The Atlanta board, explained

How many HVAC companies in Atlanta show up in ChatGPT's answers?

17, out of the 56 we verified — 30% of the Atlanta cohort. Everyone else went unmentioned across all 4 of our July 2026 checks.

Who does ChatGPT name first in Atlanta?

Estes Services leads the July 2026 edition, surfacing in every one of the 4 checks. Reliable Heating & Air, Plumbing and Electrical - Kennesaw follows. Positions are set by measured naming frequency alone.

How was the Atlanta list generated?

4 checks built this list, using phrasings like "Which company should I use to replace my air conditioner in Atlanta, Georgia?". Every company ChatGPT named got counted; nothing else influenced the board.

Can HVAC companies buy their way onto this list?

They can't. Measured, never sold is the standing rule: being named by ChatGPT in our checks is the only path onto the board. Money cannot buy a place on this list.

Why isn't my company on the Atlanta list?

It means ChatGPT never named it in our July 2026 checks — nothing more. That says nothing about the quality of the work, only that homeowners who ask AI are being sent elsewhere. Most companies haven't shown up in AI answers yet.
