Case Study
How a New Domain Landed #1 in Google's AI Overview
Google Search Console, five months from launch. Captured September 13, 2026.
The situation
HVAC/R AI Pro is an AI diagnostic tool for HVAC and refrigeration technicians. Point a phone at an equipment nameplate, get the unit identified, then work the problem with structured troubleshooting guidance, airflow tools, and estimate support.
The product had already been live for months when I came in, but it had no site built around it: no domain history, no links, no authority, no content. I built the content architecture alongside the founder to give an already-working product the search presence it never had.
The competitive picture was not favorable. Search results for every relevant term were held by two groups: Apple and Google Play app listings, and "best HVAC apps" roundups published by field service software companies with dedicated content teams. Established technician apps like Bluon and measureQuick had years of authority and large installed user bases.
A brand new domain does not usually break into that.
What I built
I developed the page architecture and wrote the content for the site's topical cluster, structured as a hub with supporting pages around each of the product's real workflows:
- Troubleshooting (
/hvac-troubleshooting-app), the primary commercial page - Equipment Scanner (
/equipment-scanner), nameplate capture and equipment identification - Airflow and static pressure (
/hvac-airflow-calculator,/airflow-static-pressure-tools) - Duct sizing (
/duct-sizing-calculator,/duct-sizing-ductulator-app) - Refrigeration (
/refrigeration-tools) - Estimates (
/hvac-estimate-app) - Web dashboard (
/hvac-web-dashboard) - Features overview (
/features)
Each page was mapped to a specific query cluster before it was written, with internal linking designed so the pages reinforce each other instead of competing.
The editorial rule I set was that the pages had to be honest about what the product does not do. The Equipment Scanner page states plainly where nameplate capture fails: faded plates, bad angles, partial reads. Technicians are a skeptical audience who catch overstatement immediately, and pages that acknowledge limits earn more trust than pages that don't.
The blog: field guides that feed the pillar pages
Once the pillar pages were live, I built out a blog of field guides under the same architecture: each post answers one specific diagnostic question a technician would actually type into Google, then links back into the pillar page that covers the broader workflow. The blog doesn't compete with the cluster for rankings, it feeds it, adding the long-tail, question-shaped queries that AI Overviews and featured snippets pull from most often.
- Why is my AC not cooling but the fan is running? — supports Troubleshooting and Refrigeration tools
- Why is my AC freezing up? — supports Troubleshooting and Refrigeration tools
- What should static pressure be in HVAC systems? — supports Airflow and static pressure
- What causes high static pressure in HVAC systems? — supports Airflow and static pressure
- How to measure airflow in HVAC systems — supports Airflow and static pressure
- How to troubleshoot low airflow in HVAC systems — supports Troubleshooting and Airflow and static pressure
- How to size ductwork correctly — supports Duct sizing
- Why is my furnace blowing cold air? — supports Troubleshooting
- How to estimate HVAC jobs in the field — supports Estimates
Every post follows the same editorial rule as the pillar pages: work the diagnostic logic a technician would actually use in the field, then connect it to a specific tool rather than a generic pitch.
Results
All figures are from the client's Google Search Console property, captured September 13, 2026. Nothing is estimated or drawn from third-party tools.
Five months from launch

Page-one placement on the head term
/hvac-troubleshooting-app now holds page one for "hvac troubleshooting app." In a signed-out, neutral US search it appears sixth organically, above measureQuick's App Store listing and above ServiceTitan's "14 Best HVAC Apps" roundup.
That improvement was recorded on September 8, 2026, before the optimization work described below. I include it because it is in the data, not because I am claiming it.
The strongest query on the site
"hvac ai app" holds average position 5.1 with an 8% click-through rate, the best-converting term the site ranks for.
Named first in Google's AI Overview
For "hvac ai app," Google's AI Overview opens by defining HVAC/R AI Pro, cites hvacrai.com as a source, and lists the product first under "Top HVAC AI Apps and Tools," ahead of BuildOps and Bluon.
This matters more than a blue link. AI Overviews and AI-mode answers are where a growing share of this audience will look, and being the cited source rather than a competitor's mention is the difference between being the answer and being absent from it.
