The course starts out with the evaporator, introducing its  functions, some new terminology, and methods for quantifying its performance, such as superheat and Delta T. Next, students will learn about the condenser functions and its quantifiers, sub cooling and condenser split,  and what those values translate to in the system. Some maintenance techniques are explored as well, such as  coil cleaning and diagnosing mineral deposits.

Prerequisite: HVAC-102

In this course, students will learn about a fundamental component of an HVAC system, the compressor.  Students will discover the many types of compressors, with a focus on reciprocating, scroll, hermetic and  semi-hermetic. Additionally, they will learn how to calculate compression ratios and their significance on a  system, the importance of lubrication, and maintenance methods.

Prerequisite: HVAC-103 

The Metering Device course explores the multitude of regulating valves in an HVAC system. Students will  learn to identify valve types and discover how they are fitted to a pipe, as well as, differences in external and  internal pressure equalization. Additionally, they will discover TEV bulbs and their roles in regulating  superheat within the system, along with proper placement and methods for installation. Finally, students will  learn the unique model codes for some common manufactures and the functions of several different kinds of metering devices.

Prerequisite: HVAC-104 

The Leak Check and Evacuation course presents three methods for checking a system for leaks and the  processesto follow. Given the advantages and disadvantages of each method,students will follow through a  step-by-step illustration of each. As students are guided through the process, they will be given tips and  safety information by subject matter experts. After leak checks are complete, students will learn about the  Environmental Protection Agency’s regulations regarding leak repairs. Finally, students will discover evacuation methods and be introduced to the vacuum pump as well asthe accompanying equipment that  can help make an evacuation more accurate and efficient.

Prerequisite: HVAC-105 

This course is an overview of how heat pumps work and what makes them different from air conditioning.  Students will gain an understanding of basic components in the operation of heat pumps and how the  reversing valve enables a heat pump to function as a cooling as well as a heating device. Students will learn  how the fixed bore piston metering device works and the advantage of having a thermostatic expansion  valve (TEV) in a piston-type system.

Prerequisite: HVAC-106 

In this course, students will learn the basic components of a gas furnace. Topics will include the pressure  switch, exhaust vent, flame sensor, hotsurface igniter, and transformer. This course can be completed as  a stand alone or as part of HVAC-321 when learning how to troubleshoot.

Prerequisite: HVAC-107 

This course is an introduction to motors used in residential and commercial settings. The course will cover  shaded pole motors,split phase motors, and three phase motors. It will also include a section on the popular  permanent split capacitor motor or PSC.

Prerequisite: HVAC-108 

This course is a culmination of everything students have learned about air conditioning systems. Some new  terminology will be introduced that will help simplify the organized methods of troubleshooting that were  taught. These methods will equip students with the toolsto methodically and accurately diagnose a system.  Students will first review the characterizations of a normalsystem, which will enable them to recognize non normal indications and correlate those indicationsto a faulty system component. After going through all the   faulty component characteristics, students will practice everything they have learned through in depth scenarios.

Prerequisite: HVAC-109 

In the Meters, Circuits, Loads and Switches course, students will learn how to use four of the most common  meters in HVAC today: the voltmeter, ohmmeter, ammeter, and multimeter. They will discover why safety  controls are wired in series, and why most loads are wired in parallel as well as how to measure and calculate  volts, ohms, and amperage and how to use these values to troubleshoot a system.

Prerequisite: HVAC-201 

In the Symbols and Wiring course, students will  translate everything they have learned about HVAC into symbols on a diagram. From relays and contactors,  to safety switches and loads, students will understand the reasoning behind each symbolic representation.  After students have mastered symbols, they will move on to wiring diagrams and learn the different formats  as well as their advantages in the field. Students will learn to transpose real life systems into actual working  diagrams.
