3 Heat Pump Noises You Can’t Ignore in Lebanon, TN

April 26, 2022

The heat pump in your house is likely to produce some sound when it is running optimally. But it can get frustrating when these noises increase or become a bother. Here are three common heat pump noises you can’t ignore in Lebanon, TN.

Banging Metal Sounds

The fan is the most common part of the heat pump that is likely to produce sound since it is moving around throughout the working life of the pump. When there is a loose part of the pump surrounding the fan, it will strike the fan blades and produce a banging metal sound.

When this happens, it is important to consult a professional HVAC company to assess your heat pump. Continued use of the pump when it is producing banging metal sounds will cause further damage to other parts of the heat pump.

Rattling Noises and Vibrations

Another common type of sound that can come from your heat pump is the rattling noise or vibration. This type of sound is hard to ignore since it is very irritating to the ear and can get louder if it remains unresolved. It usually comes from a loose cover panel.

Loud Grinding or Gurgling Noise

These are distinct heat pump noises that you shouldn’t ignore because they’re a warning sign of a damaged pump. Dirty motor bearings are a common cause of the grinding noises. When your heat pump produces a gurgling sound, it means that the refrigerant needs a refill.

If you hear any of the above sounds, it’s important to turn off the heat pump and consult a certified expert to assess your system. Continued use will lead to damage to other parts of the system.
