“... not to mention some of the replacement refrigerants are more toxic than the old refrigerants.”
And more dangerous to handle.
You aren’t kidding. The small tanks and equipment using freon to very effectively clean circuits boards were replaced by monstrosities that required their own room, loads of hazards and didn’t do the job nearly as well. Later, the soldering materials went through changes to try and adapt to these issues. All for what I viewed as a HUGE waste of money, resources, and quality for distorted conclusions that met the greenies’ agenda.
