A clogged dryer vent is more than a nuisance; it’s a fire risk. National data shows roughly 2,900 residential dryer fires in the U.S. each year, causing millions in property damage and avoidable injuries. In San Jose, many homes and townhomes vent dryers up through the roof or long runs with multiple elbows, which collect lint faster and strain your dryer. If your laundry is taking two cycles, the outside vent flap barely moves, or the laundry room feels unusually hot, it’s time to clean the vent. You’ll learn who actually does dryer vent cleaning near you in San Jose, what a good service includes, typical local pricing, and how to book confidently without getting upsold into something you don’t need. I’ll also share pro-level tips that save time and headaches, including HOA considerations, code basics, and the small details techs look for when airflow is poor.
Quick Answer
In San Jose, dryer vent cleaning is commonly performed by HVAC contractors, air duct cleaning firms, chimney sweep companies, and dedicated dryer vent specialists; some appliance repair shops also offer it. Expect standard pricing around 149–249 dollars for a single-story wall termination and 179–349 dollars for roof access or longer runs. When you call, ask if they clean the exterior cap, use rotary brushing with a high-powered vacuum, and verify airflow after service.
Why This Matters
Dryers work by moving heat and air. When lint chokes the vent, heat builds, drying times double, and parts wear faster. In San Jose, roof terminations and long runs found in townhomes and condos are especially prone to clogging. If a normal full load should dry in about 45–60 minutes but takes 90+, your vent is likely restricting airflow.
The impact is real. An electric dryer can use 1.5–5 kWh per cycle; at Bay Area rates, extra cycles add up to 100–200 dollars per year. Gas dryers waste fuel and can backdraft if ventilation is poor. Lint around a hot heating element is a fire hazard, and damaged ducts leak warm moist air into walls or attics, inviting mold and pests.
Consider a common scenario: A Willow Glen bungalow with a long, older flex duct starts tripping a dryer vent warning. Cleaning removes dense lint from two elbows and a roof cap, airflow improves, and drying time drops by 30–40 minutes. That’s less energy, less wear on the appliance, and a safer home.
Step-by-Step Guide
Step 1: Confirm you need service
Before booking, note symptoms. Clothes taking two cycles, a hot or humid laundry room, a slight burning lint smell, or lint visibly collecting around the exterior hood are red flags. Many modern dryers display a vent check warning when backpressure is high. If you step outside during a load and the damper barely opens or airflow feels weak, the vent likely needs cleaning. You might find dryer vent cleaning brush helpful.
- Time a normal load; over 75 minutes is a concern.
- Watch the exterior flap during operation; it should open fully.
- Check behind the dryer for a crushed or foil-style flex connector; those clog easily.
Step 2: Map your vent path and access
San Jose homes often vent up through the roof. Identify whether the termination is on a wall or roof, approximate run length, and how many elbows. This affects pricing and tools.
- Townhomes and condos often have 20–35 feet runs and roof jacks.
- Note if a ladder is needed or if HOA approvals are required.
- Gas dryer present? Keep the area ventilated and inform the tech.
Step 3: Choose the right provider
Call two or three local options: HVAC contractors, air duct cleaning firms, chimney sweeps, or dedicated dryer vent specialists. Ask specific questions to filter pros from general handymen.
- Do you use rotary brush rods with a high-powered vacuum, and do you clean the exterior cap?
- Will you replace the transition duct with UL 2158A listed semi-rigid or rigid if it’s damaged?
- Do you measure airflow or backpressure and provide photo documentation?
- Are you insured and, if installing or repairing duct, appropriately licensed for California?
Step 4: Prep for the appointment
Clear 3–4 feet around the dryer. Remove items from the top and nearby shelves to avoid dust. If the dryer sits in a tight closet, plan for safe movement. Provide parking and gate codes, and let the tech know about pets. You might find dryer vent cleaning kit helpful.
- Run the dryer on air fluff for 5 minutes before arrival; warm lint dislodges more easily.
- Have a trash bag handy for lint and debris at the termination cap.
- If roof access is required, confirm ladder access and any HOA roof rules.
Step 5: What a proper cleaning includes
Pros disconnect the transition duct, brush and vacuum the full run from one or both ends, and clean the exterior cap and damper. If screens are present at the termination (not allowed on dryer vents), they’ll remove them. They’ll replace crushed or non-listed flex with UL 2158A semi-rigid or rigid and secure with worm clamps, not tape alone.
- Look for brushing through every elbow; lint packs here.
- Exterior cap should open freely after cleaning.
- Airflow or backpressure should be checked; typical dryers move roughly 85–160 CFM when clear.
