"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."

"Long Electric goes above and beyond, here's how: 1. Generator maintenance: They have a thorough checklist, make a log of all repairs and replacements and then -- they clean the generator inside and out. We have had generators for 15 years and no other company took the time to clean the thing -- AND they're less expensive than most other electrical contractors. 2. Long Electric has always been at the house within 12 hours of a call for service. Example: We suffered a lightening strike to the house, which damaged anything in the house with a mother board, including the generator. Patrick, the master electrician who services our house, was here within 12 hours and installed surge protectors, repaired several GFI outlets that had been fried, got our electrical situation straightened out in one day. 3. A week after the lightening strike we lost power and found that the generator's mother board got fried due to the lightening strike and Patrick was able to diagnose it, repair and and get us back up in one day. Call Long Electric -- they'll install it or repair it in short order and have you back to normal. We would't go to another company."

"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..."

"I contacted Sci-Fi Homes in connection with installing a whole house generator last year while doing a major renovation on my home. My initial reason for contacting them was to "pick their brain" on the process as I didn't think I could afford their services. Marshall was quick to respond and was totally professional and courteous during our initial meeting. He provided an extremely detailed quote just a few days later. The price was very competitive and combined with their overall professional and friendly demeanor awarding them the job was a no-brainer.

Marshall took on the added responsibility of coordinating with the contractor, propane provider and the electric company as well. Everything came off without a hitch. Our fuse box situation was a particular mess so we decided to have Marshall and Tony do that job too, because of how well the generator installation went. Once again, a first class job! We had to fire our contractor 8 months in to a promised 4 month job and we found ourselves in a real bind. All facets of that project had been started but nothing had been completed.

The electric work was a real disaster. Once again, it was Marshall and Tony to the rescue! It took them a week to figure out what had and had not been done, what was not done correctly and get it all straightened out and working. They really went above and beyond. I will be using Sci-Fi Homes for all of my electrical needs from now on. They are simply the best!"

"Jared, the owner of JK Electric is hard working, polite and very knowledgeable. Jared changed all our ceiling fixtures and put in new outlets and switches. We had just moved in and were not knowledgeable about owning and 80 year old house and he taught us things to be aware of concerning electricity. He was professional and neat. We are new to Frederick and Jared will now be our go to electrician. I would highly recommend him to neighbors, friends, and family. Thank you Jared!"

FAQs for generator repair projects in Frederick, 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.
