EPA Core and Type II @ Johnstone Supply/Fresno
Oct 19 all-day

Class Overview:

This class will consist of a 5-6 hour guided study session for the EPA 608 exam, followed by a closed book, on-line certification exam. This certification is required for all raters who wish to perform refrigerant charge verification. The cost of the exam is $50. The 5-6 hour guided study session and study guide are free. If you already own the Mainstream Engineering EPA 608 study guide, you only need to pay the test fee. We will NOT be covering the Type I or Type III materials. We will only be covering the Core materials and the Type II materials. You are free to take whatever parts of the exam you want to, but HERS raters only need to be Type II certified to perform refrigerant charge verification for Title 24 purposes.

Combustion Safety @ Johnstone Supply/Bakersfield
Oct 20 @ 8:00 am – 12:00 pm

Class Overview:

This training will go into depth on how to conduct a Combustion Safety Test (CST) in the Combustion Appliance Zone CAZ under Worst Case Depressurization (WCD).

The following topics are covered:

  • How to prep the CAZ
  • Set up pressure gauges, measure and record baseline pressure and WCD pressures
  • Firing heating appliances and identifying if the appliances will draft within 60 seconds
  • Conducting measured draft and CO Reading at steady state
  • Scenarios if the appliances fail CST
  • Steady state and/or ambient CO problems
  • Identifying potential venting problems
  • Recommendation based on Combustion air venting tables
HVAC System Air Flow and Static Pressure Diagnostics @ Johnstone Supply/Bakersfield
Oct 20 @ 1:00 pm – 5:00 pm

Class Overview:

This four hour session covers the science and application of airflow principles to the efficient operation of HVAC equipment. Many of the residential systems in California suffer from the inefficiencies caused by high static pressure. Included in this training is a hands-on portion designed to compare various filters, fittings and layout issues that cause high static pressures.

Equipment Calibration Class @ SCE Energy Education Center
Nov 15 @ 5:00 pm – 8:00 pm

Class Overview:

Properly maintained and calibrated equipment insures measurement accuracy in the field and improves equipment performance and longevity. Attendees will have the opportunity to check HVAC, blower door and duct tester equipment calibrations. Instructor Gary Wollin will show attendees how to apply the principles for calibrating digital thermometers, refrigerant gauges (P/T) and pipe clamps used for checking pipe temperatures for both the liquid and suction lines. Attendees will be shown the field test procedure for digital manometers and be able to check personal manometers against newly calibrated manometers. Duct blaster inspections for proper airflow will also take place. There will be a demonstration on how to maintain duct blaster equipment including cleaning and checking for damage, and misalignment of the fan and plugged orifices.

Hands-on Refrigerant Charge Measurement @ SCE Energy Education Center, Irwindale
Jan 19 @ 1:00 pm – 5:00 pm

Class Overview: A residential split system air conditioner undergoes its final assembly at the time of installation. An important factor is the amount of refrigerant in the system (commonly referred to as proper charging). Air conditioner energy efficiency suffers if the refrigerant charge is either too low or too high. This training is designed to assist HERS Raters and HVAC technicians to properly perform a Refrigerant Charge verification. This is a Hands-on class with operational equipment. Please feel free to bring your verification equipment.
