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.
