Your HVAC operation should run even when you're not watching it.
Linchpin Systems builds custom automation systems exclusively for residential HVAC businesses - so no lead goes cold, no review goes uncollected, no estimate goes unfollowed, and no maintenance contract lapses while you're running your operation.
The problem isn't your service. It’s every opportunity that falls through the cracks while you’re delivering it.
The 2 PM Attic Crisis
You're under a unit in a customer's attic at 2 PM on a Tuesday in July. Your phone rings. You can't answer. The homeowner has a broken air conditioner and it's 95 degrees outside. They hang up without leaving a message and immediately call the next contractor on their Google search results.
That scenario plays out dozens of times a month for the typical HVAC business. Meanwhile, a customer from last week hasn't left a Google review. An estimate you sent went unanswered. A maintenance contract is due for renewal and no one has followed up. None of this is happening because you don't care - it's happening because you're running a business and there aren't enough hours in the day.
The Linchpin Solution
Linchpin catches the lead before they go cold. When a call is missed, the system sends an automatic text-back in under 60 seconds, logs the lead in your FSM, and alerts your team. From there, it keeps the follow-up moving by chasing unsold estimates, collecting Google reviews, and handling the small touches that usually get buried when you’re running calls, crews, and customers all day.
13 automation systems built exclusively for residential HVAC businesses. One connected operation.
Linchpin Systems builds custom automations that run in the background of your HVAC business, handling the follow-up, logging, reminders, and outreach your team doesn’t have time to chase.
Built from scratch for your operation. Connected to your FSM platform (Jobber, HouseCall Pro, ServiceTitan, Google Sheets, etc..), your Email Platform (Outlook, Gmail, etc..), and more. No off-the-shelf software. No shared platform. Built on top of what you already do, running for you and maintained for you.

Lead Response Automation

Lead Response Automation
When a call to your business goes unanswered, the system automatically sends a personalized text-back in under 60 seconds, logs the lead in your CRM or FSM, and alerts your team with the caller’s details. The lead gets a response before they call the next HVAC company on Google.
Review Collection Automation
expand_more
When a job is marked complete in your FSM, the system waits 2–4 hours and sends the customer an SMS with a direct Google review link. If no review comes in, it follows up by email after 48 hours. This helps compound your Google Business Profile ranking over time without your team having to remember every ask.
Unsold Estimate Follow-Up
expand_more
When an estimate hasn’t converted into a booked job within 5–7 days, the system automatically triggers an SMS and email follow-up sequence. It helps recover revenue from diagnostic time you already invested instead of letting good estimates die in the inbox.
From first conversation to fully automated operation.
Consultation
We schedule a call or exchange a few emails. You tell me about your operation and how you currently handle the problems we solve. I ask questions until I know exactly which system(s) will provide maximum value. You can start with one or multiple. If we’re in agreement, we move to the next step.
Agreement
A straightforward service agreement is sent the same day or next. Once signed and the deposit is received, the build begins. You fill out an intake form and authorize access to your tools. No ambiguity on scope, timeline, or cost.
Custom Build
Every automation is built from scratch for your specific operation and connected to the tools you already use - Jobber, HouseCall Pro, ServiceTitan, and more. Everything is tested end-to-end internally before you ever see it.
Go-Live
I walk you through what was built and confirm everything fires correctly. Documentation is handed over. We go live. The remaining 50% of the setup fee is due at go-live. From that point forward it runs automatically - no staff involvement, nothing falling through the cracks.
Ongoing Support
Monthly monitoring, adjustments, and support are included in the retainer. If something stops working, I fix it. If your business evolves, the system evolves with it.
Watch the Lead Response Automation fire in real time.
This is a demonstration recorded live by Kyler, the Founder - not a mockup. A real missed call triggers the full system: automated text fires to the lead, the CRM entry appears in Jobber, and the owner receives a notification - all within a few seconds. Although this is just one of the systems we offer, this one was chosen as the primary demonstration.
⚠️ Demo uses Jobber only as an example. Leads will be automatically logged to ANY FSM platform that you use - Housecall Pro, ServiceTitan, Google Sheets, or whatever you already run. Nothing required on your end.

Built by someone who respects what you’ve built.
My name is Kyler Quirk. I’m the founder of Linchpin Systems. I’m a Veteran, Louisiana born and raised, and a proud American.
I built this company because I kept seeing the same problem - good HVAC operators running excellent businesses and losing revenue not because of bad service, but because no one was there to follow up. The missed call at 2pm. The estimate that never got a response. The maintenance customer who renewed with someone else because nobody reached out first.
That's not a people problem. It's a systems problem. And it has a fix.
I built Linchpin Systems specifically for HVAC because I respect what owner-operators have built - the trucks, the reputation, the years of hard work. You deserve a business that works as hard as you do by keeping everything together on its own - hence the name Linchpin. I build the systems that make this possible, and I stand behind every one of them personally.

