I was told that th state of California requires an inspection after the new system is installed. Is this correct

Hi, Patricia. There are three steps to fulfill the state’s permitting process. The first step is to pull the required permit with the city’s building department. The second steps is to have the newly installed system HERS tested. A HERS test is a duct pressure test and refrigerant pressure test. Once that is completed (and passes) the third and final step is to call the city building inspector out for a final inspection. The inspector will request the HERS test paperwork. Hope that helped.

Don't know. Google it
