Unit or building? Find the restriction
| Test | Result | Points to |
|---|---|---|
| Run the dryer with the lint screen clean and feel airflow at the duct connection behind it | Strong airflow at the dryer outlet | The restriction is downstream — duct or shared exhaust |
| Same test | Weak airflow at the dryer outlet itself | Lint inside the dryer cabinet or a failing blower — technician |
| Ask management when the exhaust risers were last cleaned | Not in recent memory | Request building exhaust service |
| Clothes damp, cabinet cool, airflow strong | — | Heating element, thermal fuse or gas ignition — technician |
Why shared exhaust behaves differently
A house dryer pushes air a short distance to an outside wall. In many towers, each unit's dryer feeds a vertical riser shared with the floors above and below; some buildings rely on a booster fan to keep that riser moving. When the riser loads with lint or the fan stops, every dryer on the stack slows down at once — so ask neighbours on your stack whether their drying times changed too.
Because lint is a leading factor in dryer fires, a restricted shared exhaust is a building safety issue, not just an inconvenience. Report it to management in writing.
What you can safely do
- Clean the lint screen every load and wash it if it's coated with dryer-sheet residue.
- Replace crushed or foil-type transition duct behind the dryer with semi-rigid metal duct, keeping it as short as the space allows.
- Don't push the dryer tight against the wall — leave room so the duct doesn't kink.
- Never open the building's riser or access panels; that's for the building's vendor.
Stop using the dryer if
Leave this to a professional
- You smell burning or see scorch marks.
- The cabinet is too hot to touch.
- It's a gas dryer and you smell gas — leave and call 911 from outside.
Booking the visit
Tell the provider it's a condo with shared exhaust, which floor you're on, whether a certificate of insurance is required, and when the service elevator is available. Stackable washer-dryer units in closets often need both machines pulled out — mention that too, because it affects time and price.

Common questions
My dryer got slow at the same time as my neighbour's. Is my dryer broken?
Probably not. A shared riser or a failed roof booster fan slows every dryer on the stack. Report it to building management before paying for a dryer repair.
Can I clean the shared dryer exhaust myself?
No. Risers and booster fans are building equipment; cleaning them requires access to other units or the roof. Clean your own lint screen and transition duct, and ask management to schedule the rest.
