Here's what's bleeding

Four leaks every HVAC shop has — most don't measure any of them.

  • Missed Calls During Business Hours

    20–35% of inbound calls to home-service businesses go unanswered. At a $400–$700 average ticket, every missed call that would have closed is direct revenue your competitor catches.

  • After-Hours Emergencies

    31% of HVAC inbound calls happen after hours. Emergency tickets run $600 to $1,200. Your $400/mo answering service still misses one in three — and the customer doesn't wait. They call the next guy.

  • Stale Leads That Die In Your Pipeline

    ServiceTitan flags it. Housecall Pro flags it. Nobody calls. The customer wasn't ready that day. Two weeks later they called the shop that did follow up. You never knew.

  • Revenue Leak

    Most HVAC shops doing residential service lose $5,000–$15,000 a month to the three leaks above. Combined. Some lose more. Almost none measure it.

Voicemail is the most expensive employee you've never fired.

Voicemail alone costs you $350 to $1,200 every job it misses.

When a homeowner is facing an emergency, they don't leave a voicemail and wait to hear back. They call the guy who's going to answer and come out as soon as possible.

The fix isn't another answering service. It's a fine-tuned employee that follows your protocols, understands your workload, knows your customers, and gives you the peace of mind that while you're on the job, it's handling the booking, escalations, and quotes for you. And it tells you about every call it took.

How it works

From first call to live system.

  1. Step 01

    The call

    We talk for 30 minutes. All free. I get an understanding of how your shop runs, what's working, what's not, and see if we're a good fit.

  2. Step 02

    The audit

    I provide a breakdown of your existing setup. It shows where you're losing money. And what to do about it.

  3. Step 03

    The build

    Setup is $2,800 to $7,200 (based on complexity). Live in 2 weeks. If the system doesn't catch 95% of your missed calls in 30 days, I refund every dollar — and you keep the working system on your accounts.

  4. Step 04

    The tune-up

    I continue to fine-tune, make corrections, integrate with more of your existing tools, and add new tools when you need them. $700 to $1,200 a month. No contract.

Why this works

Built like an employee. Not a chatbot.

The best HVAC call is answered by a trained receptionist who knows your shop, knows your customers, and books the job fast. People respond best to that. They want their AC working. They want to feel cared for — not handled like a ticket number.

The system replicates that experience. You write the protocols, the same way you'd onboard a new hire: what to ask, what to say, when to book, when to escalate, when to hold the line on an emergency. Every script approved by you before it ever takes a call.

Then it connects to your stack. Your dispatch system. Your CRM. Your scheduling tool. When a returning customer calls, it already knows them — name, address, last service date, open work order. Trust gets built from the integration up, not faked in conversation.

It improves with every call. Conversations are encrypted, logged, and yours to review. You get the recording, the transcript, the metric — real data, not vendor-side estimates. And when a call needs a human, it routes to you, your on-call tech, or your dispatcher. The AI's job is to handle what it should and hand off what it shouldn't.

Every advantage to help the customer fast. Because that's what they actually need.

Frequently Asked Questions

"AI sounds like a robot — won't my customers hate it?"

The system doesn't sound like AI. It sounds like a polite, attentive office that responds at 2am. You approve every script before it goes live. You hear samples first. If a customer ever sounds frustrated, you get a notification and can take the conversation over personally.

"I've been burned by automation vendors before. Why is this different?"

You own what I build. The system runs on your phone number, your CRM, your accounts. If you fire me tomorrow, you keep the system; nothing locks. We're not an agency and not a SaaS — I'm an engineer building infrastructure on your side of the wall. The 30-day money-back pilot is the proof.

"I already have an answering service. It's crappy but cheap."

Your wife, dispatcher, or answering service doesn't lose anything — they manage the system instead of fielding "is this the right number" calls. Techs see only qualified, scheduled jobs. The capacity overflow is part of the audit. Customer data stays in your existing systems; we don't store it externally.

"How will I know if this actually worked?"

The 30-day metrics report tells you the number of missed calls intercepted, the number converted to scheduled jobs, and the dollar value recovered. If those numbers don't justify the spend, the setup fee gets refunded. After-hours SMS is configurable — quiet hours, urgency thresholds, escalation rules. You decide.

"I'm 60. I don't want to learn new software."

You don't learn anything. You give me access, approve scripts, and check in twice over 30 days. ~110 minutes total. The system works on top of what you already have. Your team's day-to-day doesn't change — just fewer "we missed your call" apology calls.
