I recently installed a non matching evaporator and condenser both 410A on a high velocity air handler. I need to get my hands on a piston or TXV for the system. I am unable to find any information on the coil supplier online. Since the coil was not purchased through me I wonder what other means of finding out exist?
Who makes the evaporator coil and outdoor unit?
I don't see why you couldn't use a universal TXV rated for 1.5 ton and 410A.
Make sure, if the coil is on the return side, that you install a freeze stat to protect the heating coil, in the event the unit ices up.
