First you need to find the leak, you should never lose refridgerant unless there is a leak.
where do I add freon to my air conditioning unit on a 1997 chevy truck?
A General Electric dehumidifier uses a sealed unit that does not have any way for you to add Freon to the unit. If you want to add Freon, you have to first install saddle valves to the dehumidifier.
In order to buy freon you need a license, therefore you shouldn't attempt to add freon. Call a contractor to service your unit.
Adding freon to an air conditioning unit should only be done by a certified technician. It is in fact illegal for anyone to add freon to air conditioning that isn't properly certified, so one would add freon by calling in a certified technician to do it for them.
A freezer from 1970 and for many years after requires R134 type freon.
RV refrigerators do not use freon but rather ammonia. The ammonia is in a sealed unit called the cooling unit and you cannot add ammonia to this unit. If it goes bad it has to be replaced.
You have to add a valve to the dehumidifier in order to put Freon in a GE dehumidifier. The reason you have to add the valve is because dehumidifiers uses a sealed unit.

To know when an air conditioning unit (non-window unit) needs to be charged (needs freon), it will not cool properly or you can test it with the appropriate gauges (see related link below).
