    D&T Heating and Cooling is so easy to work with. You get a real live person when you call! The service technicians are friendly, efficient, and know me by name and know my system. The maintenance contract is great and gives me piece of mind.🙂

    The technician was on time -he went right to work to do seasonal upkeep on the air conditioner he was very diligent and honest regarding a possible freon leak he suggested since it was end of summer to wait and check it again next spring i like the fact that he didnt pressure me. I will use this company again.
