Air conditioning provides a sweet escape from the summer heat, especially in places like southwest Missouri where the average temperatures become unbearable. Months of hot, humid weather take their toll on your cooling systems. Fortunately, listening to your AC system can help you identify a problem. Here are three noises that indicate a need for professional repair. 

What Air Conditioning Sounds Should Concern You?

1. Hums 

All units make some level of noise when they operate. The fan in the exterior unit often creates a constant, loud whoosh noise. But deep humming from that outside unit signals significant problems. A failing motor or capacitor are two of the most common issues that humming indicates. But the noise may also occur from loose parts. Finally, electrical and refrigerant issues may be culprits. 

2. Bangs

Light, consistent bangs, in some situations, are from loose screws. And they’re quickly fixed. However, the heavy bangs can come from a more substantial component, like the motor. In either situation, it's essential to get the root of the problem fixed before more damage occurs. 

3. Clicks

Most cooling units make a faint click when turning on and off, which doesn't warrant attention. However, when clicks become repetitive, there's an issue. These constant sounds occur in many different situations, which makes professionals’ troubleshooting more complicated. If the clicks appear to come from the compressor, the relay switch may be the cause. Poor electrical connections and thermostat malfunctions are also possible sources. And don’t be fooled by an infrequent but repetitive click. Because there is still an air conditioning problem. Clicks every few seconds can indicate faulty control boards or fan motors.
