    Impressed Home Depot Online was Flawless
    As a Electrical Contractor, I could not ask for more. Great shipping time. Price was right.

    Excellent back-up power
    We just lost power in the DC area and it ran our central AC and half our house for 45 hours straight. It worked great! (We installed it 2 years ago, so it holds up). Installation is very complicated so you need a good electrician with generator experience.

    A WONDERFUL PRODUCT
    The first thing to know is that you will need an electrical and plumbing permit from your town. Some towns actually require that you provide a property survey before the permit is issued because they want to see the proposed location. In my town, the generator had to be at least 5 feet from any property line. Luckily, I had an old survey kicking around from 15 years ago which the town accepted. I put an "X" on the proposed location and waited two weeks for approval. My Kohler 12RESL arrived by ... read more truck delivery right on time and the driver wheeled the unit to the end of my driveway. I hired a certified Kohler electrician to do the installation work, and they sent over fours guys who lifted the unit and walked it over to a gravel base that I put down the day before. I used about six bags of pea gravel to create the base. When the Kohler tech opened the box, he told me that I got a fantastic price on my 12RESL generator from Home Depot. He could not, as a dealer, match the price. You should know that model sold by Home Depot differs from the one you would get from your local Kohler Dealer in that the Home Depot model does not come equipped for internet based control. In other words, if you want to be able to control your generator while lying on beach in France, this is not the model for you. Since my budget would now allow for a higher priced unit anyhow - this one was perfect. While I considered the Generac models, I opted for this one because A) it was the top rated model when Consumer Reports tested generators in 2006; B) as an older model, the bugs have been worked out. c) The Kohler units are able to handle larger loads than comparable Generacs due to their ability to provide short term surges in power production when appliances are turned on. I would have had to move up to a 14 KW Generac model to handle my house. The Kohler 12RESL comes with a very nice 100 AMP transfer switch that allows for 12 circuits to be activated in a power outage. Even though my house has a 200 AMP main panel, it's no problem to connect the 100 AMP Kohler panel to the 200 amp main panel using a circuit breaker. I selected 12 circuits that will have my home up and running in an outage. Here's my list: 3 ton Central Air (this uses up 2 of the 12 circuits on the panel because it is a 220 volt application), Washer, Gas Dryer, Gas Range, three kitchen outlets, master bed and bathroom, room, Cable Service, Two TV's, and 2 Refrigerators, dishwasher, and lighting. Before you buy, look at your electrical panel and figure out which circuits you would select. If you absolutely need more than 12 circuits, this is not the generator / transfer switch combination for you. One of the nice features of the transfer switch is that it allows the electrician to set the central Air unit to come one 5 minutes after everything else. This is a great feature because it prevents the generator from having to deal the extraordinary load caused by starting everything at once. The 12RESL is housed in an insulated steel box and it is very quiet when running. As a matter of fact, my wife and I were absolutely shocked by how little noise is produced by this unit. After installation, we tested the unit by shutting off the main breaker. The Kohler started up and we had quiet power in about 8 seconds. While testing the generator, it ran my central air while running two refrigerators, and dehumidifier, lighting and a TV. At my electrician's recommendation, I switched out all of our old fashioned light bulbs for Compact florescent and LED bulbs. I should have done this a long time ago to save electricity, but now it's doubly important. Less wattage consumed by lighting means more generator power for everything else. Here's an important tip: The Kohler transfer switch that comes with this unit does not feature the newest technology called "power shedding." With power shedding, a small computer inside the transfer switch always monitors the load and will automatically shut down circuits that you designate as being less important if too much electricity is being used in the home. If too much of a load is demanded of my unit, the main circuit breaker will trip and the whole house would go dark. We would then shut off a high demand appliance and reset the breaker. The new power shedding technology is great, and Home Depot offers it with some of the Generac units that they sell - at a very good price. If you have a tight budget, you'll have to decide whether you want to place the emphasis on getting a better generator (Kohler) or a more sophisticated transfer switch (Generac). Note that not all of the Generacs come with the power shedding switch. Be careful to read the Home Depot package deal descriptions very carefully. Both the Generac and Kohler units require an oil change after 100 hours (4 days) of continuous operation. If you think you might have an outage longer than that, buy some motor oil and learn how to do an oil change. Based upon my research, the best oil for these units 10W-30 Synthetic Mobil 1 Extended Performance. Whether you buy the Kohler or the Generac, you should buy the optional carburator heater if you live in a place where temperatures can drop below 32 F. If you buy this particular Kohler unit, you need Kohler heater Model GM39564-KP1. Do not buy the Kohler carb heater sold by Home Depot because it will NOT fit the 12RESL model. The Home Depot web site says it will fit, but it won't. You can read my heater review for more details.

