Superior HVAC Service did a thorough seasonal maintenance tune-up that brought our aging system back to peak performance. The technician chemically cleaned the heavily fouled outdoor condenser coils, checked the compressor amp draw against factory specs, and provided a comprehensive digital health report of our system.

The AC was running constantly but the house wasn't cooling. the technician found restricted airflow from a collapsed duct section combined with a low refrigerant charge. He fixed both issues in one visit and explained everything clearly.
