5 Noises That Mean You May Need AC Repair


When you hear an unusual sound coming from your air conditioner, it can be alarming. You know that something is wrong, you just don’t know what it is. Is it something small that can be fixed easily, or is it a larger problem? 

We’re highlighting the top five noises that we get calls about for AC repair in Shippensburg, PA. You can keep reading to learn more about noises that can indicate it’s time to schedule a repair appointment for your air conditioner. Then give our team a call to check out the problem and get your AC back to working at its best.


If your AC ever makes a buzzing sound, you may be tempted to ignore it. Buzzing is not always loud or obvious. But, it is worth paying attention to. If your AC buzzes, there’s a good chance that there is ice developing on the coils.

The buzzing itself is not a problem, but it’s a sign that there is another problem somewhere in the system. Ice can develop in your coils if there is poor airflow or you have a low refrigerant charge. No matter what the cause, our team can check it out and get it fixed.


If you ever hear squealing coming from your air conditioner, that’s a sign that there is too much internal pressure. Your air conditioner has to maintain the right balance of pressurization in order to maintain good airflow and cool your home adequately. If there’s too much pressure in the system, it can add a lot of strain to important components, leading to greater wear and tear and a risk of breakdowns.


If a refrigerant leak is a problem for your air conditioner, you may hear a hissing sound. Refrigerant is often in a gas form inside of your air conditioner, and if there is a hole in the line, the refrigerant will make a hissing sound as it escapes. This isn’t just an inconvenience because of the lack of cooling. It’s also dangerous for your family’s health and poses hazards for your home as well.


Grinding sounds can be the loudest and most obvious noises when it comes to AC problems. Grinding can sound like metal on metal because that is exactly what’s happening. Parts can get slightly out of place or lose lubrication and begin grinding together instead of flowing easily. Our team can find the source of grinding and repair or replace the parts that are affected.


When you hear rattling coming from inside your AC unit, that’s a sign that a part is loose. It may simply be loose, but still intact and knocking against other parts. But there’s also a good possibility that a screw or bolt broke off and is knocking around. This is a problem because it can damage other parts and cause even bigger problems.
