I was called to a home to inspect a furnace that was not working properly. Upon arrival, I found that the customer had turned on the system for the first time in a while and noticed a smell of propane and carbon monoxide. I inspected the heat exchanger and found a crack and a clogged secondary. The gas valve was also stuck open. The customer mentioned that they had been having a lot of issues with the system. I offered the customer a few different options for a new furnace, and they opted for a Goodman furnace with a 10-year part one-year labor warranty. I installed the new furnace and made sure it was working properly before leaving the job site.
