Hello, I have a split system (FX16C-P/M188-417SMX) that cools my bridge. The Condenser is marked R417a, while the air handler is marked R22. I had a local HVAC guy out and the system is totally empty...we're pretty sure the leak was at one of the flare connections. My problem now is R417a is TOTALLY UNAVAILABLE in Canada! Can the system be evacuated and recharged with R-22? As I understand it the FX line was originally an R22 unit that was changed to R417a mid life cycle. Thanks!
