About
O'Rourke Groundwater Developing, LLC has served Northern New York since July 1989, providing geothermal heating and cooling installation and well drilling services across Jefferson, St. Lawrence, Lewis, Franklin, Oswego, Herkimer, and Oneida Counties. Based in Adams, the company installs both horizontal loop fields for sites with adequate yard space and vertical bore fields for properties where horizontal installation is not practical. Loop fields use HDPE plastic pipe fused and filled with propylene glycol antifreeze solution and pressure tested before commissioning. The three-step installation process covers property assessment and system sizing, loop field installation, and heat pump connection to the home's heating system, power supply, and thermostat. Additional services include water well drilling, hydro-flushing, pump testing up to 350 GPM, submersible pump installation, and dewatering wells. O'Rourke holds NYSERDA Certified GSHP status and maintains IGSHPA membership. Free estimates available at (315) 232-2110.
