What is a Refrigeration, Air Conditioning, Heating and Gas Technology Degree?

Students who pursue training in this technology learn how to install, maintain, and repair refrigeration, air conditioning, and heating and gas systems. In short, they learn how to help keep us comfortable and healthy.

Heating and air conditioning systems control the temperature, humidity, and overall air quality in homes, office buildings, schools, hospitals, factories, stores, and other facilities. By providing a climate controlled environment, the refrigeration systems that HVAC technicians install make it possible to store and transport food, medicine, and other perishable items.

Program Options

Apprenticeship in Refrigeration, Air Conditioning, Heating and Gas Technology – Three to Five Year Duration
A refrigeration, air conditioning, heating and gas technology apprenticeship is the most common education path. The majority of apprenticeships are provided or sponsored by local unions and their affiliates, as well as by non-union contractors. The United Association Union of Plumbers, Fitters, Welders, and Heating, Ventilation, Air Conditioning (HVAC), and Refrigeration Service Techs, for example, regularly offers apprenticeships.

Diploma / Certificate in Refrigeration, Air Conditioning, Heating and Gas Technology – Six Month to Two Year Duration
Associate Degree in Refrigeration, Air Conditioning, Heating and Gas Technology – One to Two Year Duration
These programs are offered by technical and vocational schools. Students should choose a curriculum that is made up of in-school hours followed by an apprenticeship.

Here are the common learning outcomes of both school programs and apprenticeships:

• Basic concepts for reading blueprints and drawings used in the construction, industrial, and maintenance fields
• Fundamentals of refrigeration
• Identification and use of refrigeration tools and materials
• Installation and service of the components of different types of air conditioning and refrigeration systems
• Basic ventilation requirements
• Fundamentals of air distribution and cleaning systems
• Servicing refrigerant control systems and air conditioning control systems
• Working with advanced circuitry systems and innovative instruments
• Choosing the right piping materials for different applications
• Testing pipe or tubing joints or connections for leaks
• Testing electrical circuits or components for continuity
• Repairing or replacing defective equipment
• Improving refrigeration, air conditioning, and heating and gas system performance by changing filters, cleaning ducts, or refilling refrigerants
• Installing, connecting, and adjusting thermostats, humidistats, or timers
• Connecting equipment to fuel, water, or refrigerant sources
• Adjusting system controls to balance system
• Assembling, positioning, and mounting refrigeration, air conditioning, and heating and gas equipment
• Cutting or drilling holes in structures to accommodate system installation
• Lay out, design, and install low voltage electrical wiring
• Record and report time, materials, faults, deficiencies, and other occurrences on work orders
• Job Site Safety
