What the service assessment can cover
ProTech can assess the reported sequence, controls, airflow, and applicable heating components. Do not bypass safety switches or attempt repeated ignition procedures beyond manufacturer instructions.
Can I diagnose the furnace from an indicator light alone?
An indicator can help identify a condition, but codes are model-specific. Record the exact pattern and equipment information for the technician.
