"They did an awesome install and even installed a sound bar and Steven stayed to help debug some Comcast connectivity issues. That was really outside of what he was sent to do but he hung in there until I was able to watch a movie! Also, Bronson helped me find a better value on my TV purchase through them. A+ plus customer service all the way around and everyone was so pleasant to work with. Yes, I probably could have either gotten it cheaper or even had some of my friends help out and install it. But, when they would have finished, I would have been hiring someone else to repair or replace the drywall. Sometimes, you get what you pay for. Would definitely hire them again for future projects! Thanks Bronson and Steven!"

"We purchased an older home with a lot of "do it yourself" electrical panels and alarms. Tym did a thorough review of the home to give his recommendations and then helped clean up everything we agreed was necessary. He was thorough and honest, and the work was completed in one day. Very happy with the results and would highly recommend him and his company."

"Keegan worked three 8-10 hour days, Christian worked two 8-10 days, and Kevin worked one 8 hour day to replace/upgrade two panel boxes, light switches, and outlets in a fifty year old house that has experienced a number of electricians and diy residents over the yearscreating a maze of wires. The job was scheduled for one day but turned into three; Keegan, Christian, and Kevin refused to give up on my house, working through the days with minimal breaks for lunch. I appreciate their hard work, professionalism, and courtesy. I will continue to call GoHero for any work needed."

FAQs for electrical wiring or panel upgrade projects in Maryville, 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.
