HVAC/R Service Practices Lab

Catalog description

This is a hands-on driven course, a continuation of HVAC/R Service Practices, and offers experience with residential split heat pumps systems, packaged heat pump systems, air conditioners, gas furnaces, and evaporative coolers. Students will undergo learning the process of understanding the design, installation, and the start-up of heating and cooling systems, the effects that superheat and subcooling contribute to proper servicing and testing of equipment. Various components of the mechanical system are further explained and evaluated. Students are tasked with building schematics for air conditioning/heating systems and wiring the same systems having only the components of the system as reference. A further study of mechanical and electrical troubleshooting turns more hands-on in this class as students see the equipment come to life by their hands. Gas piping, sizing, and installation is studied as it applies to furnace operation. An understanding of the laws and regulations required for refrigerants by the EPA, and the opportunity to qualify for EPA section 608 certification is provided during this course. Gas piping, sizing, valves, and installation are studied as it applies to furnace operation.
