Hvac Clicking Noise In Wall

Hearing an unusual HVAC clicking noise in wall? If you’re hearing strange sounds when your HVAC is running, don’t ignore it! While clicking noises are common and could have any number of causes, louder noises could mean something more serious is wrong. Left unchecked, the problem could get worse over time. In this article, we’ll go over some of the most common sounds that might come from an HVAC system, so you can better understand what’s wrong with yours.

If you hear an HVAC clicking noise in wall…

Is there a fan obstruction? A loose wire or piece of debris rattling around in the fan can cause it to click. In this case, you’ll likely hear the noise every time the fan kicks on. The best way to fix this is to simply remove the obstruction.

Is anything caught in the blades? If something (like a blade of grass) becomes lodged in the fan, it will cause vibrations that result in a clicking noise.

Is there an issue with the capacitor? A bad capacitor could be causing your system to click. Check the capacitor – it is located inside the condenser unit outside your home. To access it, use a screwdriver to remove the side panel. If the capacitor is swollen, black, or leaking, it’s time for a new one.

If you hear a banging noise…

Is something lodged in the ductwork? A foreign object like a screw or washer could be causing the clicking noise as it vibrates through the system. If this is the problem, it’s likely that you’ll also hear a banging noise. You might be able to fix this yourself by reaching up into the ductwork and removing the object, but if you’re not comfortable doing so, call an HVAC technician.

Are there any loose parts? Loose screws, bolts, and other components can create all sorts of strange noises. Listen for rattling, banging, or other sounds that might indicate a loose part. If you identify the source of the noise, try to tighten it yourself. If you can’t, or if the problem persists, call an HVAC technician.

If you hear a humming noise…

Is the sound coming from the inside or outside unit? First, check to see if the noise is coming from the inside or outside unit. If it’s coming from the outside, it might just be the sound of the compressor running normally. However, if the noise is coming from the inside unit, it could be a sign that something is wrong with the blower motor.

In either case, a humming noise is usually not cause for concern. However, if the noise is accompanied by strange smells or smoke, you should shut off the system and call an HVAC technician immediately.

At the end of the day, you HVAC system is meant to help you stay comfortable in your home. Any clicking, banging, or other unusual noise coming from your HVAC system are signs that something isn’t quite right. If you’re ever unsure of what to do, the best course of action is always to call an HVAC technician. They’ll be able to quickly diagnose the problem and get your system back up and running smoothly in no time.
