Replacing a condensing unit with a higher SEER rating unit
The condensing unit for my central air system failed a week ago, and I'm trying to find out what my options are.
The technician is currently quoting $2500 to replace the existing 60,000 BTU R-22 unit with a similar R-22 unit. I'm not sure of the existing SEER rating, but since the system is about 20 years old I'm guessing around 6ish.
I also found a 13 SEER 60,000 BTU unit from the same manufacturer for $1500, or packaged with a matching 5-ton evaporator for $2100.
Would I be best off repairing the system as is with the $2500 replacement condenser, or is it possible to update the system with a higher SEER R-22 condenser?
Or should I just call it on this system and replace both the condenser and evaporater with an R-410a system + additional line upgrades, etc, and about how much would that cost (maintaining the current rating of the existing system)?
