Air Conditioner Sounds You Should Never Ignore

Have you noticed any air conditioning problems this season? As we are well into the summer heat, hopefully the answer to this is no, since you are relying on your system just about every day. Of course if you do experience any air conditioning problems, our team is here to assist. But how exactly do you know when it’s time to give us a call?

One of the most common signs that something is wrong with your AC system is weird sounds. No air conditioner is ever going to be silent of course, but if you notice sounds that are unfamiliar to anything you’ve heard before, then repairs—or an inspection at the very least—are most likely needed.


If the sound you hear coming from your air conditioner resembles hissing, you probably don’t have to worry about a snake sneaking around. Rather, you should be concerned about your refrigerant. This heat transfer fluid is responsible for enabling your air conditioner to cool your home, and a hissing sound means that it is leaking from the system.


Sometimes you might hear a slight banging noise as your system starts up due to your air ducts expanding and contracting with temperature fluctuations. If this turns into a loud and consistent banging every time your AC is running, however, then it may be the sign of a loose component or bent fan blade.


This is one noise that should never be ignored. It’s generally associated with electrical problems such as a faulty relay or a failing capacitor. There are a number of issues that can cause this noise or cause electrical issues. No matter what you think the cause is, this type of noise should be investigated by one of our professionals right away for your safety.
