• Modern air conditioners are designed for quiet
  operation. The variable speed compressors and
  sound-dampening technology found in
  high-efficiency AC units typically keep noise
  levels below 55 decibels. Just like pain is a
  warning sign that your body is suffering an
  injury, unusual sounds coming from your air
  conditioner are a sign of impending common AC
  problems and should be addressed immediately.

• These sounds are usually signs of a loose or
  broken part inside the compressor, motor, or
  blower assembly. They could also be an indication
  that the indoor blower is unbalanced or that the
  motor mounts are loose.

AIR CONDITIONER PROBLEMS THWAPPING
This sound is best described as being similar to
the one made by the playing card that you would
stick in the spokes of your bicycle tires as a
child. This is usually an indication that
something is stuck in the blower blades or that
something inside the housing is coming into
contact with the blower as it rotates.

• A clicking sound as your HVAC units turns on and
  off is normal and not a cause for concern.
  Repeated clicks from the control panel or
  compressor, however, may indicate a faulty relay.
  It could also be caused by a malfunctioning
  thermostat.

AIR CONDITIONER MAKING BUZZING SOUND

• A variety of issues could cause your outdoor
  unit to start buzzing
• The fan blades or other parts may be loose or out
  of balance.
• There may be debris in either the indoor or
  outdoor unit.
• The air filter may be dirty and need to be
  changed.
• The condenser coils may need to be cleaned.
• The blower or fan motor could be about to fail.
• The copper refrigerant lines could be rubbing
  against something.
• It could also be a sign that you have a
  refrigerant leak. If this is the case, you will
  notice that your AC is only blowing warm air. If
  not addressed, a refrigerant leak can eventually
  cause your AC to freeze up.

• The fan motor, compressor, blower motor, and
  blower wheel and housing can all start to squeal
  when they malfunction. Squealing and screeching
  can also be a sign of less serious problems, such
  as a worn belt or a problem with the motor
  bearings. The sounds can also be an indication
  that the blower motor unit simply needs
  lubrication.
• If the sound is more of a high-pitched scream or
  whistle, there is a good chance that you have a
  refrigerant leak. This is caused by a buildup of
  pressure within the compressor. This can
  seriously damage your air conditioner and is a
  dangerous situation for your family. You should
  turn your AC off immediately and contact a repair
  professional.

HUMMING OR HISSING

• The refrigerant piping or loose parts can
  occasionally cause an air conditioner to hum or
  vibrate. It can also be a sign of electrical
  problems or a capacitor that is failing. If the
  humming is coming from a compressor that refuses
  to start, there may be an issue with the motor.
• If you hear a hissing noise inside the walls of
  your home, you may have a leak in your ductwork.
  The sound occurs as air escapes from the system.
  Although not a dangerous situation, leaking
  ductwork is wasteful since the cool air that you
  are paying for is being lost inside the walls
  instead of being directed into your home. A light
  hissing sound coming from the vents is usually a
  sign that your filter is the wrong size or is not
  positioned correctly.

AIR CONDITIONER MAKING RATTLING OR TAPPING NOISE
Air conditioner rattling is typically an
indication that there are loose or deteriorating
parts. There may also be leaves, twigs, or other
debris clogging up the system. A tapping noise
could also be the result of a defective
electrical contactor.
