My unit is 20 years old and has been very satisfactory. The variable speed air handler was replaced 11 years ago due to a problem with the blower motor. Trane made me an excellent offer to replace the entire air handler which I accepted. Overall I have been very satisfied with the system which is still operating fine but I am getting concerned due to the age of the condenser unit. I will probably buy another Trane.
