The Causes of 5 Common AC Noises in Charleston, SC

When your air conditioner in Charleston, SC becomes faulty, it displays signs that show all is not well. If you hear any of these AC noises coming from your HVAC system, it’s time to schedule a repair.

1. A Clogged Air Filter: Whistling

An air filter prevents impurities from contaminating your AC’s components by catching them before they enter the system. Filtering the air also helps to protect your family from irritations associated with poor indoor air quality, such as sneezing, headaches, runny nose and watery eyes.

These impurities clog the filter over time if you don’t replace or clean the filter. You may hear a whistling sound as the system draws air through the blocked filter.

2. Refrigerant Leaks: Hissing

You may detect a hissing sound when the refrigerant escapes through tiny punctures along the refrigerant lines. When air enters the refrigerant lines through these damaged sections, gurgling or bubbling noises occur as the refrigerant mixes with the air bubbles.

3. Loose Components: Banging

Loose internal components can produce banging sounds as they hit other parts, while loose cover panels may produce rattling noises. Schedule repair services to fix or replace the worn-out components.

4. A Faulty Compressor: Vibrating

You may hear a vibrating sound every time a faulty compressor starts. The malfunctioning compressor consumes too much energy; hence, you should have the issue addressed by professionals as soon as possible.

5. Electrical Issues: Buzzing

When your system’s electric connections have problems, you may hear a buzzing noise. You should never attempt to repair electrical issues by yourself because you may get electrocuted. Instead, let a professional diagnose the underlying problem and fix it.

Don’t ignore any weird sounds that your air conditioner produces. Call our team at M & B Heating and Air for professional air conditioning services.
