Gary Phetteplace's experience with ground-source heat pumps (GSHP) dates back to demonstration installations of vertical and horizontal systems performed in the early 1980's at the CRREL facilities in Hanover, NH. He soon after was responsible for the demonstration of some open loop systems in family housing units at Ft. Dix, NJ. His next major demonstration project was at Ft. Polk in the late 1980's where several sets of vertical ground coupled systems (GCHP) were installed and closely monitored along with new air-to-air units for comparison purposes.

Gary Phetteplace also was responsible for projects that instrumented and monitored a hybrid vertical GCHP at Ft. Polk as well as a school for the Navy at Patuxent River Naval Air Station. Gary Phetteplace organized and taught in whole or in part a number of courses in design of GCHP systems for both DoD and ASHRAE. He currently is an instructor in HeatSpring Energy's ( geothermal heat pump curriculum. Gary Phetteplace has twice chaired ASHRAE's Technical Committee TC6.8, Geothermal Energy and he remains active in the committee.
Gary has provided GSHP design review and feasibility analysis services to various public and private entities.
