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.
Air Duct Cleaning in Mission District, CA
Dryer vent cleaning in Mission District homes runs $130-$210 for a standard single-run system, with most jobs finished in 60-90 minutes. The real difference here is the building stock: Victorian and Edwardian flats with retrofit ductwork jammed into damp crawlspaces collect lint and moisture faster than any new construction. Call (806) 606-6902 for a written price before anyone touches your system.
Why Mission District Homes Are Different
The Mission’s housing predates forced-air HVAC by decades. Most flats along Dolores, Guerrero, and Valencia were built between 1890 and 1915, and when heating was retrofitted in the mid-20th century, ducts got shoehorned into wall cavities and unventilated subfloor crawlspaces that were never designed for them. Flex duct crammed through undersized voids is a standard finding on our camera inspections, and it collects condensation, debris, and mold at rates far exceeding purpose-built systems in SOMA or Potrero Hill.
Add the microclimate: Mission District sits in San Francisco’s warmest, sunniest pocket, sheltered from the marine layer by Twin Peaks. But nighttime temperatures still drop enough to cause condensation inside poorly sealed retrofit ducts. For dryer vents and air handlers alike, that moisture feeds mold growth that East Bay operators rarely document at the same frequency. Along the Mission Street and South Van Ness corridor, we also see noticeably heavier carbon soot in duct intakes from high-frequency Muni bus routes and diesel truck traffic, a condition that runs one or two blocks west to Valencia or Guerrero and drops off sharply.
Our Main Mission District Services
Two services dominate the call log from Mission District homeowners: full air duct cleaning and complete HVAC system cleaning. Both address what our camera crews find in pre-1906 and interwar building stock.
Air Duct Cleaning in Mission District
Full air duct cleaning in Mission District typically runs $380-$560 for a single-system home, with the final number written before work begins. Our crews document every run with before-and-after photos, including the plenum, supply registers, and return drops where retrofit flex duct tends to sag and trap debris. For Mission flats with short, sharply angled runs, we use negative-pressure extraction with a Rotobrush system sized for tight-access voids. See Air Duct Cleaning in Mission District for the full service breakdown.

HVAC Cleaning in Mission District
HVAC cleaning in Mission District covers the blower motor, evaporator coil, drain pan, and the full plenum assembly, priced at $320-$520 for a standard single-zone system. Condensation is the recurring theme here: coils in older Mission buildings sit inside closets or attic spaces with minimal airflow, and the resulting moisture bonds dust into a paste that cuts efficiency and feeds mold. Our written scope lists every component before we start, and the photo record shows each one after. Full details are on our HVAC Cleaning in Mission District page.

