I thought I saw a DIY article on recharging your AC on here before, but I cna't find it again. (can't search for the word AC).

could someone point me to that article again??? :thumbup:

 

better watch out that isshhh is dangerous you can lose alot of money if you let any a/c out and someone fonds out about it i am a/c certified is why i know

 

nah ur car is newer they have special kits to recharge it, u just have to hook into the low pressure line heading to the compressor, on our older cars they use r22 refrigerant which is extremely hazardous, and we cant do it without beign certified, and its a 10,000 dollar fine i believe to leak refrigerant into the atmosphere, but thats just off the top of my head

 

newer cars have different a/c systems that are easy to recharge, u just have to buy the cans of refrigerant, and the hose necessary to put it in and test the pressure.

 

Old cars use R12, you can't buy that without a license.
Newer cars use R134a, you can get that at WalMart.
Honda switched over in early '90s, my '95 is R134a. There will be a sticker in the engine compartment saying which it is.

You need pressure gauges for either type, & the correct pressures are different.

If your expansion valve or receiver/dryer is plugged, and you just add a can of refrigerant, you could really hose up your AC. So make sure you know what you're doing.

 

yah the r134 is really easy to add, u just have to make sure u are adding it to the low pressure hose instead of the high pressure line, if u have a book on ur car itll tell u which is which.

 

Yeah you should be using r134a unless ur car is real old. The r12 stuff isn't any harder to recharge, my dads 87 sentra uses it, the can of stuff is just harder to find (actually pretty easy if you know people :naughty: ) You can actually get some on ebay for pretty cheap nowadays.

 

hey my car isnt old? grrr, and as for recharging an r12 system urself i wouldnt do it, but then again i wouldnt pay for someoen else to do it either cuz its expensive cuz those guys have to go thru certification jsut to use it. and there are huge fines by the epa if u leak the stuffinto the atmosphere, HOLY Sh!t there are tons of ppl selling it on ebay, isnt that sneaky, says u have to be epa certified in order to bid but hey who are they kidding cuz u know the sell it to whoever wants it.

 

My AC isn't working. Took it to a garage, the guy says he's going to charge me at least $1000 to retrofit to R134A (my car is currently R12). Screw that. Got on HAN this morning looked at some threads. I'm gonna have them evacuate my R12 for $69.95. I will do the retro fit, (retro fit kit at Autozone for $35) then fill it up with R134A. Anyone see a problem with my plan? I hope it works... it's getting HOT!!

Of course, this is all assuming that the problem is the refrigerant! Will they be able to tell me if there is a leak from sucking out the R12?

This sucks.

 

maybe, maybe not thought depends, if u are leaking refrigerant u will definitely be able to tell when u start to fill it up with r134
