Why I'm building an AI Front Desk for the trades

Every family-owned HVAC company in America is losing jobs the same way. The owner is under a furnace. The phone rings. Voicemail picks up. The customer — whose air conditioning just died in a Texas summer — taps the next result on Google. That's a $300 repair or a $7,000 replacement, gone in the time it took to check a voicemail.

I've been in living rooms watching this happen. Not because the owners are lazy or bad at their jobs — they're some of the hardest-working people I know. The trades run on physical presence: someone has to be at the customer's house, hands on the equipment. When the phone rings while they're on a job, there's no one to answer.

Why generic chatbots don't solve this

The obvious response is: "just add a chatbot." And plenty of HVAC companies have tried. The problem is that generic chatbots — the same ones built for SaaS companies and e-commerce stores — know nothing about HVAC. Ask their bot "there's a strong gas smell in my basement" and it'll happily offer you a Wednesday morning appointment.

That's not a small mistake. Gas leaks kill people. The right answer is "leave the house, call 911, then call the gas company" — and only after the customer is safe does anyone talk about scheduling.

This is the pattern across the trades: certain calls are true emergencies (no heat in January, burning smell from an outlet, active water leak) and the bot has to know the difference. Not from a rulebook a customer support engineer wrote at 3am. From a system built around the specific realities of the vertical.

The wedge: vertical intelligence

I'm building Zyntralink as an AI Front Desk for local service businesses — but with vertical-specific intelligence built in. HVAC is vertical one. It's live now. It knows:

Plumbing is next. Then electrical. Then roofing. Same engine, different domain knowledge per vertical. If the sales cycles teach me something surprising, I'll reorder.

Where I am today

HVAC is live at hvac.zyntralink.ai/embed/demo. I'm talking to family-owned HVAC companies in DFW right now. The first three get 60 days free as design partners in exchange for feedback and a testimonial.

I'll write here as I learn what works, what breaks, and what surprises me. If you want to follow along, check back or email me. If you're an HVAC owner in DFW — or you know one who's tired of voicemail — that same email address is where to send them.
