Upon inspection, the secondary heat exchanger was found to be clogged, preventing the unit from functioning properly. I carefully unclogged the heat exchanger, ensuring all debris was removed. After the unclogging process, I successfully got the unit up and running. However, I noticed severe damage caused by condensation within the furnace. I informed the customer about this issue and provided a detailed estimate for the necessary repairs. My goal was to ensure the unit operates efficiently while addressing potential future concerns.
