Question #1 My Rheen Air Handler unit model #TWLE036P13F80 SERIAL 3 3424XSM2V is a R22 system. I want to change out my condenser unit which is a R22 system with a R410a. Will my evaporator handle the new R410a unit? Question #2 If I decide to change the evaporator can I just use the current model number and tell suplier I want a R410a evaporator? Thanks, John
