Clanging or clicking noises when you turn on your air conditioner is an indication of damage within the HVAC system. If the noise is generated every time you turn on your unit, and you can’t determine the source, it’s time to call an HVAC specialist.
Banging & Clanging
When you start your unit, you may hear a loud pounding sound. This might be an indication of debris within the unit. If it isn’t debris, it’s most likely a loose fan hitting the HVAC cage. If you hear this noise from your device, turn it off right away. If you continue to use the system, it may cause more damage to your unit.
If your device produces a screeching noise, as if the metal is scraping against metal, this might be an indicator that your fan motor bearings have failed. This isn’t a life-threatening emergency, but keep your unit turned off until you can get an HVAC professional to look at it.
If your device makes clicking sounds when you start it but never turn it on, you may have an electrical problem. You shouldn’t attempt to solve this problem on your own. Otherwise, you might end up ruining your system.
Common Fixes To Loud Noises In Your AC System
You may regularly implement a few simple adjustments to reduce annoying sounds emanating from your A/C unit.
Coil Fins Should Be Cleaned and Straightened: Maintaining your unit’s circuit fins can enhance efficiency. Straighten coil fins using a fins comb and clear up any residual dirt with a vacuum.
Loose Screws Should Be Tightened: Running vibration might cause screws within your machine to loosen. This might create rattling during operation, but it can also lead to loose parts within the system over time. During routine maintenance visits or when attempting to fix a noise problem, have all loose screws tightened.
Remove debris found in the blades: When you open the A/C cabinet, look for any residue on the fan. Remove any debris from surrounding the fan blades to minimize banging and clanging noises from your unit as it boots up. This is a very simple repair that should only take a few minutes.
