When the warmer months arrive in Canton, MS, you depend on your air conditioner to stay cool. It’s easy to become alarmed when your AC system starts making strange noises. Here are three common AC noises and what causes them:
Banging AC Noises
If you hear banging noises from your AC system, it’s likely a sign of trouble. Sometimes, it may result from something as simple as a loose component.
One common source of banging noises is a loose blower fan. If the fan comes loose from its mounts, it may start banging against the system’s case. If the blower’s fan blades loosen, they may bang against the fan’s housing when spinning.
However, if the banging noise comes from your AC system’s outdoor unit, it may be a compressor issue. Those kinds of noises often indicate an internally damaged compressor. In that case, you may need an AC replacement right away.
Buzzing Sounds
If you hear buzzing noises from your AC system, it often indicates an electrical issue. One common cause of buzzing sounds is a failed capacitor. Another potential reason is a faulty contactor switch.
Hissing Sounds
Hissing noises typically indicate a refrigerant leak somewhere in the system. You should turn off your air conditioner and contact a professional immediately when you hear such sounds.
Depending on the quality of your AC installation, it may experience refrigerant leaks around its fittings. Fortunately, those are relatively easy for professionals to repair. However, a repair may be a little more costly and time-consuming if the leak results from a pinhole in a refrigerant line.
