McHenry Electric & Supply Co - McHenry's Emergency Electricians

Our comprehensive electrical inspection includes testing your home's grounding system, evaluating the condition of your wiring, and assessing your existing surge protection. We can identify if your electrical panel or circuits are vulnerable to surges that can damage expensive appliances. Based on our findings, we often recommend and install whole-house surge protectors, which act as a first line of defense, diverting excess voltage before it reaches your sensitive electronics.

Signs of a damaged underground cable include frequent, unexplained circuit breaker trips, flickering lights especially during wet weather, a burning smell near the ground or foundation, or a partial loss of power in your home. Given the age of some infrastructure in our area, these issues can develop over time. If you notice any of these symptoms, it's crucial to call us for an inspection. We can safely diagnose the problem and perform the necessary trenching and cable replacement to restore safe, reliable service.

We strongly recommend an inspection first. Simply replacing the appliance doesn't address the root cause. The surge that damaged one appliance indicates a vulnerability that could affect all your electronics. Our inspection will determine if the surge was a one-time external event or a symptom of faulty home wiring, inadequate grounding, or lack of proper surge protection. Fixing the underlying issue protects your new appliance and your entire home's electrical system from future damage.
