Sounds You Never Want to Hear from Your AC Unit

The more wear and tear that your air conditioner endures, the more likely things are going to start failing. In some cases, these issues will require some level of repair but these are relatively simple and affordable to repair.

But there are some issues that might occur with a unique sound accompanying their arrival. These are the sounds you don’t want to hear from your ac unit, however if you do, you’ll need to call in a reliable service shop dealing with heating and air Chesterfield. Fortunately, some of these sounds can be prevented with routine care and maintenance administered to the system. It’s a good idea to get into the habit of servicing your ac unit at normal intervals, that will allow you to preserve its lifespan and get more out of your air conditioner

So, let’s take a look at all of the most common the noises, both benign and otherwise, that may be coming out of your air conditioner and the issues that may be troubling the system.

Bubbling Noise

When you hear something like this, it means your system is probably low on refrigerant. There could be a leak some place and it needs to be diagnosed and fixed. You will need to call a professional repair company to have a look, this isn’t something you can figure out on your own.

Humming Noise

When most air conditioners are emitting a low hum sound, it typically means the system just needs to be cleaned. The cause is often some dust or dirt that’s got into the unit and all you need is to get in there and wipe the interior of it down with a dry cloth or towel.

Banging Noise

This is one of those noises that sounds pretty bad but it may not be as bad as you might think. In most instances, something in the system has come loose or fallen off. You may be dealing with a simple fix like a loose screw or a more complicated problem like a fan or blower that been damaged.

Squeaking Noise

Squeaking is not good. You may hear this when your motor is starting to malfunction or a fan belt is coming loose. You’re hoping for the latter, that’s a cheap and easy repair. Fan belts will contract and expand with changes in the weather and eventually they can start to slip or snap entirely. The former is going to require a total replacement of the motor and it will cost significantly more than swapping out a fan belt.

Whistling Noise

If you’re getting a whistling sound out of your air conditioner, that is a sign of an airflow problem. You’re not getting enough of it through the system and this can overtax the air conditioner. This low air distribution problem could be due to any number of reasons, from an air filter that needs to be replaced, a shut damper, there is a leak somewhere in your ductwork, or your blower is beginning to fail.
