Returning Customer of TE Certified

I previously worked with TE Certified for an electrical repair and was pleased with their service. This was my first time contacting them for HVAC work and I worked with Albert Nah. I was impressed by the level of professionalism and expertise Albert brought to the visit. He completed a detailed diagnostic of my system, explained his findings clearly, and laid out all of my options in a way that made sense—no pressure, just honest guidance based on what the equipment actually needed and what my choices were. He identified issues that were overlooked by others, clarified what was necessary versus optional, and helped me understand both the immediate repairs and longer-term preventative steps. He was organized and transparent throughout. Additionally, to support his assessment and recommendations, he shared photographs of my equipment and gauge readings. His explanations were thorough and demonstrated a real depth of knowledge. It’s rare to meet a technician who delivers this level of clarity and integrity. TE Certified will continue to be who I call for major home system repairs.

Customer called us out for a clogged master bathroom shower. I inspected the drain and saw lots of lime scale build up. I recommended scraping the sides and running a tub gun down the drain to clear anything further down the line. Customer agreed. The lime scale was very hard to remove, I got most of it off but was unable to remove it all. Shower was draining very well after testing with no signs of backing up.

We replaced the angle stop valves beneath the left sink in the master bathroom to ensure the water supply to the faucet can be properly shut off until a new faucet is installed. This work allows the fixture to be isolated safely and prevents unwanted water flow while awaiting the replacement faucet. While on site, we identified an active leak on the main water service line at the shutoff valve located before the water meter on the city side of the service line. This section of the line is the responsibility of the City of Atlanta. The homeowner was informed of the condition and advised to contact the City of Atlanta Department of Watershed Management to have the leak addressed to prevent continued water loss.

Customer was experiencing issues where there was very very low water pressure. Check the aerators and they were full of debris. My client had mentioned that the workers who were pouring the new driveway had hit an irrigation line, my initial step in the diagnostic phase was to replace the PRV, which had been limiting flow due to a strainer full of debris. The PRV was old enough to warrant replacement. After replacing the PRV and installing a shut off valve as a courtesy. I noticed that the water pressure was marginally better but still a problem. After some troubleshooting, I’ve come to the conclusion that there is a break in the water service line, but could not find any leaks. I can hear the water meter running but cannot get the display to show any numbers. My client opted for leak detection search to verify that the leak we are experiencing is on the water service and is not an additional irrigation issue. From there, we will opt for a water service replacement. Current water serv
