Supreme Service Today was a pleasure to work with and an excellent choice. Alex gave me two options for replacing a converted coal furnace. After choosing the high efficiency unit, the installation went as planned, including the subcontracted asbestos removal from the old furnace. The work crew was polite, responsive and responsible. When the temperature decreased and it was becoming more difficult to warm our offices with space heaters, the crew stayed until after 7pm the final day to ensure that we had heat before a snowstorm was coming. Overall a very positive experience.
