Your air conditioning system needs repair. Take it to a shop for a proper diagnosis. Simply recharging it with the do it yourself kits that are around is not going to do it, despite what everyone tries to tell you. If it needs refilling, that means there is a leak, and that leak could be microscopic, but until its fixed you'll just have to keep recharging it. some jobs are best left to the pros.
