Dryer Vent Cleaning San Francisco

If your clothes need two cycles to dry, the vent is usually why. We clear the full duct run, check how it was installed, and tell you what we find. Homes, condos and townhouses across San Francisco and the Bay Area.

Two Cycles to Dry a Load? That's the Vent.

A dryer works by pushing hot, wet air out of the house. When lint narrows the duct, that air has nowhere to go, so the moisture stays in the drum and the clothes come out damp.

‍

Most people respond by running another cycle. That doubles the running cost, and it puts the dryer under exactly the load it was never designed for: more heat, less airflow, for twice as long.

‍

The lint trap only catches part of what comes off your clothes. The rest goes into the duct, and it builds up somewhere you can't see or reach.

‍

Signs Your Vent Needs Clearing

Clothes still damp after a full cycle, or needing a second one. The laundry room gets noticeably hot while the dryer runs, the outside vent flap doesn't open, or barely moves, when the dryer is on a burning or hot-lint smell during a cycle Lint appearing around the back of the dryer or on the floor behind it, the dryer shutting itself off mid-cycle. More than a year since it was last done

‍

The dryer shutting off on its own is the one to act on quickly. Dryers are built to cut out when they overheat, and a blocked vent is the usual reason it happens.

Why homeowners choose mother nature's cleaning

We Check the Whole Run

Not just the six feet you can reach from behind the dryer. Blockages are usually further along, at a bend or at the outside vent.

We Measure Airflow

Before and after. It's the only way either of us knows whether the clean actually achieved anything.

We Tell You What's Wrong

Foil duct, a screened outside cover, screws through the duct wall. These are common, and they undo a clean within months.

Honest Assessment

If your vent doesn't need doing yet, we'll say so and tell you when to book instead.

What we check besides the lint

A vacuum down the duct is the easy part. Most vents that clog again quickly do so because of how they were built, not because nobody cleaned them.

Duct material

Code calls for rigid metal duct with a smooth interior. The ribbed foil hose sold in hardware stores catches lint in every ridge and crushes flat behind the dryer. If yours is foil, we'll show you, and we can replace that section between the dryer and the wall.

Length and bends

The California Mechanical Code limits a dryer duct to 14 feet, including two 90-degree elbows, with 2 feet off for every elbow after that. Plenty of San Francisco homes with the laundry away from an outside wall are over it. We'll tell you if yours is.

Screws through the duct

Joints aren't supposed to be fastened with screws that project into the duct, because every protruding point collects lint until the duct closes up around it. It's one of the most common installation faults we find.

The outside termination

The exterior cover needs a working damper and no screen or mesh. Screens catch lint and birds nest behind broken flaps. A blocked termination undoes everything done inside the house.

Where it ends up

A dryer duct has to terminate outside. Venting into a garage, crawlspace or attic puts moisture, lint and, with a gas dryer, combustion gases into the building. We still find it.

What We Do and What We Don't

So nobody wastes a phone call.

If You Have a Gas Dryer

Worth knowing, because it isn't widely understood.

‍

A gas dryer burns fuel, so its exhaust contains carbon monoxide along with the hot air and lint. As long as the duct is sealed and clear, all of that goes outside. If the duct is blocked, disconnected, or leaking at a joint, some of it can end up in the house instead.

‍

This is why the duct behind a gas dryer matters more than people assume, and why a CO alarm near the laundry area is worth having whether or not you ever call us.

‍

One thing to know before you book: we don't disconnect gas lines. If your dryer can't be reached without that, you'll need a plumber or appliance technician to handle that part first.
