  1. Briggs & Stratton 4039CSA 20Kw

    5 star rating Product Review Rating: 5/5

    Posted by on Apr 06, 2015

    I absolutely love the Briggs & Stratton home standby generator that I purchased from AP Electric. I did a lot of research before I purchased the unit. Once I completed my research I called AP Electric and asked even more questions. They made me feel very comfortable that I was making the right decision. The generator arrived within 2 days from placing the order. This was much quicker than I expected. I waited to write my review as I wanted to see how the generator performed. The generator is performing like a dream. We have had 3 power outages over the past 6 months and the generator has performed flawlessly! I would highl recommend this Briggs & Stratton 20kw unit.
