No more flooding basement!

We have our basement trenched, along with 3 sump pumps. The last time our power went out, our battery backup pump ran until the battery exhausted itself. When we got home, I opened the basement door to about 5 inches of water. I fired up our portable generator and plugged in. All pumped out after 25 minutes. Works fine...BUT YOU HAVE TO BE HOME to do this. I researched whole house generators and GENERAC was the best. I now have my own. No more flooded basement plus I don't have to worry about it anymore!! I should have put one in several years ago. I'm a believer!.

An absolute dream

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.

Love our new generator

Installment was not difficult. Features are well defined. Manual not hard to read but does require someone who is knowledgeable in the electrical field, not a novice. Price was very reasonable. power went out 3 times while we were waiting for it to get hooked up. we were glad then that we had purchased this unit.

Excellent support team supervising installation

Very impressed by the support team, Mariposa Electric from Lindsay, Ontario for myself, who gave proper assistance in the initial determination of need, and then the installation. Machine is great, only quam is that the machine does not have decals on back (for me the front) of the generator

22kw Generator

Spring Generator did an excellent job installing our 22kw whole house Generac generator. We were pleased with their company. However, when they first started the generator, the engine malfunctioned and blew a hole in the case blowing out the oil. The unit had to be removed and taken back to the shop. Generac took a few weeks to supply another engine to Spring Generator so they could re-assemble it. It is working fine now but will need to watch over time.

Very good unit - ran my whole house through Hurricane Harvey

Had the unit installed just before Hurricane Harvey hit Texas. The automated transfer switch is a blessing. When the power got knocked out at 2:30 AM it kicked in immediately. So responsive I didn't even need to reset the timer on my coffee pot or alarm. It performed perfectly for over 32 hours. We run on propane and followed our propane suppliers recommendation to increase the tank size to 500 gallons

This product has the reliability and service that is vital in Louisiana during hurricane season.

I bought this unit to provide comfort during our frequent power outages in our neighborhood. I also bought it so that my home can be a place of refuge for my five small grandchildren during a hurricane. It has the automatic features for turn on, maintenance monitoring, and weekly test runs. The WiFi monitoring was a requirement for me. Another key was our provider who has a great reputation for quick, responsive service.

Great streamlined product with great features!

Size of product is really nice and very streamlined for the area of placement. Really quiet when running and very high quality! Added benefit of WiFi connection is important so that any problems are easily known. Weekly test is a plus!! Very pleased with our generator and a great value too!

Excellent features for whole house generating system.

we purchased the 24KW system for our home. we have well system,AC, along with multiple applying needs in country setting. BRE Electric sold and installed our unit at the best possible price, and they were very prompt in installing our unit once all inspections were performed. BRE Electric was a great contractor to work with and highly recommend them as an installer for your generator needs.

Happy owner.

I had my 22kw whole home generator installed 12/8/2016 and now I have no fear of an extended power outage. This is the time of the year that we have most of our inclement weather and the forecasts don't seem to bother me at all now. The installation process could not have gone any smoother. The whole generator is smaller than my outside central ac unit. Thanks for a great product.
