    I have a neighbor with a frequently advertised brand of Generator.
    My new Kohler impressed him compared to the one he purchased.
    The Kohler is quieter, starts up faster and has a smaller foot print. He even asked me if I paid extra for the aluminum body.
    It pays to shop around.

  2. Good brand but...

    Remember, this is only a backup generator, meant to run for hours, not days or weeks. Being air cooled and running at 3600 RPM’s, it won’t hold up if you have a long term power failure. I had this problem when we had a two week long power failure. Even though I shut it down and did an oil change half way through, the generator now burns oil and doesn’t always start on weekly exercise cycles. If all you feel you need is occasional short term backup power, it’s ok the price.

  3. Great generator, simple install

    Bought here and installed myself. If you have ever done any electrical work like wiring a breaker box etc, it is easy to do. I poured a 36 inch square slab to sit it on. Ran wires and had all conduit ran into basement prior to ordering. Once it arrived, which was right on time, hooking it up was easy to do. Plumbed in gas, hooked up wires the started the swap over to the transfer switch from my main panel. I took my time there, neatly building panel, marking wires, etc. Generator fired up like a charm. Ran a test with several items in the house on and it started my AC unit with barely a change in the sound at the generator. It has ran it's weekly tests as scheduled with no issues. Do some research and you can do it yourself. If your not comfortable, then by all means get an electrician or an installer to do it. Saved money by ordering here due to no sales tax charged.

    Kohler 12RESVL was bought and delivered. Great air-cooled generator for my home. Hope to never need it, but have it as a back up generator for the home just in case. Thanks AP electric for the help.

    I am very happy with the purchase of the Kohler 12 KW generator from AP Electric. Buying something that big and pricey from a place one knows only the most basic information really takes a leap of faith. But these guys really delivered outstanding service at a fantastic price. I have already recommended AP Electric to two friends who will buy generators.

  10. Fast shipping