Frequently Asked Questions
What tools do you connect to? expand_more
We connect to thousands of tools, including the FSM platforms residential HVAC businesses already use, like Jobber, HouseCall Pro, ServiceTitan, Google Sheets, and more. We can also connect to Google Business Profile for review collection, invoicing and payment tools like Stripe or QuickBooks, and email platforms like Gmail, Google Workspace, Outlook, and Yahoo.
The goal is simple: make the tools you already use talk to each other when the right trigger happens.
How long does it take to setup? expand_more
Most builds take up to four weeks from signed agreement and 50% deposit, but many are completed faster. Timeline depends on the number of systems being built, the tools involved, and how quickly access is provided. We give you clear instructions for granting access, then build, test, and launch the automations as quickly as possible.
What happens if something breaks? expand_more
Monitoring, maintenance, and support are included in the monthly retainer. If something stops working, we fix it. You are not buying a system and getting left alone with it. Linchpin maintains the automations so they keep doing the job they were built to do.
Is there a contract? expand_more
We use a straightforward Client Service Agreement that covers scope, payment terms, confidentiality, cancellation, project timeline, and IP/data ownership. There is no long-term lock-in. You can cancel with 30 days’ notice.
What exactly does the Lead Response Automation do? expand_more
When a call to your business goes unanswered, the system automatically sends a personalized text message to the caller in under 60 seconds, logs the lead in your FSM, and sends you a notification with the lead’s details for priority callback. It handles the highest-dollar problem in HVAC: leads going cold while you’re on a job.
What are the other automation systems you offer? expand_more
Review Collection Automation - Triggers 2-4 hours after a job is marked complete in your FSM tool. Sends an SMS to the customer with a direct Google review link, followed by an email follow-up at 48 hours if no review has been submitted. Compounds your Google Business Profile ranking over time without anyone on your team remembering to ask.
Appointment Reminder Sequences - A booking confirmation fires immediately when an appointment is scheduled, followed by a 24-hour reminder and a 2-hour reminder. Reduces no-shows directly and measurably.
Unsold Estimate Follow-Up - When an estimate isn't converted to a job within 5-7 days, the system triggers an SMS and email follow-up sequence automatically. Recovers revenue from work you already invested diagnostic time in.
Maintenance Contract Renewal Sequences - Queries your FSM tool for contracts expiring in 30, 60, and 90 days and fires a systematic SMS and email sequence at each interval. Converts a spreadsheet-managed or completely manual process into a reliable recurring revenue protection system.
Dormant Customer Reactivation - Queries your FSM tool for customers with no service in 12-18 months and fires a seasonal SMS and email campaign. Turns a dormant database into booked jobs without any manual effort.
Seasonal Campaign Sequences - Customer list filtered by last service type, equipment age, or service area feeds pre-season tune-up campaigns, post-storm inspection campaigns, and equipment replacement conversations. Generates bookings that would never happen without the outreach.
New Customer Onboarding Sequence - First job booked triggers a welcome SMS with technician name and arrival window, a welcome email with pre-appointment instructions, and then feeds directly into the review collection sequence after the job completes.
Technician Dispatch and Job Status Communication - Technician marked en route triggers an automated SMS to the customer with ETA. Eliminates the "where is my technician" calls that drain dispatcher time.
Payment Reminder and Overdue Invoice Follow-Up - Invoice unpaid after a defined number of days triggers an SMS and email sequence. Reduces outstanding receivables without the owner making awkward manual collection calls.
Operational Workflow Automation - Internal routing logic: job assignments, internal alerts, invoicing triggers, QuickBooks sync. The connective tissue that makes the whole operation run without manual handoffs.
Reputation Monitoring and Response Alerts - New review detected triggers an owner alert and a drafted response suggestion. Keeps the owner engaged with his online reputation without monitoring it manually.
Employee and Technician Onboarding Automation - New hire triggers a structured checklist, document collection sequence, and training milestone reminders. Reduces the administrative burden of hiring in a labor-constrained industry.
Straightforward pricing. No surprises.
A single recovered job typically covers the monthly retainer entirely. The average HVAC business doing $1M in revenue already spends $2,500–$8,000 per month on marketing to generate inbound calls. This system makes sure that investment doesn’t go to waste the moment the phone rings.

The more systems you add, the less each one costs.
Most clients start with one system, see it recover real revenue within the first weeks, and come back to add more. We reward that momentum. Each additional automation you add as an existing client comes with a reduced setup fee and a smaller incremental increase to your retainer - not the full single-system rate.
The result: a fully automated HVAC operation that costs a fraction of what it would if each system were priced independently - and pays for itself many times over through leads recovered, reviews collected, estimates closed, and contracts renewed.
The pricing above is for a single automation system - most clients start with the Lead Response Automation as the highest-ROI entry point. Once it’s live and you’re recovering revenue, adding more systems costs you less per system, not more.
