Artificial intelligence is rapidly becoming the new starting line for homeowners researching a major project. Asking an AI for a list of top-rated local roofers or plumbers seems like a powerful shortcut, but relying on its neatly packaged summaries alone can be a costly mistake. While AI can be a helpful research assistant, it suffers from critical flaws that can render its recommendations for local businesses incomplete or, in some cases, entirely false.
The convenience of AI is undeniable, but its conclusions about a contractor's reputation must be treated with skepticism. The technology's two main blind spots—data access limitations and a tendency to fabricate information—mean that the glowing (or damning) summary you receive might not reflect reality. For homeowners, this creates a clear imperative: use AI to discover options, but use original sources to make decisions.
AI's Blind Spots: Walled Gardens and Hallucinations
Before you trust an AI’s recommendation, it’s crucial to understand how it can get things wrong. The first major issue is that AI search tools often cannot access all the information you might expect. According to research from BrightLocal, prominent AI models like ChatGPT cannot see inside what it calls Google’s "walled garden of reviews." This means if a contractor’s reputation exists primarily on their Google Business Profile, an AI might be effectively blind to it, presenting a skewed or incomplete picture of their track record.
The second, more alarming problem is a phenomenon known as “hallucination.” In simple terms, this means the AI presents an answer that sounds plausible but is, in fact, "false, inaccurate, or completely made up," as described by SoFlo Impact Windows, a company that has studied the issue. An AI can fabricate details about a business, including negative reviews or customer complaints that do not exist. This can unfairly damage a company's reputation and mislead a homeowner before they have a chance to review the actual evidence from real customers.
Why Verification Is a Non-Negotiable Step
Given these limitations, treating an AI summary as the final word on a contractor is a significant risk. A company’s reputation is built over years of real-world performance, communication, and customer service—factors that can be misrepresented by a flawed algorithm. When an AI invents a negative review, it creates a false impression that could cause you to dismiss a great contractor or, conversely, overlook red flags it failed to find.
Many consumers already understand this need for due diligence. A BrightLocal survey found that 42% of consumers always check reviews on the original platforms to verify AI recommendations. They want to see the original context and confirm that the AI’s summary matches the truth. This behavior highlights a best practice for anyone making a significant hiring decision. Visiting review sites allows you to see not just the star rating but also how a business responds to feedback, and whether customers have uploaded photos of the completed work—details that build confidence at the crucial decision stage.
