It\u2019s 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 \u201cWatch for these signs of AC trouble\u201d or \u201cKeep an eye out for air conditioner problems\u201d are not actually the most helpful things to say when trying to help homeowners keep tabs on their air conditioners. <\/p>\n\n\n\n

This is because the most common early indicators that an air conditioner is struggling are not things you can see<\/em>. Usually, they\u2019re things you will hear. For example, these sounds mean trouble for your AC<\/a> and should never be ignored. What sounds does an air conditioner make when it needs repair? What do the various noises mean? We\u2019ve got some details for you.<\/p>\n\n\n\n\n\n\n\n

Groaning<\/h2>\n\n\n\n

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\u2019s probably the bearings grinding against each other because they\u2019ve gotten worn down. Replace them before you end up having to replace the entire motor!<\/p>\n\n\n\n

Rattling<\/h2>\n\n\n\n

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\u2019t put it off, though, because you don\u2019t want a loose screw or fan blade to come free and crash into another component!<\/p>\n\n\n\n

Buzzing<\/h2>\n\n\n\n

Is it bees? Probably not, although it\u2019s not entirely impossible. A mechanical cause of buzzing is that same issue that will lead to rattling\u2014something 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\u2019re not sure, don\u2019t take the risk. Get help right away.<\/p>\n\n\n\n

Banging<\/h2>\n\n\n\n

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. This may be a sign of a hard-start problem causing AC issues<\/a>, which can be remedied with a hard-start kit or additional capacitor. A hard-start kit or additional capacitor can help provide the high level of power that\u2019s needed to get the cycle started without damage to the compressor, which can happen if you allow the banging to continue. <\/p>\n\n\n\n

Bubbling<\/h2>\n\n\n\n

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. You can learn more about the refrigerant misconception and replacement options<\/a> if you\u2019re dealing with persistent leaks or refrigerant-related problems. Other signs of a refrigerant leak can include hissing sounds, chemical smells, ice on the evaporator coils, or poor AC performance.<\/p>\n\n\n\n

Play It Safe<\/h2>\n\n\n\n

When in doubt, don\u2019t hesitate. Any unexpected sound from your air conditioner is a sign that you need AC services in Ashburn, VA<\/a>. So even if you hear something that\u2019s not on this list, get repairs before the problem gets any worse.<\/p>\n\n\n\n
