Our 22KW has been installed a few months and already run a bit over 60 hours so enough use cycles have been experienced to let me recommend this unit to anyone looking to protect their home or business from periodic, even frequent, power outages. The only points keeping me from providing an unreserved five star rating are these: The unit looks fine: functional and solid. It is loud! Focusing the noise away from your house/business should be a consideration in placement. (Probably many generators of this size and construction have similar issues but I am more aware now!) The whole house transfer switch is critical and buying this as part of the generator bundle is a great value. No matter who you choose to do the installation (from DIY to independent contractor to Generac Recommended), be aware a proper installation requires expensive wiring; potential ground excavation; and a very competent electrician comfortable in all aspects of electrical wiring; general contracting and local building codes. This too is something any generator/transfer switch install will require, but be very aware installation can be a SIGNIFICANT cost of the total project. Finally, I don't have the add on unit which allows internet alerts (I am considering this additional expense), but I think it would be very convenient. The unit functions with minimal maintenence and has smart diagnostics, but being alerted remotely would be a real plus. I think this functionality should be built into the unit in today's age at some marginal added cost. (Adding this to every unit should bring the cost down to almost nothing for the manufacturer.) Overall, very pleased with the unit, build, design and value. Were I to make a purchase again, I wouldn't hesitate to buy from Generac. (In my location and situation I would/should have done it sooner!) I actually overbought for my situation. My home would likely work fine on a 16 KW, but on advice from knowlegable friends, it is always better to "overbuy" and not tax the generator than risk running at 80-100% capacity on full normal load. There are also some benefits to certain units. Shop for your needs now and in the future. This should be a great long term investment in your piece of mind and your property. Good luck!

We are very pleased with our Generac generator. It was installed in April 2017 and by the end of May we had already seen the benefits of our Generac 3 times! It is quiet, and the switch over from normal to generator is seamless. Great product - so glad we purchased!

The Generac installation was a matter of eliminating the potential for another long-term electrical outage as had occurred 18 +/- months ago. I have every confidence that the device will function when it is needed, although the need has not occurred since it was installed. It was a matter of not wanting the inconvenience or losses from an electrical outage when I could afford to prevent it. With the device auto-starting weekly, which is not offensive to my home's community, I feel assured that I have done what's necessary to maintain my home and lifestyle regardless of the periodic failure of my local utility to provide power 100% of the time. I am sufficiently satisfied such that I am in the final stages of installation of an identical unit for my "other" home where my son and his family live. The idea is to have it and not need it instead of needing it and not having it. It is a lot better than having a portable gasoline-powered generator which must be connected for use if ever needed (especially when being away for long periods might preclude the ability to re-power the house).

I had my generator installed a few months ago. The transaction was top of the line. From the Owner (Russell) to the installer's, completely professional and courteous. Last week the main power went out and within seconds the generator automatically did exactly what it was supposed to do. Now I have the peace of mind knowing that even if I am away from home, my home will be supplied with power!! Great investment!!

We are happy to again have a full house generator at our new condo in New Hampshire. It provides the security we wanted. Leblanc' did an excellent installation and fully explained all its features. We have not yet needed it but I am sure it will operate flawlessly when we need it.

Having a Generac Generator is total peace of mind. Within 4 weeks of moving into our new home someone caused an outage in the area. Within 3 seconds of the power going out my Generac Generator came on and restored all electricity to home. When the electricity was restored the generator shut itself off. I no longer worry about the power going out in the winter.

We had this 22KW automatic standby generator installed about 6 weeks ago and it's worked reliably during 2 recent power outages in our area. It's fairly quiet when running and is fully automatic, including the weekly "5 minute exercise" period. We love not having to worry about losing heat, stuff in the frig, etc. when power goes out in our area, which happens often.

I have wanted this for years. Recently moved to a wooded rural lake home and didn't want to risk losing power. Not there full time and didn't want to lose frozen food if the power should be interrupted. I have also been without power due to ice storms in the winter. No longer an issue. Peace of mind is worth the cost to me.

I live in a rural area in Costa Rica and installed the two generator I purchased, with the help of a friend. The installation instructions were clear - and the generators are functioning perfectly when our frequent electrical outages occur. I am a happy customer!

As whole house back up Generator there are several Brand Choices. Generac has priced it right the Unit. Truly so far has not seen in action during Power Failure in past several months since installation. Weekly checks are not noticeable. Remote monitoring is surely an advantage with solid warranty and reputation.
