Last winter my son-in-law had my Expedition and the AC bearing seized. The solution was to break the lines and pop in a new compressor but we did not have the system serviced.
I have a friend with the necessary tools and wondering if Duracool would be a better option than R134?
thanks

Normally I would say yes but I ran into a problem with my Chrysler minivan. The condensor/cooling fan is controlled by the head pressure. Since Duracool has a lower operating head pressure, the fan does not come on at idle and cooling performance drops off. The fan works fine and is also controlled by engine temperature if it is hot enough. Obviosly every manufacturer has different ways of activating and controlling the cooling fan speeds so this may not be a problem for you especially if the fan is engine driven.

My older Caravan was fine too but the newer ones use a totally different fan controller.

There may be pressure switches available with different set points. When
we first charged Stick's 96 Cad last month, we didn't notice that the low
pressure cutoff switch was leaking. After he lost the charge overnight,
the oil film around there registered, so we removed that purple-bodied
switch and took it to O'Reilly's. The only switch they had was
yellow-bodied (IIRC). We installed it, and Stick's happy with the
performance of the system -- but he's running about 21 psi and the switch
cuts out at about 20 psi, so he may have to add a little more Duracool
after a while. I suspect the switch's body color indicates the cutout
pressure -- with no proof of that WAG.

The Expedition has a clutch fan so no problem there, right?
I assume the lower pressure of duracool is still in the range of R134?

Dave: I put dura cool in my 2004 explorer. Same system as your expedition. Works wonderfully. Very cool. Of course we seldom get above 85, but even after a hot parking lot it puts out cold
Right away. Better than when i had 134a.
They make duracool here and they recommended it.

On the Chrysler, the fan is infinitely variable so the switch is a transducer not just an on-off switch. However, you may be on to something.

For somewhat more money, adjustable switches are available at your local air conditritioner parts outlet.
