About

HVAC Field Report

Features
Read full description

HVAC Field Report turns the visit you just finished into a customer-ready service report — in about two minutes, standing at the truck. Built for the independent residential and light-commercial technician: gloves on, dirty hands, no signal, several calls a day. DICTATE INSTEAD OF TYPING Talk through the visit the way you'd explain it to the customer. Field Report organizes what you said into complaint, findings, work performed, and recommendations. Every number it pulls out — pressures, temperatures, superheat, subcooling, capacitor readings — is shown to you for review before it lands on the report. You can always type instead of talking. CAPTURE THE NAMEPLATE, NOT YOUR HANDWRITING Photograph a filthy outdoor nameplate and Field Report reads the model and serial off it. Both start unticked: nothing goes on the report until you confirm it. EQUIPMENT HISTORY THAT REMEMBERS Every unit keeps its own record. Search by customer, address, model, or serial — whichever one you actually remember. A PDF THE CUSTOMER CAN READ Clean, selectable, printable. Your business name, logo, and license number in the header. Photos, a maintenance checklist, and a signature or typed acknowledgment. Internal notes and internal-only photos never appear on the customer copy. WORKS WITH NO SIGNAL Everything is stored on your device. There is no account, no login, and no developer-operated server. Attics and basements don't break it. FREE PLAN Three finalized reports, ten equipment records, and the three most recent visits per unit. Everything you finalize stays yours — viewable, shareable, and exportable forever, subscription or not. FIELD REPORT PRO Unlimited finalized reports, your logo on the customer PDF, complete equipment history, and checklist customization. WHAT THIS APP DOES NOT DO Field Report organizes information that you supply. It does not diagnose equipment, size systems, or decide whether a unit is operating correctly — those are your professional judgment. It does not certify compliance with any federal, state, or local reporting rule, and it does not determine whether such rules apply to a given refrigerant transaction. Every reading, finding, and recommendation on a report is what the technician entered or confirmed. AUTOMATIC RENEWABLE SUBSCRIPTIONS Field Report Pro is sold as an auto-renewable subscription through the App Store. The app is governed by Apple’s Standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
