In Oklahoma, tornadoes are frequent. Had one August 7th, lost power. After about 20 seconds, heard the Generac fire, everything lit up, two 4 ton AC's, double oven, 3 reefers and all lights. You never know til you need it and it worked flawlessly. All my neighbors were in awe! Every home I live in the future will have a Generac! If you like the video I can send you a higher quality version.

The product was everything it was purported to be. Very satisfied with Generac, have a 12000 watt generac portable for on the job backup also. However be careful who you purchase from. Norwall power systems. uploads your order stating that additional shutoff switches are required (2) due to NEC Requirements. Additional costs $35 ea. For a total of $70.00 When shown that their rep. was in error, after delivery. you are told you will have to pay return shipping and an additional 20% restocking fee, with pictures and additional stipulations that are not consumer friendly. Read their return policy. there is no customer service.

My First Generac was a portable 5500K, which I used for 15 Years, I gave it to my Daughter and Son in law who are still using it when a power outage occurs. I graduated to a Generac 22K whole house with automatic transfer switch. It uses my house natural gas for fuel. Works as advertised, comes on within 8 seconds after loss of utility power, and then without delay or interruption, transfers back to utility power when it is restored. I am notified by email and instant message regardless of where I am located, when my generator is running or may need maintenance. No worries when I am gone for three months in Florida. It is programed to run / exercise each month, and I manually run it with a heavy load, 4 to 6 thousand Watts quarterly ie: oven, air conditioner, refrigerator, lots of lights. This is the best insurance I have ever purchased. Large purchase but great peace of mind. Quality product and great product support.

We thought the process to install gas and electric and the unit itself was well thought out. When running, we were surprised it was not as noisy as we expected. It looks good positioned behind shrubs to cover it from view. Nice tall slab to mount it on takes away any fears of flooding affecting unit. I recommend the Generac unit. I now feel secure I will have power in case of freeze or hurricane.

Unit works great on Auto mode. My biggest complaint is that after repeated attempts to get the Mobil Link set-up between my cell phone, the generator set, and the automatic transfer switch, it is still not able to communicate with my cell phone. To me, this is an absolutely worthless feature and is probably hundreds of dollars (that I paid) that was needlessly spent. A feature that doesn't work easily and intuitively isn't a feature. I have given up on trying to make this work. Generac needs to send someone to my residence and get this working for me.

Budget Electric came out and did an estimate and answered all of our questions about the generator and the installation. They gave us an install date and were on target with that date. All of the workers were professional and coureous. They did an excellent job of installing and spent time answering all of our questions and demontrated maintenance tips and operation of the generator. We did not feel rushed and appreciate the quality of work and the support that they offered. David and Dorothy

It was installed in a timely fashion. The crew was on time. They cleaned up afterwards. I was very impressed with their knowledge and skills. Generator looks great. It’s quiet. Runs strong. The only downside is that bright green light when it’s dark. So much for being inconspicuous at night. Lol. I highly recommend this product. Actually I already have to 3 neighbors. Thanks to everyone involved in making this happen.

We had the Guardian 22 kw generator installed a few weeks ago. It is completely automatic - utility power goes out, generator power comes on - utility power comes on, generator power goes off. It is attractive, quiet, and easy to program. I can't wait to see it operate under actual no power conditions.

We just installed the unit. Test results were good, not able to give 5 stars yet as unit has not had a chance to perform. I’m confident that it will be fine. Was able to get good pricing from local retailer, with added rebate. Professional installation went well. Am very pleased thus far.

We just had our start up for this unit. Everything went very smoothly. It is so nice to own a product that is built completely in the USA, it is not often you find this. We now have peace of mind knowing that we will have power going forward and not worrying about rolling blackouts anymore.
