Professional Development Hours: PDH, CEU & LU Guide

Professional Development Hours for HVAC Professionals

Professional development hours quantify continuing education requirements for licensed engineers, certified technicians, and accredited professionals in the HVAC industry. Understanding the distinctions between PDH, CEU, and LU systems ensures compliance with state licensing boards, professional certifications, and credential maintenance programs.

Credit System Definitions

Professional Development Hours (PDH)

PDH represents the standard measurement for Professional Engineer continuing education:

Calculation Basis:

1 PDH = 1 contact hour of instruction
60 minutes of actual instruction time
Excludes breaks, meals, administrative time

Structural Engineer (SE) license
NCEES record maintenance
Some specialty engineering certifications

Acceptance Criteria:

Technical content relevant to practice
Qualified instructor or author
Documented learning outcomes
Verifiable attendance or completion

Continuing Education Units (CEU)

CEU provides standardized measurement for non-credit educational programs following IACET standards:

Calculation Basis:

1 CEU = 10 contact hours
0.1 CEU = 1 contact hour
