"Jarvis Electric did all of the electric for our new build and has come back to add additional items that we have added since we have been in the home. Super responsive and quick to complete all requested work. Top notch service. Extremely reasonable price. I appreciate that they always keep a clean worksite and never leave a mess, even if coming back the next day to finish a job. I have not only used them for my home but referred them to my mom and dad as well when they needed work done. Great company with great people and really easy to deal with. They truly went above and beyond."

"Ron, our installer, was absolutely wonderful! He arrived on time, was pleasant, and efficient. Ron worked on New Year's Eve, was close to finishing his job, but could have stretched it into the next day. Rather than leaving us "in the dark," he worked until the job was completed that day. We appreciate all the hard work from Ron! We definitely recommend Reinhold for any of your electric needs!"

"CD Electric was fantastic. They added electrical outlets to the interior and exterior of my home and installed an exterior light. Chase was very thorough with the estimate he provided me and completed the job in the time he said it would take. I would definitely hire them again for any future jobs and I highly recommend them to anyone else."

"I was pleased with the installation of the lightning rods--communication was great and the work was done quickly. What I wasn't happy with is he quoted me a price that was less then my actual bill was BUT the price was still less then two other contractors bids."

Electrical FAQs, answered by experts

Black is the standard color for hot wires, which transfer electricity to your outlets and switches. Red wires are also hot wires. White (and sometimes gray) wires are considered neutral, delivering power back to the panel. Finally, green wires, which are sometimes bare copper, are ground wires, used to ground an electrical circuit and prevent electrocution.

According to the National Electrical Code (NEC), GFCI outlets should be installed in wet or damp locations where they might be splashed with water or other liquids. This is to protect against ground faults, which are more common around water. Specific areas that require GFCI outlets include kitchens (especially near counters), bathrooms, laundry rooms, basements, garages, and all outdoor receptacles. Depending on local electrical codes, you may need at least one GFCI outlet in these rooms, or every outlet in the area may need to be GFCI protected.

The number of outlets and lights you can safely run on a single circuit depends on the circuit's amperage and local electrical codes. A general rule is to allow one outlet or light fixture per 1.5 amps, keeping the total load under 80% of the circuit breaker's capacity. For example, a 15-amp circuit can typically support up to eight outlets or lights, while a 20-amp circuit can accommodate up to ten. Always consider the combined power usage of all connected devices and fixtures to prevent overloading. For specific guidelines and to ensure safety, it is best to consult local electrical codes or a licensed electrician.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

The size of your home will help determine the size of your electrical panel. Usually, the decision comes down to a 100-amp electrical panel versus a 200-amp panel. Smaller homes, especially those without an HVAC system, may be able to get by with a 100-amp panel. 

If you have a larger home or need to power AC, a 200-amp panel should be the best fit. It’s unlikely that you’ll need a larger panel than that unless you have a larger home or unique electrical needs, but an electrician can help you make the final call.
