Successful Generac Generator Purchase

Rob LaMaster, the Generac dealer from whom we purchased our Generac Generator, was simply terrific in all aspects of of his pursuit to provide us with this product, and guided us with care and knowledge. Rich Sternberg

Dependable

This is my third move in the Province of Alberta in the last 12 years. In each of these premises, a Generac was installed. They are reliable when needed.

The Generac I have now is not dependable

I bought this unit in 2024. The wifi had problems connecting and it would not stay connected. The engine blew the side out oi it with less than 24 hours run time. It took Generac over a month to get the engine replaced.

Mobile link features

I’ve had my Generac for a month now. And we have had a couple of power outages and the generac kick right in just what’s needed. So far I am happy with purchase. Hopefully a year from now I’ll be able to add more of my experience.

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!

Storm Protector

We bought this 22kw about a year ago as our 20kw oil pump failed during a week plus ice storm running 24/7 continually due to extreme trees/down/ice power outage. Had no choice but to replace. We live in Northerm Michigan and Generac IS A MUST!

Zero product quality

The motor is cheap and defective with zero product quality. The motor leaks oil, continuously tiny drops. We have low confidence in the maintenance provider. My friends have had similar issues. Profits appear more important than product quality.

It simply could not get easier to work this Genera

I cannot believe the peace of mind that this Generator has brought. I grin every time it kicks in. I've only had it a couple of months and I've had the free power outages in that period. That is why I've got this and boy am. I glad I have it.
