"Our existing generator died. James diagnosed the problem and gave us a few options to repair or replace it. We chose to replace it. James handled everything, from getting and installing the new generator to electrical and fuel (propane) connections. We have asked him to schedule us for the annual maintenance on the machine. We are pleased, though we haven't lost power since it was installed, LOL."

"Unfortunately I hired NASR Electric for the purpose of repairing my Hot tub exterior circuit breaker panel, but his inspection revealed the problem was my hot tub, not the circuit breaker panel. Yet, he helped me get to the root of the problem, so now its off to a hot tub repair person..."

"Mr. Hyman and I talked on the phone and he was willing to work around what was a fairly fluid schedule. He texted to see if his staff could come by and we were able to quickly come by. Jeremy and his assistant arrived, put on booties and checked out the situation and explained the problem. They did the repairs quickly and neatly and were out in a bit more than an hour. They were friendly and efficient and when I expressed concern about not understanding the electrical language they were using Jeremy was super kind and let me ask questions until I understood what was going on. Having a patient, smart person who is wiling to help someone understand the repairs is wonderful. I would certainly contact them again for any electrical repairs."

"The installation men came at 8AM as promised since we were the first call of the day.  The two men inside starting to disassemble the unit inside while the other man removed the condenser outside and the platform and replaced it with a new platform and condenser.  They were able to do the entire job in under 4 hours including testing the cooling and heating units.  The sheet metal work was very professionally done with very little seams and looked more cohesive than what we had before.  They wrapped the pipes with installation like we had before and there was a new shut off box outside.  We are delighted with their workmanship.  It has been a little too cool to turn on the A/C but we know that it works since they have turned it on to test both the A/C and the furnace before they left.  It is suppose to be warmer this weekend so maybe we will have a chance to try it out.  We are very happy with GAC, Christine, the service person (Jermaine), the estimator, QA and the installers.  We are looking for a good relationship with GAC now that they are our A/C company."

"Ludwing did an amazing job! He installed a new light fixture in my home and what I appreciated the most was that he explained the connection to the wiring and how things work. This was very helpful because he corrected a job from a handyman who installed a light fixture that could have destroyed my home. He is a master of his craft. Not only will I use him for future projects but have also shared his contact with friends needing electronic assistance."

"I hired David for an inspection and repair of a circuit faulted after a lightning strike nearby. He accommodated my request very promptly (same day after 6pm, so I did not have to take a day off for this!). He replaced a damaged GFCI outlet and tested the rest of the circuit, inspected the main electrical panel as requested. It was a very friendly experience, and a very reasonable cost (he seems quite flexible about cost too!). Would definitely hire again for any future electrical problems."

"This company resolved my electrical issue quickly and professionally. The technician was knowledgeable and clearly explained what was wrong and how they fixed it. I was expecting a longer wait, so I was grateful they could get to me so soon. Pricing was fair and the whole experience was excellent. I def highly recommend this company to anyone needing electrical work done. Thank you!!!"

FAQs for generator repair projects in Rockville, MD

Always start by confirming the pro’s license number, insurance coverage, and experience level. Visit the electrician’s website, scan recent customer reviews, and verify credentials with your local labor department. Request proof of liability insurance and at least two references that you can contact. These quick checks take only a few minutes but go a long way toward ensuring safe, code-compliant work and protecting your home in the event of an issue.

Grouping several electrical jobs into one appointment means you pay a single service-call fee and one set of travel expenses. Instead of asking a pro to return three separate times for outlets, switches, and fixtures, have everything tackled in one visit. The electrician stays productive, and you avoid extra trip charges, often shaving a sizable chunk off the final bill without compromising quality.

DIY electrical work can be dangerous and, in many areas, illegal without a license. One miswired connection risks shocks, fires, or expensive damage. Licensed electricians carry the right tools, follow local code, and know how to shut down power safely before they start. Hiring a pro may cost more upfront, but it protects your home, family, and insurance coverage in the long run.
