I have a Carrier Synergy 2000 central AC, and since it is right outside the bedroom window of the home we just purchased, I am looking to move it about 30 feet. Since it is 15 years old, I am also looking to upgrade the efficiency, however the $14.5K I was quoted from a local pro to put in a new unit (and therefore, a whole new HVAC, which surprised me) is way out of my price range. Is there much useful that can be done in the line of servicing/reconditioning the existing unit? And would it make sense to replace the R-22 with R-410A coolant?
Thanks!
