What assistants named this edition
Probe battery input, never a score. The same questions, the same edition, who was named.
Named by a subset of assistants. Only ChatGPT and Perplexity name them this edition; Gemini never does. If either changes its mind, the other still names them — or does not. That is an input on the receipt, not a score.

Q: Which HVAC companies in Evanston do people trust most?
For Evanston, Illinois, the strongest local-trust candidates appear to be Flader Plumbing & Heating, Deljo Heating & Cooling, and Hero Air—but "most trusted" depends on whether you prioritize a truly local shop, volume of reviews, or emergency availability.

Q: Are the big HVAC chains in Evanston better than independent shops?
Some well-known Evanston-area providers marketed as larger firms include Four Seasons, Deljo, Hero Air, and other companies serving the broader Chicago/North Shore area. A local industry listing gives those firms strong reported ratings and availability, but because that information is promotional, treat it as a starting point—not proof that one is best for your house.
