Why Backup Power Fails When You Need It Most

Generators often fail for mundane reasons: a drained battery, stale oil, a blocked air filter, or a worn spark plug may leave the unit dead when the power goes out. Rodents can cause trouble, too. Mice frequently nest inside the housing and chew through wiring. An automatic exercise cycle helps reveal problems, but it will not find every one. Standby generator maintenance in Woburn, MA checks the components that deteriorate over time before a storm exposes the problem. Home generator maintenance in Woburn, MA also covers the transfer switch, the device that signals the generator to take over. Every service call is performed under MA License #59750B, covering the electrical system as carefully as the engine.

What a Real Tune-Up Should Cover

A quick look at the control panel doesn’t count as maintenance. Proper residential generator service in Woburn, MA, includes replacing the oil and filters, inspecting the spark plugs, testing the battery, removing debris, and running the generator under load to confirm it can power the house. Most standby units need that service at least once a year, with an additional inspection after a prolonged outage if the generator operated for several days. Portable models need attention as well: use fresh fuel and start the unit before storm season. For businesses, commercial generator maintenance in Woburn, MA keeps essential backup systems ready, refrigeration, security equipment, servers, and other operations that cannot go down. After every visit, we explain what we inspected, what we found, and what needs watching.

Ready When the Next Nor’easter Hits

The worst moment to discover that your generator will not start is during a nighttime outage. When a unit refuses to run, stops halfway through an outage, or displays an unfamiliar warning light, WG Supra Services provides emergency generator maintenance in Woburn, MA. We diagnose the problem and restore operation when we can. A fall service appointment may prevent the emergency call in the first place, giving your generator a chance to be ready before winter storms bring down power lines across the region. Routine maintenance can extend its life and catch minor problems before they become expensive repairs. You receive the price before work begins, along with straightforward advice when replacing the generator makes more sense than repairing it.

How a Service Visit Goes

Inspection and history: We examine the unit, review its operating hours and error log, then ask about any problems you’ve noticed.
Engine and battery care: We change the oil and filters, inspect the spark plugs, test the battery, and replace worn parts after you approve the work.
Transfer Switch Test: We check that the transfer switch moves power to the generator during an outage and returns it to the utility afterward.
Load Run and Report: The generator runs under load while we check its performance. Once the test is complete, we explain our findings and point out anything to monitor.

Frequently Asked Questions

How can I tell when my generator needs servicing?

Warning lights, difficult starts, uneven operation, or a skipped exercise cycle can all signal trouble. If you don’t remember when it was last serviced, schedule one.

Do you service portable generators?

Yes. Portable generators need fresh fuel, regular oil changes, and test runs. We can also inspect the inlet and transfer equipment that connects the unit to your home.

What does a transfer switch do?

It switches your home from utility electricity to generator power, then switches it back when utility service returns. If the switch fails, the generator can run while your house receives no power.

Should I run my generator between outages?

Standby generators perform brief self-tests automatically. Portable models need to be started and run briefly about once a month so they remain ready for use.

What if my generator won’t start during an outage?

Call us first. Check the fuel, then confirm that the unit is set to “Auto” or “On.” Do not open the housing or handle the transfer switch yourself.
