I was called out for a one-time HVAC cleaning to address reduced airflow and improve overall system efficiency. I began by removing buildup from the blower wheel and evaporator coil, then flushed the condensate drain to prevent clogs and potential water damage. I also cleaned the condenser unit outside and checked the ductwork for any visible dust or blockage. After replacing the air filter and testing the system, everything is running clean, smooth, and ready to deliver reliable cooling.
