"This is an American US Citizen company with working American employees. Cole arrived with 18 yrs of electrical experience. WOW he knows his stuff. I had a ancient electrical box with federal breakers which are known to cause fires. Cole said my old box was in bad shape. It was a no brainer to spend the money and upgrade to general electric breakers. I also hired him to hard wire my carbon and smoke detectors. Job #1 took 2 days. The other work will be done in August 2021. For an experience electrician this is your company."

"TE Certified is my go to company for any services they provide. I had 4 heat pumps replaced with them, various plumbing/electrical, and most recently a whole house generator. Billy did a great job showing the generator options and managing the sales/install cycle. Matt and team did a fantastic job installing the system and showing me how it all worked. TE Certified always uses high quality materials and workmanship for long term error free operations. The county inspector even commented on how good it all looked. I highly recommend them for any of the services they provide."

FAQs for generator repair projects in Marietta, GA

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.
