I've always been impressed with Generac generators, so they were my only desire when we were financially ready to purchase a whole house emergency generator. We have a DD/ID adult son, so having one was important to us for his sake.

This month will be 1 year since activation of the unit. Expecting the installer to contact us for maintenance, but so far, nothing. Maybe they will contact in the coming weeks of May.

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.

Bought this a month ago and so far I'm fairly satisfied. Have had a couple of problems with it and still haven't received in paper my paperwork for my 10 year warranty

New generac blew oil and then just quit

We paid over 10 grand just a year ago for brand new generac. It's only ran for 5 minutes at a time for its weekly test. We lost power 4 days a go. The generac kicked on and has ran solid. We haven't used much power. Mostly lights and fridge. This morning, the generac just quit. Went to check it out and it has blown oil out the side. They say our power is still a day, possibly from returning. Called generac and they can't get anyone here for at least 3 days. I'm very disappointed and sickened that we spent well over 10 grand on this product. I don't feel at all comforted ,now, for having it for emergency.

Peace of mind.

Saved for 10 years to buy this, staying in our home as long as possible. We lose power frequently. Would be a selling point someday.

It has started every time we needed it. That's why

I bought a 26KW 5/11/24 It has started for me at least 6 times we have lost power. Most times it was for 2 or 3 hours. Once about 8 hours.
