I have been using Service Specialties Inc for over 3 years now. They are one of the best Heating and AC companies I have ever used. I have lived in the Northern Virginia area all my life and this is the best Heating and AC companies I have ever had. Clint Boyd the technician that has come to my house multiple times for my service contract and for warranty work at my fathers house is outstanding. He has to be one of the most knowledgeable technicians I have ever met. He is always on time if not early and is efficient and explains everything in detail so you can understand it. His quality of work is outstanding. Any company would be lucky to have him as an employee.