Before
AfterDryer Vent Cleaning in Mission District

Dryer vent cleaning in Mission District runs $130-$210 for a single-run system, with the written price set before any panel comes off. In a neighborhood where dryers often vent through long, narrow wall cavities in pre-1920s flats, the lint accumulation we pull out is consistently denser than what you’d find in newer construction. The Mission’s cool, damp night air condenses inside those runs, turning lint from a loose accumulation into a compacted blockage that restricts airflow and raises drying times. Our Dryer Vent Cleaning technicians photograph the inside of every run before and after, so you see exactly what was removed.
Dryer Vent Inspection
Signs you need it
Clothes take more than one full cycle to dry, or the dryer feels hot to the touch while the laundry stays damp, which signals a restricted or damaged vent run.
What it costs in Mission District
Inspection alone starts at $75, credited toward cleaning if we do the work same visit.
How we do it
We run a camera through the full duct run from the dryer connection to the exterior termination, measure airflow and static pressure, and hand you the written findings with photos before price is discussed.
Vent Cleaning
Signs you need it
Visible lint at the exterior vent hood, a burning smell when the dryer runs, or the dryer shuts off mid-cycle from overheating.
What it costs in Mission District
Standard vent cleaning for a single run is $130-$210, with multi-story or long-run flats priced by measured footage.
How we do it
We connect a professional rotary brush and HEPA-filtered extraction unit at the dryer end, work the full length of the run, then clean the termination hood and verify airflow with a pressure reading.
Lint Removal
Signs you need it
A noticeable decrease in dryer performance within months of a previous cleaning, which typically means a hidden blockage deeper in the run or a partially collapsed flex duct.
What it costs in Mission District
Standalone lint removal from a severely obstructed run runs $150-$200, depending on run length and access.
How we do it
We start with the camera to locate the deposit, remove the compacted material with rotating brushes under negative pressure, and document the clear run with post-extraction photos.
Vent Rerouting
Signs you need it
The current vent exits into a crawlspace, attic, or interior wall cavity, or the run exceeds 25 feet with more than two elbows, which codes and manufacturer specs both flag as a hazard.
What it costs in Mission District
Rerouting a vent in Mission District starts at $380 and rises with wall penetrations and run length, quoted in writing after the inspection.
How we do it
We map the new route, cut the required penetrations, install rigid metal ducting with proper slope to the exterior, and seal every joint with foil tape before reconnecting the dryer.
Bird Guard Installation
Signs you need it
Nesting material visible at the exterior vent hood, or chirping sounds near the duct termination during spring nesting season.
What it costs in Mission District
Bird guard installation runs $60-$110, including removal of existing nesting debris from the immediate termination area.
How we do it
We clear the hood, install a corrosion-resistant guard sized for your existing duct diameter, and verify airflow remains within manufacturer spec before finishing.
What Dryer Vent Cleaning Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Dryer vent inspection | $75 |
| Standard vent cleaning | $130-$210 |
| Bird guard installation | $60-$110 |
How often should dryer vents be cleaned in Mission District?
Every 12 months minimum for Mission District flats with retrofit runs. Older, longer ducts in Victorian buildings with multiple elbows should be checked every 6 months. Our camera inspection gives you a factual answer for your own run.
Why does my dryer take so long in a Mission District flat?
Long, narrow vent runs through pre-1920s wall cavities are the usual cause. Add cool nighttime condensation that paste lint into blockages, and airflow drops sharply. We document the before and after so you see the restriction is gone. Call (806) 606-6902.
Duct Repair & Sealing in Mission District

Duct repair and sealing in Mission District runs $220-$520 per run for most retrofit systems, priced in writing after a camera inspection. The problem specific to this housing stock is access: ducts in Victorian and Edwardian flats were retrofitted into wall voids and crawlspaces never engineered for them, so joints fail, flex duct sags, and air leaks into unventilated dead spaces instead of reaching registers. Our Duct Repair & Sealing crews photograph every failed joint and every finished seal before you owe a dollar.
Duct Sealing
Signs you need it
Some rooms never reach the thermostat setting while others overheat, or utility bills climb seasonally with no change in usage patterns, both classic leaks in the run.
What it costs in Mission District
Duct sealing runs $220-$520 per run, with multi-run systems priced by total footage after the camera inspection.
How we do it
We locate every leak with a pressure test and visual inspection, then apply mastic sealant and foil tape at each joint, followed by a repeat pressure measurement to confirm the improvement.
Flex Duct Repair
Signs you need it
Crushed, kinked, or disconnected flex duct visible in the crawlspace or attic, often flagged by our camera during a routine cleaning inspection.
What it costs in Mission District
Flex duct repair runs $300-$380 per section when replacement is required, including new R-6 or R-8 flex duct and all connections.
How we do it
We cut out the damaged section, install new insulated flex duct with proper support straps every 4 feet, and seal both terminations with mastic before re-testing airflow.
Metal Duct Repair
Signs you need it
Rusted, punctured, or detached sheet metal runs, especially common in Mission District crawlspaces where ground moisture accelerates corrosion.
What it costs in Mission District
Metal duct repair starts at $400 per section and rises with replacement length and access difficulty.
How we do it
We replace the damaged metal section with matching-gauge galvanized duct, crimp and seal each connection with mastic and foil tape, and secure the run with proper hangers.
Duct Insulation
Signs you need it
Condensation beading on duct surfaces, visible rust at seams, or supply air arriving noticeably warmer or cooler than the plenum output.
What it costs in Mission District
Duct insulation for exposed runs is $6-$10 per linear foot, with typical Mission District jobs totaling $240-$400 for a single-zone system.
How we do it
We wrap accessible runs with R-6 or R-8 fiberglass insulation, vapor barrier facing outward, and seal all seams with approved tape to keep moisture out.
Mastic Sealant
Signs you need it
Visible gaps at duct joints, or a pressure test showing more than 10% leakage, the threshold we flag as worth correcting in older Mission retrofit systems.
What it costs in Mission District
Mastic-only sealing for a single accessible duct run is $220-$320, depending on joint count and access.
How we do it
We clean each joint, apply a continuous mastic bead around the full circumference, and allow proper cure time before re-pressurizing the system to verify the leak rate dropped.
What Duct Repair & Sealing Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Duct sealing | $220-$520 per run |
| Flex duct repair | $300-$380 per section |
| Duct insulation | $6-$10 per linear foot |
How do I know my ducts are leaking in Mission District?
Uneven room temperatures, dust accumulation near registers, and higher-than-expected utility bills are the three most common signals. Our pressure test gives a factual leak percentage before any sealant goes on. Call (806) 606-6902.
Can you repair ducts in Mission District without opening walls?
Most retrofit runs in Mission District flats are accessible from crawlspaces or closets, so yes, most repairs happen without cutting finished walls. We’ll tell you in writing if your specific run requires wall access.
Air Quality & Sanitizing in Mission District

