Factory A/C
Have a 70 F100 with factory A/C.
1. Not very cold, but seems to cool better at idle and low speeds rather than highway. Still Runs freon I think.
2. When I run it for any time at all, I get condensation all over the floor. I've taken it partially arpart end the condensation hose is in place and connected.
Q1: This truck is restored and A/C hoses and all seem to be in good working order. What are the pluses and minuses of changing over to R-14 (is that what it's called)?
Q2: Any suggestions on stopping the flood? Is there supposed to be a gasket or should I put ina gasket or?
Thanks.

I've replace the R-12 with 134 on three of my vehicles and they work great. They all will freeze you out of the vehicle! Make sure you have a mechanic change it that knows what he is doing. Mine told me that 134 requires less compression than R12 and he has to adjust the clutch to compensate. I'm convinced this is a key element in a successful conversion. Cost is about $110 to convert. (Remove old freon, remove washers/seats, install new washers, re-oil and charge).

If you are running R12, it sounds like a classic case of low charge. If the compressor is cycling 6 or more times a minute at idle, in max cool, and the register temp is only in the 50s, a pound of freon will probably do the trick. I had the same problem since I had replaced my compressor last year. But get a book with a diagnostic chart to check out the system before adding the juice. I believe the other post about conversion is backwards; the 134 system runs much higher pressures which obviously can cause problems with marginal hoses et al.
