HVAC tech looking at heat pump outdoor unit - Why Is My Geothermal Heating System Making Strange Noises?

If your geothermal heating system is making strange noises, it’s important to address the issue as soon as possible to prevent further damage and costly repairs. There are several possible causes for loud noises in your heating system, including air bubbles, loose parts, a faulty motor, and more. Read more about the most common issues below.  

3 Common Causes for Loud Noises in Your Geothermal Heating System 

  1. Air in the system: Air bubbles trapped in the heat pump or pipes can cause a range of noises, including gurgling, hissing, banging and bubbling sounds. 
  2. Faulty blower motor: The blower motor is responsible for circulating air throughout the system. If it’s not functioning properly, it can cause loud banging or humming noises. 
  3. Clogged air filter: A dirty or clogged air filter can restrict airflow and cause your system to work harder, leading to increased noise levels and reduced efficiency. 

If you’re experiencing any of these issues, it’s best to contact a licensed HVAC technician to assess and repair the problem.
