Replacing Your DX Geothermal System: A Comprehensive Guide

| August 16, 2023

Are you considering replacing your existing DX geothermal system? Upgrading to a new and improved system can enhance energy efficiency, lower operating costs, and provide greater comfort for your home. To ensure a smooth transition and make the most informed decision, we’ve put together this comprehensive guide on replacing your DX geothermal system. A Waterless® Geothermal can replace many of the more popular, older DX geo brands that were installed like Earthlinked, Advanced Geothermal, US Power, and Great Air Comfort System Units. Let’s dive in!


1. Be aware of contractor with no direct exchange geothermal experience.

Don’t be alarmed if a contractor doesn’t have direct exchange geothermal experience. It is not uncommon for a contractor to suggest replacing your DX geothermal unit if they’re not familiar with the technology. Many contractors will suggest replacing a perfectly good system that may need a minor repair with a new type system that they are more familiar with. Contractors that are unfamiliar with your direct exchange geothermal technology will often suggest replacing your geothermal system with a less efficient air source heat pump. The fact is, that the most efficient air source heat pump on the market today is less efficient than your geothermal system. If you do need a new system, a new air source heat pump may appear to be a less expensive option. However, after you deduct the 30%-40% federal tax credit off of a new geothermal system it can often be less expensive to reuse your existing loop field + install a new DX unit.
