Does your air conditioner make weird noises, there might be something wrong with it that needs to be repaired. Noises from your cooling unit can tell you a lot about its health and help you identify the components that may be problematic. Ignoring the sounds and leaving the problems untreated can lead to bigger problems and costly repairs and replacements.

If you’re annoyed by your talking air conditioner, here is how you can figure the problem on time and get it fixed by a professional.

Gurgling sounds

Gurgling noises are usually an indication of a problematic refrigerant. However, a refrigerant line is a complicated mechanism, and it can be challenging to find out where the noise is rooting. It’s better to call an HVAC specialist and tell them about the noises so that they come to visit you for an inspection and an air conditioner repair service.

Crackling Sounds

A crackling indicates that there is dust or debris in the unit, or the ductwork is getting old. If you hear crackling noises outside your home, it means the debris is stuck inside the exterior unit. However, the noise inside your home is an indication of aging and worn-out ductwork. In either case, schedule an appointment with HVAC contractors for required maintenance, repairs, or replacements.


Hissing is a common indication of a cracked refrigerant line, a leaking internal valve, or a leaking compressor. All of this can lead to inefficient cooling and air regulation inside your home. Because of this, your thermostat won’t be able to gauge a stable indoor temperature, and your air conditioner will continue to overwork and consume more energy.

Buzzing Noise

Buzzing isn’t an indication of a problematic air conditioner or any other HVAC component. It usually occurs when there’s an issue in the network of electric wires around your home. Immediately call an electrician if you hear a buzzing sound anywhere in your home.

Pulsating or Clicking Noise

These noises are usually a sign that the air conditioner’s fan or some other part is loose or misaligned. Turn off your air conditioner as soon as you notice a pulsating or clicking noise and schedule for an emergency HVAC repair.
