It’s easy to forget about a standby generator when the lights are on. Then a winter storm rolls through, the house goes dark, and suddenly you’re wondering whether the battery, fuel supply, and automatic transfer switch are all ready to do their jobs.
If you’ve ever spent a holiday outage charging phones in the car or trying to keep the house comfortable while waiting for power to return, you know why readiness matters. A generator is only dependable when it’s maintained.
With DFW heading into a forecasted rough winter, fall is a smart time to get ahead of service, not after the first freeze or outage. Here’s a straightforward guide to generator maintenance for homeowners and business owners.
What generator maintenance involves
A standby generator is designed to start automatically when utility power fails. But automatic doesn’t mean maintenance-free. Like other engines and electrical equipment, it needs routine inspection and service to help ensure it can start, transfer power, and operate as intended.
The exact service schedule depends on the make, model, fuel type, operating hours, and installation. Your owner’s manual is the place to check model-specific intervals. Kohler’s maintenance schedule guidance is also a helpful reference for understanding why regular service matters.
For many standby generators, a professional service visit may include oil and filter service, air-filter inspection, battery testing, fuel-system checks, and inspection of electrical connections and controls. A technician can also assess the automatic transfer switch and run appropriate operational tests. These checks help identify small issues before an outage puts the system to work.
A simple pre-winter readiness checklist
You don’t need to open up the generator or do mechanical work to keep an eye on its condition. These basic observations can help you spot when it’s time to call a qualified technician.
1. Check the controller for alerts
Look at the generator’s display or controller for warning lights, fault messages, or other alerts. If you see a code you don’t recognize, write it down and contact a qualified service provider. Don’t ignore an alarm just because the generator appears to be running normally.
2. Make sure the automatic exercise schedule is active
Many standby generators run automatic exercise cycles to help keep the unit ready. Check your owner’s manual for the right schedule and what a normal exercise looks and sounds like for your model. Schedules and settings can vary, so don’t change them based on a general rule of thumb.
An exercise cycle is useful, but it doesn’t replace routine service or prove every part of the system is ready for a real outage.
3. Keep the area around the generator clear
When the generator is off and cool, look for leaves, branches, stored items, or other debris around the enclosure. Keep the manufacturer-required clearances and make sure air openings and the exhaust path aren’t blocked. After a storm, check for fallen branches or debris.
Never cover a running generator or place anything where it could obstruct ventilation or exhaust.
4. Look for visible changes
From outside the enclosure, check for obvious damage, loose-looking parts, unusual corrosion, or signs of a leak. Don’t open the unit to investigate. If you notice a fuel odor, visible damage, or a puddle that could be oil or another fluid, keep clear and contact a qualified professional.
5. Pay attention to sound and performance
You know the usual sound of your generator’s exercise cycle. If it suddenly sounds different, vibrates unusually, produces unusual smoke, or stops before the cycle is complete, make a note of what happened and arrange an inspection.
6. Keep service records handy
Save the date and details of each maintenance visit, along with any service notes or recommendations. If an alert appears or your generator runs during an outage, those records can help a technician understand its recent history.
What to leave to a qualified technician
Some maintenance involves engine oil, filters, batteries, fuel connections, wiring, controls, and transfer equipment. These aren’t good places to guess or improvise. Don’t open energized equipment, adjust fuel fittings, or attempt repairs unless you’re qualified and following the exact instructions for your model.
During a scheduled visit, a trained technician can inspect and service components according to the manufacturer’s maintenance schedule. That may include oil and filter replacement, air-filter and spark-plug checks, battery and charger testing, fuel-system inspection, controller diagnostics, and operational testing. The technician can also check the transfer switch. The part that moves the electrical load between utility power and the generator.
The right tasks and timing vary by unit. A generator that has run for extended periods may need service sooner than one that has only completed its regular exercise cycles. For detailed product-specific information, consult Kohler’s service and maintenance resources and your generator’s owner’s manual.
Residential and commercial generators have different needs
A natural gas or propane whole house generator helps a family keep important household systems running during an outage. But even if it starts automatically, the engine, battery, fuel supply, and transfer equipment all need appropriate attention.
For businesses, the stakes can be different. A diesel-powered commercial generator may support essential equipment, refrigeration, communications, or operations that are costly to interrupt. Service needs depend on the specific unit and how it’s used, so business owners should work with a qualified provider on a maintenance schedule that reflects the equipment, runtime, and site requirements.

Why fall is a good time to schedule service
In Dallas–Fort Worth, winter weather can change quickly. Waiting until a freeze warning or an outage is already underway can make it harder to get service when you need it most. Scheduling generator maintenance in fall gives you time to address recommended repairs and ask questions before colder weather arrives.
Think of it like checking the smoke alarms before holiday guests arrive: it’s a small step that can make a stressful situation easier to handle. Imagine waking up to a winter outage and knowing your generator has been inspected, the controller shows no alerts, and the area around the unit is clear. That peace of mind starts before the grid goes down.
Make generator maintenance part of your outage plan
A few safe visual checks can help you notice changes, but they aren’t a substitute for professional service. Follow your model’s manual, pay attention to controller alerts, keep the generator’s airflow clear, and schedule maintenance at the intervals recommended for your equipment.
