Country Coach OTR Air

[truk4u]

Dale,

If the dryer was exposed to air for sometime by unhooking the line, shouldn't the dryer be replaced? My understanding is they are very susceptible to ambient air moisture. The desiccant absorbs the moisture and will quickly become non functional.

You're more familiar with this A/C stuff than I am, so still learning...

Dale,

I didn't see it mentioned but remember, do not forget to replace the dryer.
Let us know how it all works out...

Tom/John,

In post #13, I mentioned the dryer replacement. I have taken the line loose since then, but I covered any connections with plastic and duct take to minimize any moisture in the system.

When I was flushing the lines, I removed the high pressure line from the dryer and noticed that it spit oil out. I called the A/C Supply House and thy said that was normal.

You do have me wondering now if I should replace the dryer again, but I doubt that any shop would under the same circumstances? Of course, as Denny mentioned, many shops don't do it right either. I may ponder this a while before I try recharging the system today.

I decided that since I had taken the lines off the new drier a couple times, I would replace the drier the second time just to be sure before I charged the system.

After changing the drier again, vacuuming the system for an hour and charging with almost 11 cans of freon, the air was 36-38 degrees coming directly out the duct on top of the evaporator. I sprayed all fittings with A/C leak detector and didn't find leaks, so hopefully, everything is okay. I am going to give it a couple days to make sure everything is all right before I close up the kitchen cabinet and the bed frame.

After purchasing the new compressor, 2 different driers, 2 expansion valves, O rings, freon, and flushing fluid, I have ended up with $888 in the entire job. If I include the new vacuum pump, A/C gages and a set of offset wrenches, I would have another $136 invested, making the total $1024. Of course , I hope the pump, gages and wrenches will last me for the rest of my life.

Congrats Dale,

if you have cold air in NC and the o/s air Temp is about 65 degrees, you will be designated as the unofficial POG CC AC XPert. I am certainly glad you are on board. I am sure that was a big job and well done.

Thanks Roger, I hope it will be worth it. I have never even tried to use it while on the road. Our dash air is very cold, and has always supplied plenty of cold air while traveling. I just didn't like the idea of the OTR not working properly.

Dale,
An air conditioning seminar in NC would be greatly appreciated! Please sign me up.

Hey Dale,

Count me in on that seminar too.
