Maintenance estimates your team can defend, line by line.

AirHandler Pro turns equipment lists and service scopes into priced maintenance estimates using a verified task catalog — with revision history, approval control and consistent gross margin.

Catalog-driven scope

Equipment types, service scopes and task rules come from one published, immutable maintenance catalog.

Margin-based pricing

Revenue is derived from cost and a gross-margin target — never by adding margin on top of cost.

Revisions, not overwrites

Each estimate keeps its revision history, and approved revisions stay immutable evidence.

Enforced at the database

Company scoping, roles and lifecycle rules are enforced server-side, not in the browser.
