Air Conditioning Question

Yes I have used the search button.
Yes, it is true, I don't know **** about air conditioning.

I have a 2006 H2 with 34,000 miles and I am the original owner. Although I have limited mileage, they have been hard miles, nearly all of them towing a boat in high heat for long distances.

I have used my A/C constantly in 100+ degee heat on a weekly basis during the summer. It is clear that the A/C has become less cold over the last year and is struggling to bring the temperature down to a comfortable level.

It has been a while since I was cracking open engine blocks, but hasn't A/C technology advanced that this could be a more serious problem than just doing a "recharge" of the system? I thought the freon days were over.

Any advice would be greatly appreciated. I have had the flash done a few years ago because the passenger side only pumped hot air no matter what I set the temperature at. Is another flash an option?

Well, you are right that they are not putting freon in new vehicles, but they still recharge them. I would find a shop that does AC stuff and go in for a recharge. They will check for leaks at the same time, and then recharge the system and you should be good for several more years.

Ahhh, good news. Thank you for the help.

I had my AC recharged on my 62,000 mile '06 this July at a Goodyear Tire Center while I was out of state. They tried to sell me a new condenser and separator, but I passed on that. So far it's doing fine and ice cold again!

Just recently, my 08 seemed to blow cold...and then not so cold air, - took it in the dealer, they diagnosed that the line had a leak. they replaced it. then, my left side wasn't as cold as the right side. they determined then...that it was a bad actuator. they replaced that...and now it is fine.

ac systems are so complicated.

Thank you fellas.

My AC was not as cold as it once was so 2 weeks ago I went to NAPA autoparts and bought the DIY recharge unit and after using it my AC got worse! :crying:
So I brought it to a Local Wrench who evacuated the system and recharged to proper poundage. Everything is Ice Cold again! :D
He said I most likely overcharged the system :raar: and that can make it not work just as easy as a undercharged system.

Didn't your refill kit included a PSI gauge so you could fill it to the proper pressure?

Yup! It had a guage built in to it so according to me it was correct. I guess the guage was a POS!

[PHATBOYPIMP]

Had the AC recharged and all is good. Thank you for the help.

Yep, let a pro do the recharge and don't let them put in any of the stop-leak crap some people are trying to push now.
