With a 28 year old furnace and air conditioner, the bad news is I will be replacing them both -- ac was no longer working and both are quite old. I was thankful that the same technician who came out 1-1/2 weeks ago was able to return so quickly to evaluate what went wrong with the system. He laid out the options and we both agreed on the direction to go. I appreciate his knowledge and ability to quickly diagnose the problem.
