During the spring air conditioning maintenance, I meticulously inspected the American Standard heating and cooling system. I began by replacing the air filters to ensure optimal airflow and efficiency. Next, I cleaned the system's coils and fins, removing any accumulated dirt and debris that could hinder performance. I also checked the thermostat settings and calibrated them for accurate temperature control. Additionally, I examined the drainage system to prevent any potential leaks or clogs. Finally, I tested all components to confirm normal operation, ensuring the system was ready for the cooling season ahead. This comprehensive service aimed to enhance the system's efficiency and extend its lifespan.
