First of all, Mike spent a lot of time explaining our options after he saw our house and its set-up. He had no problem reworking the estimates on a couple of different systems. Mike did not try to push the most costly set-up either. He pointed out that in an emergency situation we really did not need to have everything tied in and then proceeded to identify the key elements which we might include. We were given an initial waiting time which we were happy with, but, a unit became available sooner and Essential Power Systems gave us a call to see if they could do the install the next day. They arrived on time and each member of the work crew set upon their individual tasks in an efficient, and professional manner. The workers were courteous and affable. They did not mind questions about their specific duties and were open to friendly conversation. They did not mind our dog, and our dog accepted them easily. Our grandchildren were also visiting at the time, and the men glad to let them see what they were doing. these guys have obviously worked together for some time. It was as if the installation process had been choreographed. They were considerate of the landscaping near the install. When the install was finished they performed a check with the generator running to verify each of the circuits connected were as expected. Then they gave us initial instructions for the operation of the generator. I would also like to add that I had a number of questions both before and after the install. The staff at Essential Power were always able to answer my queries, and were prompt whenever a call-back was required. I can't imagine why anyone in the service area for Essential Power Systems would go anywhere else. Product, Price, Performance, and Service, they have it all. Wappingers Falls
