Cleaning that's warranted by what's actually in the ducts, not by how many months have passed since the last one.
Air duct cleaning physically removes dust, construction debris, insulation fragments, rodent nesting material or other material actually sitting inside the duct system. That is what the work is and what it accomplishes — it does not treat allergies, it does not lower an energy bill by some fixed number, and it does not disinfect a house. Anyone selling it as a health fix is selling more than the work can deliver.
The honest cases for cleaning are specific: dust after a remodel or new construction, a rodent problem that got into the ducts, visible debris you can see at a register or return, or water that reached a duct run. Outside those situations, most homes do not need it on a fixed interval, and a contractor should be willing to look, or ask the right questions over the phone, before recommending a full-house cleaning.
Describe the problem and we'll tell you whether it's cleaning, sealing, repair, or not a duct problem at all.
