Power outages in Atlanta can strike without warning, taking out lights, HVAC systems, refrigerators, and critical devices in seconds. At R.S. Andrews, we provide storm-ready generator solutions that help you stay protected, comfortable, and in control—even during the most unpredictable weather. Our licensed electricians install and service reliable backup generators that keep your home or business running without interruption. We help you prepare ahead of time, so you’re never left in the dark when the grid goes down. With over 50 years serving the Atlanta Metro Area, we know what it takes to power through a storm.

Who Should Have a Generator?

Backup power isn’t just a luxury—it’s a practical investment for anyone who wants to maintain comfort, safety, and functionality during outages. In the Greater Atlanta Area, where storms and grid instability are a growing concern, a generator can make all the difference. If any of the situations below apply to your home or lifestyle, it’s time to consider installing one:

  • You experience frequent power outages: If your neighborhood loses power often, a generator keeps your home running without interruption.

  • You rely on medical equipment at home: Devices like oxygen machines or powered mobility equipment need consistent electricity.

  • You work remotely or operate a home business: A sudden outage can disrupt work, communication, and online security systems.

  • You have perishable goods or sensitive electronics: Avoid losing hundreds of dollars in spoiled food or damaged equipment.

  • You want to stay secure during storms: Keep your lights, security systems, and climate control operational during bad weather.

  • You live in an area with storm-prone seasons: Heavy rain, wind, and lightning are common in Atlanta and can knock out the grid quickly.

Schedule today! We’re ready to deliver expert service and a smile to your door.

Our Protective Generator Services

Whole-Home Generator Installation

We install high-performance whole-home generators that automatically restore power within seconds of an outage. These systems are permanently connected to your home’s electrical panel and fueled by natural gas or propane. Our team designs each installation to match your property’s size, energy demands, and long-term needs.

Generator Repair & Troubleshooting

If your existing generator fails to start, makes odd noises, or isn’t powering key circuits, we can help. Our electricians diagnose issues quickly and perform the necessary repairs using trusted parts and proven methods. We restore full functionality and ensure you’re ready for the next outage.

Generator Maintenance Services

Like any mechanical system, generators need routine care to stay reliable. We offer scheduled maintenance that includes fluid checks, filter replacements, battery testing, and load simulations. This preventative approach keeps your unit ready for year-round performance in the Atlanta Metro Area.

Load Assessment & Sizing Consultations

Choosing the wrong generator size can result in overloads or wasted fuel. Our team performs in-depth load calculations to determine the ideal capacity for your home and lifestyle. We walk you through your options to ensure the system fits both your budget and backup goals.

Transfer Switch Installation

A properly installed transfer switch ensures safe, automatic transition between utility power and generator power. We install both manual and automatic transfer switches depending on your system and preference. This upgrade protects your appliances and keeps your home fully powered without hassle.

A backup generator is one of the smartest ways to protect your home—but only if it’s installed and maintained by experts who understand what’s at stake. At R.S. Andrews, we take the time to assess your power needs, explain your options clearly, and deliver seamless service from start to finish. When the lights go out, our customers stay safe, comfortable, and connected.

My 87 year old mom’s 23 year old AC went out on a 95 degree day. I called RS Andrews at 7 AM. Repairman was onsite by lunchtime. The system was beyond repair. Sales rep was onsite before 5 PM. New Lenox system purchased by 6 PM. Installers and electrician onsite the next morning and project complete before 1 PM. Just WOW! Thanks RS Andrews.

First time using RS Andrews and Pau Sum was absolutely wonderful! He was extremely informative, sent pictures and videos of his work, and tested everything before leaving to make sure it was working properly with no leaks. I will be using them much more in the future!

David Stitt and his team did a great job today figuring out what was going on in our home with some complicated plumbing issues. Many other plumbers could not figure it out. Very knowledgeable and friendly. Thanks!

