The Contractor’s Guide to AI Search
How HVAC, Plumbing & Roofing Companies Get Found by ChatGPT, Gemini & Perplexity
By Aaron Husak · April 2026 · 20 min read
I spent 20 years running an HVAC and plumbing company. Now I run Sequoia GEO, and I’m watching the biggest shift in local search since Google Maps changed everything for contractors. This guide covers what’s happening, why it matters to your business right now, and the exact steps to make sure AI recommends you instead of your competitors.
Why I Wrote This Guide
I spent 20 years running an HVAC and plumbing company. I scaled it to 130+ employees and landed on the Inc. 5000 four years in a row. Now I run Sequoia GEO, and I’m watching the biggest shift in search since Google Maps changed everything for local businesses.
Here’s what’s happening:
900M
ChatGPT weekly active users
Processing 2+ billion queries per day
800%
Perplexity year-over-year growth
45 million active users and climbing
60%
of U.S. searches show AI Overviews
Google Gemini above your organic listing
25%
predicted drop in traditional search
Gartner forecast by end of 2026
When a homeowner asks ChatGPT “who is the best HVAC company in Phoenix?” or tells Perplexity “I need an emergency plumber in Dallas,” your business either shows up in that answer or it doesn’t. And right now, most contractors are invisible to AI search.
I wrote this guide because nobody in our industry is talking about this honestly. The marketing agencies selling you SEO packages haven’t adjusted their playbook. Your competitors don’t even know this shift is happening yet. And that gap is the single biggest marketing opportunity I’ve seen since I started my first company.
What Is GEO (Generative Engine Optimization)?
SEO — Search Engine Optimization — is about ranking on Google’s list. When a homeowner searches “AC repair near me,” SEO determines whether your company appears in the results.
GEO — Generative Engine Optimization — is about being the answer that AI gives. When that same homeowner skips Google entirely and asks ChatGPT, “Who should I call for AC repair in Fresno?” GEO determines whether the AI recommends your company by name.
With SEO, you’re competing for a spot on a list the homeowner scrolls through. With GEO, you’re competing to be the recommendation. There’s no list to scroll. There’s no second page. The AI either mentions you or it doesn’t.
The AI Search Platforms That Matter Right Now
ChatGPT — 900 million weekly users, processing 2+ billion queries per day. The largest AI platform and growing fast. When people say “I asked AI,” they usually mean ChatGPT.
Google AI Overviews (Gemini) — Google’s own AI-generated answers that appear at the top of search results. These now appear in up to 60% of U.S. searches. Your potential customers see this before they see your website listing.
Perplexity — An AI-native search engine processing 1.2–1.5 billion queries per month. It cites its sources, which means if your business is mentioned, users can click through to your website. Growing 800% year-over-year.
Microsoft Copilot — Built into Windows, Microsoft Edge, and Bing. Every Windows user has access to this.
What Actually Happens When Someone Asks AI for a Contractor
A homeowner’s water heater breaks at 9 PM. Ten years ago, they’d grab the Yellow Pages. Five years ago, they’d search Google for “emergency plumber near me.” Today, an increasing number of them open ChatGPT on their phone and type: “My water heater is leaking. Who should I call in [city]?”
ChatGPT responds with specific company recommendations by name — not a list of ten links. If your company wasn’t mentioned, you didn’t just miss a ranking position. You were completely invisible in that interaction.
Why Contractors Cannot Ignore This
I heard the same thing about Google Maps in 2010. “People will always use the Yellow Pages.” The contractors who moved first on Google Maps dominated their local markets for the next decade. The ones who waited are still trying to catch up.
The numbers:
- Gartner predicts traditional search volume will drop 25% by the end of 2026
- ChatGPT’s weekly users doubled in one year — from 400 million to 900 million
- Perplexity grew 800% year-over-year
- Google AI Overviews now appear in up to 60% of searches — and when they do, organic click-through rates drop by 61%
- 71% of Americans already use AI-powered search tools to research purchases or evaluate brands
The Zero-Click Problem
When AI gives an answer, many users never click through to a website at all. They get the recommendation, call the number, and move on. Seer Interactive’s research found that organic CTR dropped 61% for queries where AI Overviews appeared.
