Great Experience
Meloney - Duluth, GA
Scott and Kyle were very polite and professional. It was a full day for several jobs.




Excellent service
Janet - Duluth, GA




Very pleased
Kenny - Duluth, GA
Fair pricing; didn't feel like I was being nickel and dimed. Omar patiently answered my multitude of questions. I thought he was very thorough with his work, double-checking everything he had touched. But there was one thing that really stuck out to me. Over the years, I've had a few water softeners/heaters installed by other plumbers, but Omar's work with the copper pipes over the water heater was by FAR, the most elegant I have seen.




Great service

Jonathan was terrific. He was very patient. He allowed us to explain what we wanted to be done, and he made recommendations from a SME point of view. After the work was completed, I had a last minute addition. He was very understanding and took his time and completed the work. Outstand service technician...

Superior installation and customer service
Kate - Duluth, GA
TE has done a lot of work for me in my new home. I specifically requested Jeffrey to return after his first service call because of his friendly and helpful demeanor and because of his superior technical skills with all my electrical needs. He worked through every problem providing me with options on how to proceed which instills confidence that TE is not trying upsell on all issues. Top notch company and technician!




Great install by the TEC team lead by Nick!
