4 Air Conditioner Sounds and What They Mean

Are you hearing strange noises when your air conditioner is on? While it’s common for AC units to make a few sounds when running, a loud hissing, buzzing, or clicking noise may indicate something is wrong with the AC unit. If you don’t fix the error soon, it may lead to more significant and expensive issues. 

At Bob Heinmiller AC in the Orlando area, we are experts in Orlando air conditioning repair. Since 1990 we have provided residential and business areas with prompt, professional care. Our in-house technicians and experts have listed some of the most common noises you may hear from your air conditioner and what you can do to correct it. 

Common Air Conditioning Noises and What They Might Mean

  1. Gurgling or running water: a healthy AC unit creates a bit of condensation, which means you may hear a dripping noise from time to time. However, if you hear splashing or running water, it is due to excess condensation from water that has built up in the system and is not draining properly. If you hear this noise accompanied by a leaky or dripping unit, please contact a professional right away. 
  2. Clicking or clanking: this may be a sign of a loose or misaligned part inside the unit. This may be due to the age of the unit, whether or not it was properly installed, or simply a broken part. A clanking sound can also indicate that the fan is out of balance and is now hitting the other parts. If ignored, this problem could cause further damage to the unit. 
  3. Buzzing: when loud enough to become a distraction, a buzzing sound is traditionally an electric issue. This may be due to the contactor relay switch, circuit breakers, fan motor, or other components. If this is the case, you should turn off the unit and reach out to a professional as soon as possible to prevent further damage or injury. 
  4. Humming: while generally not a serious noise, a humming sound can arise from issues with the fan motor. Sometimes, when the home becomes very warm, the fan works harder to remove the hot air from the area. A humming sound may also indicate that something in the unit may be off, such as loose parts or wiring. 

Be cautious if you hear a strange noise coming from your air conditioning unit. If the sound is especially loud or concerning, it’s best to turn off the unit until a licensed professional can take a look. At Bob Heinmiller AC, we realize that Orlando air conditioning repairs can be stressful, but it’s better to correct an issue while it is still manageable.
