An unusual noise coming from the air conditioning system can be worrisome. Although ACs aren't quiet and generate a lot of noise when they're running, there might be a problem if it starts making noises that don't sound right. Luckily, most causes of these noises are simple to fix—and if it needs professional repair, American Air Cares has the tools and know-how to get it done fast.
Some of the noises you might be hearing and their causes are listed below. If your system is making a noise that isn't described below, call us today to schedule an appointment.
If you're hearing a whistling noise, it's possible that the ductwork has a broken seal. This is easily repaired using caulk or heat tape to reinforce the seams.
If you're hearing this noise, it's possible that some screws have become loose and need to be tightened up. Be sure to turn off the power before doing any tightening and call in the professionals if the noise continues.
A thudding noise could mean that a fan blade is loose and thudding as it spins. If this is the case, remember to look over the whole unit to figure out what fell into the unit, if anything, to loosen the blade. Also, you'll need to be sure the system is turned off before any inspections or repairs.
Since air conditioners use belts, a screeching noise could indicate a worn belt that needs to be replaced.
If you hear a repetitive clicking sound while the AC system is running, you need to call a technician right away. This typically means that there is a small obstruction or the fan is loose and knocking against its housing. Though it is safe to run the system if this is the case, you should turn it off to mitigate possible further damage to the system components.
If you are hearing a clicking noise as it tries to turn on, there's an electrical problem somewhere and you need to call in the professionals. It could be a variety of things, including a problem with the compressor or a faulty thermometer. An experienced technician will be able to help diagnose the problem and make any necessary repairs.
