When your air conditioner is on and running, it makes a few sounds that are completely normal. Most sounds happen as your unit is starting up or turning off. Noises that are minimal don’t usually signal that anything is wrong, but other sounds can be cause for concern. If you’re not sure about the sounds coming from your AC unit, always get it checked out.
As a general rule, there are five sounds that your AC unit should never make. Hearing an unusual sound is a sign that something is wrong, and you should reach out to a professional as soon as you can. A certified technician has the expertise to identify the problem and fix it. Ignoring concerns can lead to permanent damage to your air conditioning unit.
