During the furnace check, I thoroughly examined the modular furnace and its components. I discovered that the blower motor was running continuously. After inspecting the thermostat settings, I found that they were configured to keep the system running at a low speed constantly. I explained these settings to the client, detailing how the system is designed to operate in this manner. The client was very receptive to the information and expressed gratitude for the clear explanation. The system appeared to be functioning well, and there were no concerns raised about its appearance or performance. The client appreciated the detailed insight into the system's operation.
