I agree with you 100%.

In this case, assuming the OP is referring to the 1995 F150 in their signature, it came from the factory with R134a.

 

its possible that the seals or o rings are leaking. i would replace seals or if you want a automotive hvac guy can put die (dye?) in the system to track a leak

 

I agree, i am a bit leery of it so thats why I figured I would ask...


I am refering to the truck in my sig, and as for it coming from the factory with the conversion if it did cool, I just know it has the R134 system and some other AC system (i see other lines that look like AC coolant lines)

I plan to have it looked at and checked on Monday at the local BigO in the AC system check machine, to check both amounts of freeon and pressure and to make sure that both are returned to correct levels and then will be doing O rings after, also going to have the engine and oil pan checked for leaks (there are some) and will be looking to see what needs to be done to resolve the leaks also, or if its better to just leave them alone untill it gets a bit worse (cost vs time/labor situation).

 

I had the conversion done last June on my truck. The only thing they did was flush the old freon out, new compressor oil, do a pressure test, replace schrader valves, refill with dye added. So far, so good. Windows no longer steam up either in 45-60 degree rainy days either.

I asked the shop why the accumulator wasn't replaced or the hoses, they said it wasn't needed and the hoses didn't leak. Ok then. It cools perfectly, so, no complaints.

It cost me around 300 bucks too.

 

Update: I refilled my freon with two cans and the AC is responding much better now so I think half of a third can will be enough to finish it off proper...now I will be monitoring it to watch for any leaks

 

I have worked on automotive AC systems for 20+ years, not to say I am an expert, but IMHO the AC "conversion" you paid for is filled with pitfalls. I hope you have a warranty. Good luck.
