I thought the orifice tube was right before the evaporator. Any particular reason why the accumulator and liquid line are so cold they have water condensing all over them? I could see if the orifice tube was on the condensor outlet but I think its up on the evap.

I think you're confused as to which line is which.....

The accumulator should get cold. The suction line (large, return to the compressor, carries gas which absorbed pass cabin heat while it was in the evaporator) should also be cold. The liquid line (small line, carries high-pressure condensed Freon from the condenser to the evaporator) however should be slightly warm, but no more than a few degrees above ambient. The orifice tube is in the fitting where the liquid line hooks to the evaporator.

Your probably right (confused), lol. As long as the accumulator is supposed to get cold I think I'm OK. The line I called the "liquid line" that is getting cold enough to form condensation goes from the condensor to the accumulator. I don't think I have a problem based on what I've read.

Thanks for letting me know where the orifice tube is.

There is no such line. ????

There's a medium-sized line from the compressor outlet port to the condenser coil (high-pressure, hot gas); a small line from the condenser to the evaporator coil (high-pressure, ambient temp liquid); the liquid passes through the orifice tube from high pressure to low pressure and evaporates, cooling itself; passes through the evaporator coil, absorbing heat from cabin air along the way; exits the evaporator and flows through the accumulator, while still somewhat cool; travels through the suction line from the accumulator to the compressor intake port.

At no point are the condenser and accumulator adjacent to each other in the flow. No line goes from one to the other.

But you're right, I don't think your A/C has a problem.

Is anything actually freezing over, or just sweating? Out there in South Florida expect to see a lot of condensation. That's just what happens in humid climates.

FIrst, it must be the suction tube. Its a largish line extending straight out from the accumulator towards the front of the engine compartment, it goes down and towards the front of the radiator (which is why I thought it was a line from the condensor to the accumulator.)

Its only sweating, its very cold, enough to form dripping condensation, but no frost (at least not yet).

I wonder if I could use some of that cold in the engine compartment (oil cooler or something?
