NATE Certified
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.
Class Overview:
Day 3 – Building Energy Science III CLASSROOM: Discuss ‘Refrigerant Charge’ and ‘Equipment Calibration’. HANDS ON*: Combine the Airflow techniques with Refrigerant charge procedures, Multiple opportunities to practice on various pieces of equipment.
Class Overview:
Day 5- Building Envelope II CLASSROOM: Discuss ‘Thermal Bypass and Quality Insulation Installation’, ‘Thermal Imaging’. HANDS ON*: Inspect a wall section, working some of the areas discussed, Use an IR camera and review the results, using a hot wall for the training.
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.
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.
