Which HVAC companies does AI recommend in Phoenix?
We asked ChatGPT, Google Gemini, and Perplexity to recommend HVAC companies in Phoenix, AZ — 6 hiring questions, 18 recorded answers, every one saved. They named 54 different businesses. These are the 18 that came up more than once.
Ideal Air Conditioning and Insulation appeared most often, in 7 of 18 answers. 17 other businesses also appeared more than once.
Definition: openness measures how spread out the business names were in these 18 answers. Higher means more dispersed; lower means more concentrated. It is not market saturation, demand, or a quality score.
The 18 HVAC companies that came up more than once.
Ordered by how many of the 18 answers named them. This is not a ranking of quality and none of these are our clients — it is a record of who three assistants named for Phoenix, AZ on July 26, 2026. If you are one of the HVAC companies in this market and you are not on this list, the scan did not observe your business among the repeat names.

Even Ideal Air Conditioning and Insulation does not win everything here. It was never named when we asked about 24-hour emergency service. Those question types returned different names in our sample.
All three assistants agreed on 2 of them
Ideal Air Conditioning and Insulation, Parker & Sons were named by ChatGPT, Gemini, and Perplexity alike. Agreement across three systems that read different sources is a stronger observed pattern than appearing in only one system. In Phoenix, that happened for 2 businesses.
57.1% of Phoenix homes are owned by the person replacing the system.
A system swap is an owner's capital decision, and owners hold 57.1% of Phoenix's 601,397 occupied homes, with a median home value of $381,900 and a median build year of 1984. Census counts 1,604 plumbing, heating, and air-conditioning contractors with payroll in Maricopa County — the two trades share one code — one per 1,154 county housing units. Out of that combined field, the assistants named 54 HVAC-specific businesses for Phoenix.
City figures: American Community Survey 2019-2023 5-year estimates, Phoenix city, Arizona. County figures: County Business Patterns 2023, Maricopa County; establishment counts include only businesses with paid employees. The two boundaries are different sizes and are never divided into each other.
In Phoenix, the evidence sits on goettl.com.
This is a record of observed answers, not a paid ranking. In Phoenix they read goettl.com and consumeraffairs.com when forming their answers. The industry page explains how we address website and third-party evidence: what we build for hvac companies.

The assistants disagreed on 5 of 6 questions
Asked the identical question about Phoenix, 5 of 6 comparisons produced no shared business at all — three assistants, three separate shortlists. There is no single "AI answer" for this market to optimize against, which is why being named by one assistant tells a Phoenix owner very little about the other two.
5.6% of answers named nobody at all
In 1 of 18 answers the assistant declined to recommend anyone and pointed the buyer at a directory or a list of things to check instead. Those are answers where no Phoenix business won anything.

Method. 6 questions × 3 assistants = 18 answers for Phoenix, AZ alone, collected July 26, 2026 from ChatGPT (gpt-5-mini), Google Gemini (gemini-flash-latest), Perplexity (sonar), with web search enabled because that is what a buyer's app does. Names were resolved across spelling variants first, so one company spelled three ways counts once. Assistants are non-deterministic; this is one dated run, not a standing ranking.
