Which systems are more reliable, those that use R22 vs. R410a? Are R410a systems REALLY as reliable R22?
I live in a condo and replacing the refrigerant lineset would involve ripping up the ceiling drywall. My AC system is 20 years old. Wondering the best solution would be to get a new R22 system (with existing refrigerant lines) installed before 2010. If the existing system were to die after 2010, then only systems that use 410a will be sold, and I would have to hope and pray that cleaning/purging out the old lines REALLY is going to be sufficient for a reliable 410a system. What do you think?
Thanks,
J.
