On Monday morning, I began by conducting a thorough inspection of the HVAC system to identify any issues. I meticulously checked the thermostat, air filters, and ductwork for any signs of wear or blockages. After identifying a faulty thermostat, I replaced it with a new one, ensuring it was properly calibrated for optimal performance. I also cleaned the air filters and ducts to enhance airflow and efficiency. Additionally, I performed a comprehensive check on the plumbing system, ensuring all pipes were free of leaks and functioning correctly. The job concluded with a detailed review of the system's performance and a final walkthrough to confirm everything was operating smoothly.
