Why Is My AC Making Weird Noises?


New, technologically advanced air conditioning units are designed to be extremely quiet. Most will make little to no noise at all. When you hear noises coming from your unit, listen closely to the sound and where it is coming from. As soon as you notice any new noise, you need to call your air conditioning professionals at Iceberg Home Services. We will diagnose the problem and get your unit back on track in no time. The following noises may be a cause for concern:


A buzzing noise can mean many things ranging from an electrical problem to fan blades that are out of balance. It can also mean condenser coils that are either dirty or damaged. Fan motors may also buzz if they are damaged in any way.


A dripping noise may mean that condensation is building up on your air conditioner’s coils and running off. While this may occur naturally during periods of weather where the humidity is excessively high, it isn’t normal when the humidity is lower. Whenever you hear a dripping noise in or near your air conditioner, you need to call your HVAC professional at Iceberg Home Services.


In most cases, a hard banging noise is often associated with the compressor of your air conditioning unit. Your compressor is constantly moving air from your home through the AC unit. As it ages and parts start to wear out, you may hear loud bangs or knocks as the parts loosen and begin to move around.

Clanking or Clicking

Clanking or constant clicking that occurs toward the beginning or near the end of your AC cycle may indicate a faulty thermostat. You may eventually begin to experience a lack of cooling or an extreme drop in temperature if the thermostat malfunctions and won’t turn the unit off. The clicking may also indicate a malfunction in the wiring of your AC unit.


A screeching or squealing noise is often the result of a malfunction within the fan motor of your air conditioning unit. As the fan motor begins to wear out, the friction within will create a high pitch squealing or screeching noise that will only worsen over time until the motor eventually just stops working altogether.


Humming noises are sometimes the result of a faulty relay switch that doesn’t send the message from the thermostat to the condenser motor. The hum may continue to worsen over time or simply stop working as it begins to get hot. A hum may also be a sign of a faulty fan motor that doesn’t kick on or turn off properly.


In the majority of cases, rattling may be an indicator that a fan blade or other moving part is bent or broken. If you can see what is causing the noise, don’t try and fix it yourself. Call the HVAC professionals at Iceberg Home Services who have the equipment and the skills to make sure the job is done right the first time.
