Addarios was referred to me by National Grid. Nichole sent an estimator right out to the house and he gave me the price right there after a complete explanation of the type of equipment, benefits of converting etc.. Nichole took it from there, scheduled an immediate installation and made sure that everything went according to plan. The installation team, Joe, Nick and the rest did a great job, handled everything including city inspection. Joe came back a few days after installation to fine tune things and go over the systems with me. Overall, I was very pleased with the way Addarios performed.
