Brian was awesome.
He jumped into this and quickly determined that the issue was a failing pressure switch, and not at all the controller board that Empire claimed had failed. In the process of replacing that switch (and fixing the problem) he also cleaned out the main exhaust duct, and cleaned the burners so they now look brand new! This reduced the motor amp load from 9.x to 7.x, which will reduce power consumed and no doubt extend the life of the motor.
He was very professional, thorough, and demonstrated the Air Alliance honesty and trustworthiness that I have learned to appreciate very much. I was surprised to learn he has only been with Air Alliance for a few months. He represents you well.
Thanks for being my HVAC partner in business, and for our residential work.Bill,
