Access zone
The provider should state how much clear space is needed around registers, returns, the thermostat, and air handler. Do not move heavy items without a safe plan.

Containment should protect occupied rooms
Review access zone, then connect the observation to its source, system location, and a written scope.
DIRECT ANSWER
Start with the condition, not the sales package
Duct cleaning brings hoses, tools, and access work into occupied spaces. EPA says carpet and household furnishings should be protected. A preparation plan should also address pets, children, fragile items, electronic equipment, floor finishes, and the path between the equipment and each register.
Home protection is not a promise that no dust will ever appear. It is a written set of controls: covers, drop cloths, corner guards, sealed collection, careful register removal, cleanup, and a walkthrough. Ask who moves furniture and who is responsible for existing damage documentation.

What deserves a closer look
Occupant plan
Pets and children should stay away from hoses, open registers, tools, and chemicals. Discuss noise and any temporary system shutdown.
Finish protection
Wood, tile, carpet, painted grilles, and walls need material-appropriate protection. Photograph delicate areas before work.
