The clearest signs are dust that settles back within a day or two of cleaning, a puff of dust from the registers when the system starts, and grey fuzz or debris you can see behind a register. Your Neighbor's Air Care films the inside of the ducts before any cleaning, so you can see for yourself.

These are the signs that most often turn out to be dirty ducts when Your Neighbor's Air Care puts a camera inside:
Some situations put dust into the ducts whether you see it or not:
The U.S. EPA lists ducts infested with rodents or insects, and ducts clogged with excessive amounts of dust and debris or releasing particles from the supply registers, among the conditions in which cleaning should be considered.
Some problems look like dirty ducts but have other causes. A room that gets weak airflow may have a crushed or disconnected duct rather than a dirty one. Dust on a register cover alone can simply be room dust. A high energy bill or a system that runs constantly points to the equipment, which Your Neighbor's Air Care does not service. That is why Your Neighbor's Air Care looks inside before quoting a cleaning rather than selling one on a symptom.
Turn the system off, lift a floor register or unscrew a wall register, and shine a phone torch into the boot behind it and as far down the duct as you can see. A thin film of dust is normal. A thick grey layer, clumps of hair, construction debris or anything that looks like droppings is a reason to call. Do the same at a return grille, which is usually the dirtiest opening in the house. Take a photo and send it to Your Neighbor's Air Care by WhatsApp: it often answers the question before anyone drives out.
With a camera. Before any cleaning, Your Neighbor's Air Care films the inside of the ducts and shows you the footage. If the ducts are dirty, the full air duct cleaning follows: every supply and return run brushed under a negative-air machine, the registers washed, and the same runs filmed again at the end. If they are clean, you are told so and nothing is charged for a cleaning you did not need. The air duct camera inspection can be booked on its own, and dusty registers alone are covered by air vent and register cleaning.

Dust back within a day or two of cleaning, dust puffing from the registers, grey fuzz on the vents or debris behind a register are the clearest signs. Your Neighbor's Air Care films the ducts first so you can see.
Dirty ducts can blow their build-up back into the rooms every time the system runs, and that is often what a household notices first. Your Neighbor's Air Care shows the footage, so you see whether the ducts are the cause.
Not always. A crushed, kinked or disconnected duct gives the same symptom. The camera look shows which it is.
Yes. A photo of the inside of a register boot or a return grille, sent to Your Neighbor's Air Care by WhatsApp, often answers the question and starts the free quote.