The Flip Side
35% more organic clicks
for sites cited as sources within AI answers. Being the AI’s answer is the new pole position.
The First-Mover Window
Right now, most of your competitors don’t even know GEO exists. In my experience scaling a contracting company, the contractors who moved first on every platform change — Google My Business, Local Service Ads, review platforms — captured market share that took their competitors years to claw back. The same window is open right now with AI search, and I estimate it’s a 12 to 18 month window before the industry catches up.
How AI Search Decides Who to Recommend
When ChatGPT or Perplexity receives a query like “best HVAC company in Dallas,” here’s what the AI evaluates:
1. Your Online Footprint Across Multiple Sources
AI models don’t just look at your website. They pull from every source they were trained on and can access in real-time:
- Your website content
- Google Business Profile (the single most important structured data source for local AI recommendations)
- Review platforms
- Industry directories and associations
- News mentions
- Social media presence
- Citation consistency across the web
2. Authority Signals
AI is looking for signals that your business is legitimate, established, and trustworthy: review volume and sentiment, consistent business information (NAP), topical authority on your website, and backlinks from credible sources.
3. Content That Answers Real Questions
Your website might have a page that says “We offer AC repair services” — but that doesn’t help AI answer the question “How much does AC repair cost in Phoenix?” or “What are the signs my AC needs to be replaced?” AI evaluates whether your content actually answers the questions homeowners are asking.
4. E-E-A-T: Experience, Expertise, Authoritativeness, Trustworthiness
Google introduced these quality guidelines for traditional search, but they’re even more important for AI recommendations. When I ran my contracting company, the things that made us successful — earning thousands of five-star reviews, maintaining BBB accreditation, getting mentioned in trade publications, keeping our website updated with real job photos and detailed service descriptions — are exactly the signals that AI now uses to decide who to recommend.
The 7-Step GEO Playbook for Contractors
Audit Your Current AI Visibility
Before you change anything, find out where you stand. This takes 15 minutes.
Open ChatGPT, Perplexity, and Google (look for the AI Overview section at the top of results). Search for these phrases, replacing [city] with your primary service area:
- “Best [HVAC/plumber/roofer] in [city]”
- “Who should I call for [AC repair/water heater/roof leak] in [city]?”
- “[Your company name] reviews”
- “Emergency [plumber/HVAC] [city]”
- “How much does [AC repair/water heater replacement] cost in [city]?”
Document what you find. Are you mentioned? Are your competitors? This baseline is critical — you can’t improve what you don’t measure.
Claim and Optimize Every Directory Listing
AI models pull data from directories and citation sources. If your business information is incomplete, inconsistent, or missing from key platforms, you’re invisible to AI.
Priority platforms: Google Business Profile (#1 by a wide margin), Yelp, Angi/HomeAdvisor, Better Business Bureau, industry associations (ACCA, PHCC, NARI), local Chamber of Commerce, and social media.
The key requirement: consistency. Your business name, address, phone number, and service area must be identical across every platform.
Build Topical Authority on Your Website
For each service you offer, your website should include: what the service involves, common problems and solutions, cost information with ranges and factors, FAQ sections with real homeowner questions, and service area-specific pages.
If your website has five pages, AI has almost nothing to work with. Contractors getting recommended by AI have 20, 30, 50+ pages of relevant content. The depth and specificity of your content is what signals topical authority to both AI models and traditional search engines.
Generate and Respond to Reviews at Scale
Review volume and sentiment are among the strongest signals AI uses. For AI specifically:
- Volume matters — 500 reviews beats 50 at the same star rating
- Recency matters — consistent 2026 reviews outperform a burst from 2022
- Sentiment keywords matter — reviewers mentioning specific services helps AI match you to relevant queries
- Responses matter — replying to every review signals an active, engaged business
Get Mentioned in Authoritative Sources
Ways to earn authoritative mentions: trade publications, local media, industry events, awards programs (Inc. 5000, Best of [City]), and manufacturer partnerships (Trane, Carrier, Rheem dealer locators).
