Steven Ohl went above and beyond to get the bottom of our AC leak. He even helped us carry a spare wall unit up the steps and installed to keep us cool while we waited for parts. A ++

So happy we called Cassidy! We had an emergency late on a Sunday and Marcos got to us within an hour and 15 minutes from the time we called. He was really thorough, answered all our questions, and taught us a thing or too. Oh, and fixed the problem quickly! Really grateful he was our tech and appreciate his effort last night.
