Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning in San Ramon, CA
Dryer vent cleaning in San Ramon runs $89 to $189 for a standard single-story run, and most Dougherty Valley homes with second-floor laundry rooms land at the upper end because the vent path is 20 to 35 feet long. We photograph every vent run before and after so you can see exactly what came out. Call (806) 606-6902 and we’ll give you a written price before any work starts.
Why San Ramon Homes Are Different
San Ramon’s Dougherty Valley and Gale Ranch communities were built almost entirely between 2000 and 2015, which means most homes sit on original multi-zone HVAC systems that have never been professionally cleaned and still carry construction-era drywall and insulation dust inside the duct runs. These are large systems: 2,500 to 4,500 square feet with long flex-duct runs, multiple returns, and zone dampers that add complexity to every cleaning job. The city’s inland valley position pulls grassland pollen from the Diablo Range foothills and wildfire smoke from Northern California fires directly into running AC systems from May through October, and the Diablo wind pattern periodically spikes fine particulate levels across the valley. In our experience, a Dougherty Valley home that runs AC hard all summer accumulates duct debris at roughly twice the rate of a comparable coastal Bay Area home. The flex duct installed during the 2000s build-out was also rarely pressure-tested at seams, which means attic insulation fibers and dust have been actively pulled into supply air for a decade or more in many of these houses.
Our Main San Ramon Services
San Ramon homeowners call us most about two things: the full air duct cleaning that a 20-year-old Dougherty Valley system needs, and the deeper HVAC cleaning that gets at coils, blowers, and plenums when airflow has clearly dropped.
Air Duct Cleaning in San Ramon
Our Air Duct Cleaning in San Ramon covers every supply and return run in the house using negative-pressure extraction: a large vacuum unit attaches to the main trunk line while agitation tools knock debris loose from the duct walls. On a typical 3,000-square-foot Dougherty Valley home, we photograph the inside of every run before work begins, and the before photos usually show a gray film of construction dust and insulation fibers that has been there since the house was built.
HVAC Cleaning in San Ramon
Our HVAC Cleaning in San Ramon goes beyond the ducts to the evaporator coil, blower wheel, drain pan, and plenum, where San Ramon’s hot summer runtime leaves a baked-on layer of dust that standard duct cleaning never touches. We pull the coil panel, document what we find, and clean the full airflow path so the system stops recirculating what it has been pulling in from the Diablo foothills for the past decade.

BeforeAfterDryer Vent Cleaning in San Ramon
Dryer vent cleaning in San Ramon addresses a problem that is worse here than in most Bay Area cities: second-floor laundry rooms in Dougherty Valley homes push dryer exhaust through 20 to 35 feet of vertical or horizontal venting, and that long path accumulates lint faster than the short first-floor vents common in older housing. Hot, dry summers bake that lint into a compacted layer that cuts airflow and forces the dryer to run longer cycles. We clean, photograph, and document every vent run as part of a standard Dryer Vent Cleaning visit, and you get a written price before we open the first panel.
Vent Cleaning
Signs you need it
Clothes take two or more cycles to dry, the dryer feels hot to the touch on the outside, or you notice a burning smell when it runs.
What it costs in San Ramon
Vent cleaning runs $89 to $189 depending on vent length, access, and whether the outlet is at ground level or on a second-story wall or roof.
How we do it
We run a rotary brush and HEPA vacuum through the full vent path from the dryer connection to the exterior termination, then photograph the result.
Lint Removal
Signs you need it
Lint builds up around the exterior vent flap, or the flap does not open fully when the dryer runs because packed lint is blocking it.
What it costs in San Ramon
Lint removal falls between $89 and $189, and we include it as part of every vent cleaning rather than selling it as a separate add-on.
How we do it
We remove the exterior hood, pull the accumulated lint out by hand where it is compacted, then pass the rotary brush through to clear the remaining debris.
Vent Rerouting
Signs you need it
The current vent run uses vinyl or foil flex duct that is sagging, crushed, or not rated for dryer exhaust, which is a fire hazard under California building code.
What it costs in San Ramon
Vent rerouting costs $150 to $400 depending on whether we are replacing a short section or running new rigid metal duct through walls or a chase.
How we do it
We map the existing path, remove the substandard material, and install rigid metal duct with sealed joints from dryer to exterior termination.
Bird Guard Installation
Signs you need it
Birds are nesting inside the exterior vent hood, or you hear scratching and chirping near the laundry room wall when the dryer is off.
What it costs in San Ramon
Bird guard installation costs $45 to $120 per vent, including the guard, mounting hardware, and cleanup of any nesting material we find.
How we do it
We remove any nesting material, clean the vent, and mount a stainless steel guard over the exterior termination cap so birds cannot re-enter.
What Dryer Vent Cleaning Costs in San Ramon
| Item | Typical range in San Ramon |
|---|---|
| Vent cleaning (single vent) | $89 - $189 |
| Lint removal (included with cleaning) | $89 - $189 |
| Vent rerouting | $150 - $400 |
How often should dryer vents be cleaned in San Ramon?
Every 12 to 18 months for a typical Dougherty Valley home with a second-floor laundry. Longer vent runs and daily dryer use push that toward the 12-month end. We give you a written recommendation after each cleaning based on what we actually find.
Why does my San Ramon dryer vent clog faster than my old house’s did?
Long vertical runs on newer homes trap lint at every bend, and San Ramon’s dry summers bake that lint into a hard layer inside the vent wall. Shorter first-floor vents in older housing stock simply have fewer places for debris to accumulate. Call (806) 606-6902 for a written quote.
