Unusual Noises

AC systems typically produce a low hum when running, but if you hear strange noises such as grinding, squealing, or banging, it may indicate a mechanical problem. Loose or broken components, such as a failing motor or a misaligned belt, can cause these sounds. Addressing these issues early can prevent costly repairs or replacements.
