Why Is My Air Conditioner Making a Rattling Noise?

AC Making Rattling Noise

As the summertime arrives again, many of us will turn to our air-conditioners to ease our discomfort. However, like any machine, your air conditioner could stop working optimally at any time. Sitting in the summer heat with an air conditioner that is not working is inconvenient and infuriating. One of the most tell-tale signs of an inefficient air conditioner is that the air conditioner makes rattling sounds. Negligence or ignoring the sound could lead to the entire air conditioner needing repair or even replacement.

 If you notice your air conditioner is making a rattling sound, it could be due to the following reasons:

  • Loosely screwed panels
  • Motor malfunction
  • Dirt and debris
  • Damage to the fan blade

You should call a trusted air conditioner repair, in The Villages, and Florida, immediately if you notice anything wrong with the air conditioner. 

Here Are the Possible Reasons Your AC Is Making A Rattling Sound:

  • Loosely Screwed Panels

One reason for a rattling sound is that the screws of the air conditioner are not on as tight as they should be. It could be due to the screws loosening over time or because they were not screwed tightly, to begin with. You can rectify this by yourself by screwing the loose screws. However, if the noise continues, you should look for an appropriate AC tuneup in The Villages for a thorough examination of your unit.

  • Motor Malfunction

Your air conditioner runs on many motors working harmoniously. However, if the motor is damaged, loose, or is not working properly, it could result in a rattling noise. If you notice a malfunctioning motor while troubleshooting, you should hire a professional AC service in The Villages to fix it immediately. 

  • Dirt and Debris

Over time, the air conditioner accumulates dirt and debris. This does not only cause a rattling sound, but over time if a lot of dirt and debris gets accumulated, it could cause permanent damage to your HVAC system. 

 You must avoid getting dirt or debris in your air conditioner by clearing the space around it. During the summertime, the grass and trees grow too. Trimming the foliage near the air conditioner will significantly reduce the debris accumulated in your air conditioner. 

  • Damage To The Fan Blade

Ideally, when everything is in sync, the fan blade is working harmoniously with the rest of the air conditioner, and there is not much sound created. A rattling sound could also be due to the fan blade hitting against other parts of the air conditioner or due to debris. It could also be due to the bad alignment of the fan blade due to improper installation. You should opt for repair if you notice a fault in the fan blade.
