Job Locations and Reviews
Replaced breaker with a standard breaker Installed a GFCI outlet in upstairs hallway
Troubleshoot Pool light
Replaced faulty flood light
Troubleshoot electrical issue. ISSUE: lights not working LOCATION: upstairs FINDINGS:lights upstairs were not functioning. Some led lights would come on very dimly. It appeared to be a neutral issue. During my diagnosis I noticed a bundle of neutral wires in the toilet room of the master bathroom. It appeared to be a proper splice, but when I undid the splice a piece of copper fell off. The neutral wire had been improperly spliced at original installation and over time broke off causing the rest of the circuit to lose the neutral. All switches and outlets on the circuit were also backstabbed RESOLUTION: I remade the splice and everything functioned as intended. I informed the customer of my findings and recommended to replace all devices and remake all connections on the affected circuit Replace all outlets and switches on master bath/laundry circuit and remake all connections in junction boxes on that circuit
Performed 1 system diagnostic for the system that serves the whole home. Found dirty filter, dirty condenser, failed capacitor, duct work not properly sized and falling parts, plenums are not sealed. Customer opted for replacing the capacitor only. Also recommended IAQ products due to growth on the plenums The bare minimum basic repairs to get the system running today.
Performed leak search on garage ceiling. Cut several holes when arrived water was off. Turned on water to see if it was an active leak. After (2)+ hours no leaks occurred from water lines. Ran water down drain out of all bathroom group fixtures, filled bowls flushed toilets ran showers no leaks could be recreated. The water damage in the ceiling runs with the ac duct lines. It follows its path. And one of the duct lines has water inside of the line. No leaks found
Troubleshoot dining room outlets
Backfilled the hole by the meter and put new concrete in the hole in the garage.
I came out to install cat 6 ethernet cable from the basement up through two floors and over to the front office bedroom. I pulled three lines and labeled each one as well as putting ends on each one and giving you an easy access port for them. I am also giving you a price for installing a disconnect for a mini split in case you decide to go forward with that. Last you do have a challenger panel and you should get that replaced. Challenger panels have a bad history of failing when the breaker should trip and this is something you can research on your own. I’m giving you a price for replacing that panel as well as bringing your house up to code, including installing wired smoke detectors in each bedroom. Thank you for using TE certified electrical!

Came out today for a failed hose bibb after the handle broke off when the customer attempted to turn it. Replaced the hose bibb and secured it to the homes structure. Inside, removed the existing gate valve and installed a lever-handle shutoff valve for easier isolation during the winter months. Advised the customer to winterize all outdoor fixtures to help prevent freezing and burst pipes. Tested all completed work for leaks and proper operation. Everything is working properly at this time.

For this job, we worked on replacing a faulty GFCI by the front door along with a new bubble cover. replaced a bubble cover on the side of the home for a wider, single gang one so both plugs can fit. We had to troubleshoot to figure out why charger was overheating, it turns out that the installer put the charger on a 30 amp breaker so we switched it to a 50. after doing a test charge, the overheating message he always receives did not pop up. also confirmed that there is a short in her landscape circuit leaving the transformer so I left a quote to replace the 10 year old fixtures to pinpoint where the issue is.
Responded to a squealing toilet on the second floor. The customer stated the noise began when the toilet was used after sitting unused for several months. Tested the homes water pressure, which was holding at 55 psi. Completed a minor toilet rebuild, replacing the fill valve, flapper, and supply line. Tested the toilet after repairs and confirmed it is functioning properly with no squealing or leaks.
Pulled and reset toilet and replaced flange
Came out today to investigate a high water bill. We began by shutting off the homes interior main water valve located in the basement and inspected the water meter. With the water shut off to the home, the meter was not spinning, indicating no active water loss between the meter and the home. We then restored water to the home and inspected all accessible plumbing fixtures for leaks or dripping. No active leaks were found. With all fixtures turned off, we rechecked the water meter and confirmed that it was still not spinning, indicating no active water usage at the time of todays inspection. We also inspected the water heater, including the temperature and pressure relief valve, for any signs of water loss and found no active leaking. Based on todays inspection, we were unable to identify an active plumbing leak that would account for the reported high water bill. The customer will contact the water utility to have the meter and billing reviewed for possible inaccuracies.
Delete sub panel and move everything into new main QO electrical panel with safety breakers

