I have a 94 ex and i want to buy those recharging kit from autozone but im not sure how you charge it. Anyone here ever recharge their owned ac?? and how hard is it?

 

At my high school we have a machine that pumps the refrigerant out and pumps it in. Maybe you wanna try and find a place that has one.

 

iv seen little kits that you can buy at stores, but i dont know how well they would work. you are suppost to pull a vacuum before you recharge it at the shop. so you might as well get it done there. also. your freon shouldnt just disapear, it should last forever. it must have a leak, so recharging would only be temperary.if its suppost to run on the old 134 freon, then you cant recharge it. you will have to convert it over to 134a, i think its called.

 

If im not mistaken, the only refrigerant that was/is used in cars is R-12 and R-134a. R-12 isn't made anymore but if you find some you can put it in your car. Its like $60 a lb.

 

A 94 model should have the newer refrigerant in it. If you can find some in a kit, you also need the hookup to the can and the A/C system in your civic.
I've done it before on other cars, and you just add the refrigerant if you have a slow leak. By law, you shouldn't do it anymore since you're supposed to have a shop find the leak before refilling.
Some shops will just top it up if they know it's a slow leak, even though they're not supposed to.
