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 Concord, CA
Dryer vent cleaning in Concord isn’t the same job it is in Oakland or Walnut Creek. The Diablo Valley traps heat and wildfire smoke against the hills, and the 1955-1975 ranch tracts along Clayton Road and Willow Pass Road were built with duct systems that are now 50+ years old and actively shedding debris. When we open a Concord dryer vent, we usually find 2-4 inches of packed lint and, often, a vent run that was rigged together from mismatched materials decades ago. Call (806) 606-6902 for a written price before we touch anything.
Why Concord Homes Are Different
Concord sits in an inland basin that holds wildfire smoke far longer than coastal Bay Area cities. During the 2018 Camp Fire, AQI here spiked well above San Francisco and stayed elevated for days, and homeowners running their HVAC to escape the heat pulled dense PM2.5 particulate directly into their duct systems. That is a recurring Concord problem, not a one-off, because the same valley geography blocks the marine layer and pushes summer temperatures to 95-105°F. Air conditioners run continuously for months, which means HVAC fans accumulate dust much faster than in Oakland or Walnut Creek.
The housing stock compounds it. Concord’s residential boom ran roughly 1955-1975, leaving a dense inventory of ranch-style tract homes with original sheet-metal supply trunks and early fiberglass duct board that is now degrading and shedding particulate into living spaces. Attic-routed duct runs sit in summer attic temperatures that routinely exceed 140°F, accelerating flex-duct liner breakdown and joint separation. Many of these systems have never been professionally cleaned, and our technicians regularly find collapsed or fully detached duct sections in Concord attic crawl spaces. In this city, the duct system itself is often the contamination source, not just surface dust.
Our Main Concord Services
Two services dominate our Concord call volume, both driven by the valley’s heat load and the age of the local duct systems.
Air Duct Cleaning in Concord
Whole-system air duct cleaning deals with the debris that accumulates inside supply and return duct runs over decades. In Concord, that debris is a mix of construction dust from the 1960s and 1970s, wildfire particulate pulled in during smoke events, and degraded duct board fibers that come from the system itself. We use negative-pressure extraction with professional-grade equipment from Brands like Rotobrush and Nikro, handling the full system from supply plenum to register. The full Concord breakdown, including pricing and local conditions, lives on the Air Duct Cleaning in Concord page.
HVAC Cleaning in Concord
HVAC cleaning goes deeper than the duct runs themselves: blower motor, evaporator coil, condensate pan, and the air handler cabinet. In Concord, those components run hard for months at a stretch, and the same particulate that settles in the ducts cakes onto the coil and blower wheel. A fouled coil here is a direct efficiency hit during the hottest months, not a cosmetic issue. The detailed Concord page, including cost ranges and what we document on the job, is at HVAC Cleaning in Concord.

BeforeAfterDryer Vent Cleaning in Concord
Dryer vent cleaning in Concord is a fire-safety job first, an efficiency job second. The combination of a long dryer vent run, a heated attic, and decades of deferred maintenance means lint builds up faster and packs tighter in Concord ranch homes than it does in coastal cities with shorter, cooler vent paths. The harshest part is the geometry: many vents on Clayton Road and Willow Pass Road tracts run 15-20 feet horizontally through a hot attic before they turn up through the roof. That length and heat cycles bake lint into a hard, fibrous plug that a standard homeowner cannot remove from the outside. We clean the full run, photograph it before and after, and include the photos in your job record. Read more about the service on our Dryer Vent Cleaning hub page.
Dryer Vent Inspection
Signs you need it
Clothes take two or more cycles to dry, or the dryer exterior feels unusually hot while the laundry room still smells damp.
What it costs in Concord
In Concord, a standalone dryer vent inspection with camera verification runs $95-$220 depending on roof access and vent run length.
How we do it
We feed a camera through the full vent run from the dryer connection to the exterior termination, then show you the before footage before any cleaning begins.
Lint Removal
Signs you need it
The dryer’s lint trap is clean but the unit still overheats, or you see lint blowing out the exterior vent cap or smell a burning scent during cycles.
What it costs in Concord
Full lint removal from the dryer connection to the exterior vent in Concord runs $130-$240, our most common dryer vent job.
How we do it
Trained technicians use professional-grade negative-pressure extraction tools and rotating brushes, then photograph the interior of the vent run to document what was removed.
