"Arete’s team was incredibly professional and efficient. They completed my HVAC job in a timely manner and beat competitor’s pricing. Their team was very respectful of my home and even wiped the floor after each day’s work. Every member of the team was kind and respectful. Will certainly work with them again in the future for any of my HVAC/electrical needs."

"Dave was great! Top quality work at a fair price. I needed a degraded riser cable that feeds the meter box outside the house replaced. Another company gave me a ridiculous quite which included current code updates that said I needed. My town electrical inspector said that none of those were required for a simple riser cable replacement. I highly recommend Lanzillo Electric!"

Electrical questions, answered by experts

A standard three-prong electrical outlet typically lasts for about 15 years with normal use and should be replaced accordingly. GFCI outlets may have a longer lifespan of 15 to 25 years. While some outlets can last longer if used infrequently, they can also fail prematurely. Reasons for early failure include poor wiring, an overloaded circuit, improper grounding or installation, or loose plugs. Signs that an outlet is failing include flickering lights, overheating, a discolored or melted faceplate, plugs that fall out easily, or frequently tripping circuit breakers. It is essential to address faulty outlets promptly to avoid safety hazards, especially in homes older than 15 years.

When converting a standard 120-volt outlet to a 240-volt outlet, the only components you can typically reuse are the existing electrical box and the hole in the wall. Everything else—including the wiring, breaker, and receptacle—should be replaced to ensure both safety and efficiency. Appliances designed for 240 volts have different plug configurations that won’t fit into a standard 120-volt outlet, making it necessary to install a compatible 240-volt receptacle. This design helps prevent overloading or underloading the power available to any one outlet or circuit.

The average lifespan of a home electrical system is anywhere from 30 to 70 years or more, depending on the type of system you have. Modern electrical wiring, like aluminum or copper, can last 50 to 70 years while older types may need to be replaced sooner. Additionally, circuit breakers tend to last anywhere from 30 to 40 years, while electrical outlets need to be replaced every 10 to 25 years. 

It's less expensive to run power overhead because it doesn’t require excavation, and the power cables are less costly. However, underground electric service is better protected from weather and general wear and tear, so it’s less likely to get damaged. When determining which way to run power, consult a local electrician to get an expect opinion.

The National Fire Protection Association reports that almost half of reported electrical fires are caused by electrical distribution and lighting equipment. The main culprit behind these fires is often frayed, worn, or faulty wiring, particularly in closed-off and concealed areas like attics, where fires can start and burn undetected for long periods.
