3 AC Noises You Can’t Afford to Ignore in Bunn, NC

Since ACs tend to be rather quiet, hearing the system in your home in Bunn, NC suddenly begin making loud noises is cause for alarm. While a quiet hum is normal, if you hear any of these three sounds coming from your AC, you shouldn’t ignore them.

1. Whistling or Squealing

A piercing whistling noise coming from your AC typically means one of two things. Either refrigerant has leaked from your system, or there is an inordinately high level of pressure in your system’s compressor. Either issue is quite dire, so you should immediately turn off your AC and call for professional help.

Squealing noises, which may sound similar, may point to some other kind of pressure issue in your AC. Usually, it means that the fan motors or blower motors in your system are going bad. You’ll need repair or maintenance services from an HVAC technician to take care of this problem.

2. Banging or Rattling

These noises typically emerge only after you’ve had your AC for several years and the system’s parts have begun breaking down. The parts in question may be things like piston pins, crankshafts or connecting rods in the compressor. Debris such as pebbles or twigs may also rattle around there, or it might be that one of your system’s fan blades has come loose.

3. Clicking

It’s normal to hear a clicking noise at either the beginning or end of a cooling cycle. However, the sound should not persist through the cycle. If it does, the system’s capacitor may be losing its electrical charge, or there may be other electrical issues that inhibit power from flowing.

Alternatively, one of your AC’s fans might be loose, or some sort of foreign object may have gotten caught between the fan blades.

Don’t ignore any of these sounds coming from your AC. Instead, call Alford Mechanical and get the best AC repair services around Bunn, NC.
