Upon arrival, I conducted a thorough inspection of the furnace system to ensure it was operating correctly. The thermostat was exhibiting unusual behavior, failing to maintain the desired temperature settings. I began by examining the thermostat's wiring and connections, ensuring everything was securely and correctly installed. After confirming the wiring was intact, I tested the thermostat's functionality using diagnostic tools. The issue was identified as a faulty thermostat, which was promptly replaced with a new one. Post-replacement, I calibrated the new thermostat to ensure it accurately maintained the set temperature. The furnace was then tested to confirm it was running efficiently with the new thermostat. The system is now fully operational, providing consistent and reliable heating.
