SOURCE: Recharge My AC Unit

The system needs to be accessed through what is call a tap valve. After a tap valve is in place a high vacuum should be pulled on the system down to 500 microns to remove air and non condensible gases along with any moisture from the system. Then the charge should be weight into the system according to the name plate with the proper type of refrigerant, generally Refrigerant 22. An alternate method is to charge the system by superheat of the gas returning to the compressor. Ambient temperature determines how high or low the superheat should be.

SOURCE: air conditioner does not cool

Well, letting things sit that long isn't good for them. It probably lost it's charge of freon.No way to fix that.

Check the temperature of the air coming out the vent If it's more than 10 degrees below the air going in it's ok. If it's the same temperature, the condensing system may be not working. The compressor may just be a quiet one!

It's R-22 and you need to be licensed to handle it, if you're not a A/C service technician or fimiliar with charging an A/C system, then it is best to have a Coleman Service Technician to charge it for you.
