Why is my AC making a clicking noise?
Clicking can be an ambiguous sound to hear from your air conditioning unit. It could imply that a part is loose and is hitting another part within the system or it could mean that the fan is brushing up against something as it’s in motion.
A clicking sound can be particularly concerning because it could also signal a serious issue with your air conditioner’s electrical connection. If your air conditioner clicks once when it turns on, that’s considered normal. However, repeated clicking is indicative of a problem.
And if there is an issue with the control panel, faulty electrical signals produce clicking noises with minuscule sparks of electricity, as they continually cause switches to turn on and off. If the clicking accompanies sparking, power the system down and call the Experts to examine your system as soon as possible.
