Import, merge and backup for HVAC projects

MechLedger HVAC uses project and backup files for transfer, archiving and restore-as-new workflows. It does not present cloud sync or real-time collaboration.

.hvacproject

One project as a transfer package

.hvacproject is for a single project and can include project data, calculations, actions, folders, photos and files.

Export project Create a project package with preview information.

.hvacbackup

Backup for all or selected projects

The backup workflow is designed for storing and moving multiple projects, with full or lightweight package options.

Full backup

Includes project packages with photos and files when complete documentation is needed.

Lightweight backup

Keeps a smaller package with metadata and core project data without large media files.

Restore as new projects

The current restore flow creates new projects and does not claim to overwrite existing ones.

These descriptions follow the current app implementation and avoid claims about cloud accounts or collaborative web dashboards.
