4 Common Air Conditioner Noises and What They Mean
When it comes to the air conditioner in your Jacksonville, Florida, home, there are many sounds you are likely to hear. Some of these will be normal and indicate that the unit is functioning correctly, while others will be clear signs that something is wrong. We will take a look at four of the most common air conditioner noises to help you understand what they mean.
Squealing or Screeching
If you hear squealing or screeching sounds coming from the blower motor, your AC could have a bad belt or motor bearing problems. Although serious, this issue can be fixed easily by replacing the belt or by adding lubricant to the motor. Just don’t wait too long to contact your contractor about this problem. If the belt or motor completely malfunctions, your blower will no longer work and will require more effort and money for repairs.
A fast “thwapping” noise when the blower runs could indicate that something is stuck in the blower blades or a component surrounding the blower blades. This isn’t a serious problem, but if an object creates too much resistance in the blades, it will wear out the motor faster than normal. If you are concerned about this sound, consult with your technician during a normal HVAC preventive maintenance appointment.
Some clicking sounds are normal when your air conditioner turns on and off. However, if you hear repeated clicking coming from the control panel or outside compressor, you may have a defective relay. This is often due to a faulty electrical control and will require a professional fix.
Banging or Clanking
Banging or clanking sounds can be very alarming and may often signal a loose component inside the air compressor. If you hear these sounds, contact an HVAC technician immediately. Your AC unit could need a new compressor or motor to continue functioning normally again.
Your air conditioner will always make some noises. If you ever hear new sounds or sounds that don’t seem normal, it could be an indication that your air conditioner needs to be repaired. To be certain, contact Mike Merritt Heating & Air at 904-262-5926 to speak with an expert.
