My HVAC compressor was making so much noise that I had to call my HVAC supplier
Although the compressor is under warranty regardless of how quickly I addressed the issue, calling before it failed entirely meant that I could get the repairs done before losing access to a/c for a day or longer
If a machine is making excessive noise, you should turn it off regardless of what it is. I saved my old SUV from an early demise when I pulled off to the side of the interstate after hearing crazy noises coming from the engine. If I had kept driving, I probably would have fried the engine and totaled the car. Even though I don’t know anything about car engines or how to troubleshoot them, it seemed like something was seriously wrong when I heard those noises that day. This mindset should be applied to all mechanical machines, even a computer harddrive with a moving disc inside. If you’re hearing noises that you’re not accustomed to with everyday use, you need to stop and get the help of a professional. I was hearing strange noises with my HVAC compressor outside whenever the whole system was cycling. It was the worst when the condenser would start to turn on, but I was hearing the noises at random times during the cycle as well. That’s when I decided to call my heating and cooling supplier, as there was no sense in letting the equipment fail and break further. I don’t know enough about HVAC systems to make a judgement call like that, so I called my HVAC company right away. I’m glad that I did because the compressor needed to be fixed right away. Although the compressor is under warranty regardless of how quickly I addressed the issue, calling before it failed entirely meant that I could get the repairs done before losing access to a/c for a day or longer. And if this repair is planned out, you can choose the best day to have the job finished.
