Easy task if you have experience with AC .If you've never worked on AC system or don't know much about them I'd suggest letting a shop do it .Refrigerant can be dangerous .

If it's low enought to trip the pressure switch, you really should do an evac an re-charge... not just add more refrigerant.

Just did this on the wife's truck. Got the vacuum pump and manifold gauges as free loaners at Autozone. Was fairly easy to evac the system and refill.

Did this as well on my girlfriends dads car. Worked like a charm, my first time ever messing with the AC. Pretty easy to do. California may have some weird EPA regulations since they hate their citizens, I hope you don't work for the state either

well.... i got a mechanic friend to check out my AC (currently works for Audi) and he said based on his own visual inspection that it looks like i may have just had a slow leak from possibly one of the hoses since there was a dark buildup around one of the hose fittings. he is likely gonna service it this saturday so hopefully my hot black stang will be cool again. i need to go to vegas end of this month and it will be hell (almost literally) without AC! i'll keep all posted on my AC issue for forum reference.

friend snuck my car into the dealership shop and recharged the AC with freon. apparently it was low which was all that was wrong with the AC. if it continues to run low at a faster pace, i will get it serviced more thoroughly. as for now, my stang is nice and cold again! i have a new appreciation for AC especially after this SoCal heat wave!

Step one in that line of thinking is to
FIND the leak and REPAIR it
Then eVac it and recharge it....
Freon does not just disappear into thin air in a properly sealed
AC system. There are reasons for laws concerning AC systems.
The more Freon you let escape into the atmosphere, the worse
it is for the enviroment.
Pay to get the leak fixed......

obviously this was a patch up job but my friend said he wanted to spend more time on it this weekend so we'll see. supposedly this is a common issue on many new cars of all makes.

Right on.. AC Systems are what is called a 'closed system'!!!

You gotta have a leak somewhere. I had an 89 Bronco and at the time, the design of the ford systems was such that the seals were prone to failure. Of course right around the time the warranty expires. I'm hoping that this has changed, but what I also remember is something about the systems becoming contaminated causing compressor failure and replacement - big $$$'s.
Good news you got it cool, but I think the advise here on finding the leak and evac/recharge is the way to go.

for sure.
