Customer stated that he had no power in the sunroom located in his master bedroom. We recommend a troubleshoot in order to proceed with options for repair. Our findings consisted of; GFCI outlet was in the tripped position which controlled the circuit that lost power. Multiple outlets had both sets of different gauge wire. However, the breaker for the circuit was on a 20A which the 14 gauge wire is not rated for. The Main floor bathroom had no power to the outlets due to the hot jumper being capped off in the master bathroom outlet. ** this issue is under warranty due to it being overlook during a redevice** In addition to our findings we also found that the breaker for a dedicated outlet was tripping. We performed a separate troubleshoot and came up with options for that as well. We informed the customer of our findings and the possible repairs. *** NOTE: Customer wanted no major repairs for today and wanted everything put back with the small repairs.***

Tech Justin Zburlea was professional, courteous, and explained everything he was doing in terms we understood. He advised us of his ETA and on time. Parked his truck on road instead of driveway and wore shoe covers upon entering home. He was so kind and thoughtful and an asset to your company. Please thank him for a job well done and a pleasure to meet. We have finally found our permanent plumber for any other jobs that might come up in the future. You won’t be disappointed hiring this company and requesting Justin.

Today we replaced the home’s 18-year-old 50-gallon gas water heater located in the basement with a new Rheem ProG50 50-gallon gas water heater. In addition, we installed a new pressure reducing valve (PRV) and a new whole-house main shutoff valve to improve the home’s water distribution and serviceability. We also completed a rebuild of the second-floor master bathroom toilet to restore proper operation. Upon completion of all work, the plumbing system was repressurized, all fixtures were tested, and every connection was thoroughly inspected for leaks. At this time, all connections are leak-free and the water heater, plumbing system, and rebuilt toilet are operating properly. The customer is satisfied with today’s service.

I am going to wire and install four new can lights in the kitchen and remove the old fluorescent light. I am also going to install a new recessed can light in the hallway. Last I will be replacing the current recessed lights with the retrofit LED lights in the kitchen, the downstairs hallway and the upstairs hallway as well as the two in the great room. The total number will be 11. Update July 15: all lights were installed, including the four new ones in the kitchen and the new one in the hallway as well as replacing all of the current recessed lights with new retrofit recessed lights. For the great room, the holes in the ceiling were quite large, so I left the baffle in those however, when you get the sheet rock repaired, please give me a call and I will fix those to be flush like the others under your warranty. Thank you for using TE certified electrical! Veaya

Troubleshoot leaking upstairs tub faucet. Will need to order 1J-H/C stems to repair. Checked ice maker line in kitchen for leaks. Line was leaking before homeowner went on vacation and a neighbor tightened it up. No longer is leaking, but line is run on 1/4” copper which may kink and leak if fridge is moved around too much. Left estimate for replacing line and putting in new stop. Left estimate for 10 year old water heater in basement. Installed leak alarm next to it for a bit of peace of mind and left estimate for replacement.

Austin was my main electrician and he spent 4 hours diagnosing my electrical problems, showing me and explaining the issues, and then giving me 4 options of service. I choose to have a complete new circuit panel installed to replace my over 30 year old one along with a total home surge protector, new interconnected smoke/carbon monoxide alarms as well as other items to allow me to feel that all the safety issues were taken care of.

Called TEc around 8:30 this morning and was told they would send a team out to fix our air conditioner from 2:00 to 5:00. The same day!! Marvin Arrived around 3:30 (very professional) and left around 5:30. The air conditioner is blowing cold air. We’re happy campers!

A neighbor recently lost their house from overheated lithium batteries charging overnight in the garage. We called TE to install a heat detector as one step toward mitigating this. To do this it has to be wired into the other smoke detectors. Mauricio and Edwin did a very nice job locating the unit and wiring it with minimal drywall invasion. We also had another outlet placed in the garage. Very pleased with their work, as well as their friendly and professional approach. We will call TE again when need arises.

Doug Vaquero did an outstanding job helping us with what I deemed to be complex electrical work in our very old and antiquated house. He was knowledgeable, patient, methodical, and clearly knew exactly what he was doing, even when dealing with decades-old wiring challenges and unexpected issues. What really stood out was his professionalism and the way he took the time to explain everything clearly, ensure the work was done safely and correctly, and treat our home with care and respect throughout the entire process. It’s hard to find someone you can truly trust with complicated electrical work, especially in an older home, but Doug absolutely exceeded expectations. What’s more, it’s electricians like Doug (and Mauricio) who provide the exemplary service that keeps me coming back to TE Certified and why they’ve become my preferred trade vendor. I’ve been consistently impressed with TE, and it’s because of folks like Doug.
