"Awesome company! Mike came to my home and gave me a very thorough quote for the work I needed, he was very personable and honest. He was able to schedule my panel upgrade for the next day. Quentin(sp) installed my panel, was very efficient and kind! Also installed two lights in my home, did all of this in about 4 hours! Definitely recommend and will use for future electrical work."

"Chris was a great service man. After a thorough inspection of my power panel, Chris found the problem of power surges and recommended I call ONCOR to fix the service to the house. One phase had burned through the rubber boot. ONCOR promptly came and reconnected the power properly."

"Paul was upfront with all of the work that they were going to do. He communicated very welll and the employee's are dry knowledgeable. They replaced the electrical panel and informed me what I need to do before they could start. All the work went as they said it would. I will use them in the future."

"I have zero complaints about this company. They came out very quickly to access my issue. It was urgent. From Oncor and this company, I clearly escaped what could have been a major fire. These guys were so professional and kept me in the loop of everything being done. I've saved their number for any future issues and I will definitely recommend them to anyone needing a skilled electrician. It was worth every penny to have it done professionally and safely. Thank you ALL."

FAQs for electrical wiring or panel upgrade projects in Sunnyvale, TX

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.
