AC Repair: Arrived at the client’s home after they reported higher than normal energy bills and decreased cooling performance. Inspected the air conditioning system and found the condenser coil partially blocked and the refrigerant slightly low, causing the system to work harder than normal. Cleaned the condenser coil, checked all electrical connections, and topped off refrigerant to proper levels. Tested the system for correct operation, airflow, and temperature output. The system is now running efficiently, and cooling costs should return to normal.
