"I highly recommend First Class Electric. I called this morning and by 10 am Joey the technician was calling me confirming he was on his way. The operator who made the appointment was very friendly and helpful. The technician Joey was very knowledgeable and friendly. He is an asset to your company! He understood what needed to be done and explained his plan. He made sure I was satisfied and answered every question. I will definitely use this company again but I want Joey to be the technician. Thank You!!!"

Electrical questions, answered by experts

No, both switches do not need to be on for a 3-way switch to work. When the two switches are in opposite positions, the circuit is open and the light is off. Flipping either switch closes the circuit and turns the light on. So, either switch can turn the light off independently, and both switches do not need to be in the same position for the switch to function.

Knob and tube wiring is old, and its casing is brittle. This means that it's possible to receive a dangerous electrical shock if you touch a live wire and essentially become an electrical pathway. Although the scenario is unlikely, touching any K&T wiring is simply not a good idea in any instance. Leave any wire handling to the professionals.

An electrician will charge between $100 to $150 to install a new light switch. Whether you need to cut into the wall and repair drywall will determine your final project cost, as you can expect to pay $50 to $75 per square foot to repair drywall.

If half of a string of Christmas lights is out, it is likely because of a single burned-out, loose, or broken bulb within that section. Long strands of lights often contain more than one circuit, so when one bulb fails, it can cause the entire circuit (or half the strand) to go dark. To fix this, inspect the unlit section and test each bulb to ensure it is tight and functioning properly. Replacing the faulty bulb or repairing a damaged shunt will typically solve the problem.

Knowing if and when your circuit breaker is failing or faulty can prevent costly damage. If you notice any of the following signs, call a local electrician to help. 

  • The breaker frequently trips

  • The breaker doesn't stay in the 'on' position or reset properly

  • You hear buzzing or humming noises coming from the breaker

  • There's discoloration around the breaker switch

  • There's a burning smell or visible signs of damage on the breaker
