" 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.

"⭐️⭐️⭐️⭐️⭐️ I want to start by highlighting the *above and beyond* service I received from Keep Smiling Heating & Air. In the midst of a brutal Atlanta heatwave, I called in a panic because my newer AC unit had suddenly stopped blowing cold air. From the first point of contact, the experience was incredibly professional and reassuring. I received a confirmation text, a follow-up call when the technician was in route, and even a text introduction with a picture and background info on the technician. Who does that? **Keep Smiling does.** Technician **Byron Solares** was exceptional—knowledgeable, professional, and genuinely empathetic. I explained that I have my elderly father with a breathing condition living with me, and Byron not only resolved the issue efficiently, but took the time to explain everything clearly. Thanks to his quick work, we’re resting comfortably tonight."

"Replaced some bad boards and loose railings. Did a great job."

"Carl is an expert craftsman. He replaced siding, rebuilt our deck and brought it up to code. He has hung TV’s and built an additional closet for a bedroom space. You will never regret hiring Carl for the task. He is fair, knowledgeable and always exceeds our expectations."

"Best, most reasonable HVAC company in the area! Very professional and personable. No surprises and quick response. "

"Removed Pedestal Lavatory, installed new Vanity Cabinet and faucet with new supply line risers, replaced two lavatory faucets with new supply line risers, checked shutoff valves. Vanity cabinet and faucets were provided by the customer. The Pedestal Lavatory had originally been installed without backing and it was not possible to fix/reinstall it the same way. Gabriel provided two options: 1. Attach it to the wall with special glue. 2. Install new vanity cabinet. Customer selected the second option. The old faucets were more than 20 years old, so it took some time for Gabriel to remove them, but he always maintained a positive attitude, installed everything as requested, checked everything after that, cleaned up and answered some additional customer questions. Overall assessment: Highly recommended."

"I’ve been using Dilfer Electric for years - they are my go to resource for any electrical needs. Diego and his wife are absolutely amazing - they’ve installed several light fixtures for us, diagnosed and fixed electrical problems, and are the nicest people you could work with. Would highly recommend them for any of your electrical or lighting needs in the Atlanta area."

"everything went smooth, they picked up within the 3 day window and actually delivered 3 days earlier then expected...and no scratches or any type of damage at all very happy thanks guys...great job"

"If Daniel is a representation of ALLGOOD PLUMBING as a company, I cannot recommend them enough. Fantastic! Daniel arrived at the expected time to give an estimate on the installation of a water heater. I did not have to wait around all day waiting for the technician to arrive. He was personable, professional and friendly. He was able to answer all of my questions and make recommendations. Upon my approval to purchase and have the water heater installed, it was not an all-day process. Daniel had to leave to go and retrieve the agreed upon water heater and when he returned with the water heater and other parts needed for the installation, Daniel was able to install the water heater in a very short time. Price was a bit on the high side for the industry, but compared to the other estimates or recommendations received, I feel the decision to use ALLGOOD PLUMBING was the best decision. So far, I am very satisfied with the water heater and installation. I would highly recommend ALLGOOD PLUMBING for installation of water heater needs."

"Service was great!  A 21 year old ceiling fan quit working in the upstairs Master Bedroom, an area of the house that heats up quickly during summer months.  I was hoping to be able to find someone available within a week to install the new fan.  Mark was accommodating and prompt to fit me in to his schedule within TWO DAYS!  What a pleasant suprise to finally find someone dependable, knowledgeable and concerned about doing the job right.  I will definitely contact Samson Handyman for future projects! <br /> Thanks for the great service! <br />"
