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 Daly City, CA
Dryer vent cleaning in Daly City addresses a problem the fog makes worse than almost anywhere else in the Bay Area: lint accumulation inside vents that run through cool, damp wall cavities and attic spaces. The chronic marine layer keeps moisture present most mornings year-round, and when warm dryer exhaust hits those cool duct surfaces, lint sticks instead of blowing through. That means a vent that might flow acceptably in San Bruno can be partially blocked in Westlake. If your dryer has been taking longer than it should, call (806) 606-6902 and we’ll put a camera in the vent and show you what’s actually there before any work begins.
Why Daly City Homes Are Different
The Westlake district’s Doelger-built row houses, constructed between roughly 1948 and 1956, make up a huge share of Daly City’s housing stock. Those homes were built with sheet-metal forced-air duct runs, and many still carry original or first-generation systems. Seventy-year-old galvanized ductwork is common here, not exceptional. During heating cycles, warm air moving through cold attic ductwork creates condensation. In Daly City’s persistently humid air, that moisture has nowhere to go. Rust forms at seams. Seam separations open up. And every time the furnace runs, attic air gets pulled into those gaps and delivered into the living space. We find this pattern over and over in Westlake, St. Francis Heights, and Crocker neighborhoods. The homes look nearly identical from the street, but what’s above the ceiling varies enough that every job starts with a camera inspection, not an assumption.
Our Main Daly City Services
Daly City homeowners call us most often about two jobs: full air duct cleaning for forced-air systems, and HVAC cleaning for the furnace and coil. Both are scheduled appointments with written pricing before any work starts.
Air Duct Cleaning in Daly City
Whole-system duct cleaning here usually means working around original 1950s sheet-metal runs with decades of fog-driven condensation damage. We photograph every duct run before and after, then hand you the full photo record as part of the job file. Most Daly City jobs run four to six hours depending on the number of returns and the condition of the runs. Air Duct Cleaning in Daly City has the full breakdown, including what you can expect to see in the before photos.
HVAC Cleaning in Daly City
Furnace blowers, evaporator coils, and the plenum collect the same fine dust and moisture that the duct runs do. In Daly City, coil cleaning matters more than in drier markets because damp coils trap particles that then bake on during heating cycles. The result is reduced airflow and a system that works harder than it should. HVAC Cleaning in Daly City covers the furnace side of the equation, including multi-zone systems common in larger Westlake homes.

BeforeAfterDryer Vent Cleaning in Daly City
Dryer vent cleaning in Daly City means clearing lint from the metal duct that runs from the back of your dryer to the exterior vent cap. Most Westlake homes have short, straight runs through laundry closets, but some St. Francis Heights and Crocker properties route vents up through the roof, which traps more lint and takes longer to clean properly. The persistent fog means lint stays damp and sticky inside the run, clinging to walls and elbows instead of blowing clear. We use a rotating brush and negative-pressure extraction, then photograph the interior of the vent before and after so you can verify the run is clear. Full details on the service are on our Dryer Vent Cleaning page.
Dryer Vent Inspection
Signs you need it
Clothes that come out damp after a full cycle, or a dryer that feels unusually hot to the touch, usually mean the vent is restricted and should be inspected with a camera.
What it costs in Daly City
A visual inspection with a camera typically runs $49 to $99 in Daly City.
How we do it
We run a flexible camera from the dryer connection to the exterior cap, noting blockages, loose joints, and moisture build-up, then show you the footage.
Vent Cleaning
Signs you need it
Visible lint collecting around the exterior vent hood or a burning smell when the dryer runs indicates the vent needs cleaning.
What it costs in Daly City
Full vent cleaning from dryer to exterior runs $129 to $249 in Daly City.
How we do it
We connect a HEPA-filtered negative-pressure vacuum to the vent, then run a rotating brush through the full length to dislodge and extract packed lint.
Lint Removal
Signs you need it
A dryer that shuts off mid-cycle or takes more than one cycle to dry a normal load signals enough lint build-up to require removal.
What it costs in Daly City
Lint removal in Daly City runs $99 to $199, depending on run length and how compacted the lint has become.
How we do it
We remove the lint mass using air-driven tools and soft agitation, then photograph the now-clear run from both ends.
Bird Guard Installation
Signs you need it
If birds are nesting in or near your vent hood, you need a guard to keep them out and keep the vent flowing.
What it costs in Daly City
Bird guard installation in Daly City runs $89 to $189, including the cost of the guard.
How we do it
We replace the existing vent hood with a new hood that includes an integrated bird guard, then seal the assembly against the exterior wall.
What Dryer Vent Cleaning Costs in Daly City
| Item | Typical range in Daly City |
|---|---|
| Dryer vent inspection with camera | $49 - $99 |
| Dryer vent cleaning, full run | $129 - $249 |
| Bird guard installation | $89 - $189 |
The written price you receive before work starts covers the full job. No vent is opened, no brush is run, and no work happens until you have a number on paper. If you already have a written estimate from another company, we will put our own price next to it in writing at no cost.
How often should dryer vents be cleaned in Daly City?
Every 12 to 24 months, and more often if your vent run is long or routed through an uninsulated space, which is common in Daly City’s older stock.
