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.

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.

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.

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
