DECISION ORDER

Investigate, measure, then buy.

A high score does not predict a specific dollar loss. It identifies unresolved conditions that can inflate bills or reduce comfort and should be tested before equipment sizing.

  • Ask for measured duct leakage and airflow where relevant.
  • Inspect attic air paths before adding insulation.
  • Use actual annual bills, not one peak month.
  • Require Manual J before final replacement sizing.
