Electrical Systems Of Maine

The technician notified us that he was on his way. He arrived shortly after, introduced himself and mentioned that he had serviced our generator the previous year. He worked quickly and was very thorough, performed the checks and let me know that the battery was weak and asked if I wanted to buy one and install it or he could supply one and quoted the price. I told him to go ahead and replace it. This is the second house we have had them install a Generac and have had excellent service and a very reliable generator. Customer service is excellent from sales installation and service. I have recommended them to several people and they have been as satisfied as we have.

ESM called me to schedule the routine maintenance (that had been in my mind). They were flexible and accommodating in the scheduling. Good communication and confirmation. Arrived on time. Explained what he would do. Warned us when he needed to shut off the power briefly. Cleaned up and went on his way. Price is reasonable for what needs to be done and the expertise required. I would highly recommend ESM.

Ryan Greene the technician from ESM was great. Came to my home to service my Generac standby generator. He was friendly, helpful and knowledgeable. He was in and out quickly worked neatly and did a great job!

Outstanding company, without outstanding service! The first few years I owned my Generator, I was told I could only use a certain vendor for maintenance. They seemed overpriced, very pushy with up sells, and did not provide adjustments to my machine. I searched out an alternative, and was able to find this company. The technician not only provided maintenance, but made proper adjustments that the prior company failed to make making my generator run, more efficient in fuel consumption, as well as idling properly. The next year I needed maintenance, I googled them, and unfortunately, a competitors name that is familiar came up first. When they came out for maintenance, I knew right away it was not the same company, And their price was twice as much. Since then, I have done more searching,

ESM was fantastic from the beginning. They were quick to respond to my inquiry for a generator, they had availability for a site visit allowing an estimate to be generated quickly. Dan was very thorough, offering a couple of options, each with an estimate. Mary Ann worked on financing as well as scheduling with CMP, doing all the heavy lifting for me!! Installation was timely and well done, great crew, respectful, curtious and complete. And just in time for the holiday storm and power outage!!
