    The problems costing you jobs

    Every hvac business loses revenue the same way. Here's what KoreFSM fixes first.

    Emergency calls go to voicemail

    After-hours AC failures are won by whoever answers first. KoreAI answers, qualifies, and books — 24/7.

    Maintenance agreements slip

    Recurring service agreements auto-generate jobs and invoices on schedule — no spreadsheet reminders.

    Techs re-diagnose from scratch

    Per-unit equipment history (serial, refrigerant, past repairs) travels with the customer record.

    How it works

    A job on KoreFSM, start to finish

    From the first phone call to the final payment — one connected flow.

    1

    Capture the call

    KoreAI answers emergency and after-hours calls, captures system type and symptoms, and books the visit.

    2

    Dispatch the right tech

    Map-based dispatch sends the closest tech with the unit's full service history attached.

    3

    Fix it on-site

    Techs work offline in basements and attics — diagnostics, photos, and signatures sync when signal returns.

    4

    Bill and follow up

    Invoice on completion, auto-schedule the next maintenance visit, keep the agreement revenue recurring.

    Trade-specific depth

    Built for how hvac actually works

    Trade-specific fields and workflows — not a generic tool with your industry's name on it.

    System diagnostics fields

    System type, tonnage, SEER, refrigerant, ductwork condition, static pressure — captured on every job, not in a notebook.

    Maintenance agreements

    Recurring billing + auto-scheduled visits. The #1 retention feature in residential HVAC, built in.

    Permit & inspection tracking

    Permit numbers, inspection status, and checklists tied to the job — nothing falls through at final inspection.

    Offline field mode

    Basements and attics have no signal. Techs complete jobs, take photos, and collect signatures offline — it syncs later.
