I highly recommend this company for air conditioning duct cleaning. My first contact was with Joe, and he was amazing! He help me figure out how much I would be charged, and set up an appointment right away. My technician Judah was courteous, polite, and very efficient! I noticed my breathing improved 80% by the end of that first day. I woke up feeling and being able to breathe a whole lot better. Thank you air quality express houston for your commitment to service!
