I live in the Southern California Desert and have a 4-ton Carrier Synergy 2000 (two stage scroll) A/C-furnace system. This was installed in 1995 and it has worked well and I have kept up maintenance/filters.
Now the evaporator coil is leaking and I am trying to decide if I should just replace the coil or bite the bullet and install a whole new system... something along the lines of a Carrier Infinity. The cost of the new system would be about five times the repair cost of the evaporator coil.
The tech said the current compressor tests well within rated amp draw. After yesterday's Freon charge I now get a 23 degree drop on a 110 degree day.
I would prefer to just replace the coil and get 3-5 more years out of the existing system, but can spring for the new system if that is really the best move. I realize this is predicting the future a bit, but do you folks think I can get three or so more years from the rest of this system, or is 13 years on the existing Carrier compressor/system the end of a normal life?
We plan to stay in the house.
Appreciate any advice.
