Strange noises coming from your air conditioner are never normal. Often, they indicate a malfunction and a need for air conditioner repair. While calling your contractor should be the first step after discovering a new sound, identifying the potential cause of noise could help you prepare for necessary repairs. Explore a few everyday AC noises and what may cause them below.

What the Sounds Coming From Your AC Mean

1. Hissing

A loud, high-pitched hiss or screech could be the result of a compressor problem. The cause could be a refrigerant leak or a high internal pressure within the compressor, both of which are dangerous if left unaddressed. Turn the system off immediately and call for air conditioner repair.

2. Clanking or Banging

These mechanical noises typically indicate a loose or broken component within your network. Sometimes, parts such as piston pins and connecting rods can come loose within the compressor. It’s also possible that you need to balance the blower.

3. Buzzing

Homeowners sometimes notice buzzing noises originating from their outside unit. There are many potential explanations for this, only a few of which require air conditioner repair. For example, the system may need condenser coil cleaning or a new air filter. However, you should still leave the diagnosis to a professional.

4. Gurgling or Wet Noises

There are generally only two explanations for water-like sounds emanating from an AC: there’s something wrong with the refrigerant or condensate line. Both are serious if left unaddressed, potentially resulting in issues such as corrosion or the entire system shutting down.

5. Rattling

AC units have a finite lifetime, and rattling noises typically point to a deterioration of internal components. When this happens, debris may have made its way inside your system. If you check the unit and this is not the case, then the problem is potentially much more significant, and will require maintenance.
