"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

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. 

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 doorbell installation cost depends on which and how many parts you need to replace. A new transformer is the least expensive replacement and falls between $20 and $35, plus the cost of hiring an electrician to install it, which can be between $150 and $250. Replacing your entire doorbell system can cost $250 to $400.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

Local building codes typically require conduit around exterior wiring. Conduit protects the wire from moisture, extreme temperatures, sun exposure, and harsh weather conditions to prolong its lifespan. When a wire is worn out, it can be dangerous as the risk of electric shock or fire increases.
