Objective and Function

The primary objective of the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners is to protect the public from unsafe practices and practices which tend to reduce competition or fix prices for services. The Board must also maintain standards of professional competence and service delivery. To meet these objectives, the Board

  • develops standards for professional competency
  • promulgates rules and regulations
  • adjudicates complaints against practitioners and, when necessary, imposes disciplinary sanctions.

The Board issues master plumber, master HVACR and master restricted HVACR licenses. Restricted licenses limit practice to a specialty such as air conditioning.

The Board's statutory authority is in 24 Del. C., Chapter 18.


The Board meets the second Tuesday of each month at 8:30 a.m., except August and December. All meetings are open to the general public and are held in the Cannon Building, 861 Silver Lake Boulevard, in Dover.

To ensure that business (such as a license application) is on the agenda for the Board's consideration at its next meeting, submit all documentation to the Board office no later than 4:30 PM ten full working days before the meeting date.



PROPOSED RULES ON CONTINUING EDUCATION REQUIREMENTS : The Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners will hold a public hearing on its proposed rules to establish continuing education (CE) requirements for license renewal. The Board encourages licensees to participate in the rule-making process by attending the hearing or submitting written comments.

The hearing will take place during the Board’s regularly scheduled meeting on September 9, 2014, 8:30 a.m., at the Cannon Building, 861 Silver Lake Boulevard, Conference Room A, Dover, Delaware.

Under the proposed rules, all licensees who have held a Delaware license for at least two years would be required to complete six hours of Board-approved CE courses during the two years before the license expiration date.  The proposed CE requirement would go into effect starting with the 2016 renewal.
