HERBERT J. HOELTER VOCATIONAL TRAINING CENTER HVAC CURRICULUM

HVAC (heating, ventilation, and air-conditioning) technicians install and maintain the HVAC systems found in industrial, business and residential buildings.

These systems handle all aspects of climate control, including heating, air quality, temperature and humidity control in homes, industrial plants, office
buildings, schools and hospitals. HVAC technicians install, repair and maintain these systems, which consist of complex mechanical, electrical and electronic components such as motors, compressors, pumps, fans, thermostats, and switches.

HVAC presents the working principles of heating, ventilation and air conditioning the most effective way: using the same industrial-strength components used in industry. All trainers include competency based curriculum with emphasis on operating theory, installation, maintenance, and troubleshooting.

Program Objectives

Upon successful completion of this course, students will be able to:

  • apply for and acquire an entry-level position in the HVAC field;
  • exhibit confidence servicing and installing HVAC systems;
  • achieve a broad knowledge of all applications of HVAC, both practical and scientific.

Program Course Sequence:

HVAC Safety, Tools & Methods: Explores the tools used in the HVACR trade and how to accomplish basic tasks. The course highlights construction of fittings made of sheet metal and glass duct board for air duct systems. Safe use of tools and safe procedures for soldering and brazing is emphasized.

Fundamentals of Refrigeration: Introduces the compression refrigeration cycle, common refrigerants and their applications, and the theory of heat transfer as related to the refrigeration process. Teaches how to evaluate system performance and how to use tools and equipment for service and installation procedures such as charging, evacuating, and leak detection.

Heating Systems:  Studies the construction and operation of gas fired, oil fired, and electric forced air heating equipment (and other related systems as time allows); introduces procedures for installing, testing, and adjusting and maintaining heating equipment.

Basic HVAC Electricity:  Discusses A.C. and D.C. circuit fundamentals. Discusses basic wiring and construction principles, commercial and industrial wiring, residential wiring, the purpose and use of the National Electrical Code, and the How’s and Why’s of basic wiring and construction.

Comfort Cooling Systems:  Applies the theory and principles of refrigeration to comfort cooling and explains the use of electric heat pumps in residential and light commercial applications. Describes the regulations and procedures that apply to refrigerant recovery, recycling, and reclaiming and offers hands-on laboratory work in recovery and troubleshooting.

Residential Load Calculations & Air Distribution:  Introduces methods to calculate heat losses and gains (loads) for residential and commercial applications using the Air Conditioning Contractors of America (ACCA) Manual J and Manual D procedures and computer software programs. Students learn to select the proper heating and cooling equipment for maximum comfort and energy efficiency. The course also introduces air side equipment, components from manufacturers’ specifications and various instruments used to test and balance air distribution systems.

Refrigerant Recovery Certification – ESCO Certification:  Reviews Environmental Protection Agency (EPA) regulations and procedures to properly handle refrigerants and prepares students for the EPA Technician Examination. Persons who maintain, service, repair or dispose of appliances that contain regulated refrigerants must be certified in proper refrigerant handling techniques.

Skills for Success:

Detailed-oriented, dependability, self-control, ability to follow safety rules, ability to follow directions, cooperation, integrity, persistence, manual dexterity, mechanical aptitude, mathematical aptitude, ability to stand for long periods of time and ability to lift 35 pounds.

Textbook:

Fundamentals of HVACR, 3rd edition with access code, by Stanfield & Skaves

Career Opportunities:

Entry Level HVAC Helper/Apprentice. Students can continue their education and obtain additional certificates and/or pursue an Associate of Applied Science degree in Heating, Ventilation & Air Conditioning (HVAC) and Energy Technology.  Some companies prefer or require a degree for more senior positions.  Criminal background checks and random drug testing are required for employment.
