Peace of mind

The unit works very well, and it has provided service several times when the electric grid failed. It provides us with a great feeling of safety and peace of mind.

24KW in Ohio

Everything works as planned. My install was April 2025 and I just had an event in March 2026 where the unit ran for 24 hours consecutively. No issues. And very little oil usage. My recommended installer is 5*.

Generac Home House Generator

I recently purchased the 18k whole house generator due to the recent weather events and various power outages. I like the Generac reputation as well as the warranty.

I love the automatic start!

I have had it running for about year and a half, I do like the generator in general, starts and switches very smoothly, and shuts down once power comes back up very well, great protection. The App I have not been able to connect to generator.

Peace of mind

Bought my Generac after an ice storm and a tornado. We have only had to use it once since it was installed. Knowing I can heat and cool my home as well as protect my pool pumps and hot tub equipment from freezing is well worth the investment!

Peace of Mind

I had this installed the end of March and have already had one brief power outage but the generator started within 2 minutes! This is truly peace of mind.

Works great

I bought this last year and the electric has only went off twice. Both times, the generator was running in less than one minute restoring power to my whole home. That gives me the best piece of mind for power grid emergencies.

Best Ever

Bought this for peace of mind. Best investment ever, two days after installation a snowstorm knocked out power and my family never knew. Licensed installer did an outstanding professional job. Shout out to Dynamic Generators Sales & Service

Happy With My New Generac Generator

I am very pleased with my Generac generator. The sales, installation and support processes have been stellar. I feel very confident that when the power goes out that we will be protected and safe with our Generac generator.

Great Product

I purchased this generator in 2024 because I work out of my home and need access 24/7. This generator has been great. No issues at all up to this point
