Prompt and superior service. We have an old Day & Night forced air heating system. It was making a knocking noise when turned on. We were sure it was the motor and would cost a fortune to fix. The serviceman looked at the blower motor, said that it was, most likely, that the parts holding the motor had loosened over the years and just needed to be tightened. He was honest. He didn't try to sell us a new system. Craftsmanship... a rarity in today's world. We will definitely call them again. Mimi, Thousand Oaks, California
