What dryer vent cleaning should include (not just “the lint trap”)
A legitimate dryer vent cleaning service addresses the entire exhaust path:
Dryer connection area (as appropriate/safe)
Transition duct/connector condition
Full vent run to the exterior termination
Exterior hood/termination cleared and verified for airflow
Dryer vent maintenance is a fire-safety issue. UL recommends having the exhaust vent inspected annually and cleaned to reduce fire risk. NFPA research shows lint/dust/fiber are common first-ignited items in dryer fires.
Signs you may need dryer vent cleaning (common in Long Island homes)
Clothes taking longer to dry
Dryer feels hotter than normal / laundry room heat buildup
Burning smell or “hot lint” smell
Exterior flap/hood barely opens while running
You have a long run, multiple elbows, or a rooftop termination
They quote a low price, then claim your vent is “too clogged,” “too long,” or “on the roof,” and push a huge upcharge. (Sometimes the upsell is legitimate, sometimes it’s not. The key is a written scope and clear pricing before they start.)
They insist you must replace everything without showing you the issue (crushed line, improper material, severe restriction). If replacement is needed, you should be shown why and given options.
