OK here is a qestion I have,if you replace a older R22 evaporator coil with a newer R410A Coil will you have to replace the out side condencer?if so can you just use 410a in a r22 system?
# 2 question is: can you convert a stright cool air conditioner to a heat pmp by putting a reversing vave in it?
I an just curious.:D
