Upon arrival, I conducted a thorough inspection of the furnace system. I checked the thermostat settings and ensured they were correctly configured. I examined the air filters for any signs of clogging or dirt accumulation and replaced them if necessary. I inspected the furnace's electrical connections and components for any loose wiring or damage. I tested the ignition system and burners to confirm they were functioning properly. I also checked the heat exchanger for any cracks or leaks. After completing these checks, I started the furnace and monitored its performance. The furnace operated smoothly, with no unusual noises or performance issues. I verified that the heating system was delivering consistent and efficient heat throughout the space. Overall, the furnace is in excellent working condition.
