Peace of mind
From the moment our Generac was activated we felt immediate peace of mind. We no longer need to worry about losing power and being without air conditioning or losing everything in our refrigerators. Noise from the generator is minimal.

Great features
Very nice generator package, it is very quiet and easy to operate. Maintenance will be an easy task as every thing is very accessible.

Very close recommend vs no recommend
Thermflo/Zonatherm did an A+ job of installing and activating this replacement for my 20K Generac from 2007.Biggest issue is Generac changed the color codes of the wiring 12V Red is now 12V black on the RG027, turns out 12V on Gen is + (plus) not - (minus) transfer switch matched 12V Red to generator. Makes no sense for Generac to change color on a positive lead to black. Also confusing 240v sense having two posts for each L1 and L2 caused tech to plug L1 and L2 from xfer switch to what appears to be pin 1 and pin 2, however, it's really needed to skip a pin, but, no label on the generator. This caused a difficult to find near 5pm fuse set to blow in the transfer switch. Lastly I called Generac about the home 10 yr warranty promo before I ordered the generator, they said only the cheaper air cooled are included, IMHO misleading advertising and no offer from Generac to provide a warranty discount. Makes me think they don't believe in their higher end products.
The above said, runs much quieter then the 3600rpm 2 cylinder I had before and installation company does GREAT work to make up for Generac's lack of detail and concern.
So... if you buy it make sure you trust your installer. I'm much more tech savvy than most as I run Data Centers with 600K units in parallel. So, I feel confident in my assessment of the Generac shortcomings and the skill of the installer to overcome them.

Super satisfying unit.
Works like a charm, so quiet & dependable. Unit hardly notices when AC kicks on. Low speed, liquid cooling, this unit should last a lifetime.

Performs as advertised
For having a large unit outside house, this unit is great in appearance and blends in nicely to house. Not as loud as I thought it would be either.

This product performs as advertised
Everything was as expected. Initialization was excellent. The only issue I had was the cost of the 5 yr maintenance plan. I hope I am not disappointed with a plan that cost over two thousand dollars. It was kind of quietly inserted in at the last minute. Makes me a little wary of any new Generac products that may be coming to appear.

This product can run the electric for our house and barn
We purchased this unit to run the electric to our house and barn after Hurricane Irma last year, during which we lost power for weeks and could not pump water from our well for drinking water or bathing, not to mention running air conditioners or a refrigerator. Highly recommend contacting Jon from One Stop Generator Shop for whole house generators, and we really appreciate Rich and Matt who did excellent installation job. Oscar the gas hookup person was very good as well.

Excellent over all.
Small, compact and fits well in the selected space. Liquid cooled, low RPM, with noise no louder than large AC. Fully supports the full house with 3 AC units.
