Joseph,

If the unit holds less than 50 pounds of refrigerant, IT IS LEGAL to
add refrigerant to a leaking system. Re-read the Federal Register, all
84 pages of it. Or read the 5 page summary. Both will tell you the
rule against topping off applies to systems with 50 pounds or over and
a 35% annual leak. Smaller systems can have freon added as long as it
is not leaking so bad it goes SSSSSSSSSSSS!
