Listen for These Warning Sounds From Your AC

woman-listening

If you have your home’s air conditioning system professionally maintained before summer arrives (and it’s not too late to schedule it with our team!), you can expect to have few troubles with keeping your house cool when the hot weather settles in. 

However, no amount of maintenance can prevent all AC troubles, and we recommend you keep an eye out for warning signs something is wrong. Or, in this case, keep your ears open…

Strange noises are one of the easiest ways to detect a faulty AC so you can take action. The sooner you call our technicians for air conditioning repair in Conyers, GA, the easier the problem will be for us to solve—and the less likely you’ll get stuck with a non-working air conditioner on a hot summer day.

The Common AC Warning Sounds

Modern air conditioning systems are designed to run at quiet levels. You should only hear quiet whirring sounds of motors and fans from your AC, with the occasional drip of condensate moisture. Anything loud or unusual is a reason for concern. Here are the sounds to listen for and what they may mean:

  • Grinding: This often indicates an issue with the motor’s bearings. If the bearings are worn out or malfunctioning, the motor might need to be repaired or replaced to prevent further damage to the system.
  • Hissing: A hissing noise can be a sign of a refrigerant leak. This is a serious issue because it can reduce the efficiency of your AC and potentially cause damage to the compressor if not addressed promptly.
  • Banging or Clanking: These sounds typically suggest a loose or broken part inside the compressor. This could be a sign that the compressor itself is failing, which is a significant issue that requires immediate attention.
  • Screeching: A screeching sound often comes from issues with the fan motor or a problem with the belt that connects the motor to the fan. This could indicate that the fan motor needs lubrication or the belt needs to be replaced.
  • Buzzing: Buzzing noises can come from several sources, including loose parts, debris in the unit, or electrical issues such as a malfunctioning relay switch. It’s important to have a professional inspect this to pinpoint the exact cause.
  • Clicking: While it’s normal to hear a clicking sound when the AC turns on and off, continuous clicking might indicate a problem with the thermostat or a failing capacitor.
