# Central AC Making Strange Noises? Here’s How to Fix It
Dealing with loud and irritating noises from your Central AC system can be frustrating and hard to troubleshoot. Fortunately, the root cause of these noisy malfunctions can often be traced to common issues that are easily fixed. Whether your system is turning itself off or making strange noises, our guide is designed to help you identify and correct the underlying issue.
In this article, we’ll review some of the most common Central AC noises and their causes. If you suspect there may be a more serious issue with your system, we’ll also provide helpful advice on when to call in a professional. Let’s get started.
## Strange Whistling Sounds
First-time homeowners and experienced alike can be startled by the sudden appearance of strange whistling noises coming from their Central AC system. Typically, this sound is indicative of air supply problems due to clogged air filters or blocked air vents.
In order to address the underlying issue, first check around the building for any evidence of blocked vents. If any are found, be sure to clean them properly as soon as possible.
You should also clean or replace your system air filters as needed. If either of these solutions does not work, you may need to adjust the speed of your fan motors. Reducing the airflow may help reduce the sound. Finally, check for any problems with the system’s ductwork, such as disconnected or degraded ducts.
## Rattles and Ticks
Rattles and ticks are noises that often come from a central AC system’s fan motor or blower unit. If these noises persist, you may need to lubricate the motor to reduce the amount of friction and wear. In addition, you should check the fan blades for signs of deterioration or any foreign objects caught in the blades. If you detect any obstructions, be sure to remove them to reduce noise and improve system performance.
## Humming
The hum of a working system is often an indication that all components are in good working order. However, if the hum is louder than usual or accompanied by a vibration, you may need to check the system’s bearings. Listen for any inconsistencies in the sound that may indicate a misalignment or malfunction.
In most cases, the bearings only require lubrication to reduce noise and improve operation. However, more serious malfunctions may require a complete motor overhaul or replacement of the motor itself.
## Buzzing
If your central AC system is producing a buzzing sound, it’s likely due to vibration of loose or misaligned parts. Inspect the system to locate the source of the vibration and address any issues immediately. You may need to check, adjust or tighten system components, such as fan blades and blower housings. In some cases, loose or worn fan bearings may need to be replaced.
## Whines
Whines and squeaks are typically caused by worn or damaged fan motors. To resolve this issue, you’ll need to inspect your system for loose or worn out parts and adjust or replace them as needed. But before attempting any repairs, be sure to turn off the power to the unit and take appropriate safety measures.
## Wrapping Up
We hope that this article has helped you identify and remedy any strange noises coming from your Central AC system. If you’re still having trouble locating the source of the issue or if any of the corrections seem overwhelming, we recommend calling in a professional to inspect and repair your system.
