At first I was suspect with all of the bells and whistles of this generator, but last fall and so far this winter, it has kept my home functional and safe from intruders who prey of power outages. I have discussed this generator with my neighbors, they too plan on buying one.

Overall a very good product and value. I installed it myself and the process was straight forward and intuitive. The only recommendation I have for improvement involves access to pulling and termination of the power wiring. I installed the 22KW unit - largest in the series - 100A wire. Based on the conduit opening size and location, pulling this size wire and landing it was not an easy task. Making bends where it entered the unit in relationship to the internal equipment shrouds located nearby was quite difficult and routing the wire to the termination points requires a contorsionist. Otherwise, this is a nicely designed unit.

We live in a very wooded suburb of Boston. One might think that living 30 minutes outside of a city isn't the type of place for power issues, but our town is densely wooded with lots of tall mature pines everywhere. Whenever there's any kind of storm, be it a thunderstorm in the summer, a nor'easter or ice storm in the winter, we lose power almost guaranteed. The power company in our area is also extremely slow to restore power. Any outage guarantees at least 12+ hours of downtime, with many outages lasting 2-3 days. We got tired of spoiled food, no heat, and just huge headaches. We got this 18kW Generac 7226 installed by a local dealer last year, and it's already gotten us through two multi-day outages. It's so nice to not worry about our refrigerator and our heat in the wintertime anymore. We're able to continue our daily lives as normal while it just hums away outside powering our house. The automatic transfer switch takes care of switching back to main power after immediately once it's back, even in the middle of the night. If you're on the fence, go for a Generac. You won't be disappointed.

This was the best money I’ve spent to protect my home ! Colonial Generator was very proffesional with the installation and the workers were very knowledgeable about this product ! I am very pleased with choosing a proffesional installer and would recommend this product and Colonial Generator to anyone ! You can’t get any better !

This unit is automated to work as it does each week on a test run.. We have peace of mind just knowing its ready to serve our entire dwelling needs for us.. No individual effort needed on our part for the backup.. Its a great arrangement for us.. Thank you, Generac..

Had some Issues with a bad hunting problem with the motor after the unit was installed , it took several return visits from the installer to get it to run smooth , it has been two months now and it seems to be running OK on its weekly run , other than that I like it

I am quite pleased with the generator, although we haven't had to really use it ,it is nice knowing that it is there ready for us. My wife had not heard it run yet so I informed her that on Mondays it runs a self diagnostic test, so she she grabed a lawn chair and sat outside to hear it run when it started her first comment was that she had expected it to be a lot louder than it was. Thank you for the great product and the very qualified installers. P.S. my neighbors are jealous.

My Genera was installed a couple of months ago. It's too early to give recommendations because I just don't have appropriate information to provide anything useful. That being said, so far, so good. It reliably does it's weekly test. But the reason we purchased a unit - power failure - has not yet occurred.

The new generator came to the rescue almost immediately after installation. The power went out and the generator came on and we did not realize it right away because it runs so quietly. Then during the severe weather our power was out for several hours and we were the only family with lights and all the other amenities in our neighborhood. Wonderful!!!

We have only had Generac backup generator a few months. During that time we have had some power outages. The power went out and within 5 seconds Generac back up generator started and ran just as promised until the power returned (close to an hour). We are reminded of the Generac's presence every 3 weeks when it tests itself by starting up and running for about 5 minutes. That is a reassuring sound!
