Minnesota Geothermal Heat Pump Association

BECOME A MASTER GEOTHERMAL INSTALLER

Minnesota has no state licensing requirements for geothermal installation. The MNGHPA Master Geothermal Installer (MGI) designation fills that gap — giving qualified contractors a way to demonstrate their expertise, and giving consumers a reliable way to find them.

Two Designations

MGI — System Geothermal System Designation

Covers the full geothermal heat pump system: design, sizing, equipment selection, and installation of indoor components. Demonstrates mastery of system-level geothermal work.

MGI — Loop Field Ground Loop Designation

Covers ground loop design and installation: vertical boreholes, horizontal loops, pond loops, looping, and grouting. Contractors may hold one or both designations.

How to Earn the MGI Designation

The following requirements apply to both designations. Contractors who hold the MGI designation have met all four criteria and passed a rigorous exam.

Meet the experience requirement

Applicants must document a minimum number of completed geothermal installations appropriate to the designation sought.

(See the MGI application below for specific requirements.)

Complete required training

Formal training through IGSHPA or an approved equivalent program is required before applying to sit for the exam.
(See the MGI application below for specific requirements.)

Pass the MGI exam

A rigorous written exam administered by MNGHPA. Covers system design, installation standards, and Minnesota-specific regulatory requirements. Applicants must pass before receiving the designation.

Commit to ongoing education

MGI holders must maintain continuing education and uphold the MNGHPA Code of Ethics to retain their designation. Renewal requirements ensure credentials remain current.
