Should Heat Pumps Make Noise in Metairie, LA?

When you notice sounds coming from your Metairie, LA heat pump, it’s normal to wonder if something is wrong. Here, you can learn more about some of the normal sounds heat pumps make and other noises that indicate trouble.

Some Noises Are Normal

When heat pumps turn on, it’s normal for them to sound like the entire system is shaking for a few seconds as different components activate. Likewise, when shutting down, they generally make rather intense clicking and tapping sounds.

When pumps go into heating or defrosting mode during cold weather, you’ll likely hear powerful swooshing noises. Thankfully, these things are only a cause for alarm if they last for an extended period of time.

Buzzing or Banging Noises

Any buzzing noises are generally reliable indicators that something is wrong. Most commonly, these sounds signal that your heat pump has a dirty or malfunctioning solenoid coil or contactor.

Banging noises are a common hint that one of your pump’s fan blades is loose and is repeatedly striking some other component. In most cases, basic maintenance should be enough to handle these issues, though they may occasionally call for more extensive repairs.

Gurgling Sounds

If you hear gurgling sounds from your heat pump, this may indicate you have a refrigerant-related issue on your hands. For example, there may be air bubbles trapped in your refrigerant lines. Any such issue requires the intervention of trained HVAC technicians, as refrigerant is a dangerous substance that poses serious health risks if mishandled.

Being able to tell the difference between a normal sound and a noise pointing to a potentially catastrophic problem is essential for keeping your heat pump in good shape. If you’re concerned about any of the sounds your heat pump makes, call Vallee Air Conditioning and Heating to inquire about our HVAC services.
