It’s August in Indiana, and that means two things: high temperatures and overworked air conditioning units. We depend on our AC units to keep us cool as the summer sun shines down, and most of us can’t tolerate having to wait a few days without it if our units fail. The best way to keep your AC running is to get it regularly serviced, as well as looking out for any signs that may mean there’s a problem. If you notice strange sounds coming from your unit, it may be time to call a professional. Here are the sounds you need to look out for.
Repetitive clicking sounds from your compressor
AC units usually make clicking noises when turning off and on. If you hear repetitive clicks, there may be a problem in an electrical control or a defective relay, keeping your AC from starting properly.
Rattling sounds from your AC fan
Your fan unit and compressor (that big unit outside your home) should run relatively quietly, with the only sound being air moving through the system and fan blades turning. If you notice loud rattling coming from the unit, it could be cause for concern. This typically means some sort of loose hardware or a failing motor.
Your Air Conditioning squeals or screeches
Though a somewhat rare occurrence, a squealing or screeching sound from your AC is likely caused by a failing belt or motor bearing. This is caused by a lack of lubricant or oil reaching these parts, causing them to dry and decay in quality. Fortunately, these are typically inexpensive repairs.
A “flapping” sound when your blower is running
If your AC fan is on and you continually hear a flapping sound (like a waving flag or like a playing card stuck in bike spokes), something is likely stuck in the blower blades, or something in the unit making contact with the turning blades. These problems can almost always be solved easily and are usually not cause for concern, but certain impediments can damage fan blades if left unattended.
Loud Thumping or Banging Noises
If your AC unit regularly makes loud banging noises, it usually points to a piece of your blower or motor coming loose. Any loose part should be addressed immediately, lest further damage occur to your system. Call a qualified AC technician immediately and get your problem solved.
