When your air conditioner starts making a new or unusual noise, it’s easy to feel a little concerned. While some sounds are completely normal, others can be red flags that your system needs professional attention. As your trusted HVAC company in Bakersfield, we want to help you understand what your air conditioner is trying to tell you. This guide will provide some high-level tips for troubleshooting common air conditioner sounds, but remember that the safest and most effective solution is always a professional AC repair from the team at Gundlach’s Plumbing & Sheet Metal Co. Ltd.

Banging or Clanking

A loud banging or clanking sound from your air conditioner often indicates a loose or broken component inside the unit. This can be caused by a disconnected part in the fan motor, a failing compressor, or even a loose crankshaft. Continuing to run your unit with a banging sound can lead to more serious and costly damage. Our best advice for homeowners in Kern County is to immediately turn off the system and contact us for a professional diagnosis to prevent further harm.

Squealing or Screaming

A high-pitched squealing or screaming noise typically signals a problem with the fan motor’s bearings or a worn-out belt. These sounds can be piercing and should not be ignored. A failing motor could seize up completely, leaving you without a working air conditioner when you need it most. This is not a sound you should try to ignore. For reliable AC repair in Bakersfield, shut down your system and let our certified technicians handle the problem safely.

Hissing or Gurgling

Hissing or gurgling sounds are often the most concerning because they can indicate a refrigerant leak. Your air conditioner uses refrigerant to cool the air, and a leak can harm both your system’s performance and the environment. This is a serious issue that requires immediate professional attention. Never attempt to handle or top off refrigerant yourself. If you hear a hissing noise, call Gundlach’s for a thorough inspection and expert repair to restore your system to perfect working order.

Clicking

Clicking sounds can be normal during the start-up and shutdown cycles of your unit, but if you hear a persistent clicking sound while the fan is running, it could be a sign of a more serious issue. This could be an electrical problem, a failing relay, or a loose obstruction within the fan. While minor clicks might not be alarming, a constant clicking sound can signal a component failure on the horizon. Our team provides comprehensive HVAC troubleshooting to accurately diagnose and fix the issue.

Buzzing or Humming

A buzzing or humming noise is often electrical. It can stem from a loose fan blade, a failing motor, or an issue with the electrical wiring. You can perform a simple check for any loose debris or twigs caught in the fan, but if the buzzing continues, there may be a serious electrical issue that needs attention. Given the risks involved with electrical components, we always recommend you contact a professional AC repair service in Bakersfield, like ours, for a safe and effective solution.
