You Already Made the Investment. We Make Sure It Works When You Need It.
You bought a standby generator so you'd never have to think about a power outage again. But a generator that hasn't been serviced in a year or two isn't a safety net — it's a question mark. Most standby generators fail silently between outages: a dead battery, a stuck transfer switch, or low oil doesn't show up on your radar until the moment the power actually goes out.
DisplayMax Electric provides complete standby generator services for homeowners and businesses throughout southeastern and mid Michigan — regardless of who installed your unit or which brand you own. We service a range of systems, so switching to us for service never means switching your equipment.
A generator's automatic self-exercise cycle is designed to reassure you — but it isn't a substitute for a technician's inspection. Scheduled inspections, oil and filter service, and battery and transfer switch testing that keep your unit ready before the power ever goes out.
If your standby generator failed to start during an outage, tripped a fault code, or isn't running the way it used to, we can help — regardless of the brand or who installed it. Our technicians diagnose and repair residential and commercial systems.
Most generator failures aren't discovered until the power actually goes out — because that's the only time anyone checks. Remote monitoring changes that. A connected monitoring device keeps watch on your unit around the clock and sends an alert the moment something needs attention
If a standby generator fails to start, the cause is more often the battery or the transfer switch than the generator itself. Both are wear components with a limited service life, and both are far cheaper to replace on a planned schedule than to discover as a failure during an actual outage.
Why a Generator Needs Ongoing Service
A standby generator is a mechanical system that sits idle most of the year and is expected to perform flawlessly the moment it's needed most. That combination — long periods of inactivity followed by high-stakes demand — is exactly the profile of equipment that fails quietly. Batteries lose charge. Oil breaks down. Rodents chew wiring harnesses. Automatic exercise cycles can mask a real problem if no one is reviewing the results.
Regular service catches these issues while they're still inexpensive, scheduled, and non-emergency. Waiting until the generator fails to start during an actual outage turns a routine maintenance item into an emergency repair — usually at the worst possible time.
Yes. The majority of our maintenance and repair customers had their generator installed by another company or by the home’s previous owner. We service major brands regardless of who sold or installed the unit.
A full inspection covering oil and filter condition, battery health and charging system, transfer switch function, fuel supply, exercise-cycle logs, and a run-time test. Specific scope varies by plan — see our Maintenance Plans.
Most manufacturers recommend service at least once a year; twice a year is common for units under heavy use or in harsher operating conditions. Your specific interval depends on brand, run hours, and local conditions — we’ll recommend a schedule during your first visit.
You’ll receive a written report with photos and a clear recommendation. Any repair work is quoted separately and requires your approval before we proceed — a maintenance visit never turns into surprise repair charges.
