Electrical questions, answered by experts

Systems should be checked every 2-3 years or whenever signs of age appear, maintaining network integrity and safety at all times.

Upgrading your electrical panel is often worth the cost for safety, improved electrical performance, and potential long-term savings. A primary benefit is preventing electrical fires and other hazards from a malfunctioning panel, ensuring your household's safety. An upgraded panel also provides a steady flow of electricity, eliminating issues like flickering lights and frequently tripped breakers. It allows you to connect additional appliances without overloading the system, which is especially beneficial for older homes with 100-amp service that are prone to overheating. If you run large appliances like central air conditioning, heating systems, hot tubs, or saunas, you might consider upgrading to a 300- or 400-amp service to meet the higher electrical demand. Furthermore, an upgrade can lead to long-term savings on energy bills and potentially lower insurance costs.

On average, the cost to wire a new home ranges from $2 to $5 per square foot. The cost to rewire a house is around the same, ranging from $2 to $4 per square foot. Often, though, new wiring comes with lower overall costs since it’s much easier to access a home’s foundation. 

Schedule regular inspections, clean fixtures, and replace worn-out components promptly.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours.
