How often should air ducts be cleaned?

There's no fixed schedule for every home. Most homes benefit every 3–5 years; sooner after renovations, with pets that shed heavily, or if occupants have respiratory sensitivities. Annual filter changes matter more than frequent duct cleaning.

Will duct cleaning lower my energy bills?

Severely restricted ducts force the blower to work harder, so cleaning genuinely clogged ductwork can restore airflow and efficiency. But if your ducts are reasonably clean, the savings are minimal — which is why inspection first matters.

What's the difference between duct cleaning and dryer vent cleaning?

Duct cleaning addresses the HVAC supply and return system; dryer vent cleaning clears the exhaust path from your dryer to the outside — a genuine fire-safety issue when clogged. Many contractors offer both in one visit.

Should I be suspicious of very cheap duct cleaning offers?

Yes. Bait-and-switch duct cleaning is a notorious industry problem: a rock-bottom advertised price balloons on site, or the 'cleaning' is a quick vacuum of vent covers. A legitimate whole-system cleaning takes hours with truck-mounted or high-power portable equipment.

Do you offer free inspections?

Many independent contractors in our network offer free or low-cost duct inspections with camera equipment. Ask when you call.

Direct Answer & Summary

What is Air Duct Cleaning?

Air duct cleaning removes accumulated dust, debris, and contaminants from supply and return ductwork using professional vacuum and agitation equipment. It's most worthwhile after home renovations, in homes with persistent dust despite clean filters, or where airflow seems restricted. A reputable contractor inspects first and shows you what they find — beware anyone who quotes without looking. Call to schedule an inspection.
