Just prior to a horrific snow and ice storm, our generator failed. Our existing company told us we needed a whole new generator costing up to $10,000. Thankfully, we contacted Generator Superstore of Annapolis for another opinion. They understood the urgency and sent a technician out within days. After 20 minutes, he discovered the issue was simply a loose wire. He tightened it and we were fully operational before the storm. Professional, honest, and responsive.
I would highly recommend GSC… from the time Sarah came out to give us a quote right up to the installation was like clockwork. A one-day installation for all that was needed to coordinate was impressive. I would like to commend the office team, Kara & Veronica, and the install team with master electrician James. Enough can’t be said about Mike Scott the electrician; he has a great personality and is super skilled.
We had debated on getting a generator for years and boy are we glad we did it! Installation was completed on Thursday and we had an extended power outage just two days later. It was so incredibly nice to be able to take a hot shower and go about life without any interruptions. Generator Supercenter of Annapolis was great! Would highly recommend!
