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 Dimas, CA
Dryer vent cleaning in San Dimas runs $139-$189 for most single-story homes, and the reason it matters more here than in flatland cities is the Santa Ana wind pattern that pushes chaparral dust and wildfire ash directly into foothill laundry rooms. Homes in Via Verde and the 1960s-1980s ranch tracts around San Dimas Canyon carry original dryer duct runs that lint has been accumulating in for decades. Call (806) 606-6902 and we’ll give you a written price before a single panel comes off.
Why San Dimas Homes Are Different
San Dimas sits at the mouth of San Dimas Canyon, a funnel point where Santa Ana wind events drive chaparral dust, pollen, and ash from the Angeles National Forest straight into the city. The same geography that makes the foothills scenic also makes them a collection zone. Prevailing westerly winds push particulate pollution east across the San Gabriel Valley, and it piles up against the mountains right here, giving San Dimas some of the highest PM2.5 readings in Southern California. Ductwork in this city accumulates contaminants noticeably faster than systems in communities a few miles west.
The housing stock compounds the problem. A large share of San Dimas homes are 1960s-1980s ranch-style tract construction, including the Via Verde planned community. Their original flex and galvanized sheet-metal ductwork is now 40-50 years old, running through attics that exceed 150°F in summer. That kind of heat breaks down liner material and separates joints, letting attic dust and loose insulation fibers get drawn into the living-space air stream. Add in post-fire ash from ridgeline burns like the 2014 Colby Fire, and you have duct systems that fill with fine gray particulates standard 1-inch filters simply cannot catch.
Our Main San Dimas Services
San Dimas homeowners call us most often about two jobs: full air duct cleaning and HVAC system cleaning. Both address the same local condition differently, and each has its own San Dimas page with full pricing.
Air Duct Cleaning in San Dimas
Air duct cleaning here means removing what the Santa Ana winds and the terminal airshed deposit into your duct runs: fine dust, chaparral pollen, post-fire ash, and attic insulation fibers pulled through separated joints in aging flex duct. We photograph every run before and after, and the written price is set before work begins. For the full scope, pricing, and what to expect in San Dimas specifically, see the dedicated Air Duct Cleaning in San Dimas page.
HVAC Cleaning in San Dimas
HVAC cleaning targets the mechanical side: blower wheel, evaporator coil, plenum, and the registers that distribute conditioned air through your home. In San Dimas, where systems run continuously during Santa Ana events and wildfire smoke season, coils and blowers collect a film that reduces airflow and efficiency. The HVAC Cleaning in San Dimas page covers the full job, including photos we take of the coil before and after.

BeforeAfterDryer Vent Cleaning in San Dimas
Dryer vent cleaning in San Dimas costs $139-$189 for a standard single-story home with a roof or sidewall termination. The job matters here because the same Santa Ana winds that push ash through your window screens also press against exterior vent terminations, and the 1960s-1980s laundry rooms common in Via Verde and older ranch tracts often route dryer exhaust through long, multi-elbow runs that trap lint faster than shorter modern installs. You can read more about the full scope on our Dryer Vent Cleaning page, including what’s included in every visit.
Dryer Vent Inspection
Signs you need it
If your dryer takes longer than one cycle to dry a full load, or the laundry room gets noticeably humid while the dryer runs, the vent is telling you it’s restricted.
What it costs in San Dimas
A camera inspection runs $89-$129 in San Dimas, and the written quote includes photos of the vent interior.
How we do it
We run a camera through the full duct run, photograph every elbow and termination point, and show you the restriction in the photo record before recommending any work.
Lint Removal
Signs you need it
Visible lint around the exterior vent flap, or a dryer that shuts off mid-cycle on its thermal overload, means the accumulation is deep in the run.
What it costs in San Dimas
Full lint removal is included in the $139-$189 dryer vent cleaning price, plus an added fee of $30-$75 if the run requires roof access.
How we do it
We use negative-pressure extraction with a rotary brush sized to your duct diameter, pulling the debris backward out of the run instead of pushing it through the wall.
Vent Rerouting
Signs you need it
A vent run longer than 25 feet or with more than three elbows traps lint before it ever reaches the exterior termination.
What it costs in San Dimas
Vent rerouting starts at $250 per run, with the final number dependent on the new termination path through wall or roof.
How we do it
We map the shortest code-compliant route, replace rigid or semi-rigid duct with the right material for San Dimas’s attic heat, and document the full new run with photos.
Bird Guard Installation
Signs you need it
Nesting material, droppings, or chirping sounds near the exterior vent hood indicate birds have made the warm vent a home.
What it costs in San Dimas
A bird guard installation runs $40-$75, plus debris removal if nesting material is obstructing the run.
How we do it
We remove any nesting material carefully, clean the termination, and install a screened guard that allows airflow while blocking re-entry.
What Dryer Vent Cleaning Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Dryer vent cleaning (standard single-story) | $139-$189 |
| Camera inspection with photos | $89-$129 |
| Bird guard installation | $40-$75 |
How often should I clean my dryer vent in San Dimas?
Every 12 to 18 months for most San Dimas homes, more often if you run laundry daily or your vent run is long and multi-elbow like many Via Verde original installs. The written price stays the same whether it’s been one year or five.
Is dryer vent cleaning worth it if my dryer still works fine?
Yes, because in San Dimas the vent accumulates fine ash and lint together, which compacts faster than lint alone and creates a restriction that raises dryer runtime and energy cost. Call (806) 606-6902 for a written quote.
