Apartment and condo laundry rooms, care homes, institutions, laundromats and hotels. Machines that run all day, into ducting that is longer and more complicated than anything in a house — and where the consequences of a blockage are not one family’s problem.
A commercial dryer vent is not a residential one that happens to be bigger. Three factors compound, and each one makes the others worse.
A household dryer runs perhaps five or six loads a week. A shared laundry room in a forty-suite building can run from six in the morning until eleven at night, every day, all year. A care home or a laundromat runs harder still.
Lint accumulation scales with hours of operation, not with the calendar. That is why a commercial system on an annual schedule is often in worse condition after twelve months than a household one after five years.
Residential runs are usually short and reasonably direct. Commercial and multi-unit runs are neither. In-suite dryers frequently vent into a shared vertical riser serving the whole stack. Laundry rooms in basements or interior cores have long horizontal runs to reach an exterior wall. Long runs often need inline booster fans to maintain airflow.
Every one of those — the riser, the long horizontal, the booster fan housing — is somewhere lint settles. And all of them are past the point where anyone cleaning from the appliance end will reach.
This is the part that changes the conversation. In a house, a neglected dryer vent is a homeowner’s own risk. In a building it is a shared structure, other people’s homes, and a maintenance record that a property manager, a condo board or an insurer may eventually ask to see.
Lint is highly combustible, and it sits inside a duct carrying heated air. That is the whole mechanism. It is not complicated, and it is entirely preventable with a schedule.
A blocked or partly blocked exterior termination. Screens that were never meant to be there, damper flaps seized shut with packed lint, or — every spring — a bird nest. The dryers still run, tenants complain that clothes take two or three cycles, and nobody connects that to the vent until someone looks outside.
Every metre of the run, from the back of each dryer through to the exterior hood. Cleaning one end and calling it done is the most common shortcut in this trade.
Vertical risers serving a whole stack of suites, and any shared horizontal collector. These accumulate from every unit feeding them and are almost never accessed.
Cleaned and checked. A booster fan that has failed or clogged turns a long run into a blocked one, and nothing in the laundry room tells you it has happened.
Hoods, dampers and screens checked and cleared. Including bird nests, which around here is a routine spring finding rather than an unusual one.
Number of machines, run configuration, booster fans, termination access. You get a fixed number in writing, with insurance and WCB certificates if you need them.
Shared laundries at low-use times, worked through in sequence so the room is not out of service all day. In-suite work planned around whatever notice period your building requires.
Each machine, each branch, the shared riser, booster fans and the exterior termination. Debris is drawn out rather than pushed further along the duct.
Before-and-after images and written notes on anything that needs attention — crushed duct, disconnected runs, failed boosters, damaged hoods. Something you can put on file.
That is a restricted vent, and it is measurable. We’ll show you what’s in there.