Upon coming home from a short trip on a Sunday we discovered that our AC was down. RS Andrews was able to send out a technician by mid-day Monday (during a heat wave). Anthony French was able to troubleshoot the problem and make the repair onsite. He was very pleasant, efficient & professional, and answered my many questions. He took the necessary time to help me understand the repair proposed and costs involved. Excellent job!

RS Andrews keeps my home systems working...waking up and finding a large pool of water on your kitchen floor can be frustrating! However, I called RS Andrews and they had an opening at that time...James Mays arrived 45 mins later replaced a faulty faucet and within the hour everything was back up and running smoothly! Thank you RSAndrews/Mr. Mays!

Excellent service from technician Waqas. Punctual, courteous, knowledgeable, patient and thorough. Everything you’d want! Completely satisfied! Plumber Zeke has been here twice. A third and possibly fourth visit are expected. First was an emergency response to a leak- he determined that the issue was HVAC rather than plumbing. For today’s visit he removed the water heater-necessary so that the HVAC installation team can put in a new system tomorrow. As before he was friendly, knowledgeable, efficient and effective. He made it look easy. Having assisted with this unit’s installation I’m fully aware that it’s far, far from easy. I expect that the subsequent new water heater installation will be of equally high caliber.

Great experience having the HVAC unit replaced in my condo. Max was very professional, from start to finish he kept me informed about each step, tested the unit thoroughly, and did a great job. Amber from sales was great as well, explaining the options and making the process super easy and efficient. Highly recommend.

I contacted RD Andrews to inquire about getting the attic above my garage insulated. Terry Taylor was assigned and he come to my place and gave me a very thorough opinion of the need and what I might consider. By the time he was ready to leave, I had decided that I would definitely move forward with the work as we discussed. I was pleasantly surprised to learn that the work could be done the following day and that Terry would be the installer. As promised, the next day Terry and his associate arrived when promised and within 2.5 hours, the work and all associated cleanup was complete. He provided me with photos of the "before and after". Terrific work! I am very happy with all that was done. You can bet that future need will be offered to RS Andrews. The photos are before and after.

I would highly recommend RS Andrews. I've used them in the past, but it had been a while. I needed a quote for something, and Loren Palmer came out and did a fantastic job. He was on time, early even, polite, professional, he came in and looked at what we needed done, and gave a quote on the spot, which was very competitive. They had great communication, highly recommend.

I had the pleasure of working with Jonathan Balom from RS Andrews when I encountered an issue with my air conditioner. From the moment he arrived, Jonathan demonstrated the utmost professionalism—he was punctual, polite, and incredibly efficient in diagnosing the problem. While the final recommendation was to replace my unit—an unexpected and potentially overwhelming outcome—Jonathan handled the situation with compassion and care. He gave me a moment to process the news and then took the time to thoroughly walk me through all of my options. What impressed me most was how clearly and simply he explained everything. He avoided technical jargon and made sure I understood why a replacement was the best course of action. Jonathan’s expertise, patience, and respectful demeanor made a difficult situation much easier to manage. I’m truly grateful for his help and highly recommend both him and RS Andrews to anyone in need of HVAC services.

Kwame Kilgore was a wonderful technician. He was pleasant, polite and kept us well informed about the work he was doing clearly and often. Earlier this year we had RS Andrews install a new water heater and after Kwame came to our home this time for the air conditioning repair we knew then using RS Andrews was the right choice for us. We will be your customer for as long as we own our home. 5 STARS!

Had a couple of small punch list items from a Home Inspection we needed to complete before Closing. Contacted R S Andrews on phone and their Call Center (Alison) was so helpful. Set an appointment for the next morning Received a super nice call (Ashley), first thing, to check all was still okay for the Electrician to come. Electrician arrived on time (Travon Jackson). He was extremely professional and friendly. Provided a quote for all work, and as it was acceptable, he did the work right away. In and out in 30 mins. A great experience and one I would recommend to people looking for fast, efficient, professional service for any electrical job. Travon had a ceiling fan replacement and a bathroom fan to fit later that day to give an idea of the breadth of jobs they are able to accommodate.
