Rated 5 out of 5 by from Our Second Generac Had one installed in our previous home. Didn't think twice about getting one when we purchased our new one. Wouldn't want to live in a home without one.

Rated 5 out of 5 by from Generac Generator Gives Peace of Mind! I am so relieved to have a whole house Generac Generator! This purchase offers peace of mind from losing heat in the winter, air conditioning in the summer and electricity. K & B Energy Solutions gave me excellent customer service. The installers were polite, conscientious, and gave attention to detail. I appreciate quality workmanship, so I am highly recommending K & B Energy Solutions!

Rated 5 out of 5 by from Very professional representative Metro Electric in Romeo, MI did a great job installing our unit. We have only had one power interruption since the installation was completed and the generator worked as designed.

Rated 5 out of 5 by from Love the cold weather option and sleek look of the unit. The Spring City Electric installation crew did an outstanding job. They were very professional in their approach and kept me informed throughout the installation process. The entire process took less than a day to install. Now I'm ready to tackle my first power outage! :)

Rated 5 out of 5 by from Peace of mind with a Generac Just had the Generac 18KW GUARDIAN-NO T/SW AL whole house generator installed yesterday. Haven't had a chance to see it in motion, but it gives us great peace of mind knowing that should our power go out our home heating and sump pump will continue to work as needed. we plan to do some traveling so being away from home at times we won't have to worry about a flooded basement or food in the freezer going bad if the power were to go out. I also need to mention the added value to our home should we decide to sell this house. Having a generator adds extra value. Thanks Generac.

Rated 5 out of 5 by from No more worries about power outages! After waiting for about 8 months for supply chains to start to catch-up after Covid I got my generator and got it installed last week, now I’ll sleep better knowing that I’ll always have power no matter what happens in this crazy world. The generator looks awesome and is really easy to use and maintain, I can’t wait for a power outage so I can test it out!