Vent Rerouting
Signs you need it
The existing vent run has too many elbows, flex duct in a heated attic, or a termination that dumps into a soffit vent instead of outside.
What it costs in Concord
Rerouting a dryer vent in a Concord attic to a roof or wall termination with rigid metal duct typically runs $280-$700, with the spread driven by run length and roof slope.
How we do it
We replace flex and shortcut-prone runs with rigid metal duct, minimize elbows, and seal every joint with mastic so vented air moves in one direction.
Bird Guard Installation
Signs you need it
You hear scratching at the exterior vent cap, find nesting material blocking airflow, or notice lint and debris around the roof termination.
What it costs in Concord
Adding a bird guard to an existing exterior vent termination in Concord runs $90-$180, with the final number set by roof access and cap type.
How we do it
We remove the old termination, clean the final few feet of the vent run, and install a hooded guard that blocks birds and rodents while allowing full airflow.
What Dryer Vent Cleaning Costs in Concord
| Item | Typical range in Concord |
|---|---|
| Dryer vent inspection (camera) | $95 - $220 |
| Full lint removal (full run) | $130 - $240 |
| Vent rerouting with rigid metal | $280 - $700 |
How often should a dryer vent be cleaned in Concord?
Every year if you run the dryer daily in a home built before 1980. Concord’s attic heat bakes lint into compacted plugs much faster than in cooler coastal cities, so an annual camera check catches buildup before it becomes a fire hazard. Call (806) 606-6902 for a written quote.
Why does my Concord dryer vent clog so much faster than my last house?
Three local factors combine: hot attic runs that bake lint hard, longer horizontal vent paths in ranch-style tract homes, and decades of accumulated residue that makes new lint stick to the walls. A vent that is routed through a 140°F attic is not the same job as one that exits directly through an exterior wall.
Duct Repair & Sealing in Concord
Duct repair and sealing in Concord is frequently the prerequisite to any meaningful air duct cleaning. The same 140°F attic temperatures that bake lint into dryer vents also break down the adhesives and liners in 50-year-old duct systems along Clayton Road and Willow Pass Road. We regularly open a supply trunk in a Concord attic and find a joint that has pulled fully apart. Cleaning a system like that without sealing it first just stirs dust into the attic insulation and sends conditioned air into the roof cavity. The full service picture is on our Duct Repair & Sealing hub page.
Duct Sealing
Signs you need it
Rooms at the far end of the house run 5-10°F warmer than the rest, or your summer electric bill climbs even though the AC unit itself was recently serviced.
What it costs in Concord
Sealing accessible duct joints and seams in a standard Concord ranch runs $450-$1,200, driven by how much of the system is reachable from the attic.
How we do it
We seal every accessible joint and seam with mastic sealant, not foil tape, because mastic holds under Concord’s extreme attic temperature swings.
Flex Duct Repair
Signs you need it
You see crushed, torn, or disconnected flex duct in the attic, or one room stays dusty no matter how often the filter is changed.
What it costs in Concord
Replacing a collapsed or torn flex duct run in a Concord attic runs $220-$480 per run, depending on diameter and run length.
How we do it
We remove the failed section, install a correctly sized flex duct run, and seal both ends with mastic, then photograph the completed connection.
Duct Insulation
Signs you need it
The air coming from the registers feels warm in summer even when the AC is running, or visible condensation forms on the outside of the duct in the attic.
What it costs in Concord
Insulating exposed attic duct runs in a Concord home with R-6 or R-8 wrap runs $350-$900, set by the total linear footage and attic accessibility.
How we do it
We wrap exposed supply runs with R-6 or R-8 insulation, secure it with mechanical fasteners, and seal all seams so attic heat cannot contact the duct surface.
What Duct Repair & Sealing Costs in Concord
| Item | Typical range in Concord |
|---|---|
| Duct sealing (accessible joints) | $450 - $1,200 |
| Flex duct replacement (per run) | $220 - $480 |
| Duct insulation wrap (attic runs) | $350 - $900 |
Can I just clean my ducts instead of repairing them?
Not if the ducts are collapsed, detached, or leaking into the attic. In many Concord tract homes built between 1955 and 1975, cleaning first just pulls attic insulation and dust into the system through open seams. We inspect with a camera before recommending either job. Call (806) 606-6902 for a written assessment.
