Recently, I conducted a comprehensive furnace maintenance service. This included a thorough inspection of the furnace components, ensuring all parts were functioning optimally. I cleaned and replaced the air filter to enhance air quality and efficiency. Additionally, I checked the thermostat settings and calibrated them for accurate temperature control. I also examined the ductwork for any signs of wear or blockages and provided a detailed estimate for duct cleaning to improve overall system performance and indoor air quality. This proactive maintenance will help extend the life of the furnace and ensure it operates efficiently throughout the season.
