Accredited Installer (AI)

Learning to install Ground-Source Heat Pump (GSHP) systems will keep you competitive in a market forced to deal with rising energy costs and resource depletion. Installer accreditation enables you to open new markets and offers customers a low-maintenance, economical, and environmentally friendly alternative for their space conditioning needs. With more than 35 years of experience teaching these workshops, accrediting thousands of installers, and developing the industry standards, IGSHPA has pioneered training in GSHP installation.

Information gathered from the workshops can help utility representatives serve as a source of information regarding money-saving concepts.
