The fitting you are talking about is called a Schrader valve. It should look
somewhat like the air filling gizmo sticking out of your car's tires.
There is a tool with a pair of gauges on it designed to re-fill refrigerant
lines. It allows venting of the gas in the lines as the new freon goes in.
There are different refrigerants; find out what your unit is designed for.
If the unit is low on refrigerant there must be a reason why. Usually the
seals on the pump but sometimes a loose/broken hose or fitting will be
found. Don't bother refilling before you find out why, you'll just be
throwing good money after bad. Legally, if you need to replace the pump, you
are supposed to recover the refrigerant first so as not to cause a spill to
air.
Freon causes some people to think the world is warming up.
