I had 3 electricians come out and estimate the cost to purchase and install a new generator for my home in Springfield. I care for an oxygen dependent person and losing power is a life or death situation for us. The three electricians were allover the board with their "solutions". I then found this site: http://www.generatoralliance.org Using the best practices I found on this site I reinterviewed each contractor asking placement of the unit, installation, and most importantly: Who do I call for service or problems and repairs when needed. I was shocked to learn that these electricians could not service my investment. Yearly maintenance is apparently required but none of my bidders do that, they only the install. I cannot lose power EVER. This was a huge concern. I then called All Power Generator. From lovely lady that answered phone to the estimator who came out to my home and finally the service guys, they "passed" all my questions, most important they are on call 24 / 7 if there was a problem. I would highly recommend this firm. If you are concerned about a loss of power, learn from my "almost" mistake and call a REAL GENERATOR COMPANY. Call All Power! Thanks guys! read more
