Scheduling & dispatch
Tune-ups, emergencies and install days share one drag-and-drop board. Assign the nearest tech and the customer gets the ETA text automatically.
24/7 answering for HVAC emergencies
Voicemail doesn't fix furnaces.
Peak season floods the line, and every no-heat or no-cool call is an emergency to the person making it. Linq answers what you can't: it books the job, sets expectations, pings the on-call tech and texts back every missed call in seconds. The first hot Saturday of summer stops being a triage problem.

24/7 answering for HVAC emergencies
HVAC scheduling, dispatch & CRM
Service, installs and maintenance on one board.
Estimates on site
Price the repair and the replacement at the kitchen table, send both to the customer's phone, and collect the signature and deposit before you leave the driveway.
Maintenance agreements & reminders
Agreement customers ride a reminder cycle, so spring and fall tune-ups book themselves instead of waiting on a phone blitz.
Invoicing & tap-to-pay
The invoice is ready when the panel closes. Tap the card on your phone or send a pay link and watch it clear.
Customer & equipment records
Every address keeps its equipment details, photos, filter sizes and full service history, so the tech walks in knowing the unit better than the homeowner does.
Plain-English reports
Seasonal revenue, agreement counts, techs and lead sources in sentences and simple charts. Know which season paid for the new van.
How it works
One no-cool call, start to finish.
- 6:41 AM, first hot Saturday in June A no-cool call comes in. Linq answers while you're still asleep and books the morning slot.
- 9:15 AM Tech dispatched, ETA texted, the unit's service history already on their phone.
- 10:40 AM Capacitor swapped, invoice tapped on the porch. The estimate for the aging condenser is signed on the same visit.
- September The fall tune-up reminder goes out on its own, and the customer books before your competitor's postcard even prints.
Built with tradespeople
Made in a service van, not a boardroom.
Linq was built in partnership with working trade businesses that run 24/7 emergency dispatch, and HVAC runs on the same physics: after-hours calls, mobile techs, on-site decisions, payment at the door. The software assumes you are in a driveway, not at a desk, because that is where it learned the job.
Pricing
One flat price. Every tech included.
Everything on this page is included from $179 a month: answering, dispatch, estimates, invoicing, payments and the phone line. Flat tiers instead of per-tech seats, so staffing up for summer costs nothing extra. /pricing Basic $89, Growth $179, Scale $249, Enterprise $349
Try it on a real week
Fourteen days. Your actual jobs.
Not a sandbox with fake customers in it. Put a real week through the board, answer real calls with it, and see what the Friday number looks like. Fourteen days, no card, cancel any day.
HVAC software questions
What is the best HVAC software for a small business?
For a small HVAC business the software has to do five jobs without an office admin: answer the phone, schedule, dispatch, estimate and invoice. Linq does all five in one app at one flat price, so a two-tech shop runs on the same machine a fifty-tech operation pays enterprise money for.
Does Linq handle maintenance agreements?
Linq keeps every agreement customer on a reminder cycle, so seasonal tune-ups book themselves, and the equipment history rides along on every visit.
Can I build HVAC estimates and proposals on site?
Yes. Build the estimate at the kitchen table, put the repair and the replacement side by side, and collect the signature and deposit on the spot. Everything lands on the same job record.
Does Linq work with QuickBooks?
Yes. Connect QuickBooks Online and your sent and paid invoices sync across with their line items and the customer they belong to.
How is Linq priced for HVAC crews?
Flat tiers, not per-tech seats: Basic $89, Growth $179, Scale $249, Enterprise $349. Everything is included at every tier. Adding a tech in July costs nothing extra. Basic $89, Growth $179, Scale $249, Enterprise $349
Is Linq a ServiceTitan alternative for small HVAC shops?
For small and mid-size shops, yes. ServiceTitan is built and priced for large operations, with onboarding to match. Linq covers the parts that make the money (dispatch, estimates, agreement reminders, invoicing, 24/7 answering) at a flat monthly price you can cancel anytime.
