How Long Can I Expect My Geothermal System to Last?


One of the most reliable and energy-efficient systems we offer our customers is the geothermal HVAC system. A common question we receive is, “How long can I expect my geothermal system to last?” Today, we’ll dive into the life expectancy of residential geothermal HVAC systems, focusing on both the heat pump elements and the underground loops, and offer tips on how to maximize the longevity of your system.

Understanding Geothermal HVAC Systems

Geothermal HVAC systems harness the stable temperatures found underground to heat and cool your home. The system comprises two main components: the heat pump and the underground loop system. The heat pump is located inside your home, while the loop system is buried underground in your yard.

Life Expectancy of the Heat Pump

The heat pump in a geothermal system is a crucial component that transfers heat between your home and the underground loops. Typically, geothermal heat pumps have a life expectancy of about 20 to 25 years. This is significantly longer than traditional air-source heat pumps, which usually last between 12 to 15 years. The extended lifespan of geothermal heat pumps is due to their protected indoor installation, which shields them from the elements and reduces wear and tear.

Life Expectancy of the Underground Loops

The underground loop system, also known as the ground heat exchanger, is designed to last even longer than the heat pump. These loops are made from high-density polyethylene (HDPE) pipes, which are incredibly durable and resistant to corrosion. When properly installed and maintained, the underground loops can last 50 years or more. In fact, many loop systems are expected to outlive the buildings they serve.

Maximizing the Life of Your Geothermal System

To ensure you get the most life from your geothermal system, regular maintenance and proper installation are key. Here are some tips to help you maximize the longevity of your geothermal HVAC system:

Regular Maintenance

Regular maintenance is essential for keeping your geothermal system running efficiently. This includes annual inspections by a qualified HVAC contractor to check for any issues and ensure the system is operating at peak performance. 

Proper Installation

The longevity of your geothermal system starts with proper installation. It’s essential to work with an experienced HVAC contractor, like Schaible’s Plumbing & Heating Inc., who understands the complexities of geothermal systems. Proper installation ensures that the system is correctly sized for your home and that the loops are installed at the appropriate depth and spacing.
