Questions and Answers
My breaker keeps tripping in my Keller home. What could be causing this, and can you fix it?
Frequent breaker trips, especially with modern Arc Fault Circuit Interrupters (AFCIs), are a common issue in Keller homes and can signal overloaded circuits, faulty appliances, or wiring problems. As a licensed contractor with over 25 years in DFW, we start with a thorough safety inspection to diagnose the root cause—whether it's an overloaded kitchen circuit or a more serious arc fault. We then provide a clear repair plan, which may involve circuit breaker repair, panel upgrades, or dedicated outlet installation to safely distribute power and prevent future trips, ensuring your system is up to current code.
What's involved in upgrading an old electrical panel, and why is it important?
Upgrading an electrical panel is crucial for safety and capacity, especially in older homes that may not support modern appliances, HVAC systems, or EV chargers. Our process begins with a detailed assessment of your home's current and future power needs. As master electricians, we handle the entire installation—from safely disconnecting the old panel to installing a new, code-compliant unit with proper labeling and surge protection. This upgrade enhances safety by reducing fire risk, prevents frequent breaker trips, and provides a reliable foundation for any additional electrical projects you have in mind.
Do you offer electrical inspections for home buyers or sellers in the DFW area?
Absolutely. Our comprehensive electrical inspections are a valuable service for both home buyers and sellers in Keller and the greater DFW area. With our 25 years of local experience and BBB accreditation, we provide a detailed, unbiased evaluation of a property's electrical system. We check for code compliance, safety hazards like overheated outlets, panel condition, wiring integrity, and the functionality of GFCIs and AFCIs. You'll receive a clear report that can inform purchase decisions, negotiations, or necessary repairs, giving you peace of mind about one of your home's most critical systems.
