Our dryer technician last week recommended duct cleaning so we turned to Orsan for a dryer vent clean and a duct clean for the entire house. Both technicians arrived ahead of time and were so friendly and helpful explaining the process. I decided to add on a new furnace reusable filter at the end which did bring the cost up by 150 however with the much improved air flow it only made sense. The dryer vent was literally jammed with 6 ft of bird nest and assorted materials. Well worth the cost considering this is a service I would do every 3 to 5 years. No worry now about dryer vent fires or low volume air flow. Very very happy!
