Residential and Commercial Generator Maintenance
Generators for homes and businesses share the same job: keeping the power on when the utility grid is down. However, each system needs distinct care. At Corbin Electrical Services, Inc., our technicians are trained in both, and we tailor every maintenance visit to the type of unit and how it’s used. We can service any model of generator, whether Generac, Cummins, Kohler, Honeywell, or Briggs & Stratton.

Residential Generators
A home standby generator lets your family stay put during an extended outage instead of using candlelight or losing a whole fridge full of food. Residential units are often simpler than commercial systems, but they still need a yearly inspection to catch problems before they turn into major issues or keep your generator from working when you need it most. Our technicians check the essentials, from engine oil and wiring to filters and battery conditions, so your generator starts the moment your power goes out.

Commercial Generators
Commercial generators tend to have more components to check and test, which makes diagnosing problems more involved. Our skilled professionals are equipped for that complexity, and we make sure anyone on-site who may need to operate your generator knows how to do so safely. Because an outage at your facility can mean lost revenue or compromised data, we treat these maintenance visits with the same urgency your business does.
Generator Maintenance Checklist
Whether we’re servicing a residential or commercial unit, our technicians work through a detailed checklist. This list allows us to catch issues while they’re still small and inexpensive to fix. A typical visit includes:
- Assessing all wiring and electrical components
- Cleaning and tightening bolts and connections
- Changing engine oil and replacing filters
- Inspecting air filters, spark plugs, and other essential parts
- Checking for and repairing any fuel or oil leaks
- Monitoring coolant levels
- Testing air intake ventilation systems
- Field-testing the unit and completing any manufacturer software updates
Not every item applies to every unit, but a trusted technician knows how to move through the list quickly without skipping every essential step. We use only factory-authorized parts and send out factory-trained mechanics, so you can trust our process as much as our results.
Monitor Backup Generators Remotely
While maintenance keeps your generator running, monitoring tells you what’s happening with it. For customers with Generac units, we offer Mobile Link Dealer-Managed Wi-Fi Connectivity, which lets you check your generator’s status right from your smartphone or tablet. You can check whether it’s ready to use, currently running, or in need of service.
You’ll get an alert as soon as something breaks or stops working. Free service comes standard with all 2019 Guardian Series and newer Generac standby generators. Additionally, Active Service is available for those who want notifications, maintenance history, and local weather updates in one place.

Frequently Asked Questions About Generator Maintenance
How often should I schedule generator maintenance?
Most units need a professional inspection once a year. If you use your generator a lot, a second visit partway through the year is recommended.
What happens during generator maintenance?
During a maintenance visit, a technician:
- Inspects major mechanical and electrical components
- Tests the battery
- Checks fluids and filters
- Evaluates the fuel system
- Inspects the transfer switch
- Performs diagnostics
- Verifies proper use
Can I maintain my generator myself?
You can perform basic visual inspections and remove debris around the generator. However, a qualified technician should always complete electrical testing, engine service, and diagnostics.
Why does my generator run even when the power hasn’t gone out?
Most standby generators automatically perform scheduled exercise cycles. These routine self-tests help keep the engine lubricated and verify the system is ready for future outages.
Is remote generator monitoring worth it?
For many home and business owners, yes. Remote monitoring provides maintenance reminders, system alerts, and status updates that help identify potential issues before they become major problems.
Do you offer maintenance agreements?
Yes. At Corbin Electrical Services, Inc., our maintenance agreements include priority scheduling, regular service visits, and repairs made with factory-authorized parts.
