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 Walnut, CA
Dryer vent cleaning in Walnut runs $135-$190 and is done the same day we inspect it. The homes here, most built between the late 1970s and early 1990s on large lots, carry original or aging ductwork that pulls heavy particulate loads from the Puente Hills air trap and the SR-60 corridor. CleanRun Air Duct Cleaning photographs every duct run before and after, and every job starts with a written price, not an estimate you have to chase. Call (806) 606-6902.
Why Walnut Homes Are Different
Walnut sits where the Puente Hills stop the prevailing westerly winds, so the air that reaches these neighborhoods has already picked up everything the LA Basin produces: smog, diesel particulates from the City of Industry warehouse district, and fine PM2.5 that settles against the hillside. Homes here pull that air through their HVAC systems all summer, when temperatures routinely pass 100°F and AC runs near-continuously from June through September.
The housing stock compounds the problem. Most Walnut homes are 2,500 to 4,500 square feet, built from the late 1970s through the early 1990s with original flex duct or ductboard. Those are long duct runs by any standard, and after 30 to 45 years they hold a lot of material: construction dust, pet dander, pollen, and the ultrafine particulate matter that diesel trucks on SR-60 deposit directly upwind of residential streets. Technicians working the neighborhoods near Nogales Street and the 60 freeway consistently pull darker debris loads than jobs of the same house age in Diamond Bar or Rowland Heights.
That means duct cleaning in Walnut is not a cosmetic service. It is the difference between breathing filtered air and recirculating a few decades of accumulated contamination through every room.
Our Main Walnut Services
Walnut homeowners call us most often about two things: the full air duct cleaning their aging systems need, and HVAC cleaning that gets the evaporator coils, blower, and plenum back to functioning condition. Both are documented with photos and priced in writing before any panel comes off.
Air Duct Cleaning in Walnut
Whole-system cleaning for homes where the ducts have never been serviced or where a remodel has pushed drywall dust and debris through every register. In Walnut, the larger floor plans mean longer duct runs and more surface area for buildup, so the job typically takes a full day. We use negative-pressure extraction with Rotobrush and Nikro equipment, photograph every run before and after, and hand you the photo record as part of the standard job file. Air Duct Cleaning in Walnut covers the full scope, pricing, and what to expect on the day.
HVAC Cleaning in Walnut
Cleaning the mechanical side of the system: evaporator coils, blower fan, drain pan, and the plenum where air enters the duct network. Walnut’s summer heat means coils work harder and collect more biofilm, which reduces cooling capacity and forces the system to run longer. We clean the components with professional-grade equipment, document the condition of each part, and leave you with written notes on what was found. HVAC Cleaning in Walnut has the full breakdown.

BeforeAfterDryer Vent Cleaning in Walnut
Dryer vent cleaning in Walnut costs $135-$190 for a standard single-family home, and most jobs take under two hours. The homes here, built from the late 1970s through the early 1990s, often have long vent runs from the laundry room to the exterior wall, and the combination of lint, dust, and the fine particulate matter that settles against the Puente Hills makes those runs clog faster than vents in coastal cities. A clogged dryer vent drives up drying times, overheats the dryer, and creates a fire hazard in a house full of 30 to 45-year-old building materials. Dryer Vent Cleaning is the service we recommend every Walnut homeowner schedule at least once every two years.
Dryer Vent Inspection
Signs you need it
Clothes take two or three cycles to dry, the dryer shuts off mid-cycle on overheat, or you can feel warm air backing up around the dryer while it runs.
What it costs in Walnut
A standalone inspection is $79, and the amount is credited toward cleaning if we find a blockage that needs to be removed.
How we do it
We run a camera through the full vent run from the dryer connection to the exterior termination, measuring airflow resistance with a manometer and documenting every bend and restriction in the photo record.
Vent Cleaning
Signs you need it
The exterior vent flap does not open when the dryer runs, the laundry room feels humid and lint-dusted, or the dryer has not been vented out in more than two years.
What it costs in Walnut
Standard vent cleaning runs $135-$190 depending on run length, and the written price is delivered before any work starts.
How we do it
We use a rotating brush and HEPA-filtered negative-pressure collection to pull lint, debris, and the fine dust Walnut’s air deposits into the vent, then photograph the full run before and after from both ends.
Lint Removal
Signs you need it
You can see lint building up around the dryer drum or the exterior vent hood, or a previous cleaning left visible lint behind.
What it costs in Walnut
Targeted lint removal from a clogged section runs $95-$145, and the price is set before the work begins.
