Tips to Solve Loud Noises in Your Air Conditioner: Expert Advice for Columbus, GA Residents

Air conditioners are complex machines, and various parts can cause strange noises. Knowing what these noises mean can help you figure out what's wrong. Here are some common reasons for loud noises in AC units:

Banging or Clanking Noises

A banging or clanking noise often points to a problem with the compressor, which is the core of your AC system. The constant shaking and pressure can make internal parts like pistons connecting rods or support springs loose or move out of place. This leads to a loud metallic noise when they hit the outside of the compressor.

Hissing or Whistling Sounds

If you hear hissing or whistling noises, they might indicate a refrigerant leak in the system. Refrigerant acts as the vital fluid in your AC setup, and when it escapes through gaps or holes in the pipes or parts, it makes a high-pitched noise because of the pressure difference.

Buzzing or Humming Sounds

A constant buzz or hum could mean problems in the outdoor cooling unit or the indoor air mover. This might happen due to old bearings, loose contact issues, or a broken contact relay switch.

Noises that happen now and then when cooling starts or stops are nothing to worry about. But if you hear sounds that don't stop or keep coming back, it could mean parts are loose, something's blocking the fan blades in the condenser, or the thermostat isn't working right.

To start fixing the problem, you must figure out what kind of noise your AC is making.

Tips to Fix It Yourself

Some AC problems need a pro to fix them. But there are a few easy things you can try first to solve the issue or at least get a better idea of what's causing it:

• Inspect the Unit: Look at your AC's indoor and outdoor parts. Check for loose pieces, screws, or junk that might make noise or shake.
• Check the Fan Blades: Make sure the fan blades in both the outdoor unit and inside are tight and not bent or broken. Damaged blades can make all sorts of noises.
• Clean the Coils and Air Filters: Dirty coils or clogged filters can limit airflow. This forces your system to work harder and might cause noise problems. Use a soft brush to clean the coils and install new air filters when needed.
• Listen for the Source: Use a screwdriver or something similar to make the sound louder. Put the metal end on different parts while holding the handle to your ear. This can help you find where the noise is coming from.

When fixing your AC, be careful not to try repairs you're not qualified for. If you don't know what you're doing, messaging with AC parts can cause more problems or even be dangerous.

When to Call a Professional

While you can handle some small problems yourself, in some instances it's best to get help from an expert:

• Persistent Noises: If noises continue after you've tried to fix them, you should get help from a professional. Putting off ongoing problems can result in more serious and expensive repairs later.
• Decreased Cooling Efficiency: If your air conditioner isn't cooling as well as it used to, along with noises, you need a pro to take a look.
• Refrigerant Leaks: Hissing or whistling sounds often mean you have a refrigerant leak. This can be dangerous, so a licensed HVAC tech needs to handle it.
• Compressor Issues: Loud banging or clanking noises from the compressor can point to a big problem that might need expert attention.
