Very personable and responsive to customer needs
Fantastic experence. John is the consumate professional and truly a very nice and knowledgable man. A pleasure to have him work for us. Always keeping us informed as to the particulars of our standby generator install and always on time when promised, he surpassed every other service and equipment supplier we have ever had working for us. Do not even consider doing a project like this without John.
I could not have made a better choice of a company to purchase and install my standby generator from . From the day I called for a quote for a standby generator to the time it took to complete the installation (about 3 weeks) everything was done in a courteous and professional manner. The work was faultless and the cost was less then I had anticipated.
John was prompt in answering my initial request for an estimate, product information and time and price quote. He is always on time when he says he will come. Very knowledgeable about his area of expertise, that is his electricablity experience and prompt installation of the Generac unit. He is very patient in going over the working of the generator, care,use,and maintenance. I would not hesitate recommending or using him again myself.
Very professional .

Flush mounts, pendants, chandeliers — hung on existing boxes.
