A/C question

[FiveLtrRiceEatr]

Alright guys,

My A/C seem to have went, it blows air but not any different temp air. My dad told me it needed a shot of freeon, but freeon is now illegal. So what do I do? I've heard of a swap to what they use now (I'm not sure what they use now, sorry for my lack of knowlege), so is this true? And if so what do I need to do or a shop needs to do?

thanks

matt

wow! just what I was looking for!

You can still get freon, it just costs more per pound than r134a.

It could be your A/C switch as well. If your car gets low enough on freon, the pressure switch will not allow the compressor to kick in. It's worth checking as well.

This thread may help as well. http://eleanor.pro3i.com/showthread.php?t=546788&highlight=a/c+switch

You can get recycled or recovered Freon (R12) but you cannot legally buy it in cans anymore. All the Freon (R12) that is around today has been sucked out of someone's dead or dying A/C unit. The one possible exception is somebody has hid some cans of the stuff on a back shelf in his garage.

They still sell R12, if they still have remaining containers since production of it ceased in 1995, you have to be licensed to buy it.

The shop I work for has a new can of R12 in the back. Converting to 134a would be cheaper, but it won't blow as cold. R12 does not need the pressure R134a needs to cool.

Now they are talking about two different options. R134a is more enviromentally freindly, but not very much. There is a new freon called R154a in development and testing. The other system they are experimenting with is CO2 A/C. That stuff would be completly harmless and would certianly shut the tree huggin hippy EPA's mouth but it would require over 2000psi, which could cause damage or injury so there is a liability there. You wouldn't have an evaporator leak, you would say "My A/C had a blowout, I need a new dash"

There's also Freeze12 which is suppose to be like R12. Not as good as R12 but better than R134a.

CFC = Freon (R12) or one of the similar compounds. As the name says, these refrigerants consist of chlorine, fluorine, and carbon, thus the abbreviation CFC.

From the EPA section 609 regulations covering motor vehicle air conditioning...
"Since January 1, 1996, it is no longer legal for CFCs to be manufactured or imported into the United States. Supplies of CFC refrigerant for equipment servicing can ONLY come from recovery, recycling, and reclamation."

As I said before, The one possible exception is somebody has hid some cans of the stuff on a back shelf in his garage

FYI: I have an EPA 609 Motor Vehicle Air Conditioning Certification.

It takes only a few minutes and $19.95 to get one of those.
