DIRECT ANSWER
Start with the condition, not the sales package
EPA says a thorough visual inspection is the best way to verify cleanliness. The final check should cover the components in the agreement and the condition of the home, not only a single dramatic before-and-after image. Ask to see representative return and supply interiors, plenums, blower area, coil faces when included, drain pan, registers, filters, and access closures.
Cleanliness is not the only result. Fiberglass should remain intact, coil fins should not be crushed, registers should be secure, access doors should be airtight, rooms should be clean, and the system should operate normally. Record any item that needs correction before final acceptance.
