Upon arrival, I began by searching for a misplaced ball, which was not found. I then opened the coil door, discovering rust and mold. Further inspection of the system revealed additional rust and mold in the furnace cabinet. I conducted a thorough analysis using a combustion analyzer, identifying several issues that required attention. I explained the different readings to the client, ensuring they understood the necessity of replacing the furnace. The client is considering financing options, either paying cash outright or opting for 60 months of 0% financing through a qualified system. If the client approves and is available, the installation is scheduled for Monday.
