Upon arrival, I conducted a comprehensive performance maintenance check on the furnace system. I meticulously set up for combustion analysis, temperature split, and static pressure tests to ensure optimal performance. Each mechanical and electronic component of the furnace was verified for proper operation. The blower was inspected for cleanliness and any signs of bearing play. Additionally, I checked the heat exchanger to confirm proper venting of flue gas. Throughout the process, I engaged with the homeowner, discussing indoor air quality products to enhance their living environment. The furnace is currently operating efficiently.
