Why Regular Generator Service Matters

Your standby generator sits idle most of the year, but it needs to fire up instantly when the power goes out. We inspect your unit twice a year, checking oil levels, testing the automatic transfer switch, and running a full load bank test to verify your system can handle your home’s actual electrical demand. Our technicians catch small problems before they become expensive failures during a storm.

Expert Technicians

What We Check During Every Service Visit

We test your generator under load, verify the 200-amp transfer switch operates correctly, and inspect all electrical connections for corrosion or looseness. Our service includes changing the oil and air filter, checking battery voltage, and confirming your natural gas or propane supply line has proper pressure.

Common Questions

Residential Electrical FAQs

Common questions from Triangle homeowners about residential electrical services. Don’t see yours? Call us directly — we’re happy to help.
How often should my home generator be serviced?
We recommend service every six months or after 200 hours of runtime, whichever comes first. Most homeowners choose our annual plan with spring and fall visits. We change the oil, test the battery, inspect the transfer switch, and run the unit under load to verify it can handle your home’s power needs.
Generators that sit without service often fail when you need them most. Oil breaks down, batteries lose charge, and fuel systems develop varnish buildup. We’ve seen units refuse to start during outages because a simple battery replacement was overlooked. Regular maintenance costs far less than emergency repairs during a storm.
Yes, we work on Generac, Kohler, Briggs & Stratton, Cummins, and most major brands. Our technicians are factory trained and carry diagnostic tools specific to each manufacturer. We stock common filters and parts on our trucks so most routine service is completed in one visit without waiting for shipments.
Our plan includes two complete maintenance visits per year. We change oil and filters, test the battery and charging system, inspect all electrical connections, verify transfer switch operation, check for fault codes, and run a load test. You also get priority scheduling if your generator fails to start during an outage.
Absolutely. We perform load testing during service visits to verify your generator produces the rated kilowatts and can handle your actual home load. If your transfer switch is set up for whole-house coverage, we confirm the amperage capacity matches your main panel and check that critical circuits receive power first.

Our plans include priority response for emergency service calls, meaning we move you to the front of the queue during outages. Parts and labor for repairs are billed separately, but plan members receive discounted rates. We stock common repair parts and aim to restore your generator the same day whenever possible.
