Choose the backup-power method before choosing the equipment
A standby generator and a portable generator connection solve different problems. An automatic standby system can monitor utility power and transfer selected or managed loads without the homeowner moving equipment outside. A portable setup requires the customer to position and operate the generator safely, connect the approved cord and follow the manual transfer or interlock sequence.
Landmark begins with the loads the customer wants to support, the existing electrical service, available panel capacity, site and fuel conditions, transfer method and desired level of automation. The result is a project-specific backup-power path rather than a generator selected only from its advertised wattage.

Generac backup-power expertise
Plan the generator, transfer strategy and backed-up loads as one system.
Landmark Electric installs and services Generac residential standby generators across Metro Detroit. The planning process connects household priorities, electrical capacity, automatic transfer equipment, fuel delivery, code requirements, startup and owner orientation before the final equipment is selected.

Generator Services options
Choose the focused service that matches the repair, installation, inspection or planning need. Each page contains 6–9 or more specific services and explains its own scope, hazards, project variables, process and related options.
Flexible payment options
Financing is available for qualifying electrical projects.
Landmark works with independent finance companies to offer qualified customers a range of payment-plan options. Review the available providers and continue through the provider you choose.
The electrical, fuel and site scopes must work together
A complete standby-generator project coordinates the generator location, clearances, mounting, electrical feeder, transfer equipment, grounding and bonding, service configuration, control wiring, fuel demand, gas-meter or regulator capacity, permits and startup requirements. Fuel-system work is completed by the appropriate licensed trade when it is outside Landmark's accepted scope.
Utility, municipal, manufacturer and property requirements can affect placement and scheduling. The written proposal identifies Landmark's electrical work, equipment supplied, customer responsibilities and work assigned to another contractor.
Maintenance and repair are separate from installation
Generator maintenance intervals depend on model, engine, operating hours and manufacturer instructions. Extended outage runtime can make service necessary before the next annual appointment. Landmark offers a one-time essential maintenance service and three generator maintenance plans with different inspection, testing, priority and dispatch benefits.
A no-start, failed exercise cycle, alarm, weak battery, transfer problem or fuel concern requires diagnosis. Maintenance parts do not automatically correct an operating fault, and diagnostic or repair work is separately authorized unless the written plan or service scope states otherwise.
Codes and standards that apply
These references explain the framework for this work. The adopted code, Michigan amendments, local authority, utility rules, equipment listings and manufacturer instructions must be considered together for the actual installation.
Frequently asked questions
Does Landmark install both standby and portable generator connections?
Yes. Landmark installs Generac residential standby systems and approved portable-generator inlet, breaker and listed interlock arrangements. The equipment, service capacity and transfer method are evaluated before the scope is finalized.
Can a generator power the entire house?
Possibly, but whole-home support depends on the generator, service, connected loads, motor starting, fuel capacity and load-management strategy. Landmark verifies the project rather than treating the service rating as the required generator size.
Does Landmark maintain generators it did not install?
Landmark can service qualifying Generac residential air-cooled standby generators up to 26 kW when the model, condition, access and parts requirements fit the offered service. Existing alarms or failures may require separate diagnosis.

What your service visit includes
Your $79 dispatch and evaluation charge covers sending an electrical professional to your property and the initial on-site evaluation. During that evaluation, the electrician examines the relevant accessible system, shows or explains the supported findings and identifies the cause when the available evidence reasonably allows. Clear, flat-rate options are presented before approved work begins, and the charge is waived when you proceed with approved work during the visit. Any special access, extended diagnosis, permit or after-hours considerations are explained before work moves forward.
