienced technicians can quickly diagnose the issue and provide the necessary repairs to get your AC running smoothly again.
