    Have not installed generator yet, but did a lot of research. Staff at AP helpful in answering questions prior to online purchase. Pressure washer still in carton also. Sure it's a great product. The fact you could include a $ 599 item made decision easy.

  2. What to Buy

    I knew nothing about home standby generators before I purchased my Generac 6461 16kW from AP Electric & Generators. All I knew is that I was sick of losing power and was going to bite the bullet and get a home standby generator. Dom at AP Electric did a great job of describing the differences between manufacturers. In the end I selected the Generac 6461 16kW generator because it was the best value. I was able to purchase this 16kW cheaper than a Kohler 14kW which allowed me to power up 2 additional circuits in my house. No power outages since install but I am ready.

  3. Easy Transaction with AP

    Finally found time to write a review. I couldn't be happier with my purchase of the Generac 6461 16kw generator. First great value. You can get a 16kw generac generator for the price of other manufacturers 14kw. This allowed me to power up more circuits in my house. Installation went great. No issues ordering from AP Electric they were great. Great piece of mind.

    I have had a number of outages and this unit always performs flawlessly. It starts automatically in seconds. The Generac 6461 is easy to maintain and is a must for anybody that wants to be protected during power outages. I highly recommend this back up generator and the service I received from AP Electric.

  6. Didn't miss a beat

    I had my Generac 6461 generator installed last year. When the power went out the Generac fired right up and into action. In seconds my home was powered up. The outage lasted for three days and it never missed a beat. Thanks Generac and AP Electric. I also purchase all my maintenance kits from AP Electric. Great price, free shipping and fast delivery. No need to go anywhere else for my generator needs.

    We got this Generac 6461 generator in May 2014 with the 200 amp transfer switch. We bought it because an elderly relative who was moving in with us. There are medical machines that need to run. This is the best way to make sure that everything we need is available, all the time.

    The installer did a great job, and we are very happy. The power has been out several times since the install and it has kicked on automatically every time and kept everything running. We haven't had any problems or issues with it.

  9. Good unit, make sure you get it sized right

    Best investment I ever made. I live in a rural area outside Hayward Wisconsin and lose power often. I purchased the Guardian 6461 16kw. I had the unit installed by a local electrical contractor. He and the LP company made sure everything was set up right. He did a wonderful job. I have had my generator a little over a year now, and been without power 3-4 different times. Each time the Generac has started and powered up my home. I am so glad I bought this. AP Electric was great to deal with, and I am glad to know they will be there when I need parts and supplies.

  10. This is the one you want!!!!!

    This is the best standby generator on the market available. I have the important things in my home connected. When the generator is running my home there is no break or dimming of power. It's as if the regular electric is still on. I have such piece of mind because this generator is so reliable. Also the noise is so low that I can barely hear it running. If you are looking for a standby generator, look no further.

  11. Generator that gets the job done

    The Generac 6461 Guardian generator is just the ticket. The 100A transfer switch has just enough circuits to back up the important things in my home. This came in handy during the latest storm. The power went out, and in less than half a minute, my home was lit up, and we were warm and safe. I am glad AP Electric was so helpful in choosing the generator for my home.

    We downsized to a smaller home recently. Our previous home had a 22kw generac and it always did the job. It tested itself every week, and was ready to cover when we had power outages. The kids are gone so we did not need as large a home as we had. We got lucky, and hit an upturn in the market, and sold the old place. With some of the profits, we decided to buy a home standby generator for the new house. We called AP and talked about what we had, where we were moving and what we might need. The rep helped us figure out which generator to buy. We even got the monitor thrown in, which will be nice when we travel.

    Purchased my Generac 6461 about a month ago. Very pleased with purchase so far. It has been installed for about 2 weeks now. We have not had a power outage yet but it goes through its weekly test start-up without a hitch. I am now ready for a power failure which occurs about 3 or 4 times a year where I live. I hate to say it but I am actually anxious for one to occur now that I don't have anything to worry about. Transaction with AP Electric was seamless. Excellent tracking and communication on the deliver of my generator. Without reservation would recommend AP Electric.

    I finally reached my frustration point with being without power 3 times last year so I decided to buy a home standby generator. After talking with my electrician he recommended Generac and this particular unit for size of the house. I called AP Electric and talked with a customer support representative by the name of John. He was able to answer all my questions. He suggest that I might want to add the concrete pad that the generator sits on. I called my electrician to see what he thought about getting the concrete pad. My electrician had never used this accessory before as he had always pour concrete pads for the generators he installed. He looked at the concrete online and liked and thought it might save him a couple of hours installation time. We ordered the generator with the pad. The electrician was very happy with the concrete pad that we ordered with generators. It made the installation go quicker and as a result he was able to knock off about $480 from his bid. Thanks for the recommendation on the concrete pad AP Electric. Great and smooth transaction all the way around. Would strongly recommend.

  15. Very Happy
