4 Reasons Your AC Is So Noisy in Buda, TX

Your air conditioner in your Buda, TX home should operate normally with minimal noise. Paying attention to unusual sounds can help catch problems early and reduce energy and repair costs. Here are four common reasons your AC may create excess noise.

1. Dirty Air Filter

A dirty air filter restricts air moving through the system. This may cause whistling noises. You can avoid this by checking your air filter once a month.

2. Worn Electrical Components

Your air conditioner relies on multiple electrical components to operate effectively. The ones that commonly wear include capacitors and the contactor.

The contactor closes the circuit that allows the compressor to run. The capacitor stores a large electric charge to start a cooling cycle.

A worn capacitor may emit a loud buzzing sound. A faulty contactor may sound like teeth chattering and can cause rapid compressor cycling. In either case, shut the system off and call for a repair technician.

3. Refrigerant Leak

Residential air conditioners operate as closed systems, meaning they should remain sealed and not need routine recharging of the refrigerant. However, your system may develop a leak through damage or a faulty compressor. With a bad leak, you may hear a hissing or bubbling sound near the leak location.

You may also notice ice on the system, such as on exposed refrigerant lines or the outside condensing coil. Routine AC maintenance checks for refrigerant leaks before they get to the point of causing problems.

4. Mechanical Malfunction

Mechanical malfunctions like a faulty compressor or fan motor may also generate noise. A bad compressor produces a buzzing or humming noise. A bad fan motor may produce banging or squealing noises.

Unusual noises can cost you in both excessive energy use and operational wear. Call to schedule an AC repair visit from the technicians at Del’s Heating & Air Conditioning for any of these noises.
