Course: Residential Heat Pump Installation & Commissioning for Installers, Raters & Commissioning Agents P2
Transitioning residential and commercial heating and cooling systems from gas to electric is a key component in California’s plan to reduce emissions of global warming gasses. You, the field staff in the HVAC trades will be installing more and more heat pumps as electrification efforts continue to ramp up. It turns out that there are large variations in the operating efficiency of heat pumps that result from our installation and commissioning practices. This class will focus on installation practices, troubleshooting and commissioning steps that effect final installed efficiency. We will look at airflow, line set plumbing, refrigerant leak prevention, location and repair, heat pump controls and control settings. Both legacy systems and mini split systems will be covered. The course will be presented in two, three-hour parts.
