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.

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:
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.
