"Jeremy Reel completed the install to perfection. He installed a 50A breaker and the Level 2 Charger. When the car was only charging to 32A he stayed and trouble shot the issue for an extra hour. As it turns out, 32A was the max the car would charge at. I was very satisfied with TE Certified and would recommend them to anyone."

"Last year (2021), I hired Casteel to upgrade my HVAC system, tankless water heater, update the pipes in my basement, install a pump for washing machine and bring my electricity. I have a brink home the was built in 1955 and had not had any major repairs since 1985. Everyone I spoke to during the process of consulting and repair was professional, kind and courteous. They always kept an open line of communication and were willing to adjust their schedule according to emergency circumstances that happened in my family. From the products they used to the quality of the workmanship, I am still very pleased with outcome. They respected not only my time but my property too. I will definitely hire them again. I highly recommend them to anyone in the Atlanta, GA area."
