Great point on the HVAC 2 yr program (I took same classes in 1990 as a backup to plumbing). Refrigeration is the way to go,you have great insight/vision.
Current California Law states “no permit required for any repair work done on a single family residence, even plumbing, if repair is under $500.” or words to that effect. Change that law.
What is the difference between installing a water heater (permit,plumbers c-36 license required by law) and changing a washer on a faucet ( no permit, no license required) when in reality, both tasks require a breech of the potable water supply system. (opens the system to possible contamination). So why then is it allowed?
Many have died due to no inspection, no permit & sloppy work-9 members of a single family in Texas come to mind when a kid hit the water heater power vent pipe down basement with a football and the “power vented water heater’s fan caused carbon monoxide to spill taking 9 lives.(No screws [3 required]on each vent pipe joint) So codes do not need new reasons, just concerned citizens holding code offical’s accountable-laws are there.
Glad to discuss this, great things begin with a discussion.Motown
