01Duct cleaning
Some of these are good reasons to clean the ducts. Others usually point somewhere else.
Sanding drywall, cutting and demolition put fine dust into the air, and a running system pulls much of it into the returns. Cleaning the ducts, the blower and the coil afterward keeps that dust from being blown back into the rooms.
Droppings, nesting material or a dead animal in a duct is a real reason for cleaning. The affected runs are cleaned, and the gap that let the animals in is found and closed, or they come back.
Growth on the inside of metal ducts, on the coil or in the blower means moisture is reaching the system. Cleaning removes it, but it returns unless the moisture source, often a leak, a drain problem or condensation, is fixed as well.
When visible dust or debris puffs out of the supply vents as the system starts, the ducts or the blower hold more than normal. A camera run inside the ducts shows how much and where before any cleaning is done.
Most household dust starts in the rooms or comes in from outside, and dust stuck to duct walls tends to stay put. A better-fitting filter and a sealed return often do more than cleaning, so the ducts are worth looking at before deciding.
02Worth it or not
The reason for cleaning matters more than how long it has been.
After a renovation left fine dust in the system, when rodents or insects have been living in the ducts, when growth is visible inside metal ducts or on the equipment, or when debris actually blows out of the vents. Each is something specific that cleaning removes.
As a routine on a fixed calendar, because the house seems dusty, or when the only evidence is a grey film on the vent covers. Dust clinging to duct walls mostly stays there, and a filter that fits properly does more for the air in the rooms.

03A proper cleaning
A proper cleaning treats the ducts and the equipment as one system, because dirt left in one part spreads to the rest.
The system is put under strong suction, usually from a large vacuum collector connected to the ducts, so loosened dust is pulled out rather than into the rooms. Brushes or compressed-air tools then work through each run to break the debris free. Any access openings cut for the work are sealed closed again at the end.
Cleaning only the duct runs leaves the job half done. The grilles, the blower, the indoor coil and its drain pan collect dirt too, and whatever stays in them spreads back through the clean ducts. Where growth was the reason for the work, the moisture that fed it has to be tracked down and fixed, or the growth comes back.
04What changes the job
Rigid sheet metal stands up to brushes and suction. Flexible duct and duct board are easier to damage, so they are cleaned more gently, and a badly soiled run of either may not be worth cleaning at all.
Cleaning works through the vents and a few access openings, so the number of runs, their length and the turns they take decide how much of the system can actually be reached.
Fine construction dust, nests, droppings and growth each call for different handling. Pest debris and growth also mean finding how the animals or the moisture got in, which is a separate repair from the cleaning.
05Questions
There is no set schedule that suits every building. Ducts are worth cleaning when there is a reason, such as renovation dust, pests, growth or heavy debris, and otherwise can go many years without it. Changing the filter on time does more to keep them clean than any routine cleaning.
Not by itself, in most cases. A dusty duct wall does little to the air moving past it. Dirt on the indoor coil and the blower wheel does restrict airflow, which is why a proper cleaning includes those parts, and why they matter more than the ducts.
Sheet-metal ducts clean well. Flexible duct and duct board are more easily damaged by brushes and agitation, and runs of either that are badly soiled, wet or grown over are often replaced rather than cleaned.
What the system is doing, when it started, what the thermostat is set to and what it reads, and whether the outdoor unit is running. The age of the equipment and a photo of its label help a technician arrive prepared.
