Rated 5 out of 5 by from Outstanding performance and reliability Bought our house with this generator this summer. Snowstorm this week. Generator has been running steadily for 6 days. Very good performance. Really like the propane engine so that I’m not lugging fuel tanks too.

Rated 5 out of 5 by from Great Quality Product Very pleased with our 20kw generac. We live in a rural area where we have saw power outages last up till two weeks. This generator gives us peace of mind with all out deep freezers full of meat. Runs our whole house just fine. I would recommend anyone that can afford one to go ahead and get one. I have wanted one for years just hated to spend the money for it. Was money well spent when im away at work and the power is off with a family is hard. Not anymore i can montior it right from my phone and look at the status. Family can carry on just like the power isnt off. Dont let anyone cut any corners on installation make them do quality work and everything will be safe. Thanks Generac!

Rated 5 out of 5 by from 20kw GENERAC GENERATOR I own 4 of these, I have the early generac to the newest. because of my job, when I am away, I do not have to worry about the power being out and I'm at work. I have had the pull start generators and they are fine in a pinch. But I do not have to worry about having to keep gasoline in a can on site at all times. The avg run time for those generators are about 11hrs or so. With the ones, which include the older one's, all are run on natural gas. No worries. They are easy to maintain or I can have then serviced at a reasonable price. Great stuff. I would recommend everyone that can, to have one installed. They pay for themselves the first time the power goes out for hours or in my case.... days. Worth the money and sacrifice. A good portion of my neighborhood has them after seeing me with lights and their were out for 2 weeks. No hotel for me and no soiled food. Thanks and I hope I didn't talk too much. Buy it!!!

Rated 5 out of 5 by from This generator has excellent features We installed this Generator to power hot water boiler and hot water tank . This will give our guests heat and hot water in case of power failure. Also if power goes out for extended period , water lines will not freeze. It gives us peace of mind.

Rated 5 out of 5 by from LOVE this Generator! We had DHM Services install (professional and exacting) our Generac and wow do we love this generator! It's quiet and dependable and I'm so relieved now to not have to worry about power outages again.

Rated 5 out of 5 by from beautifully designed! Our 22KW Guard series generator is a beauty! We needed a generator for the "must-haves" when the power goes out, which is quite frequent on our cul-de-sac. The generator matches the color of the house too! We are quite pleased with it. =]

Rated 5 out of 5 by from We now have peace of mind! We live in a semi-rural area that has frequent power outages. They aren't normally for that long of a time period, but we have well, septic and a sump pit that runs constantly, so time can be crucial. We don't want our basement to flood. Also, our main heat source are baseboard heaters, (we do have two gas fireplaces and a heat pump unit as well), so again, we have peace of mind in the event of an outage. Rick Todd and his crew from Greenfield Power were amazing, the installation went very smoothly. He had it very well coordinated with the electrical utility, the ESA and his sub-contractors. I would highly recommend them.
