I performed a preventative maintenance service on the HVAC system to keep it running efficiently and extend its lifespan. I inspected all critical components, including the compressor, contactor, capacitor, and blower motor, ensuring everything was operating within proper parameters. I cleaned the condenser coil, flushed the drain line, and tightened all electrical connections. I also checked refrigerant levels and tested the thermostat for accurate temperature control. With everything tuned and running smoothly, the system is ready for reliable performance through the season.
