How can I renew my certification?

Continuing education is required every three years for certification renewal. 

During the 3-year period, 8 points must be accumulated to renew your certification and an IGSHPA Continuing Education Form must be submitted. The points can be accumulated three ways:

• Employment
  • You may accumulate up to 4 points by remaining continually employed for 3 years in the combined geothermal heat pump and heating, ventilation, and air-conditioning field.
  • Total points = (number of years x 1.33)
• Membership in an approved organization
  • Approved organizations include IGSHPA, the National Ground Water Association (NGWA), the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), and similar organizations
  • 1 point = each year of membership
  •  Membership in more than one organization will apply toward accumulation of multiple points per year.
• Education
  • Points can be accumulated by participating in continuing education or professional activities in the combined geothermal heat pump or HVAC field.
  • 2 points can be accumulated for each 20 contact hours in seminars or training.
    • Total contact hours x 0.1 = CEU credit points 
  • 2 points can also be accumulated for each college credit hour, if that applies.

IGSHPA memberships & certification can be purchased for 1 or 3 years at a time. IGSHPA members receive a discount on certification renewal (your membership term must match certification renewal term). An annual IGSHPA individual membership is $125/year. Member certification renewal is $75/year, while non-member certification renewal is $225/year.
