"When my water heater failed, I decided to replace the unit. I received quotes from severaI plumbing contractors and selected Atlanta Tankless and Water Heater. The owner, Donald Rogerson, assessed the situation and, unlike the other contractors, provided me with options for replacement of the water heater. He was intelligent, knowledgeable and courteous. On the day of installation, he completed the work in an efficient and professional manner. Donald is the ultimate professional!"

"I used Greenlee to replace my water heater. They replied to my inquiry for service very quickly, even though it was after normal business hours. They were responsive and professional assisting me in determining the best solution for me. They arrived quickly and on time. Their work was fast and they did a great job of removing my old water heater and installing the new one. Everyone with whom I had contact was friendly and professional. They will be handling any future plumbing work that I have."

"John was very professional and knowledgeable with the tankless water heater. He addressed my issue and resolved it in a timely fashion"

"Excellent service with water heater and electrical. Technicians were prompt and very knowledgeable."

"My water heater got flooded due to the recent hurricane rains. Chen Plumbing came out same day and was able to get a new water heater installed in less than an hour. I appreciate their technician's professionalism and attention to detail as well. Thank you!"

"Navien Tankless Hot water heater was not putting out adequate hot water. Matthew Jones was able to troubleshoot the system, finding a valve with a bad o-ring. The valve was replaced and we have plenty of hot water now. Matt was very courteous, friendly and most of all a confident worker."

"I cannot say enough good things about Mitchell and Demarcus. They called when they were on the way, arrived on time, and completed the installation in just a few hours. It was a tough job. The water heater was partially blocked by the furnace but Mitchell figured out how to remove the old heater without having to remove part of a wall, which is what I expected would have to happen. He re-piped the connections (the old piping was a mess!) ran the gas line extension to my stove area and placed the new heater. I had hot water within a few hours of job completion. I now look forward to hiring Mitchell again to install my new gas stove (once I buy it). I highly recommend Cool Air. I will receive a 10% discount on the water heater in the form of a gift card because I'm a Costco member."

"It went well! Matt and TC at Plumb Life ATL are very professional and communicative. Matt called the day before to let us know when the plumber, TC would be arriving. On the day we were scheduled, TC called an hour before he was scheduled to let us know when he'd be arriving. TC was very punctual and determined to find the source of our water leak. He removed the water heater in less than no time. Then he explained to my wife and I that he needed to cut into the wall to find the leak. He then neatly cut into the wall and found rusty nails all throughout our piping. He removed the damaged pipe and neatly installed new piping in that area. We no longer have a water leak issue thanks to TC and Matt. Matt was also very communicative from the onset to the conclusion of the work. We highly recommend their services. ⭐⭐⭐⭐⭐"

"It was a Sunday and we had a water leak."

" Update from 20 Jan 2026: I`ve been a repeat customer of Keep Smiling Plumber, Electrical, Heating and Cooling in the past for several home-related repairs. After having an unfortunate experience with Keep Smiling PEHC during my most recent service, I had some misgivings about the company and whether I would return as a customer. In regards to their customer service, everyone that I`ve engaged with (technicians, onsite supervisor, receptionist) has always been professional and courteous which goes a long way with me. The issue that I had was technical in nature and left me with some dissatisfaction regarding the quality of work. After speaking with leadership of this organization Mr. Powell and Ms. Amy ,I believe that they hold the highest standards and expectations for their employees and ensure that any work-related issues are duly addressed/resolved. I can sincerely say that they have regained my confidence and trust in contacting them in the future for my future HVAC, Electrical and Plumbing home needs. The manager I spoke with told me that there wasn`t any way the damage of the pump could come from the technician doing a drain and flush of the water heater. He told me that it would cost $1200 to replace the pump on the water heater. After speaking with the manager at Keep Smiling, I called another company which I`ve seen before in the community and spoke with a plumber and explained to him what happened. The technician at the other company told me that the pump could definitely be damaged if the pump was still plugged up and not turned off while the water heater was being drained and flush. I called the manager at Keep Smiling and shared those details with him and he replied that he understands what I`m saying but there was nothing he could do about it. I told him that I don`t have any reason to lie about any of this and felt very frustrated and cheated by the fact that I went in expecting for them to do a maintenance check for $59 for plumbing but ended up spending a $1000 for new.
