Dash / chassis air conditioner on FC

[Chuck Wheeler]

You are right about the Expansion Valve Mike, it has to be replaced. You
only want to charge a R134 system to about 80% of the quantity of R12. R134
does not have the tolerance that a R12 system does for over or under
charging and it takes a different amount than R12. We have found that at
about 80% the system will function a little weaker than a R12 at idle, and
equal to or better than a R12 at running rpm. Except for my bus, which
didn't work out, this applies to the cars and trucks we have done. The
hoses in our BB were not lined so I lost too much Freon through the hoses
and it was too much work to replace them. I also decided that I did not
want the power load on a 210NA.

134A likes more condenser, you can't have too much. I used the old hoses,
new blower motors and had to change the expansion valve, stuff got in it.
Flush every thing you want to reuse and do up a new EV. It will all be good.

Thanks for your experiences and advice here! That really helps. I'm
going to try my luck with the existing hoses. I'll take it to a local
shop and see if they hold a vacuum and have them cleaned out. If that
looks good, i'll put on a new compressor and probably condensor, and
(hopefully) go happily down the road as cool as I want to be.

I did look into alternatives. There are aftermarket units that are
made for trucks and tractors that I could have used. They were
self-contained and the compressors would run off of 120v. After
talking to one of these manufactures (http://www.danhard.com) I decided
against it just because of capacity. The chassis one should put out
around 36,000btu. While even the largest 120v one would be 15,000 btu.

Thanks again,
Alan

Before I converted to R134 an a/c technician advised me that my expansion valve
was inop. My expansion valve is a major job to replace because I think the bus
was built around the valve and the evaporator. I did not change it.

Everything works fine after charging the system with R134 to 80% of R12 value.
I also changed the dryer and the compressor oil. I will see how it does over
the long term. I can always tear the bus apart later, if necessary.

Just reporting here. Please do not do what I do unless you are prepared for the
potential consequences.

I'm still wondering about the a/c tech.

When I need a part, I go to the mfr. site, do a distributor search and go from
there. A few calls to various suppliers will reveal who has inventory and who
only orders when needed. The larger stocking dealers will usually give up the
good price as they like to turn over inventory. Any thing you need is as close
as the UPS truck. My local distributor is nice to deal with, but I have to stay
on top of them on pricing
as they are greedy and it takes them too long to get parts they don't stock.
Red dot has a good site, in fact I found the unit I decided on and told my local
guys what to order.

I paid around $800 plus shipping for a 6260 a couple years ago, so that may be
alright. Might pay to make sure you are dealing with a volume dealer. The AC
works real well with that big unit on the roof.

Thanks for the information, Mike. My dash AC is 18000btu and the 6260 is
38000btu and the 4500 is 45000btu. Why did you choose the 6260 over the 4500, I

Better air flow thru at speed and it's twice as big as the original unit. Flush
the system well, make sure no stuff is in the lines, nooks and crannies. New
expansion valve is a great idea. I got to charge my system twice because I over
looked the valve first time.

I found the 6260 here in Dallas for $670. TT A/C 866.884.8822. (Mike
there was very helpful.) It is my understanding that when you switch
to r134a your weak link in terms of capacity becomes the condensor.
r134a needs more condensor than r12. By increasing the condensor, you
greatly increase cooling capacity. After that, (again, my
understanding after talking to multiple people), your evaporator would
become the next constraint in the conversion. I'm hoping it isn't
that big of a constraint as I'm not planning on replacing mine at this
point.

I don't think you would ever get 45,000 btu out of your dash air. I
