ChatGPT Ads for HVAC companies.

The diagnostic question is the opportunity

Almost nobody asks an assistant for an HVAC contractor. They ask why their air conditioner is blowing warm air, what a refrigerant leak smells like, whether a fifteen-year-old unit is worth repairing, and what a replacement should cost.

That diagnostic conversation is where the job is decided. By the time someone searches for a contractor they have usually already concluded what they need, and often what they are willing to pay. Being present during the diagnosis is earlier and more valuable than being present during the search.

The buying model suits it. You describe the conversations where your business belongs in plain language rather than assembling a keyword list, which rewards knowing what your customers describe rather than what they type.

Licence details are not optional here either

Businesses offering licensed services may be required to prove they hold the necessary credentials, which for an HVAC contractor means having the documentation ready before you apply rather than after.

The Australian requirement is separate and stricter. Federal law makes the refrigerant handling authorisation number a mandatory element of HVAC advertising. That obligation attaches to the advertising, not to the platform, so a ChatGPT campaign promoting services carries it exactly as a Google campaign does.

Breaching that condition is a strict liability criminal offence rather than a paperwork matter. Texas has its own HVAC advertising rule with a broad definition of what counts as an advertisement. Neither of those changes because the surface is conversational.

Seasonality works differently on a conversational surface

On Google, the first heatwave produces a spike in searches and a corresponding spike in click costs as every competitor turns their campaigns on at once.

The conversational surface is less crowded, at least for now, precisely because almost no local businesses are using it. That is the argument for testing it during a demand spike rather than in the quiet months, which is the reverse of the advice we would give you for organic work.

It is also the argument for testing it now rather than in two years. The advantage of an immature channel is that it is cheap while nobody else has noticed.

What we could not verify, and why that matters

OpenAI's own ad policies page returns a 403 to our tooling, so the eligibility position comes from secondary reporting and is dated accordingly. The policy has changed four times in five months.

The Australian authorisation requirement is not in that category. It comes from the regulation itself and it has not moved. Whatever the platform permits, the licence details belong in advertising that promotes your services.

What we do on an HVAC ChatGPT Ads account

• An eligibility and market check before you spend anything
• Licence and refrigerant authorisation details placed correctly before the campaign runs
• Documentation prepared in case enhanced verification is required
• Context descriptions built from the diagnostic questions customers actually ask
• Repair and installation treated as separate propositions, because they convert differently
• A small first budget timed to a demand period rather than a quiet one
• Monthly reporting on clicks, cost and booked jobs, with the policy re-checked each time
