"We needed to upgrade the electrical in our mobile home and add power to our garage/shop. I called ASE and spoke to Art. He was able to come out that day and give a bid. Also met me at my son's house later that day to check out an electrical issue. Bids were very acceptable and work was scheduled. Work at my son's was done a couple days later. I requested a later date due to prep work and 2 electricians arrived right on time. I had all new receptacles installed, ran 3 new circuits (AC, extra hot water tank and split a previous circuit), wiring ran for new ceiling lights, rerouting old wiring and neatening wires from a wall removal. Our little garage/shop had only 1 available receptacle for everything (freezer, lights, etc). Now we have 16 receptacles for 110 and a drop cord for 220. We are so happy! Equipment that has been sitting for years can now be used and no more blowing a breaker if too many amps are used. In the house I can plug in the vacuum without having to crawl under the table or move something to get to a receptacle. Art, Jerron and Hayden were great to work with. They all listened to us, made suggestions and accomplished everything we needed. Highly recommend!!!!!"

"I called and asked them to come in and install some new light fixtures, right off the bat they were really polite. They came in the very next day, got the job done fast and did a beautiful job. Will be calling again if I need any other electrical work. Amazing workers and outstanding customer service."

"John and Brian were prompt, professional, and had the work done in good time. They obviously work well together and enjoy their work. They gave me exactly what I wanted and didn't try to hard sell me something I didn't need. I would recommend definitely them, in fact I already have! Next time I need electrical work done, I am probably not going to even get bids, I will just call Greener Futures."

"Derek was easy to communicate with, arrived right on time, worked efficiently, and was respectful of me and my home. He made sure I liked how the pendant light was hung, and adjusted the height when we agreed it was too low. He recommended and quickly completed a small amount of additional work in the guest room that will save me future headaches. I love that MasPro is a small family business too… I would absolutely hire again for any future electrical or plumbing work."

"I basically lucked out when I found North By Northwest on Anji's List. Troy is very knowledgeable and professional, and my husband and I felt very comfortable in having him take on the project. He completed the job in a most timely manner. Another benefit is knowing that we now have a most reliable electrician to call for other electrical issues."

"Summit Electrical's 2 employees (one journeyman, one aprentice) were prompt, they were clean and well groomed and they brought in a vacuum and a broom! The work was not easy and they had to make adjustments which they did. The job was done very well and they cleaned up the work area nicely. We are very happy with the overall experience: We highly recommend them. Thank you."

Electrical FAQs, answered by experts

No, it doesn’t matter which of the two wires goes on each of the two switch terminals. Just be sure to put the ground wire in the correct terminal. The ground wire is either green, bare copper, or green with a yellow stripe. The other wires are hot wires and are typically black. They can be used interchangeably.

Many homes have a 200-amp service, which requires a 2-inch electrical meter riser. Larger homes or homes that require more energy for several appliances and devices may have a 400-amp service. For 400-amp service, opt for a 4-inch electrical meter riser.

The best place to put an electrical outlet depends on your needs. A good rule of thumb is to install outlets every 6 feet in large rooms. Hallways over 10 feet long need one electrical outlet minimum. 

If you find yourself needing extra plug-ins for all of your gadgets, you may want to increase the number of electrical outlets in your room. When adding outlets, keep in mind that older homes could have outdated electrical panels. In these cases, you may need a pro to upgrade you from 100-amp to 200-amp service before increasing the power load.

Incorrectly wiring a single-pole switch results in the connected light or device not turning on or tripping the circuit breaker. Although it doesn't matter which terminal the hot wire and the load wire connect to, mixing up a circuit wire with a ground or having loose connections can prevent the switch from working. 

If you’re interested in exploring other avenues to completely upgrade your electrical panel, it’s also possible to add a sub-panel, which is a smaller panel that connects to what you currently have in place. This way, you can add additional circuits without having to swap out your main panel.
