For this show, I rendered leak detection service for Mr. and Mrs. Westbrook, as a TGL for original technician Leo from the west side office. This property is located right on a busy main road just off of Chamblee Dunwoody, which made it difficult to delineate between ground frequency, and the frequency of water escaping the main service however, upon further investigation, I noticed water saturating the ground in front of the meter between the existing water meter box and the irrigation shut off box just in front of it when I listened here is where I had the most delineation and frequency I marked the area with a blue flag, and also observe water coming back into the water main box indicating the leak to either be just in front of the box or possibly just after the dual check valve before terminating the water main service meter box.

For this job, the customer had us complete a car charger outlet eight years ago and has recently been getting heat error codes on her Tesla car. I inspected the work we completed and everything looked in order. The voltage is correct and the connections are tight. I gave the customer options to replace the outlet and breaker or to install a hard wired wall connector.

TE certified will cut out and replace approximately 20 feet of drain line located in the basement ceiling from the bedroom up to the bathroom. In the process of gaining access to the piping ceiling tiles and light fixtures and sheet rock may need to be removed and will probably be damaged in the process. TE certified will not be responsible for any repairs. The drain piping replaced will come with a lifetime workmanship warranty.

Today I performed a troubleshoot on an issue with outlets in the pantry. My findings are detailed in the invoice. I also noticed multiple unlisted breakers present in the panel, all of which I replaced. I also had to splice together multiple circuits as the panel has no remaining spaces. I also noticed the neutral bonding screw present in the main panel, which is not the first point of disconnect, so I removed it. I installed a new 15 amp dual function breaker for the pantry outlets, and I replaced 4 outlets in the pantry. I also installed a whole home surge protector in the main disconnect outside.

Came in today because system was not working properly. Customer mention that we were here, not too long ago and replace all the main components in the system. System is only one year old. Customer also mention that there was a power outage a couple days ago. When testing system there was power but it was showing am error, when resetting the system furnace came back to normal and heat started working properly. This prior error was caused by a power outage. Costumer also signed for home care maintenance to make sure everything is working as it should. Proceed Change filter, tested all electrical components, flushed drain line, tested thermostat. System is working properly at this time. Thank you for choosing TE Certified!

Jonah did not seem confident in any communication. Was on the phone and checking the how-to manual. Other guy with him looked at the giant furnace and asked if it was a heat pump. They were pleasant and professional, but didn’t give “we’ve got this under control” vibes. Price for diagnostic was fine. Repair quote seems high.

Out of nowhere, a bathroom outlet started hissing and grinding. We got scared. I Googled “electrician Dunwoody” and started calling places. The first outfit I called said they could send someone- in three days! Next I called TE Certified. The answering agent said our outlet issue was urgent and she put us on the top of the list for same-day service. Within three hours, Jesus arrived. He called first, when he was a half-hour away. He arrived when he said he would and couldn’t have been nicer. He tested things and explained everything. He gave us options for fixes, and then he fixed us up. Very grateful to TE and Jesus, and the woman who answered my call!
