Rated 5 out of 5 by from Great product for the cost. Small footprint made it easy to find the right location. Looks great and has a clean exterior. Noise level is good even at full power. So far the right choice for our home.

Rated 5 out of 5 by from Pleasing all the way around! I am so happy with my new unit. I almost can't wait for a power outage to have it kick on automatically and power up my house. I like the way it looks and operates. I could not be more pleased! I decided to purchase this unit after Hurricane Season due to losing power for 3 1/2 days and my portable generator just couldn't keep up.

Rated 5 out of 5 by from Best generator on the market. We do home improvements and have been involved with a few generator installations over the years. Generac has proven itself to me many times as being the most reliable, quietest and economical generator on the market. My wife and I have wanted one for years and now that we are approaching retirement, we feel it's time for ours. We don't get many power outages, it's mainly for peace of mind.

Rated 5 out of 5 by from Excellent product. Fills our needs fully. We are in our seventies, retired, spoiled with our toys and acutely aware of our potential for health and accident issues. We live in a hurricane prone region. Although, the generator is new and a long term review would address reliability, these thoughts are provided. This generator provides whole house power allowing us to get rid of several devices such as portable generators, lighting and coolers stored/used during power outages. The phones work, CELs charge. We no longer have to buy ice, buy and store gas, move coolers, hook up lighting, wire the frig./freezer to a portable generator and the TV works. It is not only a power source, it is a reason to get rid of several potential safety related functions during outages that we no longer need to accomplish at our age.

Rated 5 out of 5 by from Living in the boonies I live way out in the boonies and we are usually the first ones to lose power when it happens and the last ones to get it back, so having the peace of mind that no matter the time or conditions this beauty will come on and keep my house warm or cool as the seasons determine is money in the bank.

Rated 5 out of 5 by from Oxygen dependent We live in a rural area and when outages occur, it takes some time for the local coop to find the problem and provide repairs. I am Oxygen dependent, on O2 24/7, with limited bottle supply and for the portable concentrator, limited battery time. The 22 KW Generac Guardian provides me with a greater peace of mind during storms and winter time. Have been using a portable unit to run extension cords into the house from the garage, but that is not the best solution due to exhaust fumes. The Generac brand is a brand I whole heartily trust and highly recommend.

Rated 5 out of 5 by from Great investment for peace of mind. We live several miles from town on a farm where heavy storms can take out the power for extended periods of time. Drifting snow can block the roads for days. With aging parents, one with alzheimers/dementia, I now have peace of mind knowing that I can bring them into my home for warmth, food, and comfort in the event of an outage. I can now go to sleep listening to howling winds without worry. These things make this purchase a fantastic investment for my home.

Rated 5 out of 5 by from Great product!!! In our new home, we are totally dependent on electricity. our Generac 22kw gives us a peace of mind in the event of outage to power the whole house. And with the transfer switch, no need to do any manual thing. More, it's quiet. I would definitively recommend this. Thank you!
