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.
Class Overview:
This is a full day class. As more and more attention is given to Air Sealing of Homes in California what basics should everyone who is part of the audit team to the Air sealing team know as they prepare to seal Homes. The course deals with basic Air and moisture flow. The purpose is to assist prevention of homes that develop avoidable problems with some planning , understanding of moisture, pressure and heat flow dynamics. This is recommended for each HERS Rater, Mechanical Contractor or Building official involved in an Air Sealing Project.
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.
Class Overview:
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.
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
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.
