Is your condensing unit making noise? Or is it just quiet or maybe even moving in a different direction than you thought it would? If the answer to these questions is “no” then it is time to take a look at what could be causing it. The truth is that it could be anything from poor ventilation or a bad seal around the unit to a cracked duct or even the simple fact that it is not properly sealed at all.
When you get this little problem and the noises from your condensing unit out of the way, the next thing you will need to focus on is the cause of the noise. It could be that it is not getting the air it needs or that a compressor pump is not working properly and causing the noise that you are hearing. There are many reasons why your condensing unit may be making noises but once you have figured out what is causing it, you can just replace whatever is causing it and get it working again.
The second step you should focus on is actually testing the condensing unit to make sure that it is indeed making noise. There are a number of ways that a condensing unit can make noise and it will come down to a variety of things. Once you have tested it for a working pump, you can just close it up and go about replacing any other parts that may be going bad. For example, if it is just a pump then you can check to see if the actuator is working or just the pump. If the pump is not working or the actuator is not working, then that is probably the culprit of the noise.
