Summary
We scanned the 50 most-reviewed HVAC companies in Denver, Colorado across three major AI models: ChatGPT, Gemini, and Claude.
Home services is an incredibly competitive market, heavily reliant on local visibility and reviews. But as homeowners increasingly turn to AI for contractor recommendations, our findings reveal that the traditional metrics of trust—five-star reviews—do not guarantee AI visibility.
Specifically, 88% of the top 50 Denver HVAC contractors simply disappear when AI is asked for recommendations. Even massive local operations generating thousands of positive reviews find themselves completely omitted from the "Top Of Mind" results of modern AI search.

This report relies on systematic AI querying conducted in March 2026.
- Sample: 50 top-reviewed HVAC companies operating in Denver, Colorado
- Algorithms tested: ChatGPT, Gemini, and Claude
- Query Design: natural homeowner prompts ranging from broad recommendations ("best HVAC companies") to specific needs ("furnace repaired")
- Scoring Mechanism: Each firm received a visibility grade (0-100) based on mention consistency, answer positioning, and cross-model alignment
Sample Questions We Asked AI
“Can you recommend the best HVAC companies in or near Denver, Colorado? Who are the top providers in this area and what makes them stand out? Please include company names and websites.”
“I need my furnace repaired in Denver, Colorado. Which HVAC companies should I consider? I want to compare pricing, reviews, and services.”
“Who are the best heating and cooling companies serving the greater Denver area? I want to see all the top options across the metro. Please include company names and websites.”
Each prompt was submitted as a cold inquiry (fresh chat session) to prevent context contamination.
Overall Visibility Findings
The "Local Authority" Gap
In local SEO, reviews are currency. In AI visibility, they are just a piece of the puzzle. There is a significant gap between the companies that dominate Google Maps and the companies that AI prefers.
Denver's second most-reviewed HVAC contractor, Tipping Hat Plumbing, Heating & Electric, holds an impressive 6,843 reviews at 4.7 stars. Despite this overwhelming local authority, they scored a flat 0/100 and were completely invisible across all three models in our tests. Similarly, Mighty Plumbing Heating Air and Electric (4,017 reviews) and Doctor Fix-It (3,920 reviews) also failed to generate a single AI mention.
However, Applewood Plumbing Heating & Electric (16,758 reviews) managed to bridge the gap, securing the top spot with a score of 53/100.

Model Disagreement
The models exhibit a 100% disagreement rate when recommending Denver HVAC companies. Unlike in other verticals we tested, Gemini finally participated, naming specific local practices rather than simply directing users to Google Search.

Top Overall Competitors by AI Mention Volume
AI’s Narrow Lens
There are roughly 450 independent HVAC and heating contractors serving the Denver metro. But AI only knows about 42 (9%) of them.
If your home services company isn't in that 9%, you aren't an option for modern homeowners using AI as their primary search engine.
What This Means for Denver Trades
- The funnel is shifting. Potential customers who would normally hunt through Yelp or Google Local are bypassing them to ask ChatGPT.
- Reviews ≠ Visibility. Sitting comfortably with 4,000 positive reviews is no longer a protective moat against AI discovery.
- The space is highly concentrated. Franchise names steal organic mindshare. Competing requires knowing where you stand first.
