Very professional & cleaned areas when work was complete. I would highly recommend their services. Also added dryer duct cleaning & micro bacterial spray in ducts. Price was very reasonable. Technicians will return to spray a sealant into my ducts to seal any small gaps. My ducts are in a crawl space & they had never been cleaned in my 18 yrs in the house. I really never gave duct cleaning a thought. I happened to get a new HVAC system & wanted the ducts cleaned. Win win for me.
