Loud Air Conditioner? Here’s Why Your AC Is Knocking
Are you struggling with a loud air conditioner?
AC units are complex. Loud noises from your unit could mean there’s some dust stuck inside or you need to replace one of the major coils.
We understand how annoying and embarrassing this can be to deal with. So, we compiled this guide to help you figure out what could be wrong with your unit based on the sound it’s making.
Why Do I Have a Loud Air Conditioner?
There are several reasons your air conditioning unit could be making loud noises. One thing you shouldn’t do is ignore the noise.
In fact, the noise is a sign there is a problem with your unit. A professional can use the sound to diagnose what’s wrong.
Before calling an HVAC company like J&M Smith Heating and Air, you can try to check out the unit yourself.
Here are some simple reasons for a loud AC:
- Your air conditioning fan may be dirty or broken
- Your AC motor may need lubrication
- Screws inside of your unit could be loose
- Your coil fin may have dirty
If you try each of these solutions but the problem persists, call a professional as soon as you can.
What To Do if Air Conditioner Is Making Loud Buzzing Noise?
One of the most common issues we hear from customers is about their air conditioner making buzzing noises. What does this mean exactly?
Buzzing from the outside unit could mean there are loose parts or it has debris stuck inside. On the other hand, a buzzing noise inside could be something as simple as needing to change an air filter.
Other possibilities — that are more serious and more expensive — include an out-of-balance blower or a faulty condenser coil. You also may be experiencing electrical problems or your copper lines are rubbing against other materials.
Our customers frequently hear humming, clicking, squealing, screeching, rattling, or hissing from their units. Each sound comes with its own issues to replace or repair.
When Your Air Conditioner Makes a Loud Noise When Turning on
Another concern we hear from clients is why their air conditioner makes a loud noise when starting?
Unlike the other noises, which could be dirt, an old filter, or loose screws, hearing loud noises when the unit starts means you’ll have to repair your compressor motor. This part is important for keeping your house cool.
Wondering how it does that? A blend of chemicals known as refrigerant moves between liquid and gaseous states. A compressor is responsible for circulating the refrigerant through your AC system.
