If older then 95, it runs r12 refrigerant, and you need to have a pro use a recapture machine for the newer formula conversion. If 95 or newer, simply remove the low pressure line cap, plug on your 134 refrigerant w oil can, and fill with vehicle running and AC on. Do not over fill, most these DIY kits have a gauge, so keep it in the green.
if you need to recharge your ac there is a good chance that you have a leak and should have the system checked for leaks and recharged by a professional. This is also a good idea because you could have other issues such as a faulty pressure valve, blown fuses or broken wires causing your ac to not operate.
If you are confident it just needs some gas then home charging kits can be purchased from any automotive store. your looking for a can that says 134A this is the gas used in all modern ac systems. older vehicles use r12 and require a retro fitting kit to run 134a.
once you buy the stuff and the blue hose required to install it (sold separately or in a starter kit), you hook the can and hose onto the low-pressure port of the ac system often capped with a blue cap and is the smaller of the two fittings. With the engine running and ac put on high turn the valve on the hose to open the can and let the gas flow in the system. allow it time to work its way out of the can. your ac system may require several cans to fill it. If you look under your hood you should see an ac sticker that has the proper amount of gas required - do not exceed this amount. because you have no idea at this point how much gas is in the system you need to pay attention the a couple things. does your ac blow cold now and how long does your ac compressor stay on. if your compressor is cycling fast (less than a minute between start-stop-and restart) you need more of a charge.
You cannot recharge the unit yourself. Due to the Montreal Protocol and the clean air act, you must have a certification from the EPA to purchase refrigerants.
Recharging a window air conditioner is not necessary. Refrigerants are not recharged unless the closed-loop system is leaking. It may only need a little bit of cleaning.
