Which Fort Worth air conditioning and heating companies do ChatGPT, Gemini and Perplexity recommend?

By Lance Rankin, MBA | Tested November 10, 2026.

The short answer: three AI assistants, one question, three different lists. Together they named 18 air conditioning and heating companies. Only 3 were named by two assistants. None were named by all three.

The question we asked

"Who are the best air conditioning and heating companies in Fort Worth, Texas?"

We asked it once in each assistant, with web search turned on, the way a homeowner would.

Companies are listed in the order each assistant gave them.

Named by more than one assistant

  • Prime Time Heating and Air Conditioning: ChatGPT and Perplexity
  • Lawrence Air Conditioning & Heating: ChatGPT and Perplexity
  • Fort Worth Air Conditioning Co.: Gemini and Perplexity

The other 15 companies were each named by only one assistant.

Where each assistant got its list

The assistants do not pick from memory. They search, read a few pages, and repeat what those pages say.

  • ChatGPT cited three ranking sites: DFW Professionals, ContractorsRanked and Industry Oversight. In its answer it also pointed to ConsumerAffairs, Expertise.com and Angi reviews.
  • Gemini linked to the Diamond Certified directory for Tarrant County for two of its picks, and to the companies' own websites for the other four. Two of those were pages written just for Fort Worth.
  • Perplexity cited ten list and directory pages, including ConsumerAffairs, BestProsInTown, CityVetted, DFW Professionals, Yahoo Local and Forbes Home.

What this means if you own an air conditioning company

  1. The two companies ChatGPT and Perplexity agreed on both sit at the top of review-ranking sites with hundreds of five-star Google reviews. Review count is doing a lot of the work.
  2. Gemini leaned on a certification directory and on company websites. A clear page on your own site for the city you serve gives it something to quote.
  3. Perplexity repeated the list sites. Being on several of them is how a company gets named.
  4. A customer who asks ChatGPT and a customer who asks Gemini are being sent to completely different companies. You need to check all three.

How we ran this test

  • One question, asked once in each assistant, on November 10, 2026.
  • ChatGPT (GPT-5.4), Gemini (Flash) and Perplexity (Sonar Pro), each with live web search on.
  • AI answers change. Ask the same question tomorrow and some names will be different. This is one snapshot, not a ranking.
  • This is a report of what the assistants said. It is not Digital Regiment's opinion of any company, and nobody paid to be on this page.
