So was going to get this done, but the bloke at Natrad told me that it is illegal to re-gass my aircon without changing my reciever dryer. This is news to me, as in the past i've gone and had it re-gassed no questions asked.
It's an extra 130-odd to get the reciever dryer, so obviously i'd rather not have to buy it, so what is the situation? do i actually have to purchase a new unit?
