"Every section of the generator was checked. Things that were worn or in need of updating were pointed out and were replaced or repaired whatever was needed. Everything was explained very well which makes coming to a decision about whether to fix or let it go for a while was easy. Fix it now! My generator got a trial update and no I have nothing to be concerned about!"

"Hank is very affable and we hit it off right away...I could tell from the get-go that he was very honest and reasonable.  He came when he said he would come and scheduled a service disconnect with the power company without issues.  He was here for at least 3 full days doing the work and he was willing to work with the panel I bought off of Amazon.com, saving some money.  His wiring prowess is quite good and he knows his stuff.  Best of all, he's willing to work with you to do stuff, even if your plans change and the work needs to be adjusted for certain constraints.  He gave me a quote for $2,000 dollars and that was the total price at the end.  He even allowed my (very mechanically proficient) 10yr old son tag along and educate him along the way!  He worked by himself.  
I wouldn't hesitate to call Hank again, and I will definitely have him back to finish up the compressor wiring and the generator I will purchase.  He's a great guy, honest, and a hard worker all rolled up into one!

"Generators of Maine just completed the installation of a 14kw generator with parallel transfer switches, to protect 2 separate metered panels at a rental property that I own. I didn't even know that this was possible, until Doug Sawyer suggested it. The incremental cost of protecting the additional panel with the parallel transfer switch arrangement was a fraction the cost of an additional generator and transfer switch. Throughout the job, Doug and his crew were awesome. I am a terrible snoop who enjoys technology, so I hung around just watching and learning. They didn't seem to mind my presence and were friendly and informative through out the install. Every aspect of the job was 100% top-notch. Doug also managed to under bid his nearest competitor on every component and aspect of the job, including the annual maintenance contract, which I deemed to be worth the $$$. I highly recommend Generators of Maine."

FAQs for generator repair projects in Cumberland-center, ME

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.
