    Was the return static taken between the air handler and the air filter. Or was the static probe placed between the air filter and the return grilles.

    No, use WD-40, its a water dispersant. Non stick baking sprays are oil, which will tend to make a coil have condensate going everywhere in a manor worse then you already have.

    Either R22 or R407C both work fine in the same evap coil. However, R407C has a capacity reduction over R22. So with r407C, you don't get the same amount of cooling, as you would if they had charged...

    I'd go with putting on the TXV. It gives a more consistent evap temp. Plus reduces the risk of liquid flood back to the compressor with a slowed blower.

    That thermostat is operating the system as it is suppose to. It brings on the cooling if the temp is .5F lower then set point, and shuts the A/C off when the temp is .5F above set point temp.
