HVAC Maintenance Courses

HEA101 - Electric Furnace Maintenance

This course develops skills in servicing electric furnaces. Students will learn electric heating principles; how to interpret the schematic wiring diagram; how to trace the sequence of operation; and how to test and evaluate the heating elements, fusible links, limit switches, sequencer, and more. Also, the students will learn how to make repairs in no heat situations, and more importantly, how to make those repairs in safe, efficient and productive manners.

HEA102 - Gas Furnace Maintenance

This course develops skills in servicing gas furnaces. The students will learn to recognize the components, interpret the schematic wiring diagram; trace the sequence of operation; replace defective parts; and adjust the furnace for optimum efficiency. Also, the students will learn to make repairs in no heat situations, clean the furnace, check for gas leaks, check for carbon monoxide leaks and verify that a furnace is safe to operate.

HEA103 - EPA Technician Certification

The primary objective of this course is to prepare students for the EPA Technician Certification exam. It does not require a highly skilled service technician to pass the exam, but some background and experience will be helpful. The students will learn the potential of releasing CFC's and HCFC's into the environment, and information that will encourage them to comply with the Refrigerant Recycling Rule, which is section 608 of the Clean Air Act 1990, as amended CAA.

HEA104 - Air Conditioning Maintenance

This course develops skills in servicing air conditioners. Students will learn how to diagnose the electrical system, the refrigeration system, and the mechanical devices. Specifically, they will develop skills in recovery and evacuation, leak testing, troubleshooting the compressor for mechanical or electrical problems, charging and/or recharging the system, adjusting the unit for optimum efficiency, and making repairs in safe, efficient and productive manners.

HEA105 - Heat Pump Maintenance

This course studies the basic approach to servicing heat pumps. The students will learn principles of a reverse-cycle heat pump; identify and test the components; determine if the unit is heating or cooling by measuring line temperatures; adjust auxiliary heat; and various techniques that will improve the efficiency of a unit. In addition, the students will gain exposure to causes of failures, preventive maintenance techniques, safety information, tools, testing equipment, and most importantly, how to make all repairs in safe, efficient, and productive manners.
