Your HVAC Competitors Are Getting Picked by AI — Here’s Why You’re Not
We audited 176 HVAC profiles across 9 SGV cities using Google's Maps-grounded AI. Only 50 got surfaced. The gap between those 50 and the rest came down to one number: review count.
Your phone rings differently in 2026. A homeowner’s AC dies at 9pm. They don’t open Google and scroll ten blue links. They ask Google’s AI “best HVAC contractor near me,” and take whoever comes back first.
You are either in that answer or you are not. There is no page two.
We ran an audit of 176 HVAC contractor profiles across nine cities in the San Gabriel Valley and Southeast LA — Montebello, Monterey Park, Pico Rivera, Commerce, Bell Gardens, East Los Angeles, Rosemead, Alhambra, and Whittier — using Google’s Maps-grounded AI (Gemini with Google Maps grounding). We wanted to know exactly which profiles it surfaces and which ones it skips. Here’s what we found.
What the numbers actually look like
Across all nine cities, Google’s Maps-grounded AI surfaced 50 of 176 profiles. That’s roughly 1 in 3.5. The split by city:
- Bell Gardens: 8 surfaced out of 16 audited — the highest rate in the cohort
- Pico Rivera: 7 of 20
- Alhambra: 7 of 20
- Whittier: 6 of 20
- Montebello: 5 of 20
- East Los Angeles: 5 of 20
- Rosemead: 5 of 20
- Monterey Park: 4 of 20
- Commerce: 3 of 20 — the lowest rate
Commerce is brutal. Three profiles out of twenty made it into the AI answer. If you’re an HVAC contractor based in Commerce, you have a 15% shot at being named — before any other variable is considered.
The one number that separated the winners from everyone else
We looked at two things the agencies always argue about: how recent your newest review is (review velocity) and how many reviews you have total.
Review velocity was a wash. The median newest-review age for surfaced profiles: 41 days. For skipped profiles: also 41 days. Having a fresh review did not move the needle.
Review count was a different story entirely.
Surfaced profiles had a median of 82 reviews. Skipped profiles had a median of 10.
That’s not a small gap. That’s an 8x difference. Google’s AI is not impressed by your most recent five-star review. It’s looking at whether your profile has enough accumulated signal to be worth recommending at all.
Profile A — a typical surfaced contractor in our audit, based in Whittier — had 605 reviews and a newest review 41 days ago. Profile B — typical of the skipped group, based in Montebello — had 3 reviews and a newest review 59 days ago. Only one gets named when someone asks Google’s AI for help at 9pm.
Why ratings barely mattered (and this should scare you)
Of the 176 profiles in our cohort, 151 had a rating of 4.8 or higher. Only 8 were in the 4.5–4.7 range. Only 7 were below 4.5.
Nearly every HVAC contractor in these nine cities has a great rating. Which means your 4.9 stars is not a differentiator — it’s the table stakes everyone else already has. The AI is not breaking ties on stars. It’s breaking ties on volume.
How Google's AI actually picks who to name
When someone asks Google’s AI “best HVAC contractor near Alhambra,” it isn’t crawling your website for keywords. It’s pulling from your Google Business Profile — the same profile you may have set up three years ago and haven’t touched since.
The AI reads your profile the way a structured database query works. It checks: Does this business serve this area? Do they have enough reviews to be credible? Is the information consistent and complete?
That last part is where most contractors quietly fail. Your service area on your GBP says “Los Angeles County” because that’s what someone typed in when they set it up. Your website says you serve Alhambra, San Gabriel, Temple City, and Arcadia. Your Yelp listing has a different phone number. ChatGPT or Google’s AI reads all of that and sees noise, not a clear signal.
Independent traffic data backs up what we saw in the audit. Brands that get surfaced consistently — the ones Similarweb found received 2.5x more site visits when recommended by AI — have one thing in common beyond review count: their information is the same everywhere the AI might look.
What "consistent and accessible" actually means for your business
This is not about technical SEO tricks. It’s about operational alignment — your business information matching reality across every platform that feeds AI systems.
Your Google Business Profile: This is the primary source. Make sure your service area cities are listed explicitly — not just “Los Angeles County.” If you serve Alhambra, Rosemead, Monterey Park, and Whittier, those cities need to be named. Your business hours need to be current. Your phone number needs to match your website.
Your website: The cities you serve should appear on your site in plain text, not buried in a JavaScript map widget that AI systems can’t read. A simple service area page — “We serve Alhambra, San Gabriel, Temple City, Arcadia, and surrounding communities” — does more for your AI visibility than a blog post about “5 Signs Your AC Needs Servicing.”
Third-party directories: Yelp, Angi, Thumbtack, Nextdoor, the Better Business Bureau. The phone number, address, and business name on all of them should be identical to your GBP. One stale listing with an old phone number creates a conflict the AI resolves by picking someone else.
Your reviews: You already know you need more. The audit made that obvious. But the ask matters. “Leave us a review on Google” is weaker than texting a customer a direct link to your review page thirty minutes after the job is done. Most contractors who get to 80+ reviews didn’t get there by accident — they systematized the ask. They sent a direct link the same day the job closed. That’s the whole system.
The Monday morning version
You don’t need to overhaul everything at once. Here’s where to start:
1. Check your GBP service area right now. Log into your Google Business Profile, go to “Service area,” and make sure the specific cities you actually serve are listed by name. If you see only a county or a radius, fix it today.
2. Match your phone number everywhere. Google your business name. Click through to Yelp, Angi, and any other directory that shows up. If the phone number is different anywhere, update it. This takes 20 minutes.
3. Count your Google reviews. If you’re under 50, that’s your biggest problem. Build a simple follow-up text — sent the same day a job closes — with a direct link to your Google review page. Send it from your personal number the first few times until it becomes habit.
4. Add a plain-text service area to your website. One paragraph, real city names, no JavaScript map. Something like: “We provide HVAC service to homeowners and businesses in Alhambra, Rosemead, Monterey Park, San Gabriel, Temple City, and surrounding communities.” That’s it.
The contractors showing up in AI answers aren’t doing anything exotic. They have more reviews than you, their information is consistent, and their service area is clear. Those are fixable problems — but only if you start fixing them.
