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 Fontana, CA
Dryer vent cleaning in Fontana is not a routine chore here, it is a safety requirement driven by housing stock and air conditions that are measurably harsher than most of Southern California. Most Fontana homes were built between the 1980s and 2000s with long flex-duct dryer vents that sag, separate, and trap lint at rates far beyond older rigid-metal systems. Add the diesel particulate load from the I-10/I-15 freight corridor and the Inland Valley’s inversion layer, and a dryer vent can become fully obstructed in under two years. Call (806) 606-6902 for a written price before any work begins.
Why Fontana Homes Are Different
Fontana sits at the crossroads of two of North America’s busiest diesel freight routes, and the South Coast AQMD consistently ranks Fontana-area zip codes among the highest in California for diesel particulate exposure. That soot does not stay outside. It gets pulled through wall cavities, window seals, and HVAC returns, and it settles inside ductwork as a gray-black film that no standard filter stops. Technicians working near Cherry Avenue and the former Kaiser Steel footprint regularly pull duct debris with a distinctly dark diesel coloration, visibly different from the tan desert dust found a few miles west. This is not cosmetic dirt. It is a measurable particulate load that changes how often ducts and vents actually need service in Fontana.
The housing stock compounds the problem. The bulk of Fontana’s residential construction is 1980s-to-2000s tract housing, stucco over wood frame with flex-duct HVAC systems now 20 to 40 years old. Flex duct sags between supports, joints separate, and return paths pull unfiltered attic air. In the older neighborhoods near the original Kaiser Steel worker housing, 1950s and 60s homes still run sheet-metal ductwork with decades of compacted dust and, in some cases, deteriorated duct insulation shedding fibers into the airstream. The San Gabriel and San Bernardino mountains form a wall that traps the Inland Valley air basin, so thermal inversions concentrate particulates directly over Fontana instead of dispersing them. Fall Santa Ana events then surge fine desert and wildfire particulates into duct systems within hours.
Our Main Fontana Services
Two services draw the most calls from Fontana homeowners, and each has its own dedicated page with full local pricing and detail.
Air Duct Cleaning in Fontana
Air duct cleaning in Fontana addresses the diesel soot and fine particulate accumulation that builds faster here than nearly anywhere in the region. In tract homes with flex duct, we photograph every run before and after, and the difference is usually stark: gray-black films at the plenum and first elbows, compacted dust in low spots, and visible particulate on supply registers. Fontana’s inversion layer means what settles is not just desert dust, it is diesel PM2.5 from the warehouse corridor and freeway network. The full local cost breakdown, photos, and scope of work live on the dedicated page.
HVAC Cleaning in Fontana
HVAC cleaning in Fontana goes beyond the ducts to the blower motor, evaporator coil, and condensate pan, the components that recirculate whatever the filters miss. In a 30-year-old Fontana tract home, a coated blower wheel can cut airflow by 25 percent or more, forcing longer runtimes and pulling more unfiltered air through the system. Warehouse-corridor homes near Cherry Avenue usually show a fine gray-black coating on coil surfaces that no filter change ever removes. Full pricing and the documented record of what we clean live on the dedicated Fontana page.

BeforeAfterDryer Vent Cleaning in Fontana
Dryer vent cleaning in Fontana solves a measurable fire-safety problem. Long flex-duct runs common in 1980s-to-2000s tract homes trap lint at every sag and elbow, and when that lint mixes with the fine diesel dust that settles over the city, the vent can clog in as little as eighteen months. Clogged vents make dryers run longer, overheat, and in the worst case ignite accumulated lint. Our Dryer Vent Cleaning service starts with a written price and ends with photographs of the inside of the vent, before and after.
Dryer Vent Inspection
Signs you need it
Clothes take two or more cycles to dry, the dryer exterior feels hot to the touch during operation, or you can smell a musty odor when the dryer runs.
What it costs in Fontana
Dryer vent inspection in Fontana typically costs $59 to $135 as a standalone job, and it is credited toward cleaning if we do that work the same visit.
