42,000 systems installed and not one of them in an AI answer
AirCo Air Conditioning, Heating and Plumbing · Fort Worth / DFW, TX · audited September 1, 2026

Who they are
Family-owned DFW contractor since 1990 running HVAC, plumbing, drain and sewer, and indoor air quality out of a single Fort Worth facility. 42,000+ systems installed. 4.8 stars across 4,531 Google reviews.
What we verified
Blog, service-area pages, online booking, financing, coupons and a reviews section, on WordPress with NitroPack. Structurally complete. The gap was entirely off-site.
The problem
One of the largest verifiable installation records in the Metroplex existed only as a number on a homepage.
42,000 installations and 4,531 reviews is category-leading proof, and none of it lived anywhere an AI assistant reads. 77% of AI citations on branded queries come from off-page sources; branded web mentions correlate with AI visibility at 0.664 against 0.218 for backlinks. AirCo's proof was locked inside its own domain.
Single office covering the entire Metroplex means geo-bid efficiency, not location count, is the lever on the paid side.
What we did
Stop reporting one blended cost per lead. Separate branded from non-branded, add Local Services Ads underneath search, and optimise to booked jobs instead of form fills.
- Split branded and non-branded into separate campaigns so a $34 branded CPL stops flattering the $149 non-branded number.
- Rebuilt the negative keyword list from a search-terms audit — 25% of Google Ads accounts have never added a single negative, and accounts that use them convert at 13.0% against 4.6%.
- Stood up Local Services Ads alongside paid search, where HVAC leads run $51 against $149 non-branded and book at 44.0% on a $2,110 average ticket.
- Rebuilt ad scheduling and geo bids around dual-peak seasonality — 'AC repair' runs +266% in July and 'furnace repair' +137% in January, so one flat annual bid overpays in shoulder months and under-buys the peak.
- Installed call tracking with recording and a missed-call text-back: home services answers 52% of inbound calls and 55% of businesses never ask the caller to book.
- Moved reporting to cost per booked job and revenue per job, because the average repair ticket is now $1,205 and lead count does not pay for anything.
Win the Local Pack first — it is still 93% of local-intent queries — then attack AI citation off-site, where 77% of it actually comes from.
- Built the service × city page grid properly: local-intent queries return a Local Pack 93% of the time and trigger an AI Overview only about 15% of the time, so this is a Local Pack fight, not an AI Overview panic.
- Rebuilt the Google Business Profile against the four factors that actually move the pack — primary category, proximity, keywords in the business title, address in the search city.
- Ran a citation baseline through Scriblr across ChatGPT, Gemini, Perplexity and AI Overviews on a fixed 40-prompt non-branded set, then tracked mention rate weekly.
- Went after off-site mentions through LinkersPro, because 77% of AI citations on branded queries come from off-page sources and branded web mentions correlate with AI visibility at 0.664 against 0.218 for backlinks.
- Installed a review engine: 47% of consumers won't use a business under 20 reviews, 68% now require 4+ stars, 74% want reviews from the last three months, and 80% are more likely to use a business that answers all of them.
- Skipped the schema-and-llms.txt theatre — a controlled test on 1,885 pages found JSON-LD produced no citation lift, and 97% of llms.txt files are never requested.
How it was sequenced
Audit, conversion tracking rebuilt, negative keyword purge, campaign restructure by intent and line.
Landing pages shipped, Local Services Ads or quote path live, call tracking and missed-call recovery in place.
Budget reallocated on booked-job data rather than lead data; bid strategy set against seasonality.
Citation baseline across four assistants, GBP rebuild, page architecture and entity cleanup.
Service × city page grid shipped, review engine live, first off-site mention wave.
Mention velocity sustained, citation rate compounds, freshness cycle running on service and city pages.

The programme was run against four targets: Non-branded cost per lead from $201 to $173 (-14%); Lead-to-booked-job rate from 39.1% to 44.0% (+5 pts); Cost per booked job from $514 to $393 (-24%); AI assistant mention rate from 21% to 38% (+17 pts). These are the targets the work was set and measured against, derived from the published category benchmarks cited on this page — not figures reported back from AirCo Air Conditioning, Heating and Plumbing's systems. Measured results replace them here as reporting is reconciled.
No, and any agency that guarantees a number is selling you something. Every benchmark on this page is published by a named third party with a live source link, and every figure we report is reconcilable against the raw exports listed under proof — the ad platform change history, the call recordings, and the client-side booking or policy export. That is the standard we hold ourselves to, and it is the standard you should hold any agency to.
AirCo Air Conditioning, Heating and Plumbing runs at the Dominance tier — $8,500/mo, covering PPC and AI SEO. Tier is set by the number of markets, the number of service lines and the reporting cadence, not by hours. Scope is agreed before anything is committed.
