Had Zach Vac clean our ducts and dryer vent today. The guys were very friendly and respectful of our home. They wore booties over their shoes and cleaned everything up. They took precautions to protect our furniture from being damaged with their large hoses. They were very thorough. They took pictures of the inside of our ducts when they were done to show us how clean they were. Then they used disinfectant in the ducts when they were finished. We are very happy with the job they did.
