You can replace it now if a new one will increase the efficiency, power use, and your peace of mind. Or, you can just wait for it to stop working. But, I don't think anyone can tell you when it will fail, and I wouldn't spend any significant amount of money to repair it if it breaks down. Being out of town will not really increase the life span because you need to keep it running to control the humidity in the house.
