When an air conditioner makes extremely loud or unusual sounds, it needs special attention. Unfamiliar AC noises let you know when the system is malfunctioning before the issue escalates or becomes too costly to repair. Here’s a list of a few AC noises that you shouldn’t ignore in your Punta Gorda, FL, home.

Banging

Banging noises indicate a loose component in your air conditioner, like a bolt or nut. It might also mean that the compressor is faulty. A clanking sound may mean that a bigger component is loose, like the indoor blower or outdoor fan, which might need re-balancing or replacing.

Gurgling

An air conditioning unit low on refrigerant is likely to produce a bubbling noise. Low refrigerant levels cause poor performance, making the AC system take longer than usual to cool your home. Schedule a service appointment to fix the leak and refill the refrigerant for optimal performance.

Buzzing

A buzzing noise from the outside unit may indicate loose parts, dirt and debris or dirty condenser coils. Refrigerant leaks, clogged air filters and malfunctioning blowers could also cause a buzzing noise. Hire an AC repair expert to check the source of the buzzing noise and provide a lasting solution.

Squealing

When your AC compressor has high pressure levels, it’s likely to produce loud squealing noises. It could also mean that the belt is faulty, making it face friction and preventing it from moving fast. A professional HVAC service technician will check your AC system and clean or replace the compressor to fix the issue.

Whistling

Is your air conditioner sounding like a whistle? While it’s not as bad as other AC noises, it’s a sign of an underlying problem. Possible reasons include a leaky duct that requires sealing or an obstruction of airflow that you can solve by cleaning or changing air filters.
