"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."
"I had an excellent experience with Kevin. He installed a very large and complex crystal chandelier in our foyer, and the entire process was handled with exceptional professionalism and precision. This was not a simple installation,the chandelier is heavy, intricate, and required careful assembly and mounting at a significant height,but he approached the job with patience, attention to detail, and clear expertise.
He took the time to ensure every component was perfectly aligned and secure, and the final result looks absolutely stunning. The installation was done safely, efficiently, and with great care for our home.
I would highly recommend him to anyone needing electrical work, especially for challenging or high-end lighting installations. Truly outstanding workmanship."
"Outstanding! Super professional. Offered advice on my electrical installation and did the work quickly. I was very pleased with the end installation."
"Your technician that came out to do a yearly maintenance inspection on my generator was very nice and knowledgeable. He arrived actually earlier than expected and went right to work. I would recommend your company to anyone and it was so nice to deal with someone who acted like they enjoyed their work and wanted to please. Thank you!"
"Outstanding service. I originally needed an electrician to determine why I lost power to ½ my house. What Jody uncovered was a defective circuit breaker and my main switches overheating and in the process of melting down. He was able to change out the panel and install new breakers immediately. I’m grateful for the prompt response by Gene and the professionalism of Jody and Brian."

"Ron Ethridge (owner) did the work. He was friendly, helpful, knowledgeable, and experienced. He was available on the phone during the project - after hours and weekends. He is very familiar with permitting and licensing and working with Pepco and the inspectors."
"Patrick, who supervised the installation of a generator which I had, also worked up the initial recommendations and estimate. This generator was used, but that did not deter Patrick from coming up with a plan. Other contractors sent estimators who were more sales people than experienced generator contractors. Only Ritzau made the recommendation to replace the old fashioned transfer switch which came with the unit with an up to date digital transfer switch. This "
"I originally called Anthony because I really needed help, I had just let another Electrican go and needed someone to step in to fix an electrical problem. He responded within minutes to my request, the Team did a fantastic job installing my Clients light fixtures and new electrical outlets. They were extremely professional, walked us through each step explaining what would need to happen. Their pricing was reasonable and fair. If I had a question or a concern, Anthony responded quickly to my questions. I would strongly recommend them to anyone. They are now my Electrical resource, which is a resource my Clients expect as we are a full-Interior Design Consulting Company. Thanks Mimi"
In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.
If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.