Does sealing my ducts actually lower cooling costs in Concord?
Yes, and more here than in coastal cities. When summer attic temps exceed 140°F, conditioned air leaking into that space is wasted money immediately. Sealing accessible joints cuts the loss and keeps the air you paid to cool inside the conditioned envelope.
Air Quality & Sanitizing in Concord
Air quality and sanitizing in Concord is about removing what the valley holds in. Wildfire smoke particle infiltration from events like the 2018 Camp Fire and the agricultural dust that blows in through the Carquinez Strait corridor both settle inside duct systems and get recirculated for months afterward. The 50-plus-year-old fiberglass duct board in many Concord ranch homes adds a third layer: degrading board that sheds particulate into the air stream on its own. We treat the source, not just the symptom. The full service breakdown is on our Air Quality & Sanitizing hub page.
Mold Treatment
Signs you need it
You see visible mold growth on duct surfaces or registers, or a persistent musty smell that gets stronger when the blower runs.
What it costs in Concord
Mold treatment in a Concord duct system with EPA-registered antimicrobials runs $450-$1,200, set by total duct run length and the extent of visible growth.
How we do it
We apply an EPA-registered antimicrobial to affected surfaces after source removal, then photograph the treated areas and include the record in your job file.
Odor Removal
Signs you need it
A stale, smoky, or pet odor persists even after the carpets have been cleaned and windows have been open for days.
What it costs in Concord
Whole-system odor removal in a Concord home runs $300-$650 and combines filtration, surface treatment, and air exchange based on what we find.
How we do it
We identify the odor source with a visual and camera inspection first, then treat with professional-grade air scrubbers and surface sanitizing, documenting each step.
UV Light Installation
Signs you need it
Recurring mold or bacterial growth on the evaporator coil, or a musty smell that returns within months of coil cleaning.
What it costs in Concord
Installing a UV-C light at the evaporator coil in a Concord HVAC system runs $650-$1,400, the spread driven by equipment brand and install complexity.
How we do it
We mount a UV-C light in direct line of sight of the coil and drain pan, wire it to the system, and test output before we leave.
Air Purifier Install
Signs you need it
Household members have persistent allergy symptoms indoors, or smoke events leave the home feeling stale for weeks afterward.
What it costs in Concord
Installing a whole-home air purifier in a Concord HVAC system runs $900-$1,800, depending on the unit selected and the existing system configuration.
How we do it
We install the purifier in the supply or return plenum, seal all connections, and verify airflow and electrical supply match the manufacturer specifications.
What Air Quality & Sanitizing Costs in Concord
| Item | Typical range in Concord |
|---|---|
| Mold treatment (whole system) | $450 - $1,200 |
| Odor removal (whole system) | $300 - $650 |
| UV light installation | $650 - $1,400 |
Will a UV light kill mold already growing in my Concord ducts?
No. UV light prevents growth on surfaces it can reach; it does not remove existing mold from the inside of a duct run. In Concord, where attic humidity and heat create the conditions mold thrives in, the treatment order is source removal first, then UV for prevention. Call (806) 606-6902 for a written plan.
Do I need air quality treatment if I already clean my ducts?
Sometimes, yes. Cleaning removes debris but does not address bacterial film or mold spores that have penetrated porous duct board surfaces. Concord’s wildfire smoke events leave a residue that attaches to surfaces, and sanitizing breaks that bond when cleaning alone cannot.

FAQs About Air Duct Cleaning in Concord
Smoke itself does not damage metal ducts, but the PM2.5 particulate it carries settles into fiberglass duct board and porous surfaces and stays there. In Concord specifically, repeated smoke events layer that particulate until cleaning is needed. The damage comes from the compressed debris accumulation inside aging duct runs, not the smoke alone.
Most cleaning and sealing work in Concord does not require a permit because it does not alter the system design or structure. If your repair involves replacing flex duct runs or structural changes to the plenum, Contra Costa County may require a permit. We check the scope and advise you in writing before any work begins.
In a standard Concord ranch-style home built between 1955 and 1975, a full air duct cleaning with photo documentation takes about 4-6 hours. Larger or multi-story homes with difficult attic access run longer. After the work, you receive the full photo record of every duct run, inside and out.