Can I clean my own dryer vent?
You can clear the first few feet behind the dryer, but a full run needs a rotating brush and negative pressure to actually remove the lint, not just push it deeper.
Duct Repair & Sealing in Daly City
Duct repair and sealing in Daly City is often the single most effective thing a homeowner can do for a forced-air system that’s still working hard but delivering weak airflow. The original galvanized ducts in Doelger-era homes were assembled with slip joints that were never airtight to begin with, and decades of fog-driven condensation have rusted many of those seams open. What we find with a camera is gaps at elbows and takeoffs, seams that have separated enough to pull attic air, and runs that have collapsed under old insulation. Sealing those leaks means the furnace stops heating the attic and starts heating the rooms you actually use. See our Duct Repair & Sealing page for the full scope.
Duct Sealing
Signs you need it
Rooms that never reach the thermostat temperature, even with the furnace running, suggest leaks in the duct runs.
What it costs in Daly City
Duct sealing in Daly City runs $40 to $160 per run, depending on access and the condition of the existing seams.
How we do it
We locate leaks with a pressure test or camera, then seal seams and joints with mastic or metal tape rated for ductwork.
Flex Duct Repair
Signs you need it
A collapsed or torn flex duct in the attic will starve entire rooms of airflow, and can often be seen as a sagging section from the attic access.
What it costs in Daly City
Flex duct repair or replacement in Daly City runs $20 to $50 per linear foot.
How we do it
We remove the damaged section, replace it with properly sized flex duct, seal the connections, and test the run for flow.
Metal Duct Repair
Signs you need it
Rusted seam separations or visible holes in exposed sheet-metal ducts mean attic air is being pulled directly into the system.
What it costs in Daly City
Metal duct repair in Daly City runs $40 to $160 per run, including seam closing and corrosion treatment.
How we do it
We close rusted seams with mechanical fasteners and mastic, then inspect the full run with a camera to confirm no gaps remain.
What Duct Repair & Sealing Costs in Daly City
| Item | Typical range in Daly City |
|---|---|
| Duct sealing per run | $40 - $160 |
| Flex duct repair or replacement | $20 - $50 per linear foot |
| Metal duct repair per run | $40 - $160 |
Homes with long attic runs, very tight access, or rust damage throughout will come in at the higher end. Every job gets a written price before work starts, under Haven Standard Clause 1. No exceptions.
Can duct sealing lower my heating bills in Daly City?
Yes. When the furnace is no longer heating the attic, the system delivers more of what it produces to the living space, which means shorter cycles and less fuel used.
How do I know if my ducts need sealing?
If some rooms are consistently colder than others, or you see visible gaps at metal joints in the attic, the duct system is leaking and should be sealed.
Air Quality & Sanitizing in Daly City
Air quality and sanitizing in Daly City means treating the inside of the duct system and the air itself for what the fog leaves behind: mold spores, bacteria, and the musty smell that comes from decades of elevated humidity moving through metal ducts. Doelger-era homes with original ductwork often develop organic growth inside the runs, especially at the first elbow after the plenum where warm air meets cool metal. That growth is not always visible from the register, which is why we camera-inspect first, then treat what is actually present, not what we assume is present. Our Air Quality & Sanitizing page covers the full process.
Mold Treatment
Signs you need it
A musty smell that gets stronger when the furnace runs is the most common sign of mold inside the duct runs.
What it costs in Daly City
Mold treatment inside ductwork in Daly City runs $250 to $500, depending on the number of runs affected.
How we do it
We apply an EPA-registered antimicrobial treatment inside the duct runs with a fogger, then photograph the treated surfaces for the job record.
Odor Removal
Signs you need it
Persistent cooking, pet, or smoke odors that return whenever the fan runs usually mean the source is inside the ducts.
What it costs in Daly City
Odor removal in Daly City runs $150 to $350 per treatment, depending on square footage and odor source.
How we do it
We fog the full duct system with an odor-neutralizing agent, then run the fan to pull the treatment through every register.
UV Light Installation
Signs you need it
If the evaporator coil grows visible mold or the home has recurring musty smells despite cleaning, a UV light at the coil is the long-term fix.
What it costs in Daly City
UV light installation in Daly City runs $450 to $1,200, including the unit and the electrical connection.
How we do it
We install a UV lamp inside the supply plenum aimed at the coil, wire it to the furnace circuit, and confirm operation before leaving.
What Air Quality & Sanitizing Costs in Daly City
| Item | Typical range in Daly City |
|---|---|
| Mold treatment inside ductwork | $250 - $500 |
| Odor removal treatment | $150 - $350 |
| UV light installation | $450 - $1,200 |
The persistent humidity in Daly City means air quality work is often paired with duct sealing, since the moisture that feeds mold enters through the same gaps that leak air. We’ll tell you what’s actually needed and what isn’t.
Will sanitizing get rid of the musty smell in my Daly City ducts?
In most cases, yes. The treatment neutralizes the organic matter causing the odor, but if the source is standing water in a duct run, that run must be repaired or dried first.
Is the sanitizing product safe for my family?
We use EPA-registered products applied according to manufacturer guidelines, and we run the fan to distribute the treatment before recommending you re-occupy the space.
