Air Conditioner does not stay cold in my 1991 Honda Civic, freon does not hold, what is it going to cost me to get it working again?

Hi, it sounds like you have you have a leak. Bringing your car in for service for this kind of repair usually can cost several hundred dollars, 300 - 500 $. This problem is usually a leaky o-ring at one of the hose connections, so in order to find it you need to put a dye tracer in with the freon. There is possible ways that you could fix it your self. First go to your local auto parts store and pick up a can of freon with a sealer in it and give that a try, or you can go all out and get a kit that has what you will need to trace the leak, then you can replace the defective part and then re-charge the system.

You're going to need someone to put a leak detection dye in system and locate your freon leak. Also have them pressure test.

Is it the old R 12 Freon or the newer 134A.? If it's the 134A you can buy the stop leak/oil/Freon at Wal Mart for about $15. I've had good luck with it in several cars. Sometimes it takes more then one app of the stop leak. I do that first before I spent $300 plus on a new A/C overhaul.