Thank you, Drew, for the kind words and 5 stars. We are so glad Johnny could answer after hours and take care of your emergency. Your recommendation means a lot to our team at TE Certified. We appreciate you taking the time to share your experience.
Excellent service
I had a few electrical issues that Chase went above and beyond to help me with. From the beginning, he was professional, thorough, and took the time to explain what was going on rather than just telling me what needed to be done. He provided me with several options, explained the pros and cons of each, and gave me his recommendation along with the reasoning behind it. I really appreciated that he gave me the information I needed to make an informed decision without feeling pressured. The price was fair and the work was done properly. Its not often you come across someone who combines good workmanship with honesty, transparency, and genuine customer service. I would definitely recommend Chase to anyone who needs electrical work. He earned my trust and I wouldnt hesitate to call him again.
Steve, thank you for the thoughtful review and 5 stars. We are thrilled to hear that Chase was professional, thorough, and clear in explaining options and pricing. Earning your trust through transparency and quality workmanship is exactly what we aim for at TE Certified. We appreciate your recommendation and the time you took to share your experience. We will share your kind words with Chase.
Jonathan was an exceptional technician. We felt informed and confident in his work. He got right to work and was very professional. Thank you for making a tough situation better to deal with.
Mauricio arrived right on time for our appointment and kept us informed about his arrival, which we really appreciated. He was incredibly professional, courteous, and knowledgeable throughout the entire visit. After the recent storms, my husband and I needed an electrician, and we couldn’t have been happier with the service we received. We had such a positive experience and would highly recommend this company to anyone looking for reliable, professional service. We will definitely be using them for all of our future home needs, including plumbing, air conditioning, and electrical work. Thank you, Mauricio, for making the whole experience so easy and stress-free!
Always great customer service, thorough evaluations, patient option walk-thru, and just down-to-earth people!

Nathan came out and was extremely professional and kind. I was informed all along about their arrival time and they were right on. I had an odd smell problem and Nathan and his co-worker checked everything out for me. They were very patient and nice. Highly recommend.
Carol, thank you for the thoughtful review and 5 stars. We are glad Nathan and his coworker were professional, kind, and patient. It is great to hear our updates kept you informed and on time. Finding the source of an odd smell can be tricky, so we are happy they checked everything carefully. Your high recommendation means a lot to our team at TE Certified.
Very disappointing experience. I paid $149 for a diagnostic visit, but the electrician was unable to identify the actual cause of the problem. The explanation provided for the possible cause did not make ANY sense and did not address the issue I reported. I hired a professional electrician specifically to properly troubleshoot, diagnose, and identify the cause, but I received no clear diagnosis or solution. I feel I simply wasted $149 on a service that did not provide any useful result. I would not recommend this company based on my experience.
I had an exterior plumbing leak right next to my water meter box, so I called TE Certified. They sent out Martin, and he provided the best experience and customer service I could have asked for from start to finish. Martin was a true professional who wasn't afraid to get his hands dirty to properly diagnose the issue. What stood out during his initial visit was how detailed and knowledgeable he washe accurately diagnosed the leak, walked me through the exact repair plan, and gave a price that was easily the most reasonable given his expertise and care. About five days after getting quotes from other plumbers, I knew without hesitation that I wanted to go with TE Certified and have Martin handle the job. Today, he came back and accomplished the entire repair in just two hours, leaving the site with the same level of respect, thoroughness, and care I experienced on day one. Someone with that level of honesty, skill, and dedication to helping customers speaks volumes about their character and passion for their work. Moving forward, TE Certified is my go-to, and Ill definitely be asking for Martin every time. Highly recommended!
Jose was prompt in arriving. Very professional greeting. Listened carefully to my explanation of the issue. Assessment ogf the issue was through
I got the Sump pump replaced and Ben was confident of the issue from the get go. He was thorough about the process and did a fantastic job. He got the work done today and I am happy. Hope I do not have to call him back again for the same issue.
Kaushik, thank you for the 5 stars and for sharing your experience. We’re glad Ben quickly identified the issue and explained the process. It’s great to hear the sump pump replacement went smoothly. Your kind words mean a lot to our team at TE Certified.
