"Lowest price among multiple quotes and significantly more attention to detail and the least visible and least intrusive installation of new wiring from the existing panel. Would definitely recommend and use Mark H. Anderson Electrical Services again!"

"Ash Electric installed a level 2 Tesla charger for us. We went with Ash as their quote was very reasonable. From the beginning, it was clear that customer service and communication were both excellent. Noah kept me informed at every step and was honest and prompt with responses. Even when he was away from home, he kept in touch. Installation was done by Vince who was extremely professional and did the job perfectly and in a reasonable time. Inspection was scheduled by Noah and went through quite easily. I would say Ash Electric went above and beyond what was required to satisfy a customer. Most companies could learn a thing or two from them. If you are planning on installing a charger, look no further. I would highly recommend them to anyone."

"I had a wonderful experience with Electrical Connections. My project ended up being much larger than I anticipated it would be and they were excellent at explaining everything and helping me understand what needed to be done. Customer service was top notch and clearly a priority for everyone I talked to from the scheduler to the owner of the company. Brian was excellent and stayed until the job was done even though it made an extra long day for him. Highly recommended!"

Customers say: Quality work

"From start to finish, Long Electric had our backs. We didn't have to hire sub-contractors or to obtain permits -- Long Electric took care of everything. Our go-to person in the main office, Melissa, answered all of our questions and kept us apprised of everything we needed to know. Everyone we had contact with throughout the installation project treated us with the utmost in professionalism. Not only will I call upon them for future electrical needs, I have referred Long Electric to a friend who is also interested in a whole house generator."

Electrical questions, answered by experts

Durations range from an hour for simple jobs to full workdays for significant upgrades.

No, it’s not normal. When an outlet is hot, something is wrong. Our tips above may help you pinpoint the problem, but when in doubt, always bring in a qualified electrician to deal with the issue. 

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

Upgrading a two-prong outlet to a three-prong outlet typically costs between $20 and $50 per outlet if the electrical box is already grounded. However, the cost can increase significantly if the system is not grounded, as this may require grounding the box or upgrading your electrical panel. Electricians generally charge between $50 and $100 per hour for labor, and the total cost for a more complex installation could range from $130 to $300.