Duct Repair & Sealing in San Dimas
Duct repair and sealing in San Dimas addresses the aging flex and sheet-metal systems common in the 1960s-1980s ranch tracts, where attic heat over 150°F causes liner breakdown and joint separation in original ductwork. When those joints open, attic dust and loose insulation fibers get pulled into the air stream your family breathes, and sealed homes running AC continuously during Santa Ana events make the problem constant rather than seasonal. Our Duct Repair & Sealing process starts with a written scope and price, and finishes with a photo record of every repaired run.
Duct Sealing
Signs you need it
Rooms that never reach the thermostat temperature, or a visible dust film on furniture within days of cleaning, point to air leaking from the duct runs before it ever reaches the register.
What it costs in San Dimas
Sealing with mastic on accessible runs costs $75-$175 per access point, plus $150-$300 per vent for sealing at the register boot where leakage is highest.
How we do it
We apply mastic sealant to every joint and seam, working from the plenum outward, then photograph each sealed point before the access is closed.
Flex Duct Repair
Signs you need it
Kinked, collapsed, or torn flex duct in your attic means either the inner liner has failed from heat or the outer jacket has been breached by rodents or handling.
What it costs in San Dimas
Replacement flex duct runs in San Dimas at $85-$135 per 10-foot section, plus $40-$75 per connection for sealing and hangers.
How we do it
We remove the failed section, size the replacement to the same diameter and R-value, and install it with proper support and newly sealed connections.
Mastic Sealant
Signs you need it
Older homes with bare sheet-metal joints sealed with fabric tape now brittle and peeling need mastic applied as a permanent replacement.
What it costs in San Dimas
Full mastic sealing of an accessible plenum and trunk line runs $300-$600 depending on the number of branch connections and access points.
How we do it
We brush mastic over every seam and joint, working from the plenum outward, and the photo record shows each sealed connection in detail.
What Duct Repair & Sealing Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Mastic sealing (per access point) | $75-$175 |
| Flex duct replacement (per 10-foot section) | $85-$135 |
| Full plenum and trunk line sealing | $300-$600 |
How do I know if my ducts actually need sealing in San Dimas?
We run a camera through the runs and photograph every joint, showing you the gaps before recommending any work. The written price covers only what the photos prove is leaking. Call (806) 606-6902 for a written scope.
Can you repair ducts without opening my San Dimas walls?
Yes, for attic and crawlspace runs we seal and repair from the access side without cutting into finished surfaces. We confirm the access route in the written scope before work starts.
Air Quality & Sanitizing in San Dimas
Air quality and sanitizing work in San Dimas targets what the foothill airshed leaves inside your ducts: wildfire ash, chaparral pollen, and fine PM2.5 particulates that standard 1-inch filters cannot capture, especially after ridgeline burns above San Dimas Canyon like the Colby Fire. When Santa Ana winds reverse normal airflow, they push this material through your HVAC system, and sealed homes running AC continuously give it a direct path into living spaces. The Air Quality & Sanitizing service addresses what remains after mechanical cleaning.
Mold Treatment
Signs you need it
Musty odor that gets stronger when the HVAC runs, or visible dark staining on register faces, indicates moisture-driven microbial growth inside your duct system.
What it costs in San Dimas
Mold treatment after mechanical cleaning runs $299-$499 for a whole-home application using EPA-registered antimicrobial products.
How we do it
We apply the treatment via fogging through open duct runs after cleaning, then photograph the registers and interior to document the work.
Odor Removal
Signs you need it
Smoke residue from wildfire season, pet dander, or previous household chemicals leave a persistent odor that returns every time the blower cycles on.
What it costs in San Dimas
Odor removal packages run $150-$300, with activated carbon or vapor-phase treatment matched to the specific odor source.
How we do it
We identify the odor source through the camera inspection, then apply the right neutralizer to the duct interior and evaporator coil surfaces.
UV Light Installation
Signs you need it
Recurring mold on the evaporator coil, or a home with respiratory concerns where the coil is constantly wet from San Dimas summer humidity, calls for UV light treatment.
What it costs in San Dimas
UV light installation runs $379-$599 for a system mounted in the supply plenum with dedicated wiring and a warranty on the lamp.
How we do it
We mount a UV lamp sized to your plenum dimensions, wire it independently, and photograph the installation with a written scope of coverage.
Air Purifier Install
Signs you need it
Homes within direct line of the canyon mouth where Santa Ana winds carry concentrated ash and pollen need filtration beyond a standard 1-inch media filter.
What it costs in San Dimas
Air purifier installation runs $400-$700 depending on the media type and whether it integrates with your existing HVAC control system.
How we do it
We install the purifier in the return or supply side per manufacturer specification, then verify airflow with the system running and document the install.
What Air Quality & Sanitizing Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Whole-home mold treatment | $299-$499 |
| Odor removal package | $150-$300 |
| UV light installation | $379-$599 |
Does air duct sanitizing actually remove wildfire smoke smell from my San Dimas home?
Yes, when the odor is resident in the duct surfaces and evaporator coil, a targeted vapor-phase treatment removes it from the source rather than masking it. Call (806) 606-6902 for a written scope.
Can I keep my San Dimas ducts clean with better filters alone?
Better filters reduce what enters the system moving forward, but they do not remove existing buildup on duct walls or the fine post-fire ash already deposited in the runs. We can size a purifier to your system as part of the written quote.
