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.
This class will feature free equipment calibration. 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.

Many homeowners are considering changing ‘Gas Furnaces’ to ‘Heat Pumps’ to provide residential heating and cooling.
The Training builds upon the ACCA Wrightsoft series and focuses on the Science of correct sizing of Heat pump systems and includes a Wrightoft computer lab portion.
The session builds upon Manual ‘J’ and provides a foundation upon which Manual ‘H’ will be built.
It is recommended that attendees bring their own laptop preloaded with the Wrightsoft Demo software
As homes become tighter and use energy more efficiently, airflow and airflow balance is going to become increasingly important . Comfort and indoor environmental quality are dependent upon proper airflow into each room. The session starts with a classroom discussion covering the basic science and calculations involving airflow balance. Followed by a lab session that allows the material covered in the classroom to be put to practical use in a lab exercise.
Airflow measurements will be made with a flow grid and flow hood, other topics that will be demonstrated focus on the California Title 24 Part 6, approved Airflow measurement and Fan Watt efficacy calculations.
