"Joseph came to our home on 8 /28/21, to replace an outdoor GFI outlet. He was punctual, professional, and quite easy to work with. While he was there, I asked him to take a look at our very old electrical panel, and would he consider replacing it at a later date. He said, he needed to check his schedule and get back to me. He did. Joseph obtained the permit. We agreed on a date to install the new panel. I am very satisfied with the work performed by Joseph and his assistants. I'm sure it will pass inspection without issue. He's very good at what he does! Yes, I would hire again. Yes, I definitely would recommend."

"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."

"Jeremy and his apprentice Kevin did an outstanding job. They were thorough, professional, polite, and explained the work being done throughout the job. Our house's electrical system was over 60 years old and not up to code or safe. Our fuse box was replaced with a new panel and breakers. The Pepco inspector remarked that Hyman's installation was one of the best installations that he has ever inspected. All of our outlets and switches were updated to meet code. The team found and resolved several problems that were serious safety issues. Our kitchen was upgraded so we could operate appliances without overloading the system. A line was installed to operate our air conditioner condensate pump directly and not from an extension cord. This was an expensive project and I know that I received the best service possible. I am very grateful to William Hyman Electrical for making our home safe."

"Deybi was super professional and he took the time to explain the electrical system in my old house and recommended the best option. He and his partner also took the time after the work was done to clean up after the work was done and made sure that I was satisfied with the final work. Would definitely hire again!"

"Oupekkha showed up exactly on time, explained clearly what he was doing, what his annual service contract included and reassured me that our generator is good to go. He even topped off the oil for us. I signed up!"

Generator Install questions, answered by experts

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.
