Servicing Pasco, Pinellas, Hillsborough, and Hernando Counties

Modern air conditioners now operate more quietly than ever. Two-stage compressors and sound-dampening technology ensure noise levels remain quiet in high-efficiency AC units. If you notice strange sounds coming from your air conditioner in Hudson, FL, it’s important to pay attention and take appropriate action.


Banging sounds often indicate a broken or a loose part inside the air conditioning compressor, such as a crankshaft, piston pin or connecting road. In some cases, banging noises may result from an unbalanced indoor blower. Your system may require a compressor replacement.


Clanking sounds may also indicate that a part has failed or is out of balance. This sound may also indicate the failure of the compressor. You may also hear clanking from out-of-balance blades.

If ignored, these problems will only become worse over time. To avoid even bigger problems, schedule an appointment with an air conditioning service specialist to diagnose the issue.


It’s normal to hear some clicking from your system as part of the regular start-up and shutdown process. However, continual clicking is not normal. Such continuous clicking may indicate a failure of the thermostat or control.


If you notice buzzing coming from the outside unit, there could be several reasons:

  • Debris
  • Loose parts
  • Out of balance or loose fan blades
  • Loose outdoor fan motor
  • Out of balance blower
  • Refrigerant leaks

Depending on the severity and the location of the refrigerant leak, you may or may not notice any accompanying sounds. However, if you notice that your unit is running outside, but it doesn’t seem to be cooling inside, it’s time to call a professional.


You may hear loud squeals or squeaks when the indoor blower or outdoor fan motor is going bad. Although some rattling or squealing may be normal when the unit starts, if you notice a new sound, it’s important to get it checked out.