How we do it
We locate the lint accumulation with the camera, open the vent at the nearest accessible point, and remove the blockage with a brush and vacuum system that traps what it pulls out.
Vent Rerouting
Signs you need it
The vent run makes multiple sharp turns, terminates in a hard-to-reach roof location, or the existing flex vent is crushed or kinked behind the wall.
What it costs in Walnut
Rerouting work starts at $225 and is quoted as a fixed price once we can see the access and the run length.
How we do it
We map a straighter route, replace kinked flex with rigid or semi-rigid duct where practical, and seal each connection with aluminum tape and mastic before testing the airflow with the dryer running.
Bird Guard Installation
Signs you need it
You hear birds or scratching near the exterior vent, or the last cleaning pulled nest material out of the run.
What it costs in Walnut
Bird guard installation runs $85-$150 including the guard, and it is a fixed price item on every written quote.
How we do it
We install a galvanized or stainless steel guard over the exterior termination, secure it so it cannot be dislodged, and test the airflow so the dryer still vents freely.
What Dryer Vent Cleaning Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Dryer vent inspection | $79 (credited toward cleaning) |
| Standard dryer vent cleaning | $135-$190 |
| Lint removal / clog clearing | $95-$145 |
How often should dryer vents be cleaned in Walnut?
Every one to two years. The air conditions in Walnut deposit more particulate matter into vent runs than coastal cities do, and Santa Ana wind events push additional dust and wildfire smoke through the valley. We document every cleaning with photos so you have a record of when it was done.
Does a clogged dryer vent really increase drying time in Walnut’s climate?
Yes. Restricted airflow forces the dryer to run longer to remove moisture from clothes, and Walnut’s already warm indoor air makes the dryer work harder. Most households see a measurable drop in drying time the same day the vent is cleaned. Call (806) 606-6902 for a fixed quote and we will photograph the blockage before we remove it.
Duct Repair & Sealing in Walnut
Duct repair and sealing in Walnut runs $450-$2,500 depending on what the camera finds. Homes built in the 1970s through early 1990s here were fitted with flex duct and ductboard that is now beyond its intended service life, and the result is conditioned air leaking into attics and crawlspaces while dust from the attic gets pulled into the living space. Santa Ana wind events and the near-continuous summer AC run make those leaks more costly than homeowners realize. Duct Repair & Sealing is a fixed-price service, quoted before any work starts.
Duct Sealing
Signs you need it
Rooms at the far end of the house never reach the thermostat temperature, the system runs constantly, dust accumulates quickly, or you can feel air moving around the duct connections in the attic.
What it costs in Walnut
Duct sealing runs $450-$1,400 depending on the number of accessible registers and the condition of the existing seals.
How we do it
We locate leaks with a pressure test or a manual inspection using the camera, then apply mastic sealant and foil tape at every joint, connection, and register boot.
Flex Duct Repair
Signs you need it
A section of flex duct is crushed, sagging, torn, or has pulled loose from a collar, which you may notice as a hot or cold spot in a specific room.
What it costs in Walnut
Flex duct repair runs $250-$750 depending on the number of sections replaced and the access difficulty.
How we do it
We cut out the damaged section, install a new piece of properly sized flex duct, pull it taut to maintain airflow, and seal both collar connections with mastic.
Metal Duct Repair
Signs you need it
You hear a rattling or banging when the system starts up, or visible rust and corrosion appear on the exposed duct sections in the garage or attic.
What it costs in Walnut
Metal duct repair runs $300-$900 for typical sectional replacement or seam re-sealing work.
How we do it
We replace the damaged metal section, re-seal the longitudinal seams with mastic and foil tape, and mechanically fasten the connections so the duct cannot separate under pressure.
Duct Insulation
Signs you need it
You can feel the attic heat radiating into rooms below, the AC does not cool effectively in summer, or the existing duct insulation is torn, compressed, or missing in sections.
What it costs in Walnut
Duct insulation runs $300-$1,200 depending on the linear footage and whether we are insulating new duct or re-wrapping existing runs.
How we do it
We assess the existing insulation thickness, remove deteriorated material, and install new fiberglass or reflective insulation sized to the duct diameter, sealing the longitudinal seams as we go.
Mastic Sealant
Signs you need it
The current seals are cracked, dried out, or visibly failing, and you want a permanent fix rather than another round of foil tape.
What it costs in Walnut
Mastic application runs $200-$600 as a standalone service, and it is included in every duct sealing job we quote.
How we do it
We brush mastic onto every accessible joint and seam, working it into the gaps so it dries hard and forms an airtight, permanent seal.
