Air Duct Cleaning in San Jose - One Flat Price, Before-and-After Photos

Air Duct Cleaning in San Jose, CA

Dryer vent cleaning in San Jose carries a weight that most cities never feel. The valley’s bowl-shaped geography traps wildfire smoke, pollen, and fine dust for days at a time, and the region’s 1960s through 1980s ranch homes were built with long, low-slung vent runs that collect every bit of it. CleanRun Air Duct Cleaning handles the full picture: dryer vent cleaning, duct repair and sealing, and air quality and sanitizing, all with written pricing before any work starts. Call (806) 606-6902 and we’ll put the number in your hand before a single panel comes off.

Why San Jose Homes Are Different

San Jose sits in a bowl. The Santa Cruz Mountains rise to the west and the Diablo Range to the east, and when fires burn in those hills, the valley’s temperature inversions hold the smoke at ground level and push it into residential HVAC systems at concentrations you simply won’t find in a breezy coastal city like San Francisco. The 2020 SCU Lightning Complex and CZU fires were a stark demonstration: for weeks, the indoor air quality of San Jose homes was only as good as the filtration and ductwork that stood between the living room and the outside air.

Then there’s the housing stock. Dominant neighborhoods like Cambrian, Berryessa, Alum Rock, and East San Jose are full of single-story tract homes built between roughly 1960 and 1985. Most still run their original attic-mounted forced-air systems and flex ductwork. Attic temperatures in low-slope ranch roofs routinely exceed 130-140°F during San Jose summers, which degrades flex duct insulation and adhesive sealing compounds, causing ducts to sag, crack, or separate at joints. That means what starts as a simple cleaning job in Berryessa often reveals disconnected duct sections that have been silently pumping conditioned air into the attic for years. The work here is not cosmetic. It’s mechanical, and it’s measurable.

Our Main San Jose Services

Two services account for most of the calls we take from San Jose homeowners, and both have a dedicated page if you want to go deeper.

Air Duct Cleaning in San Jose

Full-system air duct cleaning in San Jose has to account for what the valley’s inversions deposit into residential ductwork: wildfire smoke residue, road dust, and the fine particulates that collect in long flex runs that were never designed for today’s air quality challenges. Our crews use negative-pressure extraction with professional-grade Rotobrush and Nikro equipment, and every duct run is photographed before and after as part of the standard job record. If you want the complete breakdown of pricing and process for whole-system cleaning, see Air Duct Cleaning in San Jose.

HVAC Cleaning in San Jose

HVAC cleaning in San Jose means more than the ducts. It covers the blower assembly, evaporator coil, drain pan, and the returns that carry air back through your system, all of which suffer in this valley’s heat and particulate load. A clogged coil or a dirty blower wheel reduces airflow and forces a system to work harder all summer, which is a real expense in a city where summer cooling is not optional. For the full scope of what we clean and how it’s priced, see HVAC Cleaning in San Jose.

Dryer Vent Cleaning in San Jose

Dryer vent cleaning in San Jose is the service we recommend most urgently for homes in this valley. Long vent runs common in 1960s-1980s ranch houses in Cambrian, Berryessa, and Alum Rock collect lint fast, and when you add the fine particulate load that comes with valley inversions and wildfire season, those runs clog faster than any guidebook predicts. A blocked dryer vent is a genuine fire hazard, and the solution is documented cleaning with before-and-after photos, which is exactly what our Dryer Vent Cleaning service delivers.

Vent Cleaning

Signs you need it

Clothes are taking longer than 40 minutes to dry, the dryer exterior is hot to the touch, or you can smell a musty, burnt-lint odor in the laundry area.

What it costs in San Jose

Standard dryer vent cleaning in San Jose typically ranges from $95 to $165 for a single-story, roof-vented run.

How we do it

We run a rotating brush the full length of the vent from the dryer connection to the exterior termination, then vacuum the entire run with negative-pressure extraction and photograph both ends when finished.

Lint Removal

Signs you need it

Visible lint accumulation around the exterior vent flap, reduced airflow at the termination point, or a dryer that shuts off mid-cycle on high temperature.

What it costs in San Jose

Deep lint removal from a heavily clogged or multi-elbow vent run in San Jose typically runs $135 to $210 depending on run length and access.

How we do it

We dislodge compacted lint with professional Rotary brush equipment, then extract the debris with a HEPA-filtered vacuum and provide a photo record of the cleaned interior.

