Get matched with top heat pump installers and replacers in Lawrenceville, GA

"Jonus (Tech) was very thorough in making sure that my condensation line was not clogged and that the pump and switch were not working properly before replacing. He took the time to answer all my questions and even crawled through my cramped attic in blazing heat to make sure my condensation line was not clogged. I was very impressed with his great attitude and work ethic."

"Reliable, honest service, and fair prices. They just did a two-system replacement for us and it went extremely well. I've been working with Robby and his team for over 10 years on behalf of third-party clients and he is one of the most trustworthy contractors I've known. When I moved to the Atlanta area two years ago it was a no-brainer to hire R Wiley for my home's yearly HVAC maintenance package and I'm glad I did. We've had Miguel, one of R Wiley's outstanding technicians out for service and maintenance and I've been happy with his work and helping to diagnose issues. When it came time to replace our very old AC & Furnace units, there was no sales pressure - just consultative solutions. R Wiley's pricing was in line with some of the more affordable bids and they don't try to push you into super high-priced marked-up units or things that should be included with installation, or all those "financing" programs where you end up paying way more for your project. Installation with Marvin was awesome - they were done with two units in one day and what a difference it's made. Overall an awesome experience from day one, with a successful multiple unit replacement. I'm glad I have them to continue to keep the units serviced on an annual basis as well. Highly recommend!"

"My heat pump had a Freon leak. The technician discussed the options. I later decided to replace the unit. Estes did the work. I have used them for many years. I have been very happy with their service."

"Top notch company - installed our new AC/Heating units two years ago. I was a bit pricey, but has performed flawlessly. Subsequent service calls have been reasonable and professional. Highly recommend."

"Craig, the technician was courteous and professional. He even reinforced an outlet box that had not been appropriately installed/secured (by the original builder or previous installer). I'm not familiar with the cost of electrical work, so my initial thought was that they were a little bit pricey. However, after seeing the quality and diligence of their work, it was definitely worth the cost."

"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.

"Outstanding company of real professionals. Work performed: 1. All power receptacles and switches were upgraded (new parts replaced old, wornout parts). 2. Assembled and install two (2) new customer supplied ceiling fans . 3. Provided and installed new 15A convenience 0utlet. 4. Provided and installed single pole 15A/20A arc fault breaker I have an eye for detail. Minor discrepancies leap out to me as well as minor work done well. Perhaps, twenty-two years in the military created this effect upon me. Sometimes it's a blessing and sometimes a curse as I find myself unable to accept minor, shoddy work. Example: All of the screws to the new face plates for receptacles and switches were oriented with the screwdriver slots in the vertical position. This was not done by chance by the team's three electricians but by their attention to detail and uniformity. If the small things are done perfectly, I feel it is safe to assume that all of the larger work is too. I have four more electrical projects to be accomplished and TE Certified Electricians will be my "go-to" company for these activities. I highly recommend TE Certified Electricians for your electrical projects."

"Expertly. The latest ATL cold snap killed my decades old hot water pump when I merely switched my thermostat from Cool to Heat. Common sense drew me to search the internet's reviews for Plumbers near me with the highest rated reviews. Weather Masters was an obvious choice and I have been very impressed with how quickly I was made to feel that I was now their #1 priority. Recognizing my dilema, they worked fast, as we were mere hours before a busy holiday week. I then asked if they might also examine my old rusting A/C unit. At the time of this review, everything has been completed. I am so happy I called Weather Masters. Their work was expertly done, all was performed on my schedule, and most important, was reasonably priced. When working with Weather Masters it was quickly apparent that Jason and Robert's years of experience and practical know how unquestionably contributes daily to Weather Masters operation and outstanding professional results. Thank you so much Kristen*, James, Jason, Robert, Tony, Brian, Jose and Traci, to name a few. You are truly The Best!! *Special Thank You for your extra effort when you made certain my call made to Weather Masters late that Friday afternoon was met with "Yes we can help you.""
