**GEOTHERMAL:** AHR was home to the latest in geothermal innovation, including WaterFurnace’s TruClimate 900.

Geothermal technology was a major highlight at the 2026 AHR Expo. Manufacturers showcased new systems designed to improve efficiency, simplify installation, and expand geothermal’s practicality across more applications.

Climate Control Group’s Dan Ellis discusses the commercial and residential geothermal market and how tax incentives (or lack thereof) have affected its adoption, new opportunities for geothermal installation and application, and solutions contractors can employ to offset geothermal cost.
