Chive So Hard
I'm getting ready to move my King Ranch and I down to Florida and really need to get my A/C serviced soon. It hardly ever works now and I have recharged it a few times. Hopefully not an epensive fix.

In reading through some of these posts, it leads one to think that freon goes stale, and a recharge/replacement fixes it. Freon does not require any sort of flushing or replacement, unless there is/was a leak!
In most cases, I'm betting that these places that serviced an older automotive A/C system replaced the dryer; it's used to remove moisture; especially if there was a leak. When there is a leak, outside air is drawn into the system, along with moisture, which is what the dryer is used for; to remove moisture.
Anytime an A/C system is serviced (I.E. a compressor, evaporator, or pressure line) is replaced, the dryer is replaced too, as once an A/C system is "opened", it effectively has allowed moisture to enter, and this will drastically effect the efficiency of the A/C's function to cool.

Bucko that is an excellent point. The Freon, does NOT go stale and does NOT need servicing like engine oil or other automotive fluids.
If I had bought my truck new I would have known all the history, I did not however I got it about 3 years ago and it had about 100k miles on it already. And I noticed the AC wasn't as strong as I would have liked. That was only when the temps were around 100 and the humidity was up as well.
When I took my older car in to have it charged I mentioned it to my mechanic. He said he would bet it was low, just due to the age of my truck 9 yrs and the mileage. He was right the system was low. Not terrible but a bit low. He went a head and evacuated it, because I didn't know the history, held a vacuum and then recharged. He had to add another 8oz then what he took out. He stated that "leakage" is considered "normal" with the R134a systems.
All I know is now my AC is much colder when the temps were up. I wish I would have checked the vent outlet temps.
Thanks for the good points Bucko and the clarifications. You are absolutely correct.
