It’s important to notice when something is wrong with your HVAC system. Prompt repairs can make a huge difference in both repair cost and system longevity. But “Watch for these signs of AC trouble” or “Keep an eye out for air conditioner problems” are not actually the most helpful things to say when trying to help homeowners keep tabs on their air conditioners.
This is because the most common early indicators that an air conditioner is struggling are not things you can see. Usually, they’re things you will hear. What sounds does an air conditioner make when it needs repair? What do the various noises mean? We’ve got some details for you.
Groaning
The fan that distributes the cool air from your AC unit is powered by a motor. To keep moving smoothly, that motor has bearings in it. With regular lubrication (which is supplied during AC maintenance each year) the bearings can last quite a while. But if you hear a groaning noise, it’s probably the bearings grinding against each other because they’ve gotten worn down. Replace them before you end up having to replace the entire motor!
Rattling
Air conditioners create quite a bit of vibration. Over time, this can loosen all sorts of components. A rattle is generally an indicator that something simply needs to be more firmly affixed into position, which is an easy job for a qualified technician. Don’t put it off, though, because you don’t want a loose screw or fan blade to come free and crash into another component!
Buzzing
Is it bees? Probably not, although it’s not entirely impossible. A mechanical cause of buzzing is that same issue that will lead to rattling—something is starting to come loose just enough to make a noisy vibration. But an electrical buzzing can mean a serious problem that could result in electric shock or fire. If you’re not sure, don’t take the risk. Get help right away.
Banging
If the outdoor unit makes a bang or boom when the compressor first comes on at the start of the cooling cycle, it has to do with the need for a lot of electricity all at once. A hard-start kit or additional capacitor can help provide the high level of power that’s needed to get the cycle started without damage to the compressor, which can happen if you allow the banging to continue.
Bubbling
A bubbling sound can be caused by air in the refrigerant coils. This can only happen if the refrigerant has been leaking out, so it needs to be addressed before enough refrigerant is lost to prevent cooling or cause compressor strain. Other signs of a refrigerant leak can include hissing sounds, chemical smells, ice on the evaporator coils, or poor AC performance.
