I was very, very pleased with it, and it takes a lot to make me happy. They did the dryer vent. I've been here for seven years, so I thought I should get it checked. I chose them because they had done some work in another section of our 55 years old and up community. They all seemed to be very pleased with them, so I called. I think everybody was pleased with the company's work. I'd give them an A because they left the laundry room just the way they found it. I was very, very satisfied. I didn't see a lot of dirt outdoors, and they said that I must have been using my filter very well. I was very pleased with the way they handled it and their personalities.”

They came out when they said they would, and the price was what they had estimated—it didn't suddenly jump $100 when they were done. They did really great work. It was very professional. We've got to do it every couple years—it's like going to the dentist. I would give The Mad Hatter an A.”

They were just very neat and very professional; I would absolutely give them an A.”
“I went to Mad Hatter and had a positive experience there. What stood out the most was that they took the time and explained the step-by-step process in detail. They even identified areas outside of their normal, day-to-day job that I might want to take a look at to get certain things serviced to get better efficiencies for my air conditioning or save me electricity. It had nothing to do with my ductwork, but since they were knowledgeable in my area, they went above and beyond to share their experiences.”

I would give them an A.”

I had gone off in the summer, and the person who installed the floors coordinated with them even though I was in Rhode Island. When I came back, I could tell a difference in the air quality in my home. My vents had been dirty. That's the only time I've ever had them cleaned. I'd rate Mad Hatter an A.”

I had my air ducts cleaned by Mad Hatter about three years ago, and I have them clean my chimneys too. I think their service is great. I've used them for 20 years now.
