"Get recommended by ChatGPT" is now on every HVAC agency's homepage. The real differences are in three places: whether AI search is included or an extra fee, how they measure it, and what happens if it does not move. We checked 9 agencies on their own sites on 29 October 2026. InnoBotZ is one of them.
SHORT ANSWER
The agencies that sell AI search visibility to HVAC companies split into three groups. Included in a flat price: HVAC Foundry and Service Marketing Co at $2,500 a month, month to month, and InnoBotZ at $2,500 (or $1,750 for the first 5) with a day 90 guarantee. Bundled with local SEO: Hook Agency at $3,750 a month with 25+ ChatGPT prompts tracked monthly. Sold separately: WebFX, from $3,000 a month on a 6 month commitment. Scorpion, HVAC Webmasters, Thrive and First Page Sage sell it without a separate published price. Only InnoBotZ publishes a guarantee tied to AI answers.

What does an AI visibility agency actually do?
It works on the things AI assistants read before they name a company: your website pages, your crawler access, your structured data, your Google Business Profile, your reviews, and the directories and best-of lists that mention you. Then it measures whether the assistants name you more often. Google says there are no special requirements for its AI features beyond normal SEO, so the honest agencies sell this alongside SEO, not instead of it. More on the mechanics in AI search visibility for HVAC.

How does each agency measure AI answers?
This is the question to ask, because AI answers change between runs, wordings and assistants. A single screenshot proves very little.
| Agency | What they publish about measurement |
|---|---|
| Hook Agency | 25+ ChatGPT prompts, tracked and reported monthly. |
| WebFX | OmniSEO, tracking visibility across 10+ AI platforms. |
| HVAC Foundry | A monthly AI visibility report; a published study of 66 answers across 12 metros. |
| InnoBotZ | 20 agreed buyer questions, 4 assistants, several runs each, every week; the share of answers naming you is signed on day 0. |
| Others | No measurement method published on the pages we checked. |

An HVAC SEO and GEO practice, month to month. No price on the HVAC page and no named HVAC proof.
One vendor for Google, Maps and AI, or two agencies?
One, if you can. The inputs overlap: the same service page helps your Google ranking and gives the AI something to quote, and the same reviews move your map pins and your AI mentions. Two agencies means two reports, two fees, and nobody who owns the whole answer. If your current SEO agency does not include AI search, ask whether they will measure it. If they will not, that is the gap.
How to choose
- Check yourself first. Ask ChatGPT, Gemini and Perplexity who to call for AC repair in your town, three times each. Count your name.
- Ask how they measure. How many questions, which assistants, how often, and do you get the raw answers?
- Ask if it is included. AI search as a separate fee on top of SEO doubles what you pay for overlapping work.
- Ask what happens at day 90. Nobody can promise a spot in ChatGPT. Somebody can promise what happens if nothing moves.
