Heating, Ventilation, & Air Conditioning (HVAC)

Heating, Ventilation, & Air Conditioning (HVAC)

Technical Diploma

When nature’s thermostat rises and falls, heating, ventilation, and air conditioning (HVAC) technicians are there to provide thermal comfort throughout our day and respond when our AC unit or furnace decides to act up. Besides offering temperature control, their work to monitor air quality and provide us with fresh air ensures we can breathe easier.

A Closer Look

HVAC technicians work directly with customers and in all types of residential and commercial environments to ensure that air conditioning and heating equipment are working properly. They have a wide range of duties, such as maintaining, replacing, and installing new units, which often require the use of blueprints and schematics.

HVAC technicians are busy repairing and troubleshooting, but each day offers variety and a different problem to solve. They have strong problem-solving skills and need excellent communication skills to help provide excellent service and ensure customer satisfaction.

What You'll Learn

Mid-State’s Heating, Ventilation, and Air Conditioning program provides the hands-on foundation needed for an entry-level position in the heating, ventilation, air conditioning (HVAC) fields. Graduates will understand the various components of heating, ventilation, air-conditioning, and refrigeration systems, including furnaces, ductwork, boilers, hydronic piping, HRVs (heat recovery ventilators), evaporators, condensers, circuits, and controls.

Students will also explore geothermal, biomass, and solar heating systems. Through hands-on classroom lab activities, students will join various piping types, design and construct ductwork, and install a complete residential HVAC system. They will also learn the electrical skills necessary to read wiring diagrams and troubleshoot mechanical control systems. Graduates are prepared to take the EPA 608 Technician Certification exam for refrigerants.
