Free Air Duct Cleaning and Inspection Offers: What You Actually Get

A free inspection is often a real service. A free or $99 whole-house cleaning usually isn't the whole house. The difference sits in the scope, and the scope is the one thing most flyers leave off.

Quick answer

Free air duct inspections are common and often genuine, since companies use them to quote the real job. Free or $99 whole-house cleanings usually cover only part of the system. NADCA warns that low-cost specials often skip the air handler, blower, coils, registers or access openings. Ask for the scope and total price in writing; around Dulles a full cleaning runs about $500 to $800 per system.

What Low-Price Specials Leave Out

NADCA's homeowner guide warns about extremely low-cost whole-house specials. They often cover only part of the system and exclude the air handler, blower fans, coils, registers or the access openings a proper cleaning needs. The add-ons arrive once the crew is in the house, often with a mold scare or a sanitizing pitch. NADCA also says no product disinfects ductwork 100 percent.

The pattern matches the warning signs in the duct cleaning scams guide.

How to Compare a Free Offer With a Real Quote

  1. Ask What "Whole House" Means

    Get the number of supplies and returns the price covers.

  2. Ask About the Equipment

    The blower, coil and drain pan should appear by name.

  3. Ask for the Total in Writing

    The EPA advises a written agreement with the total cost and scope.

  4. Price It Against the Market

    The air duct cleaning cost guide lists what full jobs cost around Dulles.

When a Free Offer Is a Good Deal

A free camera inspection that ends with photos and a written quote is a fair offer. It shows you the inside of your own ducts and lets you decide. A camera inspection near Dulles costs $0 to $125 when it isn't free, and many companies waive it when you book the cleaning.