    Works well
    Seems well built and works perfectly. Only time will tell how it holds up in the weather here in NY. The installing electrician was happy with the support line, 'tho there were long waits.

    GREAT UNIT!
    My wife and I purchased this unit for our home in the mountains in San Bernardino, CA. We have had the unit since January, 2011. I have MS and I am disabled, we have chair lifts in our home and God forbid I need to be on a ventilator it would save me. The unit self test for 20 minutes every Saturday. It is quiet and really is white noise. We have had several power outages in the past year the longest lasting 5 hours in the middle of February in a huge, cold, snow storm. The generator kicked on ... read more right away and ran our whole house with no problems. It runs on natural gas so with natural gas you only get 18000 W but more then enough to run everything in our house and then sum. If you have the means and the need I highly recommend this unit!!

    Kohler whole house generator/14KW
    The power has not been off yet.I think it will be nice to not have to hook up a generator to have electric power.

    Awesome Features!
    We decided to purchase a generator after Super Storm Sandy. This generator made us so happy we did. We've had some prolonged power outages since our purchase and it has proved to be an asset in our home. We have alot of outages where we live and a generator is a must! We're so glad we chose this one, it's fantastic. Thankyou for making such a great product.

    Best move I ever made
    I use to use a 8 K welder generator to keep power running in the house but I had to be home to connect it. I travel all the time not fun getting the phone call from Mrs. I connect this up and could not believe how well the switch and generator reacted to an outage, and how it handled the load. I highly recommend this generator and switch.

    Good product
    We have been wanting to install one for a long time. We are ready for the storms! The installers were super sweet and it didn't take them no time to install. They did not leave till they made sure everything was working. Hopefully we won't have to use the generator anytime soon but if we do we are ready!

    Great product! Easy to install!
    Bought this generator after researching and studying all options! It works flawlessly! Installation was effortless and directions were easy to follow! I'm not worried now if there is a power outage, Generac has my back! Setup was easy and product is well built and american made!

    Quality peace of mind!
    After much research we invested in a Generac for our peace of mind. The 1st time it kicked on for an outage, we ran around turning everything on to "test" the unit, you will too, it performed flawlessly. You never have to think about it, but it feels good to know it's there.. READY to run my whole house.

    Generac Series installation & features
    Selected this manufacture / model after multiple years of experience with a 20K unit at a previous property. It functioned flawlessly when needed with limited maintenance. This new unit (10K) installed (natural gas and transfer panel) with little effort and started the 1st time on manual and then on auto when tested. Disappointed it was not shipped or offered with a starter battery & battery case - required to search the manual for a correct battery type / model.

    Works as advertised.
    Product arrived on time and in perfect condition. Electrician who installed it was very impressed with how easy it was to install with it's pre-wired transfer switch. Unit started right up and performed all tests flawlessly. Initial excercise of generator also ran properly. 10k generator supplies my small home with almost complete electrical service. No more worries about power outages.

    Great automatic backup generator
    After flooding our basement when the power went out while we were gone, we decided we needed an automatic backup generator. This unit is capable of supplying our whole house. It has been great to have the power go out and after a few seconds the genator starts and we have power again and no more flooding. As soon as the utility power comes back on, the generator transfers off line, cools down and shuts off. Great product at avery reasonable price.

    Nothing to complain about...
    Delivered in a timely manner (10 days) though I believe I was expecting it in around seven. I found through multiple estimates that it is cheaper to buy the unit yourself and then have it installed rather than get it through a thrid party. I finally had it installed for about $1900 which was far less than any other estimate I had been given. Unit works well... I had 2 small problems with the install but I am very happy with the product. Now I can count on the power not going out for at least a few years.

    This is our second one - great generator!!
    We recently moved into a new home and purchased this 20KW Generac. After installation the electrician threw the power to the house and the generator automatically transferred power with natural gas. We haven't had a power outage since it was installed but it is a great peace of mind knowing that our home can still function as usual during an outage. It automatically runs an exercise every week. We don't notice the noise when we are inside. We knew that we wanted this brand because our old home ... read more had the 17KW which never failed us. Found the best pricing at Home Depot.

    This generator was shipped and delivered with no problems. It was easy to install and runs great. Had a good experience with Generac customer service. They were very helpful.

    16KW rock solid
    I have had this 16KW generator for over 5 years. Hurricane Ike blew through Ohio just after install. No power for 3 days ran very well. I had other outages lasting over a week long and still no problems. It is an easy install if you are handy with gas and electricity. You need friends to move it to the pad.
