Did you know that HVAC systems that are working efficiently should make minimal noise and be relatively silent?
Do not ignore changes in sounds coming from your HVAC system. An HVAC system is supposed to keep your home comfortable. New noises could indicate there is a problem with your system, which could prevent your HVAC system from doing its job.
There are a few common AC noises. A clicking noise is common and could have multiple potential causes. The location of the sound plays a part in determining what kind of problem you are facing.
Here is everything you need to know about that HVAC clicking noise:
What Causes Clicking Noises?
Clicking noises are completely normal if they occur when your HVAC system is turning on or off. A clicking noise when your unit is starting up is caused by your thermostat communicating with your unit. This is not cause for alarm.
However, if you hear loud clicking noises, banging, or clanking while the HVAC system is running, you may have a problem. A constant clicking noise that goes beyond the normal startup clicking is cause for alarm.
A top cause for HVAC clicking noises is fan obstruction. A sign of obstruction is a clicking noise that starts off slow and gets quicker.
As the unit becomes warmer, the clicking noise increases over time. If fan blades are hitting the AC inside, you will hear this clicking noise every time the blade hits the inside of the system. There could be something damaging your blower fan.
If the clicking is coming from outside your house, it is most likely coming from your compressor.
There could also be something wrong with the relay or electrical control. If your HVAC system is making a clicking noise but will not turn on, you could have an electrical problem on your hands.
If there is loud clicking coming from your HVAC system’s cabinet, your capacitor could be on its last leg. A damaged or poorly functioning capacitor could be damaging to your whole HVAC system.
Clicking could also be caused by a defective thermostat.
Clicking when your furnace kicks on for the first time is normal. However, if constant clicking continues to come directly from your furnace, you could be facing an ignition system malfunction.
What to Do About HVAC Clicking Noises
If you are hearing abnormal clicking noises coming from your HVAC system that are not caused by your system turning on or off, you will want to get experienced technicians out to your house.
Experts will be able to diagnose and resolve the issue that is causing the clicking sounds. HVAC clicking noises are almost always a bad sign.
Do not take matters into your own hands when it comes to your HVAC system. Experienced HVAC technicians can determine exactly where the clicking is coming from and which part is causing it. They will be able to provide the necessary repair services.
There are a lot of electrical components to your HVAC unit. It is important to tend to potential electrical issues, indicated by the clicking noises, as soon as possible to avoid having bigger issues down the road. Electrical problems are always a job for a professional.
If you think the clicking noise could be coming from a damaged capacitor or the clicking noise is unsettling, turn off your HVAC unit and call a professional immediately. When the clicking noise is bad, you risk damaging your system’s components by continuing to run your HVAC without addressing the issue.
Annual maintenance and regular tune-ups can help prevent future problems with strange noises. When your HVAC technicians come to repair your system, make sure to ask about a regular maintenance plan.
When to Replace a Noisy HVAC
If clicking is not the only noise you are noticing from your HVAC system, you might want to start thinking beyond repairs and start considering a replacement.
An aging HVAC unit is likely to emit excessive noise. If your HVAC is over ten years old and is making odd noises, you may be better off upgrading to a new unit. A new HVAC system will be quieter and more energy efficient.
If an HVAC professional has determined that the clicking noises are coming from your compressor, you may consider replacement instead of repairs. A compressor replacement is so pricey that it may be more cost-effective to replace your entire system.
You do not have to diagnose whether your HVAC system needs an upgrade on your own. Contact your local technicians for help determining what is necessary. They will help restore the quietness that you should be enjoying from your HVAC system.
