AC will buzz loudly after running for several hours
Occasionally our AC unit will start making a loud buzzing sounds after running for several hours. The fan looks to be spinning normally (it looks slow in the video but that’s just the camera, it’s much faster when observed) Usually if I turn it off for a bit and then back on, it will run quietly again.
This used to be infrequent but is happening more and more. What could the potential reasons be?
