For me, I've never cared for the type of valve it might be, R12/R134a. Temp is temp. Yet to find a TXV that can determine what refrigerant is in a system. I'm sure there is a theory on this I have not followed. But that's just my 2 cents.

Hey all, thank you very much for the quick and detailed responses. I spoke to the owner of the car about your recommendations and he showed me that the txv in the car is now making a loud "rusty gate" whine whenever the AC engages under acceleration. It's still cooling, but the sound is obnoxious and he wants it gone.

We're going to go ahead and kill two birds with one stone by replacing the txv with an OEM one. While I have the evaporator out of the car I'm going to inspect all of the seals and blend door to ensure that air isn't able to bypass the coils and that the blend door is actually physically sealing.

Once I'm done I will post again to let you know whether the issue is solved or not. Cheers and have a good night!

Two of my co-workers had early 1980s Accords in Phoenix and their AC was very good, very cold.
