What is AC Tech Manager?
AC Tech Manager is a professional application designed for HVAC technicians and air conditioning service businesses. It helps you create invoices, quotations, manage clients, track payments, and generate business reports — from your phone or PC, without needing internet access.
What platforms does it support?
AC Tech Manager is available as an Android application and as a desktop application for Windows. Use it on your phone in the field or on your PC at the office.
Does the app require an internet connection?
No. AC Tech Manager is fully offline. All data is stored locally on your device using SQLite. There are no accounts, no cloud sync, and no external API calls. Your data never leaves your device.

Yes. Since all data is stored locally on your device and never transmitted to any server, your business information remains completely private. You can also export backups as JSON files for safekeeping.
What payment methods does AC Tech Manager process?
AC Tech Manager does not process payments. It is an invoicing and document management tool. You handle payments with your clients directly. The app helps you track which invoices are paid or unpaid.
