I have a 7 year old trane dual-zone system, heat pump for upper level, outside AC/inside furnace for lower level, virginia climate. Home is 3000 sq feet, 4 BR upstairs, finished basement. Both are SEER10. The system has worked fine with no complaints.
Our service contract tech did his annual spring inspection today and told me that the compressor on the heat pump was getting noisy and that it might be time to replace it soon. But he mentioned that the kind of freon the pump uses wouldn't be available much longer so he suggested I think about replacing the unit at a cost about 3 times the cost of replacing the compressor, which he said would get me a more efficient unit with a higher SEER rating. He said the inside coil would need to be replaced as well.
Anyone have any thoughts? Is he accurate? Is the compressor something that I can run for a while longer and just replace when it fails or should it be replaced before failure?
Thanks in advance.
