How often should ducts actually be cleaned?

There is no fixed interval that applies to every home, and any company quoting one is selling a schedule rather than answering the question. Clean when there is a reason: a renovation, visible discharge from registers, evidence of pests, or a new occupant with allergies and no history on the system. For many homes that means every five to seven years, and for some it means never.

Will duct cleaning lower my energy bills?

Only marginally in most cases, and any company promising large savings is overselling. Duct cleaning removes debris. Duct sealing addresses air leakage, and that is where the meaningful energy savings actually sit. If lower bills are your goal, sealing is the better place to spend.

How long does it take?

Three to five hours for a typical Springfield home. Anyone in and out in forty-five minutes has not cleaned the full system, whatever the invoice says.

Air Duct Cleaning in Springfield, IL

Air duct cleaning in the Springfield area typically costs $450 to $900 for a whole system, meaning every supply run, every return and the main trunk lines. Be cautious of advertised prices under $150, which almost always cover a small number of vents and function as a route to an upsell once the crew is inside.

Done properly, duct cleaning uses a negative pressure vacuum connected to the main trunk while each individual run is agitated with a brush or compressed air whip, so dislodged debris travels to the collection unit rather than into the house. A shop vac at each register is not the same job and does not produce the same result.

The honest position on who benefits: households after a renovation, homes with visible dust discharge from registers, systems where rodent or insect activity has been found, homes where someone has significant dust allergies, and houses being taken over from previous owners with unknown history. For a well-sealed, regularly filtered system with no specific complaint, the case is much weaker, and we say so rather than selling it on a schedule. Our honest look at duct cleaning claims covers that in detail.

If the inspection turns up disconnected runs or leaking joints, cleaning alone will not fix the underlying performance issue. See ductwork repair and replacement. Dryer ducts are a separate job with a separate safety rationale, covered under dryer vent cleaning.
