Hands-on Refrigerant Charge Measurement @ SDG&E Energy Innovation Center
Sep 27 @ 8:00 am – 12:00 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 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.

Advanced Blower Door Diagnostics and Air Leakage Identification @ SDG&E Energy Innovation Center
Sep 28 @ 8:00 am – 12:00 pm

Class Overview:

Learn advanced Manometer settings while conducting a Blower Door test. We will cover methods used to identify and prioritize build shell leakage. Students will learn to set up BD, Manometer, hoses and house in order to conduct a total shell leakage. Learn to calculate the Building Airflow Standard (BAS). We will also cover the importance of comparing the BD results with the BAS when recommending air sealing. Participants will practice methods in field guided by instructor.

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.

HVAC System Air Flow and Static Pressure Diagnostics @ SCE Energy Education Center
Jan 19 @ 8:00 am – 12:00 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.
