I have a 15 ton situation where the R22 evap coil is virtually inaccessible and cannot get a new R22 15 ton condenser, but can get an R410A one.
What capacity loss would be there using R22 or R407C in this unit? (We may be able to live with it)
Alternatively, what about changing the compressor to one designed for R22 or R407C?
I realize the pressure switches, etc would need replacement.
Thanks
