While an AC system doesn’t operate silently, it shouldn’t make strange sounds. Anything outside of clicking on or off and soft air movement could indicate a problem that should not be ignored. A noisy air conditioner is a sign that it’s time to call a professional.
At Masters Heating & Cooling, we’re proud to offer comprehensive AC and mini-split services for air conditioners making noise in the Indianapolis area. Whether you’re experiencing banging or hissing, our team is here to provide you with an accurate diagnosis for any strange AC noises. Read on as we discuss common sounds that systems with issues make, along with the steps needed to fix them.
What To Do If Your AC Is Making Noise
If your AC is making noise, don’t delay in scheduling repairs. Sounds like clicking or rattling are all signs that there is an internal issue with your system and, if left unaddressed, could lead to further damage and more serious repairs down the line. Call an HVAC professional if you’re system is making any of these noises.
Banging or Clanking
If your system is making a banging or clanging noise, there’s a good chance that it has a loose or broken part or that there may be something out of balance. The most common area for these issues to occur is in the compressor or blower. To avoid further damage, we recommend shutting down your AC until a professional can arrive for an assessment. They’ll check for issues like broken pistons, disconnected rods, or misaligned fan blades before providing the necessary repairs.
Clicking
A few clicking sounds when you start or shut down your AC isn’t unusual. However, if the clicking is continuous, you may have an issue. Electrical problems like loose wiring can be the root cause, along with other issues like a failing thermostat or defective control board. Inspect your thermostat and replace batteries to troubleshoot. If this doesn’t solve the problem, you’ll need a technician to assess the electrical connections and relays.
Hissing
Hissing is the result of leaks within your AC. While a leaky duct or internal valve leak may not require immediate attention, a refrigerant leak is a serious issue that should be handled quickly. A professional technician is EPA-certified to handle these hazardous refrigerant issues safely and can inspect the levels and pressure of your system to determine the best solution.
Rattling
Rattling can be a frustrating AC issue, as it is constant and disruptive. Usually, it is the result of loose screws and panels that are old or have deteriorated. Other possible causes include debris in the system or a worn-out fan motor or compressor. To eliminate the noise, a technician will tighten any loose components, clear away debris, and look for internal wear that could cause the system to experience a failure.