Duct Repair & Sealing in San Ramon
Duct repair and sealing in San Ramon deals with a specific failure pattern we see constantly in Dougherty Valley homes: the original flex duct installed during the 2000s build-out was never pressure-tested at seams, so conditioned air has been leaking into attics and crawlspaces since the day the house was finished. That means rooms that never quite heat or cool properly, higher PG&E bills, and registers that show gray staining from attic insulation fibers being pulled into the supply air. Our Duct Repair & Sealing work finds the leaks with a pressure test, shows you the evidence, and seals or replaces the failed sections with a written price before any work starts.
Duct Sealing
Signs you need it
Some rooms are always warmer or cooler than the rest of the house, or your energy bills stay high even after you replace the HVAC filter.
What it costs in San Ramon
Duct sealing runs $200 to $500 per zone or access point, depending on how many seams and connections need attention.
How we do it
We pressure-test the duct system to locate leaks, then apply mastic sealant or aerosol sealant to every failing seam and joint.
Flex Duct Repair
Signs you need it
The flex duct in the attic has visible kinks, tears, or compression from being walked on, or the gray staining around registers tells us insulation fibers are getting pulled through.
What it costs in San Ramon
Flex duct repair costs $150 to $350 per section, depending on the length of damaged run and whether it requires removal or patching.
How we do it
We remove the damaged section, inspect the surrounding run for additional failures, and install new flex duct with properly sealed connections at both ends.
Duct Insulation
Signs you need it
Attic ducts are sweating in summer, or the air coming out of the registers feels warm on hot afternoons because the duct is losing temperature through uninsulated walls.
What it costs in San Ramon
Duct insulation runs $150 to $400 per section, with the final price set by how much of the run needs to be wrapped or replaced.
How we do it
We wrap exposed ductwork with R-8 insulation, seal the vapor barrier at every seam, and photograph the finished work so you can see the coverage.
What Duct Repair & Sealing Costs in San Ramon
| Item | Typical range in San Ramon |
|---|---|
| Duct sealing (per zone/access point) | $200 - $500 |
| Flex duct repair (per section) | $150 - $350 |
| Duct insulation (per section) | $150 - $400 |
How do I know if my San Ramon ducts are leaking?
Rooms that never reach the thermostat setting, visible gray staining around registers, and energy bills that stay high despite a clean system are the three most common signs. We run a pressure test and show you the measured leak rate before recommending any work.
Is duct sealing worth the cost in San Ramon?
For most Dougherty Valley homes, yes. Original flex duct from the 2000s was rarely pressure-tested, and conditioned air leaking into a hot attic is money leaving the house every cooling cycle. Sealing typically pays for itself in lower cooling bills within a few seasons. Call (806) 606-6902 for a written estimate.
Air Quality & Sanitizing in San Ramon
Air quality and sanitizing in San Ramon handles what accumulates after years of wildfire smoke, Diablo wind particulates, and grassland pollen being pulled through a system that has never been cleaned. The result is ductwork that tests positive for mold, bacteria, or odor compounds, and indoor air that is measurably worse than the air outside even when the windows are closed. Our Air Quality & Sanitizing service treats the full airflow path with hospital-grade products from Abatement Technologies and installs Aprilaire or Honeywell filtration where a homeowner wants ongoing protection rather than a one-time clean.
Mold Treatment
Signs you need it
Musty smells come from the registers when the system runs, or you find visible mold growth on the inside of the plenum or around the coil.
What it costs in San Ramon
Mold treatment costs $250 to $600 depending on the number of duct runs affected and whether the coil and drain pan need treatment too.
How we do it
We photograph the affected areas, clean the visible growth mechanically, then apply an EPA-registered antimicrobial to the full duct interior using a fogger.
Odor Removal
Signs you need it
The system pushes out a stale or smoky smell every time the blower starts, even after you have changed the filter and cleaned the registers.
What it costs in San Ramon
Odor removal runs $150 to $350, and we combine it with a duct cleaning whenever smoke or cooking odors have bonded to the duct lining.
How we do it
We run an activated carbon filtration pass through the system, then treat the duct surfaces with an odor-neutralizing product that does not just mask the smell.
UV Light Installation
Signs you need it
The evaporator coil shows recurring mold or bacteria growth, or someone in the house has allergies that get worse when the AC runs.
What it costs in San Ramon
UV light installation costs $350 to $700 per unit, including the lamp, mounting hardware, and wiring to the blower circuit.
How we do it
We mount a UV-C lamp above the evaporator coil inside the plenum, wire it to run whenever the blower runs, and verify the wavelength with a meter.
What Air Quality & Sanitizing Costs in San Ramon
| Item | Typical range in San Ramon |
|---|---|
| Mold treatment | $250 - $600 |
| Odor removal | $150 - $350 |
| UV light installation | $350 - $700 |
Does sanitizing actually work, or is it just a spray?
It works when the product is applied correctly and the debris is removed first. We clean mechanically, then fog the duct interior with an EPA-registered antimicrobial, and we document the treatment with before-and-after photos of every run.
Will sanitizing get rid of wildfire smoke smell in my San Ramon ducts?
Yes, but only if paired with a full duct cleaning. The smoke odor binds to the dust and debris inside the ductwork, so the debris has to come out before any odor-neutralizing product can work. Call (806) 606-6902 for a written price.

No. Duct and dryer vent cleaning are interior mechanical maintenance, and no San Ramon HOA requires approval for work that does not alter the exterior of the home. The only exception is vent rerouting that changes the exterior termination point, which may need an architectural review.
Yes. Every job gets a Documented Photo Record of every duct run, photographed inside the run before work and after, delivered as part of the standard job record. You can see exactly what was inside your ducts and what they look like when we finish.
