A highly efficient heat pump delivers all-season comfort for your home in Libertyville, IL. However, if strange noises begin emanating from it, the situation can quickly devolve into a truly uncomfortable situation. Here are four typical sounds that a heat pump makes and what they mean.

1. Hissing or Bubbling

A hissing or bubbling noise signals a potential refrigerant leak. Your system relies on the refrigerant to transfer heat, so any leaks can significantly impact its efficiency. The system may struggle to maintain desired temperatures, leading to higher electricity usage.

Low refrigerant levels can lead to uneven airflow or trapped air in the lines. It’s best to contact a professional with specialized training and necessary equipment.

2. Screeching or Squealing

A squealing or screaming sound is not only annoying — it also indicates a faulty compressor or fan motor bearing. Regular heat pump maintenance can help you identify this problem in time to prevent it from worsening.

3. Clicking or Tapping

When you turn your heat pump on, it typically makes one or two clicks. This familiar sound comes from the compressor switching on and off. However, repeated clicking from the outside unit could signal an electrical issue in your system.

The control board, compressor, relay switch or capacitor in your system might be the cause. Ignoring electrical issues poses risks like damaging your HVAC system or even starting a fire. So, if your system produces continuous clicking noises but doesn’t switch on, have it needs to be checked.

4. Banging or Clanking

Clanking or banging sounds come from loose or detached components in your heat pump. These systems vibrate when they operate; this can loosen screws and other parts over time. If left unchecked, the loose components can damage the expansion valve or other parts of the unit.

Never ignore unusual noises from your heat pump. Have a professional HVAC technician inspect and fix the problem before it escalates. Contact Ireland Heating & Air Conditioning Co. for all your heat pump repairs and maintenance services.
