Air Quality & Duct

The air quality & duct cluster: air-duct-cleaning cost from a base fee and the number of vents, dryer-vent-cleaning cost with a rooftop/long-run surcharge, air-scrubber / negative-air CFM sizing from the room volume and an ACH target (required CFM = ACH × volume ÷ 60), and indoor-air-quality post-remediation cost with clearance testing. Sizing values are labeled IICRC/AHAM typicals a certified technician confirms on site.

Planning estimate: this is a planning estimate from the numbers you enter — not a bid, a contract or an insurance valuation. Restoration pricing depends on category/class, materials, access and local labor. Get itemized written quotes from licensed, insured, IICRC-certified restoration contractors before you commit.
Planning typicals: equipment counts are planning typicals from IICRC/AHAM rules of thumb. Actual counts depend on the class of water, materials and airflow on site — a certified technician must confirm the drying/containment plan.

Every Air Quality & Duct tool is calculated server-side — visible immediately — with its formula, a worked example and a reference table, and works on the quantities you measure and the prices you enter from your own quotes. Background reading is in the guides.
