How It Works Pricing FAQ Support Get Started Free →

HVAC software that runs
on your voice.

You didn't get into heating and air to type line items in a driveway. Describe the job out loud, "replaced the capacitor and two pounds of R-410A, three hours labor", and FieldForge builds the invoice from your own price book, texts the customer a pay link, and marks the job paid before you've packed the gauges.

Watch a real HVAC job become a paid invoice

This is the whole workflow (voice note to customer-ready invoice) recorded on a real repair. Sixty seconds, no typing.

Built around how an HVAC shop actually works

An HVAC parts book, day one

Your price list ships pre-loaded with an HVAC catalog (capacitors, contactors, refrigerant by the pound, condenser fan motors) with your cost and margin per line. Say the part; it prices itself on the invoice.

Equipment & warranty tracking

Every unit you touch gets a record: refrigerant type, tonnage, SEER, filter size, install date, warranty expiration, with reminders before coverage or maintenance comes due. Next visit, your tech arrives already knowing the system.

Tune-up contracts on autopilot

Sell a maintenance agreement once; FieldForge generates the spring and fall visits and the recurring invoices. Steady winter revenue without a spreadsheet.

Your phone, answered, Front Desk

In a July heat wave you can't answer while you're in an attic. Front Desk picks up 24/7, triages like a trained CSR (no-cool vs. no-start, system age, gas-smell safety), quotes your service fee, and books the job into your real schedule.

Dispatch, timesheets & tech pay

Drag jobs onto techs, optimize the day's route, clock hours from the app, and pay any mix of hourly, commission and spiffs. Techs watch their week's earnings live on My Pay.

Estimates that close installs

Speak a system-replacement quote on-site, customer approves online with a signature, one tap converts it to the invoice. QuickBooks stays synced by itself.

Why HVAC crews switch

The billing backlog dies. The invoice happens at the job, spoken in thirty seconds (in English or Spanish) so nothing waits for "tonight." Shops that switch tell us the same thing: unbilled work simply stopped existing.

The busy season stops eating you. Peak cooling season is exactly when you miss the most calls and lose the most jobs. Online booking, automatic customer reminders, and the Front Desk receptionist catch the work you used to lose to voicemail.

The price doesn't punish growth. Free to start. A three-tech shop pays $29/month flat, not per user, no contracts. Compare that to the $200+ a month the big platforms reach once add-ons stack up: see the honest math in FieldForge vs Jobber, vs Housecall Pro, and vs ServiceTitan.

Quick answers

What's the best invoicing app for a solo HVAC tech?

One you'll actually use from the truck. FieldForge builds the invoice from a spoken description (parts priced from your own book, labor and tax automatic) and texts a pay-by-card link. The Solo plan is free, forever.

Does it track refrigerant, tonnage and SEER?

Yes, the equipment record ships with HVAC fields (refrigerant type, tonnage, SEER, filter size) and you can customize them per shop.

Can my Spanish-speaking techs use it?

Fully. Voice notes work in Spanish, the app is bilingual, and invoices come out clean and professional either way.

What does it cost?

Free for a solo tech (15 invoices/month). Paid plans from $19/month; a 3-tech crew is $29/month flat. The Front Desk AI receptionist is a $49/month add-on. No per-user fees, no contracts.
