Our Process
Site Survey
We evaluate your property for geothermal feasibility — lot size, soil composition, groundwater depth, and existing HVAC infrastructure.
Loop Design
We design the ground loop system — horizontal trenches, vertical boreholes, or pond loop — sized to your home's heating and cooling load with Manual J calculations.
Loop Installation
Our excavation team installs the ground loop with directional drilling or trenching equipment. We restore your property to its original condition. Loop installation takes 2-5 days.
Heat Pump & Commissioning
We install the geothermal heat pump inside (mechanical room), connect to ground loop, and verify peak efficiency. You'll enjoy silent, efficient comfort for decades.
