"Excellent contractor. I wish more contractors were like John, the owner. We replaced both of our furnaces with York High Efficiency almost 5 years ago. They are VERY temperamental. In fact I would not get another one. However John and Allegiance are outstanding. Every single time we have an issue he is there or one of his techs. He answers the phone, returns calls and does an OUTSTANDING job. I cannot say enough good things about how excellent he runs this business and really cares about his customers. The high efficiency I am not in love with, and now we are regretting them. They are all the rage but require a great deal of maintenance. However John is outstanding as a heating, ac and plumber. If you have a need of one of his services do not hesitate to call him."
