Amen, one of my biggest pet peeves!

Why do techs insist on adding more gas to a unit when they check it out. If the unit was performing well before the PM why would someone think they needed more freon. I wish home owners would wise up to the fact that an AC unit is a closed system and providing there is no leaks they should never needed freon added to them. My question is was the unit cooling well before the PM and if so I would question why the company added more 410a.
