Our Process

How a Service Call Works

1

Call or Submit Online

Tell us the building, the symptom and the access requirements. We confirm a window same day where the schedule allows.

2

Diagnose On Site

The tech isolates the actual failure — camera, meter or pressure test — instead of guessing at parts.

3

Repair or Quote

Small repairs are handled on the spot. Larger scopes get a written quote before anyone spends your money.

4

Report & Follow-Up

You get documentation of what failed, what was replaced and what should be watched next.

Why Choose Legacy for Service & Repair

Why Facility Managers Keep Our Number

Scheduled service 7am–4pm Mon–Fri

We do not pretend to have a night crew. We do get you on the board fast during service hours.

Licensed commercial service techs

Master-licensed supervision on commercial systems, not residential techs learning on your building.

History on your building

Recurring customers get documented service history so the next tech is not starting from zero.

Backed by a construction division

When a repair turns into a replacement, the same company can price and build it.
