Class Schedule
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.
This 1/2 day class covers Manual S, Sizing of Residential Equipment based on Manual S and the California title 24 Part 6 parameters. Material includes: Reference App JA-II, Various Manufacture Equipment Data sheets, a PowerPoint with a step-by-step work through, and a Wrightsoft Computer element, Other ACCA Approved Software is being brought into the training at this time.
The course covers Basic concepts of duct design. Covers air flow dynamics and static pressures within the systems, defines and explains EL, friction rate, location, throw and spread of grilles, registers and diffusers. Includes a Software portion for Wrightsoft and will include Elite. The information covers efficiencies relating to design, installation as well concepts focusing on delivered efficiencies, operating points, fan and duct curves.
This class will consist of a 5-6 hour guided study session for the EPA 608 exam, followed by a closed book, online certification 
exam. This certification is required for all HERS 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.
This class has an online exam with an associated cost of $50 in order to receive certificate. Payment must be made prior to class to reserve seat. Please call for more info.

Class Overview:
This 1/2 day class covers Manual ‘J’ Sizing Introduction Manual ‘J’ Wrightsoft Set-up and hands on training Detailed Cooling Capacity Data Sheets Air Flow Calculation Worksheets.
Description:
This full day training class is designed to introduce HVAC Contractors, General building Contractors, and Mechanical Engineers to the process of sizing, designing and installing small Commercial HVAC package unit systems. This class includes three specific components: 1. Classroom instruction of the building science affecting equipment capacity and building loads. 2. Hands on training in the use of Wrightsoft™ to size small commercial loads. 3. Classroom instruction on the proper sizing procedures in ACCA Manual CS, and California Title 24 Ventilation Regulations.
Description:
This full day training class is designed to introduce HVAC Contractors, General Building Contractors, and Mechanical Engineers to the process of duct design and register selection when installing small Commercial HVAC systems. This class includes four specific components. 1. Classroom instruction of the ACCA Duct Design procedure. 2. Classroom instruction on effects of CFM, velocity and pressure on duct desgins and general airflow terminology. 3. Duct sizing practice exercises. 4. Register selection and placement.
Description:
This full day training class is designed to introduce HVAC Contractors, General building Contractors, and Mechanical Engineers to the process of sizing, designing and installing small Commercial HVAC Systems. The training class includes two specific components. 1. Review of all objectives and priciples covered in the first two courses of this series. 2. Hands on software exercises guided by the instructor to verify students can properly design an HVAC package unit system for quality installation, as well as properly design the duct system.
