Why is My Air Conditioner So Loud? How to Fix a Noisy AC

When someone asks us, “why is my air conditioner so loud?”  I often respond with, “why is your truck so loud?”  Just as with your truck, a noisy air conditioner is a complex piece of machinery with many moving parts, all of which interact with each other.  So, figuring out why your air conditioner is so loud is far too complex a question to address all in one article, so we will instead focus on a few of the most common causes for a noisy AC.  Just as with your car, if it starts to make a harsh, grinding sound, then it’s probably best to leave it to a licensed HVAC technician.  But that does’t mean you should rush to your phone the second you hear your HVAC unit squealing.  Those of you who read our articles regularly, know that we are a small, U.S. Veteran-Owned HVAC company in Southern California, and pride ourselves in giving people honest, straight answers to their questions.  Case-in-point, often times you can avoid a costly AC repair and fix your own noisy air conditioner; we aim to help you do just that.  In general, a change in the way your AC sounds is a bad sign, but that does’t mean that it isn’t an easy fix.  Here are a few things for you to think about when your air conditioner gets loud, most of which you can do yourself with just a little bit of time and some basic household tools.
