Rated 5 out of 5 by from FINALLY!!!! First and foremost thank you to Metro Electric for the exceptional customer service and installation. The team is spot on from the time they arrived until the job was finished and they left everything as neat and tidy as if they were not even here working. This was a tremendous purchase for our household and I can't wait until the power goes out. Anyone living with a well and septic knows how difficult life becomes when the lights go out! It has been four weeks and still waiting to solidify why this was the best decision ever. I'm sure it will be worth it! Thank you Generac for the extended warranty and I am certain what will be a quality product.

Rated 4 out of 5 by from Whole House Generator I replaced a small generator with a new 24kW Generac. The WiFi connection took an old person a little time and effort. But it is connected and ready to run. I no longer will have to worry about being without power. The auto start and transfer switch will be great. Not that I want to have a power outage. But we are ready for it when it happens, and it will.

Rated 5 out of 5 by from Polite, quality, done in a day Team arrived on site at the set date and time. They explained the entire process including the placement and power outage time. After the work was completeted, they explained his everything worked and went through a simulated power outage. Everything worked like a charm. The operation if the unit is virtually automatic. Everything in the house can operate with the generator running. Job well done, happy with my results!

Rated 5 out of 5 by from Piece of mind - finally The entire process, from quotation to installation, took a bit of time due to a significant order backlog, but overall I'm happy with the process through SPS. They responded to queries and kept me informed as to status. The installers were very professional. The Generac appears to be made of high quality materials and offers several key features.

Rated 5 out of 5 by from First Official Call Up It has been just over 12 months since our unit was installed. I have held out this long with writing a review until such time so I could witness a real loss of main power and the automatic switch and start/load sequence work. About an hour ago we had a lightning strike which knocked out power. I jumped out my chair excited (weird I know) but finally a real event. It started and loaded in between 15 to 20 seconds which was the way I wanted it and it is doing great. When the A/C kicked on, that initial surge caused a split second RPM drop, but that is to be expected. A year ago I was hesitant with such a large dollar purchase for "maybe" and today I have no regrets. Great product. Our dealer was Optimize EGS out of Scott Louisiana. Peace be with you
