AC Takes forever to blow cold.

Whoa take it easy. I planned on doing that I personally don’t know how to bleed the system so I assumed my mechanic would. Evacuate would’ve been the better word thank you.

Are you a Trump supporter that doesn't believe in Global Warming and bleeding refrigerant into the atmosphere doesn't hurt the ozone layer?

Yep.


Or to be even more precise I lived thru the crap of having the r12 removed from the market for the ozone safe 134a. So its 134a now. We were told by the powers that be that the 134a is safe for the environment and the ozone layer so we had to quit using r12.

Well my systems seem to vent that ozone safe 134a around servicing time with no remorse from me thank you.

R-134a is a very safe refrigerant with an ASHRAE safety classification of A1. This means it is not flammable and has very low toxicity levels. Because HFC-134a has no chlorine in its molecule, it has a zero ozone-depletion potential (ODP) and doesn't deplete the stratospheric ozone layer

So if it gets vented I lose no sleep over it. Of course whenever any of my vehicles need servicing ac wise the 134a seems to just leak out mysteriously. No idea how. I guess gremlins.

I was a shop owner during that time and it wasn't fun. Up here we were told "NOT AS HARMFUL to the O-zone layer/environment" but still needed to be recovered. So buy or build a second recovery unit is what we did. I guess it wasn't till 2007 till the EU came out with some actual measurements of how harmful each gas is.

My take on R134a and venting is pretty simple:

It's the EXACT SAME CHEMICAL that is used in canned air dusters; yes, really .

Many gas dusters contain HFC-134a (tetrafluoroethane), which is widely used as a propellant and refrigerant.

The entire fill on most AC systems of a modern car are less than two cans of "duster" and plenty of "hair spray" type of products use the same as their propellent.

I have no problem whatever with a shade tree venting every 5-6 years during a major AC overhaul any more than I would have a problem with using R134a for chasing dust off a camera lens.

The product also is sold for freezing pipes where an entire can of 16oz is dumped onto a water pipe to freeze the pipe.

Clearly if the product is used very commonly as a propellent and for freezing things it is not a big global warming gas When used in a non-commercial way.

It's good that commercial use is regulated because shops that do 100s of AC repairs concentrate that quantity and it's a lot of needless gas venting that regardless your "political motivation" behind the global warming viewpoint it's just plain pollution simple as that.

We all polite, all day every day, minimize as you can but put the effort where it counts. 12-16oz of R134a venting to the atmosphere every few years is *not where it counts* it's absolutely negligible, your farts are literally 1000s of times worse on average.

Since I do manage a few family cars and happen to have a vacuum pump to evacuate and have a use for R134a products (pipe freezing and chasing dust), I've used cans of R134a for "dusting" because they don't have the "bitterant" that makes them WORTHLESS for cleaning as you just sprayed "skunk" on whatever you tried to clean.

Rather than buy "canned air" I'm going to try to recycle any "freon" I pull from cars, it just delays the inevitable but why just waste what I can use purposefully!?

Where does that captured R134a go? Logically it would go into those dusting cans but they would have to be able to clean in to remove the carcinogens etc.

Oh: fun aside: "green gas" for airsoft rifles is PROPANE. Don't believe me? Shoot your airsoft rifle over an open flame! Mine makes a beautiful flame puff about 10" long and when shot in slow motion is awesome!

Easy for you to say, you don't live here.

Update on Freon 134a as it relates to the effect it has on our atmosphere.

https://www.nytimes.com/2007/12/02/a...es/02COOL.html

If you don't want to go to the website and read about it here a brief synopsis of it.

In wide use for little more than a decade, the shortcoming of R134a is revealed by a standard measurement called the Global Warming Potential, established to compare other gases with the most plentiful greenhouse gas, carbon dioxide. The warming potential of R134a refrigerant is 1,410, meaning that the release of one gram of R134a would have the same global warming effect as releasing 1,410 grams of carbon dioxide. The warming number of Freon-12, the common auto refrigerant used into the 1990s, is 8,500.


I'm just trying to leave the world in the same or better condition for my kids and their kids.

From what I found and what I experienced it goes like this if its the compressor.

1. Randomly doesn't come on but if left running a bit it cools and cools great.

2. 2 to 5 minutes of no cooling and then cools great.

3. From this point on it just gets longer and longer before it will cool but once it starts its will cool great till its left sitting for a long time usually overnight.

The easiest way to look at it if its the compressor then it will not cool when you first crank the car for the day and after driving a bit or just letting the car run it will start cooling perfectly and keep cooling great till the car is cut off and sits for awhile usually overnight. Then the process starts all over again.

If it never cools or stops cooling then its not the compressor.

So mine always cooks at first startup. Then randomly while driving it's like someone hit the AC button. It just stops cooling.
It will slowly go from a little cool, I guess as it pushes out the cold air. Then it's just blowing air the same as outside.

If we stop and go somewhere. It comes back on and works again. Seemingly the longer you stop, the longer it goes before it stops cooling again.

I haven't checked for any hvac errors yet, but any clue?
If the clutch is faulty, will it throw an error for the hvac?

Sounds like the exact opposite of mine.
