Questions and Answers

My generator in Jarrell isn't powering my house during an outage. What could be wrong?

This is a common issue we see locally, often related to the generator's transfer switch. The switch might be faulty, incorrectly installed, or not communicating with your home's electrical panel. Our technicians can inspect, repair, or professionally install a new transfer switch to ensure your generator seamlessly and safely takes over when the grid power fails.

How can I tell if my Jarrell home has improper grounding, and why is it a problem?

Signs can include frequent breaker trips, tingling sensations from appliances, or non-functional outlets. Improper grounding is a serious safety hazard, especially in our area, as it leaves your home vulnerable to electrical surges (like from storms) and increases the risk of shock or fire. We perform thorough electrical inspections to test your grounding system and can repair or upgrade it to current safety standards.

I'm installing a standby generator. Do I need an electrical panel upgrade as well?

Often, yes. Adding a generator, especially a whole-house unit, places a new demand on your electrical system. Your existing panel may not have the capacity or the correct breaker spaces to handle the backup circuits safely. We can assess your current panel during our generator installation service and recommend if an upgrade or sub-panel is necessary for safe, reliable operation.
