About our Plumbing Certificate

The Heating, Air Conditioning, Refrigeration & Plumbing programs prepare students to install, repair and maintain refrigeration, heating and air conditioning equipment. Students learn about the components and construction of HVACR systems, temperature control and electronics, and how to read blueprints. This program incorporates a hands-on practical approach through work in the lab on HVAC equipment. Graduates enter their field with skills and knowledge in basic electricity, heating and refrigeration systems and air conditioning systems, as well as the skills and competencies for journeyman plumbing.

Special attention will be given to the integration of green technologies. Advanced courses develop more sophisticated design and application skills such as estimating thermal loads, hydronic piping design and controls for more complex circuits including digital. Heating, ventilation, air conditioning and refrigeration (HVAC/ HVACR) technicians can work in private homes, commercial offices, industrial complexes or any other type of building.

The Heating, Air Conditioning, Refrigeration & Plumbing department offers an Associate in Applied Science degree with two options: Heating, Air Conditioning & Refrigeration, and Heating & Plumbing. The program also offers individual certificates in Plumbing, Heating, and Refrigeration & Air Conditioning. The program is designed to prepare students for entry-level employment in the HVAC/Plumbing fields.
