Questions and Answers

What is included in a professional electrical inspection from Hartwig Engineering?

Our electrical inspection is a thorough evaluation conducted by a registered professional engineer. We assess your entire electrical system's safety and code compliance, checking wiring, panels, outlets, and grounding. For Goodyear residents, we pay special attention to local concerns like arc fault circuit interrupter (AFCI) performance and the condition of conduits that may be affected by soil movement, providing you with a detailed, actionable report.

Why do my arc fault breakers in Goodyear keep tripping, and how can you help?

Frequent AFCI trips in our area are often caused by a combination of factors, including older wiring, the specific demands of modern appliances, and connections stressed by thermal expansion in our desert climate. With our engineering background in system design and diagnostics, we don't just reset the breaker. We methodically trace the circuit to identify the root cause—whether it's a wiring fault, a compatible device issue, or a need for a dedicated circuit—and provide a lasting solution that prioritizes your home's safety.

As a professional engineer, how is your approach different from a standard electrician?

Our foundation is in engineering design and construction administration for major projects. This means we bring a systems-level perspective to every job, whether it's an inspection or a repair. We understand not just how to fix an immediate problem, like damaged conduit from soil shift, but also how that component fits into and affects the overall performance and safety of your property's electrical system. This depth of analysis is particularly valuable for renovations, updates, and ensuring long-term reliability.
