"Jay was able to come early which worked for us. He assessed the problem with the leaking valve, offered 2 solutions with clear pricing and clear reasoning as to why he recommended the slightly more expensive one (much less likely to fail in the future!). He accomplished the work quickly, showed me the completed work, and showed me why the other valve had failed, AND the area was clean and dry when he was done. Throughout the visit he was pleasant, polite and respectful. Will be happy to use this company again!!!"

Electrical questions, answered by experts

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

An electrical fire can start even if nothing is plugged into the outlet. Fires can be caused by faulty wiring, damaged outlet components, or other electrical problems hidden behind the walls. At the first sign of an electrical problem, shut off the breaker and contact an electrician to diagnose and repair the issue.

There are a few telltale signs that it’s time for a replacement. You should consider an upgrade if:

  • Your panel is over 25 years old

  • You’re adding a new electrical system

  • Your current system doesn’t offer the power you need

  • Your home is a jungle of power strips

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

Modern homes have a lot of devices and appliances running at once. That means there are many different wires and cables throughout the house. Service entrance conductors (also known as service entrance cables or service feed wires) connect the external weatherhead for the utility pole to the circuit breaker box. This is your home’s connection to your local power grid.