What Duct Repair & Sealing Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Duct sealing | $450-$1,400 |
| Flex duct repair | $250-$750 |
| Duct insulation | $300-$1,200 |
Are duct leaks really costing me money in Walnut?
Yes. Walnut’s summer temperatures mean your AC runs nearly constantly from June through September, and every cubic foot of conditioned air that escapes into the attic is a cubic foot you paid to cool. Sealing the ducts pays for itself in efficiency during a single cooling season.
Can you repair ducts in a cramped Walnut attic?
Yes. Most Walnut homes built in the 1970s through 1990s have accessible attic ductwork, though the larger floor plans mean longer runs and sometimes tight clearance at the eaves. We document what we find with the camera before quoting a fixed price. Call (806) 606-6902 and bring us a competitor’s written estimate for a free second opinion.
Air Quality & Sanitizing in Walnut
Air quality and sanitizing in Walnut runs $250-$900 depending on the system size and the treatment scope. The Puente Hills air trap and the SR-60 diesel corridor push fine particulate matter into homes here, and that material settles in ductwork, on coils, and in the plenum where it becomes a breeding ground for bacteria and mold. A single Santa Ana wind event can push wildfire smoke, dust, and airborne contaminants through every register in the house. Air Quality & Sanitizing is a fixed-price service backed by our 365-Day Done Right Promise.
Mold Treatment
Signs you need it
You see or smell mold around the registers, in the ductwork, or on the evaporator coil, or a recent leak or humidity problem has left visible growth inside the system.
What it costs in Walnut
Mold treatment runs $400-$1,200 depending on the affected surface area and whether the coil, plenum, or duct runs are involved.
How we do it
We identify the affected areas with the camera, apply an EPA-registered antimicrobial treatment to the affected surfaces, and photograph every treated section so you have a complete record of what was done.
Bacteria Sanitizing
Signs you need it
A musty or sour smell comes from the vents when the system starts, family members have unexplained allergy symptoms indoors, or the condensate pan has standing water.
What it costs in Walnut
Bacteria sanitizing runs $250-$600 for the full system, depending on the number of registers and the coil size.
How we do it
We fog the ductwork and the mechanical components with a professional antimicrobial from Abatement Technologies, then document the treated areas in the photo record.
Odor Removal
Signs you need it
A smell from cooking, pets, smoke, or previous moisture damage lingers in the house even after the source is gone.
What it costs in Walnut
Odor removal runs $300-$700 depending on the system size and whether the odor is organic, chemical, or smoke-based.
How we do it
We clean the surfaces holding the odor, then use an odor-neutralizing treatment that binds and removes the source rather than masking it with fragrance.
UV Light Installation
Signs you need it
Mold or bacteria keep returning after treatment, or someone in the home has a respiratory condition that makes ongoing microbial control a priority.
What it costs in Walnut
UV light installation runs $500-$1,200 depending on the unit and the installation location, and we supply units from recognized trade brands.
How we do it
We install the UV lamp in the return or supply plenum where it can treat the air passing over the coil, wire it to run with the system, and document the installation in the job record.
Air Purifier Install
Signs you need it
Household members have allergies or asthma that indoor air quality makes worse, or you want whole-house filtration to handle Walnut’s particulate-heavy air.
What it costs in Walnut
Air purifier installation runs $450-$1,800 depending on the purifier type, size, and the electrical work involved.
How we do it
We install the purifier in the supply or return ductwork, wire it into the HVAC system, and document the placement and performance settings before we leave.
What Air Quality & Sanitizing Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Bacteria sanitizing | $250-$600 |
| Odor removal | $300-$700 |
| UV light installation | $500-$1,200 |
Why does Walnut’s air quality make sanitizing more important?
The Puente Hills trap the LA Basin’s smog and particulate matter against the hillside, and the SR-60 diesel corridor adds ultrafine particles directly upwind of residential streets. That material accumulates in ductwork faster here than in coastal LA communities, and it carries the fuel for microbial growth. Call (806) 606-6902 for a written quote.
Will the treatment leave a smell or residue?
No. The antimicrobial products we use dry clean and leave no lingering odor or visible residue, and we photograph every treated surface so you can see exactly what was applied. The 365-Day Done Right Promise covers the work in writing.
Brands We Service in Walnut
We service and restore equipment from Honeywell, Aprilaire, and Guardsman, and we install components from trade-recognized manufacturers including Rotobrush and Nikro. Parts for common systems are stocked locally, and most replacement work is completed the same week. Our brands page lists every manufacturer we work with.
