"Had an electrician out to give me an estimate on replacing my electrical panel. Decided against replacing it because that wouldn't have solved my issue. My house was built in the 60's so it needs all new wiring. I just had him show me which outlets were on each of the channels so that I could spread out my devices that needed a lot of power, specifically my space heaters."

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"I live in the valley six months and East Coast 6 months. I have used Hegge three times. In 2005, Jose Santos replace 2 kitchen fluorescents with 6 recessed cans and then put in 4 additional recessed cans with its own dimmer in eating area where there had been only a fan with a bad light. In 2011, Francisco Montano put in an additional recessed can in a dimly lit closet. On 1/18/18, Francisco repaired loose wiring leading to a frequently tripping GFCI and corrected a blown circuit with a GFCI. These guys are expert, quick, neat, friendly, and prices are so reasonable for what they do. They are so neat that when they are done, you can't tell that what was new was not there before. Hegge goes out of its way to accommodate your schedule. I wish I had a Hegge for everything, not just electrical. The price quoted was just for the last service"

"

Mr. Dove didn't do the work.  It was two of his employees or subcontractors.  The installation of the wiring, ceiling fan and ceiling light went fine, but the drywall repair wasn't that good.  The texture they sprayed on the walls didn't even remotely match the existing wall texture, so their patch job was obvious.  Also, they didn't reconnect something in one of the outlets so only the top socket worked.  When I notified Mr. Dove, he came out the next day to fix it.  I was impressed by Mr. Dove's professionalism, and would hire him again provided he did the work.

"Came out on a Sunday to provide an estimate for a panel upgrade.  Very friendly and knowledgeable about his trade.  While we ended up going with a different contractor, we will definitely have them bid on some electrical work in a few months when we start our remodel.  Highly recommended!

FAQs for electrical wiring or panel upgrade projects in Thermal, CA

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.
