Definitive Air is the most honest, reliable AC company in the valley. They are reasonably priced, they never mislead you and they are the friendliest, nicest family I have ever met. This is a family run business, Mike does all of the work personally himself, and sometimes brings his son (or daughter) and his wife schedules the calls. She is so sweet. I trust this company to do all of my AC work and would refer them to anyone. Mike I such a great, honest guy. Love this company!
