TXV or fixed
What is an easy way to tell if your AC has a TXV or a fixed orifice? That is without cutting into sheet metal to look at the evaporator coil. I most times just go by the amount of time it takes for the pressures to equalize but I'm sure there is a better/easier way.

There is no other way to be sure other than to see the metering device (txv or piston)
