A/C Problems

[hondaman2169]

I need to re-charge my system but I don't want to go and pay a shop a lot of money to re-charge my A/C. Can I do it myself? My manual says that the system is pressurized and needs a professional to do it. Any help is wonderful.

Well I know you can buy the recharge cans, but they don't work great for a few reasons. Its hard to recharge it to the right pressure, it also should have a vacum put on the system first. Because if this freon got out, it means air got it more then likely. Pay to have it serviced is the best way. Has your car been converted over to R134? If not expect to pay a little to have it done because you can't get R12 anymore. How do you know it needs to be recharged? Is it a guess? Just because it isn't cold doesn't mean you need to recharge it, check to make sure the compressor is turning on as well as the fan.

you can get r12, its just a little more expensive. They even sell freeze 12, I guess its somewhat similar.

I'm pretty sure its illegal to buy now. It was banned, hence the introduction of r134, maybe thats only in Canada though.

[eric123]

Nevermind just checked Wiki, it says its banned in the United States as well.

Hello,

I have seen this done and I do not recommend it. Many times there is loss to atmosphere a large amount of refrigerant gas and this is very harmful to the environment. I have seen AC recharge deals run somewhere around 50 bucks and if you want to do this yourself it will cost a signifigant portion of that. My advice, go and get it done and save the hassle.

When I have the a/c on full power the air that comes out is almost hot. There is some coldness in it but mostly hot. If I don't need to recharge then what can it be then?

[hondaman2169]

The air comes out almost hot, there is some coolness in it but mainly hot. What could it be then?

My was like that last week. Nothing but hot air but sometime it get cool for a little then back to warm. Just need to recharge!

Did you convert your system to R134a before? If so Just go buy recharge can and charge it up. Cost me only $23

Your best bang for your buck is to go and have a evacuated and then recharged, you can do it with the can, but it won't be as cold, and could end up blowing the compressor, pay the $50, and have it done right.

well before you buy freon, check for leaks in your discharge lines. My lower discharge line was leaking so bad that R12 was leaking out ...w/in a month it was empty. So have someone put some dye in the system and then inspect w/ a special UV light.