How we do it
We run a camera from the dryer connection to the roof or wall termination, photograph every obstruction and joint separation, and hand you a written scope with the images.
Lint Removal
Signs you need it
Visible lint escaping from the exterior vent cap, a burning smell while the dryer runs, or a vent flap that rarely opens during cycles.
What it costs in Fontana
Lint removal in Fontana typically runs $89 to $250 depending on vent length, number of elbows, and whether the exit is at roof level or through a wall.
How we do it
We use a HEPA-filtered negative-pressure vacuum at the dryer connection and run a rotating brush through the full vent length, then photograph the exit point before and after.
Vent Rerouting
Signs you need it
The current vent path has too many elbows, runs longer than 25 feet, or terminates in a spot that keeps getting blocked by debris or bird activity.
What it costs in Fontana
Vent rerouting in Fontana usually falls between $320 and $600 depending on the new path length, roof or wall penetration, and the number of elbows eliminated.
How we do it
We redesign the vent path to the shortest code-compliant run, replace flex sections with rigid metal where accessible, and document the full new path with photos.
Bird Guard Installation
Signs you need it
You hear birds in the vent, spot nesting material at the exterior cap, or have removed a nest from the vent more than once.
What it costs in Fontana
Bird guard installation in Fontana typically costs $120 to $300 per vent including the stainless or galvanized guard and attachment hardware.
How we do it
We clear any existing nesting material, install a screened guard with openings small enough to block birds but large enough for proper airflow, and photograph the final result.
What Dryer Vent Cleaning Costs in Fontana
| Item | Typical range in Fontana |
|---|---|
| Dryer Vent Inspection | $59 - $135 |
| Lint Removal | $89 - $250 |
| Bird Guard Installation | $120 - $300 |
How often should a dryer vent be cleaned in Fontana?
Every 18 to 24 months for most Fontana homes, and every 12 months if the vent run is over 20 feet or the home sits near the warehouse corridor around Cherry Avenue. Diesel dust shortens the safe interval noticeably.
Does a clogged dryer vent really cause house fires?
Yes. Lint is highly flammable, and a clogged vent makes the dryer overheat. The U.S. Fire Administration attributes thousands of dryer fires annually to lint accumulation in the vent path. Call (806) 606-6902 if you cannot remember your last cleaning.
Duct Repair & Sealing in Fontana
Duct repair and sealing in Fontana targets a specific failure pattern: flex-duct systems in 20-to-40-year-old tract homes that sag between supports, separate at joints, and leak conditioned air into hot attics. The leaks pull unfiltered attic air and diesel soot into the supply stream, so rooms never reach temperature and dust accumulates on registers within days of cleaning. Our Duct Repair & Sealing service starts with a written price and includes a before-and-after photo record of every repaired section.
Duct Sealing
Signs you need it
Some rooms are always hotter or colder than others, dust reappears on registers soon after cleaning, or energy bills climb even though usage has not changed.
What it costs in Fontana
Duct sealing in Fontana typically runs $450 to $1,900 depending on system size, number of leaks found during testing, and whether we seal from inside or outside the duct.
How we do it
We pressurize the duct system to locate every leak, seal accessible joints with mastic, and photograph each repair before and after.
Flex Duct Repair
Signs you need it
Visible sagging in attic duct runs, crushed sections from storage or foot traffic, or disconnected ducts at the plenum or register.
What it costs in Fontana
Flex duct repair in Fontana usually falls between $200 and $950 for a single repair, with the range driven by run length, accessibility, and whether the existing duct can be reattached or must be replaced.
How we do it
We replace crushed or separated flex sections, support sagging runs with proper strapping, and seal connections with mastic and UL-listed tape.
Mastic Sealant
Signs you need it
Old duct tape is peeling or brittle at joints, visible gaps exist at register boxes, or airflow smells dusty or attic-like.
What it costs in Fontana
Mastic sealing in Fontana typically costs $350 to $1,600 depending on duct length, number of joints accessible from the attic or crawlspace, and how much of the system needs resealing.
