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.

Class Overview: This training session covers issues and cautions that anyone involved in air sealing needs to consider when tightening a residential structure. It builds upon the principles in Building Energy Science Basics 100. A checklist of inspection points is provided as part of the training.