Every third-party mention of your business is a data point that makes AI more confident recommending you. The more credible the source, the stronger the signal. When I was running my company, landing on the Inc. 5000 list generated more inbound mentions than almost any other marketing activity we did. That credibility compounds over time.
Create FAQ-Rich Content
Create FAQ pages or blog posts that answer questions like:
- “How much does a new AC unit cost in [city]?”
- “What are the signs I need a new water heater?”
- “How often should I have my furnace inspected?”
- “What should I look for when hiring a plumber/HVAC tech/roofer?”
Structure these with the question as an H2 or H3 heading, followed by a thorough 100–200 word answer. This format is what AI models extract most efficiently. It also tends to perform well in traditional search, which means this investment works on two fronts simultaneously.
Monitor and Measure Your AI Visibility
Monthly monitoring checklist:
- Search your business name and top services in ChatGPT, Perplexity, and Google AI Overviews
- Document whether you’re recommended, cited, or absent
- Note which competitors appear
- Track referral traffic from AI platforms in Google Analytics (chat.openai.com, perplexity.ai)
- Monitor review velocity
- Check citation accuracy quarterly
GEO + SEO: Why You Need Both
GEO does not replace SEO. Traditional Google search still drives the majority of local service leads.
SEO captures the people searching Google today. GEO captures the people asking AI tomorrow. And they reinforce each other.
Strong SEO improves GEO visibility, and GEO-optimized content tends to rank better in traditional search. The keyword research, content development, and citation building that powers one also powers the other. They’re complementary, not competing.
Budget Recommendation
If you’re currently spending $5,000/month on SEO and PPC, allocate 20% toward GEO-specific optimization. This includes content development, citation management, review generation systems, and AI visibility monitoring.
For contractors with service pages already built out for HVAC, plumbing, and roofing, the GEO layer builds directly on that foundation. You’re not starting over — you’re extending what you already have.
Common Mistakes Contractors Make With AI Search
“AI Search Will Pass — I’ll Wait”
This is the same thing contractors said about Google Maps in 2010. Waiting is not a strategy. The platforms are growing too fast, the homeowner behavior shift is already underway, and the first-mover window is measured in months, not years.
Thinking Traditional SEO Is Enough
Good SEO helps your GEO visibility, but it’s not sufficient. They overlap but aren’t the same thing. SEO focuses on matching keywords and earning backlinks. GEO requires structured data, conversational content formats, consistent citations across every platform, and the kind of topical depth that signals genuine expertise.
Having a Thin Website
If your website has five pages, AI has almost nothing to work with. Contractors getting recommended by AI have 20, 30, 50+ pages of relevant content. Every page that answers a real homeowner question is a signal that your business has depth and credibility.
Ignoring Reviews or Not Responding
Every review is a data point AI processes. Not generating new reviews means your data is going stale. Not responding to reviews signals a business that doesn’t engage with its customers — which AI interprets as a credibility risk.
Using a Template Website That Looks Like Everyone Else
When AI evaluates multiple contractors and three of them have nearly identical website content, it has no basis to differentiate or recommend one over another. Original, specific content about your company — your actual service area, your team, your process, your real job photos — is what gives AI a reason to recommend you over the next guy.
What To Do Right Now
The contractors who moved first on Google Maps dominated their markets for a decade. The same window is open right now with AI search.
Start with the audit in Step 1. It costs you 15 minutes and gives you an honest picture of where you stand. Most contractors who do it are surprised by what they find — either completely absent from AI results, or appearing in ways they never intentionally set up. Either way, knowing is the starting point.
If you want a professional audit that covers all four major AI platforms and gives you a prioritized action list, that’s what we do at Sequoia GEO. No pitch, no obligation. Just a clear picture of where you are and what to do about it.
