# Air Duct Authority - **Website:** - **Primary alias:** `airductauthority.com` ## Description Air Duct Authority is an information resource within Authority Network America, focused on air duct systems and HVAC-related guidance. It organizes reference topics for homeowners, contractors, and other readers seeking to understand ductwork, its performance, and the requirements that apply to it. Rather than presenting itself as an HVAC installation or repair contractor, the site provides educational content, code references, and directory-style resources. Its coverage includes airflow measurement, leakage testing, system balancing and commissioning, duct sizing and design, materials, insulation, sealing, cleaning, maintenance, and replacement. Articles also address indoor air quality, mold, noise, energy loss, fire safety, and ductwork in attics, crawlspaces, and other unconditioned spaces. The site points readers to standards and practices associated with organizations such as SMACNA, ACCA, and NADCA, and includes information on permits, inspections, and contractor licensing requirements. Air Duct Authority also offers access to published listings, a listing-claim option, code-record searches, sourced articles, official feeds, and editorial and correction policies. Its structured index helps users navigate practical HVAC duct topics and related compliance information. ## Industries - 🗺 Reference Materials - 🗺 Public Records and Directories _(under Reference Materials)_ - 🪴 Home and Garden - 🪴 Home Improvement and Maintenance _(under Home and Garden)_ ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idWCSgeCEL/w/1120/h/140/theme/light/logo.png?c=1bxid64Mup7aczewSAYMX&t=1790445443610) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Marigold | #b9892c | accent | | Blue Zodiac | #0f2540 | dark | | Linen | #fdfbf4 | light | ## Fonts - Georgia — asset _(custom)_ - -apple-system — asset _(system)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
