Many electrical contractors provide service, maintenance and repair of electrical equipment at the customer's premises.
Both residential and business customers use electrical service and repair. These are small projects that can be accomplished in a single visit. Service work is usually billed on cost-plus-fee basis or a flat fee schedule.
Some electrical contractors offer maintenance contracts for regular preventive maintenance of entire electrical systems or for specific items of electrical equipment. This specialized service often requires dedicated tools and diagnostic equipment and scheduled inspections or adjustments by the electrical contractor.
An electrical contractor's service operation may consist of a single-service electrician who serves only the needs of the contractor's regular customers, or a fleet of service trucks who respond on demand to multiple customer requests in an area.
