"Dean and his team did in excellent job in installing my NEW HVAC system. I had been nursing my old system for the last couple of years. I finally went to the most trusted HVAC company that have worked with for years. The new system chills my first floor down in minutes. I should have done this sooner. Thanks for the all the folks that did the work and the professional staff in the front office and Sales."

"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."

"We moved from NY to GA to be near family?my wife is a disabled veteran battling cancer. We bought a home near her mom, hoping for stability. The upstairs AC wasn?t working, and Hammock?s stickers were all over the HVAC, so I assumed they?d serviced it. On 9/9, a tech diagnosed a bad transformer ($300) and added 3 lbs of refrigerant ($580). The invoice only listed 1 lb. The AC stopped working 45 minutes later. On 9/11, another tech said the transformer blew again and the first tech shouldn?t have serviced it. Fred came to quote a new system for $8,000 and said we?d lose the $880 if we didn?t replace it in 7 days. He was dismissive when I explained our situation. I followed up?calls, emails, voicemails?but got no response. Later, I found they left furnace covers off and exposed live wires. I sent photos. Their reply: ?We can send someone to put the covers back on but won?t refund you.? We paid $880 for 45 minutes of AC and were left with a dangerous setup."
