How to show up in ChatGPT, Perplexity and Google AI answers as an air duct cleaning company
What the AI answer engines read when someone asks for a trustworthy duct cleaner, the signals they weigh, and the plain-text changes to your site and profile that get you named.
Type "is air duct cleaning a scam" into ChatGPT and you get a careful answer about the EPA's position, the $49 bait-and-switch pattern, and advice to look for a company that uses negative air equipment, shows before-and-after results and quotes a full price up front. Then type "who should I call for duct cleaning in [your town]" and the engine names two or three companies. Whether yours is one of them comes down to what the engines can read about you, in plain words, on pages they can reach.
This guide covers what they read, what they weigh, and the changes that get a duct cleaner named. None of it requires new software.
What the answer engines actually read
The AI answer products do not have a private directory of duct cleaners. They lean on web search results, your Google Business Profile, review text, and any page that states facts about your company in clear sentences. Perplexity and ChatGPT with browsing cite the pages they used. Google's AI Overviews and AI Mode draw on the same index as regular search, with heavy weight on the Business Profile for local queries.
That means the inputs are the ones you already have, in a different order of importance:
- Your website, specifically pages with sentences a machine can quote: what you do, how, where, for how much.
- Your Google profile, especially categories, services with prices, and the Q&A section.
- Review text that mentions specific services, prices and towns.
- Mentions on other local sites: chamber listings, local news, neighborhood groups, HVAC partner sites.
35.1% of duct cleaners have no website and 31.6% have not even listed hours. The engines have nothing to say about those companies, so they say nothing.
Write the sentences you want quoted
The single change that moves the needle most is a page on your site that states the facts in plain declarative sentences. Not "we are your trusted partner for indoor air quality." Sentences like these:
- "[Company] cleans residential air ducts in [town], [town] and [town] using a truck-mounted negative air vacuum with rotary brush agitation."
- "A whole-house cleaning for a single-system home of about 2,000 square feet costs between $375 and $550 and takes two to four hours."
- "Dryer vent cleaning is $100 to $175 and includes a lint check at the exterior hood."
- "The price quoted on the phone is the price on the invoice. There are no per-vent add-ons."
- "[Company] is a NADCA member" if you are, with the certification number.
Put these on your home page or a dedicated "How our duct cleaning works" page. Add an FAQ section with the questions homeowners ask the engines: how much does it cost, how long does it take, how often should ducts be cleaned, do you use chemicals, is it a scam. Answer each in two to four sentences. That is the text that gets lifted into an AI answer with your name attached.
Make the trust signals machine-readable
The engines are tuned to be skeptical in this category because the scam question is asked constantly. They look for the markers the EPA and consumer sites say to look for. Make yours explicit:
- State your equipment by type. "Truck-mounted" or "portable HEPA negative air" in words, with a photo captioned the same way.
- State your process steps as a numbered list: inspect, seal registers, connect negative air, agitate each run, clean the air handler, show before-and-after.
- State your license and insurance, and the NADCA membership if you have it, on the page and in the footer.
- Put your price range in text, not in an image.
- Mark up the page with LocalBusiness schema that includes your service area, phone and hours. If your site builder supports FAQ schema, use it on the FAQ section.
Fix the profile fields the engines pull
Google's AI features draw heavily on the Business Profile for "near me" style questions. Three fields matter most:
Services with prices. Each service listed with a range gives the engine a fact to repeat. The profile guide covers the full list.
Q&A. The engines read it. Seed six questions and answer them in your own words.
Review text. You cannot write reviews, but you can ask for specifics. A review that says "cleaned both systems in our 2004 house for $600, showed us the camera footage" gives the engine a service, a price and a proof point. The reviews guide has the ask that produces that kind of text.
Get mentioned where the engines look
Local citations have mattered for years and matter more now because the engines treat a company that appears in several places as more likely to be real. Priorities for a duct cleaner:
- A listing on your HVAC partners' sites as their referred duct cleaner, with a link.
- The local chamber of commerce and any home builder or realtor association you can join.
- A NADCA directory entry if you are a member.
- One local news or neighborhood site mention. A short piece on dryer vent fire safety before the holidays, offered to a local outlet, is the easiest to land in this trade.
- Consistent name, address and phone everywhere. Variations confuse both Google and the engines.
Check your visibility monthly
Ask ChatGPT, Perplexity, and Google's AI Mode the same five questions once a month and keep the answers in a spreadsheet: "best air duct cleaning in [town]," "honest duct cleaning company near [town]," "how much does duct cleaning cost in [town]," "dryer vent cleaning [town]," and "is [your company] legit." Note which companies get named and which pages get cited. Then read the cited pages and see what they say that yours does not. This takes 20 minutes and is more useful than any rank tracker.
Frequently asked
Do I need to block or allow AI crawlers? Allow them. Blocking GPTBot or PerplexityBot in robots.txt removes you from the answers. The traffic is small; the mentions are worth it.
Does any of this help regular Google rankings too? Yes. Plain declarative pages, a complete profile, specific reviews and local mentions are the same signals regular local search uses. There is no separate AI SEO; there is just doing it clearly.
How long before an engine names us? Perplexity and ChatGPT pick up new pages within days of indexing. Google's AI features take longer and track your map pack position closely. Expect two to three months for a company starting from a thin profile.
AI search optimization is one of the services in the free 14-day trial. We write the pages and the profile text and check the engines monthly. Text or call (385) 486-5536.
