Professional interaction with installer, Spectrum electric. They know the Generac product and how to install it inside and out. Only one instance of power outage since installation. Generator performed perfectly for approx 1.5 hours during outage and kept house comfortable including heating units operation. My only complaint is that the unit is noisier than expected and location between houses amplifies the noise during operation.

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 utility company advised me of a short shut down that was going to occur on the same day my wife was coming home from foot surgery. She is also handicapped and uses an electric scooter outside the house and a small indoor scooter and a walker inside. I had planned for some time to put a small generator in. This event forced my hand to act quickly. I still do some business travel and felt I need full system protection and not just a small generator for emergency purposes. Adam from Left Coast gave me estimates for various equipment choices, we settled in on the unit I purchased capable of carrying my whole home power requirements. The staff had my unit installed two days later, in time for the planned power outage the evening of my wife's surgery. Everything worked perfectly, power came on as scheduled, and as main utility power returned cut over efficiently. The unit is planned to test itself for 5 minutes every two weeks and has done so, on time, every time. We couldn't be more pleased. Thanks for a "top of the line" DEPENDABLE product.

We are a small skilled nursing home and for years had relied on a portable generator to provide basic power during power losses which are rare. The problem was it required some knowledge to start and use the generator efficiently with as little time as possible after a power loss. With staff change overs this became a problem thus our decision to upgrade to a GENERAC automatic unit. We are very satisfied as is our local fire chief with our new equipment.

this unit was a replacement for a 18kw generac , it only lasted for less than 500 hours less than 8 years old. current one 22kw on its first weekend run, it started to have a slight surge. found the air filter had to much fire retardant on it changed out for new now its ok. hope this one lasts longer!

Electrical and plumbing subcontractors were "hackers". Couldn't predict when they were to be at my house to do their work. Left gutter downspout in an ugly and rediculous work around. Took 2 weeks to get them back to fix downspout.Plumbers routed gas pipe with whatever fittings they had on the truck leaving the pipe as an obstical and trip hazzard.

Living where power goes out often, it is much easier going to sleep or leaving home knowing this machine has my back. It does it's routine check once a week letting you know it's fine and has a green light that lets off a soft glow I check for out my window before turning in. A great investment.

Purchased at the right time,researched price,quality and performance ..picked Generac and experienced a power outage for 5 1/2 hours. Transferred over and back without a hitch.(mother in law was home and didn't notice anything). One of the best investments i ever made.

Generac system delivers power as advertised. System comes on within 3 seconds of power failure, runs my entire house and shuts off automatically when electric is restored. I appreciate the weekly system check that the Generac generator performs. I keeps me and my family assured that we will never again be without electric power.

Since installing the generator we have had 3 power outages. It is so much better to have an automatic turn on with enough power to run everything. Also with a service contract we do not have to worry about taking care of our generator and it will always be there when needed.
