Homeowners who ask Gemini or Perplexity "who can fix my AC near me" get an answer built from different sources than a traditional Google search. Gemini leans heavily on Google Business Profile data and local map signals, while Perplexity crawls the web in real time and cites specific pages it finds credible. If your HVAC business has consistent, detailed information in both places, you show up in the answer instead of losing the customer to a competitor who does.
How Gemini ties into Google Business data
Gemini, Google's AI assistant, pulls heavily from the same data pool that powers Google Maps and Google Business Profile listings. When a homeowner asks Gemini for an AC repair company nearby, it draws on your business name, hours, service area, review content, and categories the way local search results always have. An incomplete or outdated Business Profile means Gemini has less accurate material to work with, so it may skip your company for one with fuller information.
This matters because Gemini does not treat your website as the primary source the way a classic search engine might. It treats your Business Profile as the anchor and your website as supporting detail. Photos of completed jobs, specific services listed (like "ductless mini-split repair" or "emergency AC service"), and recent reviews mentioning those services all feed into how confidently Gemini can describe what you do. A profile that only says "HVAC contractor" with no other detail gives Gemini little to work with when a homeowner asks a specific question, like whether you handle a particular brand or system type.
How Perplexity cites sources and what that means for you
Perplexity works differently from Gemini because it functions as an answer engine that crawls websites directly and shows its sources as clickable citations. When someone asks Perplexity which AC repair companies serve their area, it is not just checking a business directory. It is reading web pages, comparing what they say, and quoting or linking to the ones that answer the question clearly and specifically.
This means the content on your website carries more direct weight with Perplexity than it does with Gemini. A page that clearly states your service area, the systems and brands you repair, your response times for emergency calls, and pricing structure gives Perplexity something concrete to cite. Vague marketing language like "quality service you can trust" gives it nothing to quote, so it moves on to a competitor's page that states specifics. Perplexity also tends to favor pages that read like direct answers to questions homeowners actually ask, rather than pages written purely to describe a company in general terms.
Differences a homeowner sees across engines
A homeowner researching AC repair sees noticeably different results depending on which AI tool they use, because each engine sources and formats answers differently. Gemini tends to surface a short list of nearby businesses with map-style details, similar to a local search result. Perplexity tends to produce a written answer with named companies and linked citations to the pages it pulled from, which can include review sites, your website, or local directories.
Google AI Overviews, which appear directly inside standard Google search results, blend both approaches: they often summarize information similar to what Gemini uses, but with citation links similar to Perplexity's format. ChatGPT, when connected to browsing, behaves more like Perplexity in that it looks for pages with clear, specific answers rather than relying only on a business directory. For an HVAC owner, this means one gap, like missing service details on your website, can hurt your visibility on Perplexity and ChatGPT while a thin Google Business Profile hurts you on Gemini and AI Overviews. Both need attention, not just one.
What to publish so all three can quote you
Getting quoted across Gemini, Perplexity, and other AI tools comes down to publishing specific, structured information in both your Google Business Profile and your website content, since each engine draws from different combinations of the two. The goal is to remove ambiguity so an AI tool has a direct, quotable answer instead of having to guess or skip your business entirely.
Start with your Google Business Profile: list every service you actually perform, not just "HVAC repair," and keep hours, service area, and photos current. On your website, publish clear service pages that state what systems and brands you work on, whether you offer emergency or same-day service, and what your process looks like when a customer calls. Answer the specific questions homeowners ask before they call, such as how quickly you respond to a no-cooling call in summer or whether you service a particular brand of unit. Pages written as direct answers to real questions are what Perplexity and ChatGPT tend to pull from, and consistent, detailed business information is what Gemini and AI Overviews rely on. Covering both gives every engine a reason to mention your business by name.
The myth that's costing HVAC owners visibility
The most common misconception among AC repair owners is that AI search tools like Gemini and Perplexity work the same way as a Google search always has, so nothing about their marketing needs to change. The reality is that these tools decide which businesses to mention based on how clearly a business describes its specific services and location, whether on its website or its Business Profile, and a generic listing that once ranked fine in traditional search can be passed over entirely when an AI engine is choosing who to name in a spoken or written answer. Treating AI visibility as a separate, ongoing part of how customers find your business, rather than an automatic byproduct of showing up in search results, is what actually keeps your company in the conversation.
