This is my second house generator (at a new house) I will let you know when it is used for sure :)

C & D Custom was outstanding they did a job a good price

This is a product that every household should have this one is wonderful!

Having just bought an old house in the country and putting in all new plumbing and heating, we wanted to protect our investment with a generator. We have had the generator for over a year and went months with no power outages but this past summer was a different story with all the storms. When people worried about having no power, my family was confident in the generator. I did have some issues with installation however. The dealer set the battery and the coldpac kit up incorrectly leading to weeks of malfunction since the battery was dead. After I called Generac directly, the electricians fixed the wiring issue. No problems since. I like that I as the consumer could call Generac for info and assistance. This is very important for us independent Vermonters!

I have had our 20kw Generac Aluminum generator for over 5 years and she has never missed a beat. Compared to an older 15kw steel jacketed generator we had at our last home this unit stll looks like new. It has the automatic transfer switch which also has never failed us. We live in the heart of Hurricane country but I trust that my Generac will be at the ready when the time calls. Maintenance and oil changes are a snap and I could not be happier. I am thinking of installing one at a home in Colorado which also has many power outages.

In the first month the battery charging circut was found to be loose, and thus failed to initially charge the battery - easy fix under the warranty. At the 11 month point the digital display when all black - again this was covered by the warranty. I've had electrical outages about once per month - one in below zero conditions for 15 hours and another post hurricane for 7 days - every time the unit has started and run without any problems - great performance! I got the 200a auto transfer switch - it does a great job, and there is no loss of power when shifting back to the grid!

Test by workers and weekly exercise period is amazingly quiet; Not yet fully tested with load switch. Easy to check hours of run time. Some peace of mind knowing Generac whole house unit has been installed. Other family members are using this product and are extremely satisfied and I'm sure I will be as well.

We got a 20 kW Generac installed the summer of 2014 when we moved into a new home. The previous owners had one already but decided to take it. So we just replaced it with a brand new one. So far we have had only two power outages. One in January of 2015 and one about a week ago. We were so happy to have it when we lost power during the ice storm because the whole house could be heated! Also when we lost it a week ago our neighbors were without power for 3 days from just a pop up summer storm, but we weren't because we had a Generac. All of our neighbors had to leave their home to go to a hotel because there was 100+ degree temperatures during the day. We were so relieved that it our generator could run 2/3 AC units and everything else in our 5,000+ sq. ft. home! This was our first backup generator and have been very satisfied since we have moved. So far it's been great and hope it will last a long time. I just wish Generac made an air cooled generator bigger than 22 kW because they are so much more affordable then a liquid cooled and some people don't want to spend $15,000+ dollars for a liquid cooled model that will run 3 AC units at once!

Coastal Living is better with a backup power source during times of severe weather. My automatic 20KW propane-fueled Generac provides the power to run my entire home. The system self-tests once a week and hearing the generator start and run automatically is reassuring to this coastal homeowner. Working with my local electrician, Aaron's Electric, the installation and testing of the unit went smoothly. The unit was shown to provide the power to run all the appliances in my home. The power changeover to generator power takes about 10 - 15 seconds once the unit is running and outages are less than 1 minute during the transition. I am very happy with quality of the unit and the ability to keep my household running during times of severe weather. Generac power systems work well and provide the backup needed during power outages. I recommend this product for all coastal home owners.

Our 20 KW Guardian ran and provided power to our whole house for 156 straight hours. This was in the aftermath of Hurricane Laura here in north central Louisiana. Came on automatically 10 seconds after the grid died and we never missed a beat. We installed this unit when we built our house 10 years ago and it has always been reliable. We live rurally so we've had to rely on it on multiple previous occasions. The longest prior to this was 4 days after a tornado. Some neighbors will be getting Guardians soon. Just have it installed and serviced by professionals recommended by Guardian and you're good to go!
