"I was very impressed with the work done by Hawk Air Duct Cleaining. After a mold remediation, I wanted the ducts cleaned to make sure they were not harboring any spores or toxins from that incident. Hawk was professesional, communicated clearly, and did an excellent job. Their vacuum truck creates a negative pressure in the whole system and then they cleaned each duct individually. They even left the vent covers sparkling."
