Graham. explained on 09/01/2016 :
I would like to know why air con units need regasing at all?
Vehicle aircons seem to need regasing almost as a matter of routine,
but fridges and freezers generally don't. Why?

Fridges and freezers are sealed, house, office and car a/c's having
externally driven moving parts using seals. The seals leak, you loose
the gas.