Air quality and sanitizing in Mission District runs $280-$620 for a full-system treatment, with the written price based on the camera findings and square footage of the duct runs. The Mission’s damp nighttime air and retrofit ductwork create an environment where mold and bacteria establish inside the plenum and the first few feet of supply runs, and carbon soot from Mission Street and South Van Ness traffic deposits a sticky film that binds organic debris to duct walls. Our Air Quality & Sanitizing crews treat the full run and hand you a photo record documenting the inside before and after.
Mold Treatment
Signs you need it
Visible mold growth inside duct surfaces or a persistent musty odor that worsens when the system runs, both common in Mission District buildings with unventilated crawlspaces.
What it costs in Mission District
Mold treatment for a single-zone duct system runs $350-$550, depending on the affected area and run length.
How we do it
We apply an EPA-registered antimicrobial fog through the plenum and each supply run with the blower running, then scrub accessible surfaces and document the entire process with before-and-after photos.
Bacteria Sanitizing
Signs you need it
Recurring respiratory irritation, unexplained odors, or a previous moisture event in the ducts that introduced organic contamination.
What it costs in Mission District
Bacteria sanitizing runs $280-$420 for a standard Mission District flat with 6 to 10 supply runs.
How we do it
We use a hospital-grade sanitizer fog applied to all interior duct surfaces, dwelled according to label instructions, then run the system to distribute the treatment through every register.
Odor Removal
Signs you need it
A stale, smoky, or pet odor that returns whenever the HVAC blower cycles, indicating the smell has adhered to duct surfaces and insulation.
What it costs in Mission District
Odor removal runs $300-$500 for a full-system treatment, with the final number set by duct footage and odor source.
How we do it
We identify the odor source with the camera, clean affected surfaces with an appropriate extraction method, then apply an odor-neutralizing treatment and verify with a post-treatment airflow test.
UV Light Installation
Signs you need it
Recurring mold regrowth on the coil or plenum despite repeated cleaning, common where the Mission’s condensation cycle never fully dries interior components.
What it costs in Mission District
UV light installation runs $650-$900 per unit, including the fixture, bulb, and wiring by our licensed technicians.
How we do it
We mount the UV lamp at the coil or plenum location specified by your system’s layout, wire it to run continuously, and verify the coverage area before leaving.
Air Purifier Install
Signs you need it
Persistent allergy symptoms, heavy dust accumulation despite regular filter changes, or proximity to Mission Street and South Van Ness traffic corridors.
What it costs in Mission District
Air purifier installation runs $700-$1,200 depending on the unit size and duct configuration of your Mission District flat.
How we do it
We size the purifier to your square footage and airflow requirements, install it at the return plenum, replace the existing filter media with the manufacturer-recommended option, and walk you through maintenance.
What Air Quality & Sanitizing Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Mold treatment | $350-$550 |
| Bacteria sanitizing | $280-$420 |
| UV light installation | $650-$900 |
Will sanitizing damage my ducts in a Mission District flat?
No. We use EPA-registered treatments approved for galvanized metal and the flex duct materials found in Mission District retrofit systems. Your post-treatment photos document no surface degradation. Call (806) 606-6902.
Do I need mold treatment or just cleaning for Mission District ducts?
If the camera finds visible growth, mold treatment is the answer; cleaning alone won’t remove hyphae from porous surfaces. Our inspection gives you the images and a written recommendation without pressure.
