Backup Power Maintenance Solutions

Most Generator Failures Happen for Preventable Reasons

Dead batteries top the list. Generator batteries wear out every two to three years, and if yours hasn’t been replaced recently, it’s probably not holding a charge. The weekly self-test helps, but it’s not enough.

Fuel issues come next. Contaminated diesel, gelled propane connections, clogged fuel lines—all of these stop your generator cold. Then there are the mechanical problems: dirty air filters restricting airflow, low oil triggering automatic shutdowns, coolant leaks causing overheating.

The transfer switch can fail too. It’s the brain that detects the outage and tells your generator to start. Worn contacts, wiring issues, or programming errors mean your generator never gets the signal.

Most of these problems show warning signs before they become total failures. Unusual noises during test cycles. Delayed startup. Error codes on the display panel. If you’re seeing any of that, you’re looking at a repair bill that’s only getting bigger the longer you wait.

Generator Engine Service & Repair

What's Included in Generator Repair Service

We start with diagnosis. Not guessing, not throwing parts at it—actual troubleshooting to find what’s wrong. That includes checking battery voltage and connections, testing the transfer switch operation, inspecting fuel supply and lines, examining air filters and oil levels, and verifying the control system.

Once we know the problem, we explain it. What failed, why it failed, what it costs to fix, and whether this is something that’s going to happen again if we don’t address the underlying cause.

Then we repair it. Generator battery replacement. Fuel system cleaning. Transfer switch repair or replacement. Engine components. Control board diagnostics. Whatever your generator needs to run reliably again.

We test everything before we leave. The generator has to start on command, transfer the load properly, run at the correct voltage, and shut down cleanly when utility power returns. If it doesn’t do all of that, we’re not done.

You get a local company that’s been serving these counties since 2002, not a national chain that subcontracts to whoever bids lowest. Our trucks are stocked. Our technicians are licensed. And when you call, you talk to someone who actually knows generators.

FAQ

Frequently Asked Questions

How often should I have my standby generator serviced?
Most generator manufacturers, including Generac, recommend professional service every six months or after every 200 hours of operation, whichever comes first. For most homeowners, that means twice-yearly maintenance. This isn’t just a suggestion—it’s often required to keep your warranty valid. Regular service catches small problems before they turn into expensive failures. During a maintenance visit, our technicians check and replace the oil and filter, test the battery and charging system, inspect the air filter, verify coolant levels, test the transfer switch operation, and run a load test to make sure the generator can actually handle your home’s power needs. If you’re only running the weekly self-test and skipping professional maintenance, you’re setting yourself up for a failure during the next real outage. The self-test doesn’t catch everything, and by the time you notice a problem, you’re usually looking at a repair instead of a simple maintenance fix.
The most common reason is a dead or weak battery. Generator batteries typically last two to three years, and if yours is older than that, it’s probably not holding enough charge to crank the engine. The weekly self-test helps maintain the battery, but it’s not a substitute for replacement when the battery reaches the end of its life. Other common causes include fuel supply issues—contaminated fuel, closed fuel valves, or clogged fuel lines can all prevent startup. Low oil levels trigger an automatic shutdown feature that won’t let the generator start until you add oil. Transfer switch problems can also be the culprit—if the switch doesn’t detect the outage or can’t send the start signal, your generator never gets the command to turn on. Sometimes it’s as simple as the control switch being in the wrong position after a service call or if someone hit the emergency stop button. If your generator won’t start, check the basics first: battery connections, fuel supply, and oil level. But if those all look good and it still won’t start, you need a certified technician to diagnose the actual problem before you end up replacing parts that aren’t broken.
Some basic maintenance you can handle yourself—checking oil levels, keeping the area around the generator clear, making sure the unit isn’t blocked by debris. But actual repairs should be left to certified professionals for several important reasons. First, your warranty probably requires it. Most manufacturer warranties, including Generac’s, specify that repairs must be performed by authorized service dealers. If an unlicensed person works on your generator and something goes wrong, your warranty won’t cover it—meaning you’re paying for both the bad repair and the professional fix. Second, generators involve both high-voltage electrical systems and fuel systems, which create serious safety hazards if you don’t know what you’re doing. Transfer switches operate at voltages that can kill you. Gas and propane lines require proper certification to work on safely. Third, modern generators use complex control systems and sensors that require proper diagnostic equipment to troubleshoot. Guessing at the problem and replacing random parts usually costs more than calling a professional in the first place. There’s also the issue of getting the right parts—many generator components are specific to certain models and years, and using the wrong part can cause more problems than it solves.
Repair costs depend entirely on what’s wrong with your generator. A simple battery replacement might run a few hundred dollars including labor. Transfer switch repairs can range from minor fixes to complete replacement depending on what failed. Engine repairs vary based on which components need attention. Fuel system cleaning, control board replacement, and other repairs all have different costs. That’s why we provide flat-rate quotes before starting any work—you know exactly what you’re paying before we touch your generator. No hourly billing, no surprise charges, no “we found additional problems” upcharges unless we call you first and get approval. The real cost question isn’t what repair costs—it’s what failure costs. If your generator doesn’t work during a multi-day outage, you’re looking at spoiled food, potential pipe damage if it’s winter, no heat or air conditioning, and the general misery of being without power while your neighbors’ lights are on. Regular maintenance costs less than emergency repairs, and emergency repairs cost less than replacing a generator that failed because it wasn’t maintained. The most expensive generator repair is the one you need right when a storm hits and every technician in the area is booked solid for the next week.
We service all major generator brands and models—Generac, Briggs & Stratton, Kohler, Cummins, Champion, and others. Our technicians are factory-authorized and certified specifically for Generac and Briggs & Stratton systems, which means we have specialized training and access to technical resources for those brands. But we’ve been working on generators across Alamance, Durham, Chatham, and Orange County since 2002, and that experience covers pretty much every residential and commercial generator system you’ll find in this area. Whether you have a natural gas, propane, or diesel generator, whether it’s a whole-house system or a smaller unit covering essential circuits, we have the diagnostic equipment and parts access to get it repaired. The advantage of working with factory-authorized technicians is that we stay current on technical bulletins, common failure points, and proper repair procedures for the brands we’re certified on. We’re not learning on your equipment or guessing at solutions—we know these systems inside and out because we work on them every day.
Most repairs are completed the same day, often within a few hours, because our service trucks carry common replacement parts. If we’re replacing a battery, cleaning a fuel system, or repairing a transfer switch with parts we have on hand, you’re looking at a few hours from diagnosis to testing. More complex repairs that require ordering specific parts might take a few days depending on parts availability—though we stock a large inventory specifically to avoid that delay whenever possible. Emergency repairs during storm season obviously get priority response, but even then, we’re not making you wait days for service. The actual repair time depends on what’s wrong. A battery swap is quick. A complete transfer switch replacement takes longer. Engine repairs vary based on which components need attention. But here’s what you won’t get from us: unnecessary delays, parts ordered that we should have stocked, or technicians who show up without the tools to complete the job. We’ve been doing this for over 20 years in these counties. We know what fails, we know what parts to carry, and we show up ready to actually fix your generator, not schedule a second visit to finish what should have been done the first time.
