8 Common Types Of Air Conditioner Noises: Causes & How To Fix

Having air conditioning in your home is the ultimate luxury, especially during hot summer days. However, an AC unit’s constant noises can quickly turn your comfort into anxiety. You may wonder if the noises your air conditioner makes are normal if they are making a lot of noise. Ignoring unexplained AC noises can lead to pricey repairs or a simple tune-up.

If your air conditioner is making strange noises, you may wonder if it’s malfunctioning. To ensure the best performance from your air conditioner, it’s important to have regular maintenance and tune-ups performed by experienced AC Maintenance in Lawrenceville, GA.

Top 8 Common HVAC Noises You Should be Aware of

The sooner you can figure out what’s making the noise and fix your AC, the better. Here’s a list of AC noises and what they mean to help you troubleshoot when your unit makes noise.

  • Clicking noise

When your air conditioner starts and stops, your thermostat may make a sharp clicking sound. A clicking sound during a cooling cycle indicates danger. A relay switch or capacitors in the compressor may be causing the clicking, or a dead thermostat may be clicking.

  • Bussing

If you hear a lot of buzz from your air conditioner, there may be a problem. Electrical issues are almost always to blame. Most of the time, contractors or relays fail. Get in touch with an air conditioning repair in Lawrenceville, GA, as soon as possible to fix the problem.

  • Humming

Capacitor failure can be detected by hearing a humming noise from the air conditioner. The capacitor kicks in when you turn on your air conditioner to get the motor going. Because of the humming noise and the AC’s inability to start up or shut down on its own, this is most likely the cause.

  • Screaming

Call an AC Maintenance in Lawrenceville, GA, if you hear high-pitched shouting. A refrigerant leak will most likely damage your air conditioner and your family’s health. Screaming can signal dangerously excessive internal compressor pressure.

  • Banging

The sound of the compressor banging is usually a sign of a loose or broken part, such as a connecting rod, piston pin, or crankshaft. There might be a chance that your compressor needs to be replaced if you hear a banging sound coming from your system.

  • Bubbling

Your HVAC unit may be making a bubbling or gurgling sound when running because of refrigerant or drainage line problems. Drainage pipe blockages, cracks, and holes are the most common causes of this issue.

  • Screeching

Your HVAC system’s inside or outside unit may make a loud screeching or metal-on-metal noise, which can indicate a problem with one or more of its components. When you turn on your air conditioner and hear a screeching noise, the fan motor bearings need to be replaced.

  • Rattling

If you hear a rattling noise coming from your air conditioner, it could signify that it is beginning to degrade and loosen. They could be to blame if you’ve got twigs or leaves in your digestive system. The screws, bolts, and fan may also cause the problem.
