Conducted a thorough spring maintenance check on the air conditioning system, ensuring it was in optimal condition for the upcoming cooling season. This included a comprehensive inspection of the entire HVAC system, cleaning and replacing air filters, lubricating moving parts, and checking refrigerant levels. I also examined and cleaned the condensate drain lines to prevent clogs and leaks. Additionally, I tested the thermostat functionality, adjusted settings for energy efficiency, and inspected electrical connections for safety and reliability. The system was thoroughly cleaned, and any necessary adjustments were made to ensure peak performance. The customer was provided with a detailed maintenance report and tips for maintaining the system throughout the year.
