Likely Causes of Unusual Air Conditioning Noise
Many people can't imagine spending a day indoors during the hot summer season without their air conditioner blowing cool air. That's why it is important for AC users to perform the necessary repairs on their cooling equipment whenever they suspect there is a problem with its operation. Though modern AC units are designed to run as quietly as possible, it is perfectly normal to hear some noise. However, any noise that is new or louder than usual may be an indication that an AC unit is faulty and will need to be repaired.