How we do it
We apply fiber-reinforced mastic to every accessible joint and register box connection, then run a pressure test to verify the sealed system holds air.
What Duct Repair & Sealing Costs in Fontana
| Item | Typical range in Fontana |
|---|---|
| Duct Sealing | $450 - $1,900 |
| Flex Duct Repair | $200 - $950 |
| Mastic Sealant | $350 - $1,600 |
Is duct sealing worth the cost in Fontana’s climate?
Usually, yes. Fontana attics routinely reach 130°F in summer, so leaking ducts pull that heat into the supply stream and force the AC to run longer. Sealed ducts often pay for themselves in reduced cooling cost within two to three summers.
Can you repair ducts in a Fontana attic without removing insulation?
Yes, in most cases. We work around existing insulation, photograph every repair, and restore any insulation we move. Full replacement only happens when a section is crushed or separated beyond repair. Call (806) 606-6902 for a written price.
Air Quality & Sanitizing in Fontana
Air quality and sanitizing in Fontana addresses what keeps coming back after cleaning: fine diesel soot, mold spores, and bacteria that re-enter ducts through leaky returns and high indoor humidity. Fontana’s inversion layer holds particulates over the city for days, so the air residents breathe inside their homes contains whatever is outside, filtered only as well as the home’s HVAC allows. Our Air Quality & Sanitizing service treats the surfaces and the airstream itself, with a written price and a documented before-and-after record.
Mold Treatment
Signs you need it
Musty odors when the AC runs, visible fungal growth inside the supply registers or on duct insulation, or allergy symptoms that worsen only at home.
What it costs in Fontana
Mold treatment in Fontana typically runs $400 to $2,200 depending on the affected area, whether duct insulation must be removed, and how many duct runs show growth.
How we do it
We photograph every affected surface, apply an EPA-registered antimicrobial treatment, and replace any insulation that cannot be effectively treated.
UV Light Installation
Signs you need it
Recurring microbial growth on the coil or in the condensate pan, persistent biological odors, or a household member with mold or bacterial sensitivity.
What it costs in Fontana
UV light installation in Fontana usually falls between $600 and $1,600 per unit depending on lamp strength, mounting location, and whether we install the light in the supply plenum or at the coil.
How we do it
We mount a Honeywell or Aprilaire UV lamp at the coil or supply plenum, wire it to run continuously, and photograph the installation and lamp placement.
What Air Quality & Sanitizing Costs in Fontana
| Item | Typical range in Fontana |
|---|---|
| Mold Treatment | $400 - $2,200 |
| UV Light Installation | $600 - $1,600 |
Does UV light actually kill mold in Fontana ducts?
UV light is effective against surface mold and bacteria on the coil and in the supply plenum when properly sized and positioned. It does not remove existing particulate deposits, so we combine it with cleaning for real results.
Will sanitizing get rid of the diesel smell in my Fontana ducts?
Sanitizing alone will not remove the odor source. The diesel soot itself must be physically extracted from the duct walls first, then treatment prevents what remains from regrowing. Call (806) 606-6902 for a written scope.
Brands We Service in Fontana
We service and install equipment from Honeywell, Aprilaire, and Guardsman, among others. The brands we carry are selected for durability under Fontana’s particulate load and for parts availability across the Inland Empire. Most replacement parts are stocked locally or arrive within two business days.

FAQs About Air Duct Cleaning in Fontana
Most Fontana jobs are scheduled within one to two business days. We give you a written price before anything starts, so the first visit is the work visit, not a sales call.
Work inside the home or inside the attic needs no HOA approval. Exterior vent terminations, bird guards, or rerouting through an exterior wall may require an architectural request if your HOA governs exterior changes. We can provide a written scope to attach to your submission.
Fontana sits at the convergence of I-10 and I-15 and hosts one of the densest warehouse concentrations in the country. Diesel soot and PM2.5 settle into ductwork faster here than in cities without the same freight traffic and inversion layer, which is why we photograph every run before and after.
