We learned from our Ductworks guy "Mario" that our ducts have never been cleaned in the 30 years that our home has existed. He proceeded to show us footage with his camera of before and after. We just moved in so it meant the world to us that he took care of us the way he did. Mario is a very personable person and it's obvious he cares about his job and his customers. I will refer Ductworks and make sure to tell my referral that Mario is the guy to ask for. The cold is around the corner and we are thrilled to use our furnace with no worries once we need it.
