What Customers Are Saying

Customers overwhelmingly praise the generator for reliable automatic operation, seamless power transfer within seconds, and handling high-demand appliances during outages. Many report life-changing experiences during actual power failures, describing it as a "Godsend" that keeps homes warm and routines uninterrupted. The app notifications and remote monitoring provide significant peace of mind. However, some experience WiFi connectivity issues with the mobile app, and several encountered installation delays or service inconsistencies. Despite these drawbacks, most customers consider it an essential safety investment they wish they'd purchased sooner.

Reliability

In all three homes I’ve owned. I’ve had a generic generator I can count on in case of emergencies.

Priceless

Would Recommend

I bought this about five weeks ago and have been so happy with it because we’ve talked about it for years. Within those five weeks I’ve lost power twice one was very short. The second time was a little over four hours and that was an important day for us to have power and my Generac worked perfectly.

Dead on arrival

1st unit would not work, and Generac would not stand behind the unit or repair it. The supplier had to replace at cost, and I had to eat the cost or try to repair the 1st one and the installation of the new one.

Insurance policy for the future

Would Recommend

I purchased this generator in July and the installation was completed in August. The installation was very professional. I would recommend One Way Electric in Phoenix for the installation.

DIY'rs?...skip the inconvenience, don't wait!

Would Recommend

Replaced name-brand, ng, 15kw mobile (shed/outside/stationary) machine w 26kw Generac. Unit was fine; not enough juice to carry both ac units @ same time. Generac resolved all issues: no going outside to start, easily carries full house load, can be run during storm, no periodic inspections during extended run times. Should've done this in the first place! Great machine w perfect financing (18 mo/no interest)!
