Geothermal.contractors

E-D-S Lighting and Underground Utilities Inc. is a Greenville, South Carolina-based geothermal and utility contractor providing ground-source heat pump installation alongside directional drilling, site lighting, underground utility placement, excavation, trenching, and home generator services. Founded in 1995 and family-owned, E-D-S installs three closed-loop ground configurations: horizontal loops for properties with ample acreage, vertical bore loops for space-constrained sites, and pond/lake loop systems where suitable water bodies are present. An IGSHPA member and listed WaterFurnace dealer, the company pairs demonstrated geothermal loop expertise with conventional underground-utility work, and also serves as an authorized Kohler generator dealer for residential and commercial backup power. E-D-S serves clients across South Carolina, North Carolina, and Georgia from its Greenville base, handling both single-family geothermal retrofits and larger commercial loop-field projects.
