I conducted a comprehensive maintenance check on two Lennox HVAC systems. The first step involved inspecting and cleaning the air filters to ensure optimal airflow. I then examined the condenser unit, checking for any debris or obstructions that could hinder performance. Next, I tested the thermostat settings and calibrated them to ensure accurate temperature control. I also inspected the ductwork for any leaks or damage and cleaned the evaporator coils to enhance efficiency. Finally, I performed a thorough inspection of the electrical connections and components, ensuring everything was functioning correctly and safely.
