I would have the system rechecked by the shop that serviced the system for you. If the system is low or out of refrigerant and they cannot find a leak then I would recommend having them recharge the system and to put some dye in it. This dye will help them locate where the system is leaking from. It can be very difficult at times to find an A/C leak since refrigerant is a gas at atmospheric pressure. The dye will leave a residue that can be seen with an ultra violet light. A common place for an A/C system to leak is at the service ports. New valve cores can be installed to repair this problem. - Top Tech Automotive