Step 6: Aftercare and scheduling
Test a normal load; drying time should drop noticeably. Set an annual reminder, or twice a year if you have long runs, roof terminations, or heavy laundry use. If airflow remains poor, discuss duct repair, rerouting, or a code-compliant booster fan placed and wired correctly. You might find dryer lint vacuum attachment helpful.
- Keep the lint screen cleaned every load.
- Avoid foil or plastic flex; they trap lint and are a fire hazard.
- Consider a lint alert device if your run is long or in a multi-family building.
Expert Insights
San Jose homes frequently route dryer vents vertically to the roof, adding elbows and length. Each 90-degree elbow costs airflow; manufacturers typically limit equivalent length to around 35 feet, which can be exceeded in townhomes. When airflow drops, lint accumulates faster and heat spikes, so annual cleaning is smart in these layouts.
Common misconceptions: blowing air from the dryer side clears everything, and foil flex is fine. In reality, lint packs hardest at elbows and the termination cap, which need mechanical brushing. Foil and plastic flex are prone to crushing and ignition; use UL 2158A semi-rigid or rigid metal only, secured with clamps.
Pro tips that save headaches: ask for photo proof at the termination cap and inside the duct, and request a quick airflow or backpressure check after service. If birds are a problem, install a proper dryer-rated cap with a damper, not a screen. For condos and HOAs, confirm the contractor’s insurance and roof safety plan, and schedule mid-week mornings when roof access is simplest. If your dryer still flags a vent error, check the internal blower wheel for lint and the transition path for kinks before assuming the main duct is the culprit.
Quick Checklist
- Note vent path, roof or wall termination, and approximate length
- Call 2–3 local providers and ask about rotary brushing and airflow testing

- Replace damaged or foil/plastic flex with UL 2158A semi-rigid or rigid
- Verify insurance and appropriate licensing for any duct repairs
- Clear 3–4 feet around the dryer and provide roof access if needed
- Request before/after airflow or backpressure readings
- Set an annual reminder; increase frequency for long runs or heavy use

Frequently Asked Questions
Who actually handles dryer vent cleaning in San Jose?
HVAC contractors, air duct cleaning firms, chimney sweep companies, and dedicated dryer vent specialists commonly offer it here. Appliance repair shops sometimes include vent cleaning as part of dryer service, especially when a vent error code appears or drying times are excessive.
How much does dryer vent cleaning cost locally?
Typical San Jose rates run 149–249 dollars for a straightforward, single-story wall termination. Roof access, long runs, bird nest removal, or multiple elbows can push it to 179–349 dollars. Duct repairs or transition replacements are usually add-ons (50–150 dollars), and full duct rerouting costs more.
How often should I get my dryer vent cleaned?
For most households, once a year works well. If you have a long vent run, a roof termination, a large family with frequent loads, or pets that shed (which adds lint and dander), consider every 6–9 months. If a load starts taking 75–90 minutes, don’t wait for your annual reminder.
Can I DIY dryer vent cleaning?
You can clean the lint screen every load and vacuum behind the dryer, and basic brush kits help for short, straight runs. Roof terminations, long ducts, and multiple elbows are tougher; professionals use rotary brush rods and high-powered vacuums to avoid compacting lint deeper. Improper DIY can damage the duct or push lint into the cap.
Is there a safety risk with a clogged vent?
Yes. Lint is highly combustible, and restricted airflow raises heat inside the dryer. National fire data estimates roughly 2,900 dryer fires annually. Gas dryers can also backdraft if ventilation is poor, increasing carbon monoxide risk. Cleaning reduces these hazards and lowers energy use.
What should a proper service include?
Expect full-run rotary brushing and vacuuming, exterior cap cleaning, transition duct inspection and replacement if needed, and an airflow or backpressure check. The tech should secure connections with worm clamps and provide photos. Screens at the termination should be removed, as they trap lint and aren’t allowed on dryer exhausts.
How long does the appointment take?
Most jobs take 45–90 minutes. Roof access, bird nest removal, very long runs, or tight laundry closets can add time. If you’ve had persistent vent warnings, allow a bit longer for inspection and testing after cleaning.
Conclusion
Finding dryer vent cleaning near you in San Jose is straightforward once you know who to call and what a solid service looks like. Start by noting your vent path and booking an insured pro who brushes the full run, cleans the exterior cap, and verifies airflow. After the visit, test a normal load, replace any weak transition duct, and set a reminder for your next cleaning. A clear vent means faster drying, lower energy bills, and a safer home—worth an hour on the calendar.
