They have added additional lighting for several tenants and after we replaced the roof they added the exterior lighting to really brighten up the surroundings of the building for greater security and visibility all with led lights for energy efficiency.

"Too bad I had to give them even 1 star. Mr. Sparky will find the absolute most expensive test and diagnostics to run for the simplest issue. Jeremy took advantage of a stressed out woman who simply had an arcing outlet and charged over $1100 to replace it and tighten connections in 2 outlets on the same circuit. Jeremy logged over 2 hours on the job per the owner, while spending hardly over an hour. Half of which was spent writing a quote for $8000 worth of work while enjoying and laughing at the tv in the background. Jeremy was lingering inside and outside the house after the work was complete. Upon speaking to the owner, the owner made personal attacks against myself and my wife. The owner proceeded to tell me that I should have been at home taking care of my family rather than being at work. Terrible company with terrible leadership. They will respond and say I was treating them poorly. At the end of the day they have to pay for their cookie cutter business by over charging ALOT."

"I wanted a portable generator and RV hookup for my house. In order to do so, I needed a larger panel with more space to accommodate the new circuits and the lockout switch. Ramon did a great job on the installation, and I now have everything I need to hook the generator to the house or hook up the RV."

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

HVAC systems consume the largest portion of household electricity, as they operate frequently throughout the year. Water heaters represent another significant energy user in most homes, along with refrigerators that run continuously. Clothes dryers, dishwashers, and cooking appliances also contribute substantially to electricity usage. Entertainment systems, particularly those left in standby mode, can collectively add meaningful amounts to monthly bills.

Time-of-use electricity plans charge different rates depending on when you use power. Peak hours—typically weekday afternoons and evenings—come with premium rates, while overnight and weekend hours often feature discounted pricing. Households that can shift major electricity usage to off-peak hours may benefit from these plans. The effectiveness depends on your schedule flexibility and ability to run major appliances during lower-rate periods.

Solar power systems represent a significant investment, currently averaging between $18,115 and $35,165 for residential installations. The financial benefit varies based on your location's sun exposure, local electricity rates, and available incentives. Homes with consistently high electricity bills see better returns on solar investments. Many homeowners consider both immediate savings and property value enhancement when evaluating solar options. Contact solar panel installers near you to discuss the potential costs and benefits for your home.
