Accredited GeoExchange Drillers (AGD)

Garen N. Ewbank, works with a group of independent drilling contractors that are available to drill your ground heat exchanger or "partner" with other contractors to install the earth side of the systems. Drillers are licensed in their respective areas and accredited by the International Ground Source Heat Pump association as Installers. Please contact Garen to discuss this opportunity.


Ewbank recommends that the owner use a master drilling contract with the driller. Each project is then a job "or site specific" drilling contract attached to the master drilling contact as an addendum. Each driller brings knowledge and best practices to the ground heat exchanger installation that is not generally available to the owners. All drillers have the experience and training to draw upon to improve their performance installing ground source heat exchangers and solve site specific drilling issues for the owner.

Each driller listed is experienced and trained in conducting (by direct measurement) thermal conductivity, deep earth temperature, thermal diffusivity (from drill logs) and HDPE pressure testing.

Recommeded Drillers are below:
