Preventive Care

Regular Maintenance Prevents Costly Failures

We inspect your standby generator every season to catch problems before they leave you without power. Our technicians check oil levels, test the battery, verify the automatic transfer switch operates correctly, and run load bank tests to confirm your unit delivers its rated output. Most generator failures happen because of skipped maintenance, not age.

Common questions from Triangle homeowners about residential electrical services. Don’t see yours? Call us directly — we’re happy to help.
How often does my generator need maintenance?
Most manufacturers recommend service every six months or after 200 hours of operation, whichever comes first. We check oil and filters, test the battery and charger, inspect belts and hoses, and run the unit under load. Natural gas generators typically need less frequent service than diesel or propane models due to cleaner combustion.
We start with a visual inspection of the entire system, then change the oil and filters. We test the battery voltage and charging system, verify the transfer switch trips correctly, and run the generator at full load for at least 30 minutes. We also check all electrical connections and look for any error codes in the controller.
The most common causes are dead batteries, old fuel, or a tripped breaker in the transfer switch. We see a lot of units that run fine during monthly tests but fail during actual outages because the battery can’t handle sustained cranking. Low oil pressure switches and faulty ignition modules are other frequent culprits we identify during service calls.
Yes, we maintain any residential standby generator regardless of who installed it. We bring factory service manuals and diagnostic software for all major brands. During the first visit, we document your system specifications, verify proper installation per current codes, and create a maintenance record for future reference.
That depends on your total electrical load and which circuits you want backed up. Most homes use either a 200 amp whole house switch or a 100 amp partial panel. We perform a load calculation based on your main breaker size, essential circuits, and largest motor loads like air conditioners or well pumps to size it correctly.

We provide 24/7 emergency service for generator failures during outages. Our trucks carry common replacement parts like voltage regulators, control boards, and fuel solenoids. If your unit won’t start or stops running during a storm, we prioritize those calls and typically arrive within two to four hours depending on your location and weather conditions.
