Just wanted to drop you a quick note to thank you for the great job installing our new generator. Scott was fantastic! He sized everything up and then spoke with us about options. The Power management features on our new 20KW generator allowed us to put the entire house on the generator, rather than selected circuits. When the recent back to back snow storms occurred we lost power and everything came on perfectly! I would highly recommend you and Scott to all my friends and family! Mike K. Allentown, PA.
