    Flushing R-22 from coil
    Can a 13 seer coil that is rated for R-22 & R410a be flushed and used for R410A? It had R-22 before.

    Yes if done properly and the coil/line set size matches the new outside unit. Also the expansion device or flow rater will also need to be changed when changing refrigerants.
