I have a bad condensor that is 20+ yrs old. I need to replace it but my furnace is a five year old Ruud UGPH-10EAMER gas furnace.
I am wanting to relace the condensor only with one that is more efficient and uses R410A. What considerations are there when trying pick compatible components? I have heard people say they replaced coils in their furnace when switching condensors. If anyone can shine a light on this, I would greatly appreciate it.
if you don't replace the coil you will have a less eff. system then your old one . I know its counter intuitive but its common knowledge in the hvac world and backed up with studies done by mech. int. magazine. you should also replace the line set when you switch refrigerants that use different oils the new poe oil doesn't mix with the mineral oil your old system used and not replacing the piping can decrease the life expectancy of the new system
The condenser should be matched with a properly sized evaporator coil that is rated for the same refrigerant that is in your system. Given that an average AC evaporator is about $250-400 plus labor to install, why would you take a chance of having the whole system screw up by 1 faulty component. Trust me...do it right the first time and you'll never regret it again.
