Owen's crew spent six hours on our three systems. The camera-scope video was shocking — our supply trunks looked like a different duct. My son's asthma flares dropped noticeably in the first two weeks.

Third duct cleaning company we've used in 15 years. The first two vacuumed three vents and sent a bill. Long Island Air Duct actually hooked a negative-air machine to the plenum, brushed every line, and handed us a printed report. Worth every dollar.

Booked them for a dryer vent cleaning after a fire-risk article scared me. Theo pulled three cubic feet of lint out of the line. Dryer runs half as long now. They also showed me the camera footage on a tablet.

Had mold in the return plenum after a finished-basement water issue. Owen ran an inspection with swab samples, sent them to an independent lab, and coordinated remediation. Clean and certified in four days.

Brand new construction, builder did nothing about the sawdust in the ducts. Long Island Air Duct cleaned every run before we moved in. First week in the house my wife's allergies were silent.

Medical office, 6,200 sq ft. Quoted three HVAC companies. Owen's team was mid-price but the only one that sent a written NADCA-compliant scope. Came in on a Saturday. Pros.

I'm the kind of customer who reads reviews twice. Long Island Air Duct was not the cheapest. They were the ones who explained what NADCA actually means, showed up when they said, and did not try to sell me an air scrubber I didn't need.

Cape built in 1962, original ducts. I expected a nightmare. Crew wrapped the floors, protected the furniture, did two systems in a long day, and the house smells different in a good way.

Dog hair, old carpet fibers, who knows what else. Owen pulled a bag full of debris from our supply lines and the house honestly feels different. Our IAQ monitor dropped about 60% for PM2.5.
