Gray Duct Technologies
Gray Duct Technologies is live on Hydra OS — the largest sitemap in this batch at 1,519 pages, led by a title that names the problem before the company: “Dirty Ducts & Unreliable HVAC Fixed.”
Numbers that show up in the bank account.
Gray Duct Technologies presents itself on its live homepage as “Dirty Ducts & Unreliable HVAC Fixed | Twin Cities | Gray Duct,” under the headline “Same-Day Diagnosis & Repair.” The subhead sets the full scope — “Air Duct Cleaning, Dryer Vent Care & Complete Home Comfort” — and the company's own origin line is published on the page: founded by Jason Giandalia, “Gray Duct was created to counter the industry norm of hidden fees and unnecessary upsells.” Its three stated values are Unwavering Integrity, Premium Precision, and Transparent Value.
Verified live: (952) 254-8779 answered around the clock — “24/7 emergency HVAC service, we answer day or night” — a separate text line at (952) 522-6443, over 1,300+ five-star reviews cited on the homepage, two Minnesota addresses (6100 McColl Dr in Savage and 506 Classic Ct in Eagan), an in-house certified team, the Gray Duct Healthy Home Club™ maintenance program, free written estimates, and an upfront diagnosis-and-pricing commitment.
The build is unusual in that duct cleaning and full HVAC carry equal weight. Four core silos — air conditioning, heating, heat pumps, and ductless — are meshed 189 pages deep each, with a 118-page commercial air-conditioning section and a 48-page indoor-air-quality section beside them, and the specialty work (air duct cleaning, dryer vent cleaning, AC coil cleaning, new construction) published as its own service families. A pricing section titled “What it costs in the Twin Cities” and an on-site SEER calculator handle the research stage before a call.
The launch sitemap carries 1,519 URLs: the silos above, 51 service-area pages across Minneapolis, St. Paul, Edina, Eden Prairie, Bloomington, Minnetonka, Lakeville, Maple Grove, Wayzata and the wider metro, a 451-post blog, and a 35-guide Learning Center — the deepest content surface in this launch batch.
The previous public site remains the before capture (archived Jul 4, 2026). Per the publishing rule, after Lighthouse scores, traffic results, and ranking claims stay unpublished until measured on the live Hydra domain.
Every page ships with structured brand intelligence built in, so Google and AI answer engines like ChatGPT, Perplexity, and Gemini can verify exactly what the business does — and new pages are submitted for indexing the moment they go live, not weeks later. It's all built on Hydra OS: a database-free architecture that's dramatically faster and harder to hack than a traditional WordPress site, with an intelligence layer that keeps it optimizing itself.

Production was verified Aug 5, 2026: HTTPS GET followed to the www canonical and returned 200 from CloudFront with Astro assets and no first-party WordPress markup. No platform is named for the before state — the available Wayback snapshot carried no usable platform fingerprint.

More than a website — an operating layer.
A market-specific pricing section that answers the cost question on the page rather than gating it behind a form — the direct expression of the company's transparent-value promise.
An on-site efficiency calculator that lets a homeowner reason about equipment before a technician is involved, feeding the replace-versus-repair decision.
The maintenance program is published as a first-class section with tune-up scheduling, turning a one-off duct cleaning into an ongoing relationship.
A platform that grows with them.
The deepest build in this batch: duct specialty work and full-service HVAC given equal weight across the entire Twin Cities metro.
