"I hired Heeren Electric to provide power down to the basement. Frank responded quickly and was able to set up a time. He came out for a free quote. He is very personable and professional. I definitely felt comfortable with him in my house. He did an awesome job and was very thorough. He also gave me a lot of pointers for my DIY. He also offered me a military discount which was greatly appreciated. I highly recommend him and would not hesitate to hire them again."

"Rick was knowledgeable and educated me when n my electric panel. I have old wiring and was tripping my circuit breaker. He found an ingenious solution. Definitely thought outside the box for a great, cost efficient solution that was timely. He was very thorough in his diagnosis and efficient in his solution. I would have him come back anytime I need any electrical assistance."

Electrical FAQs, answered by experts

Unless you’re a licensed electrician with extensive experience in upgrading electric panels, you must hire a professional for any electrical work. A licensed electrician will make sure your breaker is upgraded safely and in compliance with local codes. Your pro will also take care of any permits and inspections that are needed.

Amps describe the amount of energy that can flow through a circuit breaker. Every electrical device that’s attached to the breaker requires about 1.5 amps. While that equates to roughly 13 receptacles per 20 amps, using slightly fewer ensures that your circuit will always have enough energy for sudden power surges instead of tripping when one occurs. In general, 10 to 12 receptacles is recommended for a 20 amp circuit.

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.

Incandescent lights are glass bulbs with metallic filaments inside, while LEDs feature “light emitting diodes” that illuminate when they come in contact with an electrical current. You can buy either for your Christmas lights, but note that LED lights are more energy-efficient and have a longer lifespan.

Motion sensors are actually an eco-friendly option and don’t use as much electricity compared to other lighting sources. Motion sensor lights are always on “standby,” which requires a phantom source of power at all times, but for most sensor light models, this is only a small amount of electricity—typically around one watt of power.
