I have a 94 Accord and the AC system is completely empty. I got these freon cans w/ gauge to fill it back up. I followed instruction which was:

-Start Car
-A/C on max
-Shake can and push onto the nipple

Now when after I do that for several seconds, the needle on gauge goes to max when I haven't even went through half of the bottle and car starts idling up and down. Any ideas???

What are the high and low side pressures? Is the compressor cycling on and off as the idle surges? Did you evacuate the system before you started charging it to get any air/moisture out of the system?

you need to run vacuum on the system for like minimum 20minutes, then most AC system really only need about 3.5 lbs of refrigerant

Not sure where you are getting your info, but every car has a specific amount that is required, his Accord is 1.3-1.4lb MAX.
Here is a PDF. of all AC refrigerant capacities up to 1998 model Hondas. Free of charge. (bad pun, I know)

Seriously! you need the proper equipment to work on a/c systems..
You should let a professional do the work.A/C work requires certification and knowledge.
It's not like changing your own oil or plugs.This is much more involved and dangerous.

Yea, sounds like a professional should do this. What's the average price on a job like this?

Depending on the reason it was empty in the first place, an evac, leak check, recharge and system performance test can run anywhere from $150-$200.

he probably thinks u can charge an r-12 system just as easy but you cant. R-12 is very expensive

All the R-12 left in the world is either recycled or bootlegged and isnt worth a shit. It is illegal to manufacture so the stuff coming out of mexico that is illegal is highly overrated and mostly propane. It also is about the same price as gold is now. So its not even worth considering as a repair.

Definately agree with everyone else, A/C work, is for professionals. I would recommend taking it to a dealership, or some sort of repair facility certified in A/C or HVAC. Hopefully, your system is just low on refrigerant, and thee are no major leaks, because it can get very expensive. Also, im not 100% on this but i do believe you may have a veh. equiped with R-12, which in order to recharge, will require a conversion kit to change from R-12 to r-134, which can become quite expensive.

Repairs (if it leaks) can be expensive,but the conversion to 134a isnt too bad,Considering the alternative .If someone HAD R-12 to sell..how about 40 bux for 2 lbs R-134a versus 200 bux for 2 lbs r-12..That shit is out the door outrageous..
