"Absolutely awful people - The "tech" (glorified salesman) came into my house trying to upsell me on a bunch of ineffectual products - when I declined - politely at that - he got hostile and started insulting me - when I reacted to his disrespectful attitude and told him to leave my property immediately - he then threatened me physically - he is very fortunate that I have a de-escalation attitude towards these matters - when the owner called me to ask about this - he promised he would make this right - he never did and the dangerous tech still works for him to this day. There's many other choices in this market - save yourself the headache and safety."

TE Certified Electrical, Plumbing, Heating & Cooling is a customer-focused residential service company. We fix & replace electrical, plumbing, and HVAC systems for Greater Atlanta homeowners. Please call our office to schedule your appointment today. 770-667-6937

"I recently had an electrical inspection done by TE Certified Electrical, Plumbing, Heating & Cooling, and I couldn’t be more impressed. From the moment the technician arrived, the experience was professional, thorough, and reassuring. They took the time to explain everything they found in a way that was easy to understand, and I felt confident I was in good hands. What stood out most was their attention to detail—they didn’t just check the basics, they inspected the entire system to ensure my home was safe and up to code. No high-pressure sales, just honest advice and helpful recommendations. I’ll absolutely be using TE Certified again and would highly recommend them to anyone looking for top-tier electrical service."
