I have been doing business with American Specialties Insulation since 1994. Since that time till today I have used their services for duct-work insulation and piping insulation. I worked for Central Air Conditioning Contractors, Inc., in Columbia, Md., R.M. Schmidt, Inc., in Westminster, Md. and currently at Dave's Mechanical Services in Frederick, Md. Wendell Kerr is the owner of the company and a good friend. American Specialties work ethic is hard working, they are fast, there work is beautiful and the best you can get anywhere. If you need insulation that is a cut above the rest you need to give your next project to American Specialties and see for yourself. Wendell will always complete early and the job will look Great every time! Charlie Smith Dave's Mechanical Services, LLC. Frederick, Maryland, 21701
