"First time residential customer here. I had a fantastic experience with Mr. Electric of Houston Midtown, specifically with electricians Franklin and Zack. Franklin was very professional, polite and knowledgeable, he evaluated my situation, advising me of my options and a competitive quote. We agreed and he got right to work with Zack the following Monday. Franklin and Zack were both very polite, professional, meticulous and clearly they take pride in their work. Since there were several new light fixtures being installed, they both communicated clearly and timely to make sure that the fixtures, switches get installed in the preferred locations. Wiring and overall fixtures alignment was perfect. Breaker box is also now up to code with surge protector and grounding wire which was missing. The job was done with such care and expertise that the benefits truly outweigh the cost. It's a worthwhile investment for the betterment and safety of my home. I highly recommend their services! I will definitely use them as my electric company from now on."

"William, the Technician was very professional and discovered the problem right away. Then informed me that he would perform a safety check on all the electrical connections in the electrical panel free as part of the agreed on pricing. This was a really good experience and would highly recommend Mr Electric North West to anyone who need electrical help!"

"I recently had a subpanel and generator interlock kit installed at my home, and I couldn’t be happier with the experience. From start to finish, they were professional in every way. The quote was accurate and fair with no surprises, and they got me on the schedule much quicker than I expected. They arrived promptly, communicated clearly throughout the process, and completed the work efficiently in a short amount of time. The installation looks great and everything works exactly as it should. I would absolutely recommend them to anyone needing electrical work done."

"Oscar Rosales of Right Pro Electrical Services was very professional, knowledgeable of the type of service we needed and was very organized while doing the job. We needed our portable generator installed using our natural gas hookup; he also organized our electrical system to handle the electrical service we will need in the event of a power outage. He walked us through each procedure needed for start up and shut down; in addition to giving us written instructions of each step of the way. We would most certainly recommend Right Pro Electrical Services!"

"I only gave 4 stars because it was expensive, but I don't know if it was any more expensive than any other electrician would have been. Otherwise, they were great -- on time, courteous, professional...."

"We used Angi.com to find an electrician to install an EV charger we bought for our new EV. Sear Electric responded quickly, came out to complete a visual review of what was needed and they produced a very reasonable quote for the installation of the charger in our garage. The employees were very communicative, friendly and professional, and the overall quality of work was excellent. The guys who did the installation were also very patient as I made sure I got the app connected and verified the charger would indeed charge the car. We are pleased with the work Sear Electric did and would hire them again if we have any other electrical issues or projects."

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

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
