"A switch on our circuit breaker panel would not engage, was broken. Through Angie's List, I was able to locate "Smart Home Technologies" who sent a representative out the next day at 9am. "Andy Guthery" arrived as promised on time and quickly diagnosed the issue. Instead of trying to sell us on a whole new panel, he replaced the single switch and explained his reasoning as he did so. He impressed us with his knowledge, skill and sensibility as a worker and as a person. We were well pleased. He had the job done quickly and for a reasonable price. We will be calling on him 'the next time' we need an electrician. So, thank you Angie's List, Smart Home Technologies and Andy Guthrey."

"Service was fast (same day as my call). Daniel and Ryan arrived as scheduled, were professional, and fixed my problem with a toilet back-up, partial component rebuild, a slow drain in the kitchen sink, and even addressed a wish-list item on the spot. They installed an additional water spigot (hose bib) on the southern end of the house. I like the name HERO Services as they were certainly my heroes today! I'm happy to support a business employing veterans. The pricing was reasonable and I am going to stay with them for future plumbing, electrical, or HVAC needs."

"Greg came on schedule and discussed the project with us. He suggested LED pancake lights and dimmer. We originally planned to put in lights on either side of the room. He e-mailed a price by the end of the day. It was a fair price but over our current budget. We really only needed the lights on one side of the room (over the new office area), so I asked Greg to revise the estimate. It was not trouble and he did not try to push me into the original quote. We agreed on the price and he scheduled the work. Brennan came promptly and even texted me when he was close by so I could put the dog in another room. He completed the work very efficiently, cleaned up everything and was just awesome really. Everything is wonderful!!! I have found my electrician from now on!!!"

Always on-time, courteous, cleaned up after his work, and friendly, especially with recommendations to make the job better for us! Highly recommend him as your "go to electrician" for any project."

FAQs for electrical wiring or panel upgrade projects in Loudon, TN

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
