Geothermal Technicians
Geothermal Technicians install, operate, and repair systems that turn underground heat into clean energy for buildings and power plants. They read blueprints, calculate how much heating and cooling a property needs, choose the right equipment, and design underground pipe “loop” systems that match the site’s soil, water, and climate. On the job, they run tests on pipes and pumps, weld high-density polyethylene (HDPE) piping, dig and backfill trenches with excavators and trenchers, and use gauges, sensors, and computer controls to monitor power plant performance and fix electrical or mechanical problems before they cause downtime.
