No matter the weather, heating and cooling systems keep homes, offices and schools at the optimal temperature. Students learn how HVACR technicians install, maintain and repair these complex and increasingly high-tech systems in our Heating/Air Conditioning & Refrigeration program. As they explore a career field with an employment growth rate that’s three times the national average, students are introduced to the following skills:

  • Cut and assemble various piping materials, including ACR copper tubing, CSST and PVC pipe
  • Wire series, parallel and series-parallel circuits; install electric disconnects, circuit breakers and fuses
  • Install and service a variety of cooling, heating and refrigeration systems, as well as their components
  • Fabricate air ducts; evaluate ventilation systems’ performance by measuring air velocity, volume, etc.

Instruction begins with job-site safety, tool use, blueprint reading and other fundamentals before moving to advanced tasks like gas furnace maintenance, refrigerant recovery and heat pump installation. Working in a program lab equipped with appliances made by Carrier, Goodman, Honeywell, Trane and other industry-recognized manufacturers, students collaborate to complete projects that mirror on-the-job tasks.

First- and second-year students, for example, wire thermostats, add ductwork to an existing ventilation system and install condensate, gas and refrigerant lines. Third- and fourth-year students, meanwhile, build a sealed HVAC system, troubleshoot an ice machine and install a geothermal unit. Upperclassmen are encouraged to further develop their skills by securing internship or co-op positions with local companies.
