Are some registers weak or run times long?
For a property in Norfolk, furnace and air-conditioning cleaning should be scoped around the actual equipment, not just the registers. Record the make and model if visible, note weak airflow or long run times, and photograph accessible areas around the furnace cabinet and condensate drain. Ask whether the proposed work includes individual blower blades, the evaporator coil, and the drain path, and how electrical controls will be protected. Cleaning is distinct from diagnosing or repairing a mechanical fault.