What Dryer Vent Cleaning Costs in San Jose

How often should dryer vents be cleaned in San Jose?

Every 12 months for households that run the dryer 2+ cycles per week, and every 6 months during wildfire-heavy years because smoke particulates collect in the lint and increase fire risk. Call (806) 606-6902 and we’ll schedule you on a sensible interval.

Will cleaning lower my utility bill in San Jose?

Yes, directly. A restricted vent forces the dryer to run longer, and PG&E rates in San Jose make that expensive. A clean vent shortens cycle times measurably. Call (806) 606-6902 for an estimate with a written price before work begins.

Duct Repair & Sealing in San Jose

Duct repair and sealing in San Jose is frequently the difference between a system that works and one that quietly wastes money. The valley’s attic heat accelerates flex duct degradation, and we regularly find disconnected or collapsed sections in homes that were simply booked for a basic cleaning. If you’re losing conditioned air into your attic or a particular room never holds temperature, the problem is often in the ductwork, and our Duct Repair & Sealing service is built for exactly that.

Flex Duct Repair

Signs you need it

Rooms at the far end of the house run noticeably warmer or cooler than the rest, or you see dust blowing from registers when the system starts.

What it costs in San Jose

Flex duct repair or replacement in San Jose typically ranges from $180 to $480 per section, depending on run length, diameter, and attic accessibility.

How we do it

We remove the damaged flex duct section, patch or replace the run with R-6 or R-8 rated material sized to your system, and secure every collar joint with mastic sealant before photographing the finished work.

Duct Sealing

Signs you need it

Rooms above the garage or at the end of long runs stay hot in summer and cold in winter, or you can see gaps and separation at duct joints in the attic.

What it costs in San Jose

Whole-system duct sealing in San Jose typically runs $350 to $750 for an average ranch home, with a written breakdown by section provided before work begins.

How we do it

We seal every accessible joint, collar, and connection with mastic sealant, then verify system static pressure and airflow before and after to document the improvement.

What Duct Repair & Sealing Costs in San Jose

Can you repair my ducts the same day you find the problem?

In most cases, yes. If we find a disconnected or damaged section during a cleaning or inspection, we can usually repair it that same visit with parts from the truck. Call (806) 606-6902 for a written price first.

Do I need a permit to repair ductwork in San Jose?

No permit is required for repair or sealing of existing ductwork, but San Jose building code requires repairs to match current energy standards for insulation and sealing. We work to those standards on every job. Call (806) 606-6902 for specifics on your home.

Air Quality & Sanitizing in San Jose

Air quality and sanitizing in San Jose is where the valley’s geography hits home most directly. When wildfire smoke lingers, particulates settle into the ductwork and the system recirculates that residue for months, leaving behind odors and respiratory irritants. San Jose’s older ranch homes often have 40-year-old duct interiors lined with dust and smoke char, which is exactly what Air Quality & Sanitizing addresses: treating the system, not just masking the smell.

Odor Removal

Signs you need it

A persistent musty or smoky smell when the system runs, even after the ducts have been cleaned, or after a kitchen fire or wildfire smoke event.

What it costs in San Jose

Whole-system odor removal and duct sanitizing in San Jose typically ranges from $180 to $340, depending on system size and the level of smoke saturation.

How we do it

We apply an EPA-registered antimicrobial and odor-neutralizing treatment to every accessible interior surface of the ductwork, then follow with a photo record of the treated runs.

UV Light Installation

Signs you need it

A history of mold or mildew on the evaporator coil or inside the plenum, or a household member has allergies that worsen when the HVAC system runs.

What it costs in San Jose

UV light installation in San Jose typically runs $320 to $600 per coil-mounted lamp system, including the lamp, installation, and verification of placement.

How we do it

We install a Honeywell or Guardsman UV-C lamp system directly at the evaporator coil, wired to run when the system runs, and verify lamp intensity with a radiometer before photographing the final placement.

What Air Quality & Sanitizing Costs in San Jose

Will sanitizing remove all wildfire smoke odor from my ducts?

In the majority of San Jose homes, yes. The treatment neutralizes smoke residue and microbial growth inside the ductwork, and we photograph the treated interior as part of the standard record. Call (806) 606-6902 for a written price based on your system size.

Is the treatment safe for kids and pets?

Yes. The products we use are EPA-registered for use in residential HVAC systems, and we follow the manufacturer’s dwell time exactly before the system is turned back on. Call (806) 606-6902 for the product name and safety data sheet.
