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 does my standby generator need professional maintenance?
Most manufacturers require annual maintenance to keep warranties valid. We recommend service every 12 months or after 200 hours of runtime. Whichever comes first. If you have frequent power outages, get twice-yearly inspections. This catches wear issues before they cause failures during emergencies.
We change the oil and filter. We inspect spark plugs. We test the battery and charging system. We verify proper fuel delivery. We exercise the unit under load. We test the automatic transfer switch operation. We check all electrical connections. We review error codes from the controller. The visit takes 90 minutes to two hours.
Basic tasks like keeping the area clear are fine for homeowners. Checking for visible damage is okay. However, testing transfer switch operation requires proper equipment. Measuring voltage output needs training. Checking natural gas pressure regulators is technical work. Interpreting fault codes requires expertise. Improper maintenance voids warranties and creates dangerous backfeeding risks.
Dead or weak batteries are the top cause of generator failure. We frequently find deteriorated fuel in propane systems with regulators. Corroded electrical connections are common. Mice nests block cooling airflow. Transfer switch contacts become pitted over time. They prevent proper switching. Regular inspections catch these issues before they leave you without power.
We maintain most major residential brands. These include Generac, Kohler, Briggs & Stratton, and Cummins units from 7kW to 48kW. Our technicians carry diagnostic software for controller systems. We stock common wear parts. If your unit requires specialized factory tools, we coordinate directly with manufacturer support to complete the service properly.

A service visit costs far less than emergency repairs during a winter storm. We routinely find issues like weak batteries or clogged air filters. These would cause startup failure when you need power most. Generator repairs during outages cost much more due to emergency rates. Parts availability becomes limited when storms affect entire regions. Prevention saves money.
