When the power goes out, your standby system has one job. Carter's maintenance agreements make sure it's ready — regular inspections, organized documentation, and the same trusted technicians on every visit, year after year.
A Carter Customer Value Agreement (CVA) consolidates scheduled maintenance, parts, testing, documentation, and equipment monitoring into a single annual program. Carter manages the schedule, tracks equipment history per unit, and handles compliance documentation automatically. The same technicians return visit after visit, building familiarity with each unit and its service history.


Standby systems fail at predictable points — batteries, fuel, controls, breaker contacts — and almost always while idle. A CVA puts those failure modes on a maintenance calendar before they reach the point of failure.
Travel, scheduling, and labor are consolidated into a single annual agreement — so unscheduled diagnostic visits, after-hours dispatch fees, and emergency parts ordering are kept to a minimum. Spreading maintenance cost over the year makes facility budgeting more predictable and eliminates surprise expenses.
For facilities under accreditation or compliance requirements, the CVA locks in the inspection schedule automatically — quarterly for healthcare under NFPA 110, annual or semi-annual for most commercial and industrial standby installations. Carter manages the schedule without the facility team having to track it.
Sometimes a CVA visit surfaces something bigger — controls that are no longer supported, switchgear that no longer matches load requirements, or infrastructure that needs modernization. Carter’s Engineering Services group handles those projects in-house, through the same service relationship.
Whether you're setting up a new maintenance program or reviewing existing coverage, a Carter power specialist can assess your equipment and recommend the right approach.
