Another dumb question

Moisture left in the system is 1- non condensible causes poor performance. 2- turns oil to sludge and acid, causes txv's, orphises and small passages to clog. 3- causes copper plating which equal poor heat transfer.

Why would you open the circuit on your truck every few years? Unless the compressor has to be unbolted there is no need.

- Your talk so far just like one of those OEM trained idiots!!!... get your head out your arsse ... Its a big-truck and it is inevitable that the system is torn down every couple three years or so for any of - CAC replacements, radiator leaks, bad sensors, front end work of one type or another that requires the system to come apart, compressors failing / getting weak due to constant road use and commercial environment type of use, thermistors going bad, and the rest of what constant road torture and vibration related failures. - Your theory sounds ok to me but it is just not practical to be so touchy-feely with it in such an environment. -- STOP drinking the cool-aide and get back to reality.. and spit out that corporate bullshite that has no practical purpose except to over-think things and fancy-talk yourself into circles.

- My truck has more than a million plus miles on it and my AC has been apart likely a dozen times already... NONE of which was because of any of those issues you described as a contributing factors. - I have replace my drier only once in a million miles. - And the system still works great. - COME OVER AND PULL MY SYSTEM APART, SHOW ME THE COPPER CORROSION AND OTHER GARBAGE THAT YOUR SPEWING ABOUT -- YOU WELCOME TO INSPECT AND TAKE PICS, ETC. AND EDUCATE US ALL ON YOUR SUPERIOR (BULLS#HIT CORPORATE GARBAGE-BRAINWASHED) WISDOM!

(being sarcastic, not trying to be a meanie there)..

matter of fact... i have not seen a single truck AC system over here suffer any of those type of things... and I have seen a lot of them apart.


- Like Nilao said... those are great things to consider when looking at a home unit that does not suffer the fate of torture that an 80,000-lb big-rig and the roads do to A/C systems. theory and things to consider are good things to keep in mind but what you spewing is sales-mans garbage at best when it comes to the world of trucking.


-- and BY THE WAY!!!>>>> Anyone who has to have their system apart for a week, say because they are doing an in-frame... or for several days while its raining outside, etc... can simply put their dryer-accumulator in a dehydrator (or oven) for about 4-6 hours or so and bake it at 210F and cook off all the moisture, renew the desiccant medai from within it if they do not want to buy a new one to the tune of a few hundred bucks... if the spring in it is not worn out.

Trucking is simply a different world when it comes to AC work. - too much plastic, cheap-arsse compressors, valves and sensors that fail regularly due to vibration and road use, temp extremes, etc... blend doors that get sticky + their plastic gears warping and stripping out, constant battle to keep A/C running in a modern truck these days... They are way-over designed and a money-maker for the OE stealers$its out there and they know it.
