* Requirements

* Familiarity with HVAC Systems

Description

This course is designed to help a technician to troubleshoot an HVAC system. Using step-by-step approach, we address both common problems and the ones often overlooked. We start without tools, simply by feeling, hearing and looking. Then we move onto using actual tools.

The attendee will be shown diagrams which help to make sense of instructions pertaining to performance of certain procedures necessary to properly troubleshoot an HVAC system.

We discuss temperature probes, refrigeration gages, an anemometer, an airflow hood, information they provide and steps necessary to achieve an accurate diagnosis of the problem.

We touch on superheat and sub-cooling as well.


Have you gone to fix an AC unit only to get a call back a day or two later with a complaint the unit is still not working?

Do you have an AC unit on your property which seems to have had every part replaced and still not working?

Do you want to advance your knowledge base by acquiring the troubleshooting tools that you will be using again and again saving you time and money?

Logical, step by step troubleshooting method taught by the HVAC instructor with more than 30 years of experience.

The money spent on this webinar will we recouped just in one service call!


"During my over 30 year HVAC teaching career I’ve encountered lots of questions regarding troubleshooting HVAC systems. I realized that many of these questions repeat themselves and I developed a logical, step by step troubleshooting system which I will share with you."

Julio Herrera, Instructor

Introduction to HVAC Troubleshooting and what will be covered. Troubleshooting unit and accessories without tools. Finding a bad dryer and replacing it.

HVAC Troubleshooting Algorithm Part 2 Preview 10:09

Preliminary checks, essential things to look for. Airflow and how much you should have, is your condenser and evaporator ok?

HVAC Troubleshooting Algorithm Part 3 Preview 12:10

Checks on the refrigerant side. What the pressures and temperatures should be. Superheat and subcooling, what are they and how to obtain them.

HVAC Troubleshooting Algorithm Part 4 Preview 10:12

How airflow can affect the pressures and superheat readings. Checking and diagnosing problems with suction line filter dryers. Is the refrigerant low, what low refrigerant will cause and how to find it.

HVAC Troubleshooting Algorithm Part 5 Preview 07:15

Condenser problems, what to look for and how to solve them. Where pressures and temperatures should be checked in a system and why?

HVAC Troubleshooting Algorithm Part 6 Preview 13:05

Electrical side troubleshooting. How to test and where to test, the 220v line side, checking fuses with power on and power off and testing contactors.

HVAC Troubleshooting Algorithm Part 7 Preview 10:25

Testing contactors. Testing capacitors, what is a good and what is a bad capacitor, what will a bad capacitor cause and what to look for.

HVAC Troubleshooting Algorithm Part 8 Preview 08:04

Checking windings in a compressor motor, on both 3 phase and single phase. Finding the run and start windings in a single-phase compressor motor.

HVAC Troubleshooting Algorithm Part 9 Preview 08:56

Checking and finding an open overload. The difference between an open overload and an open winding.

HVAC Troubleshooting Algorithm Part 10 Preview 10:39

Checking the 24 volts side. Using schematic diagram with demonstration what each point is in the schematic and in the actual unit, including where to place your test leads. Transformers, what to look for and how to solve the problems.

HVAC Troubleshooting Algorithm Part 11 Preview 09:19

What switches could keep unit from starting, LP, HP, OPS etc… You will see the schematic showing the circuit and where the switches are located and where the problem could be? Testing the 24v side of the system and the contactor and what to look for in the entire circuit.
