Cold air isn't cheap unless you do it yourself. The gasket kit that was spoken about above is more of an O-ring kit. All fittings are sealed with little green O-rings. The whole kit is very inexpensive. You might as well replace the orifice tube tube as well since you'll have the system all opened up. Thats sort of a refridgerant filter/regulator to simplify it, and costs a grand total of no more than $3.00. It's found in one of the aluminum tubes. It comes out with some needle nose pliers. Closing everything all back up tightly and promply is a good idea because the dryer (the aluminum canister) is designed to absorb moisture in the system and once exposed to the atmosphere it will begin to absorb the moisture out of the air, and it can only hold so much moisture. After all said and done Inter Dynamics makes an affordable and easy to follow R-12 to R-134a retrofit kit. It comes with everything needed to convert and charge your A/C system with the new R-134a refridgerant, even a step by step DVD.
