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 Union City, CA
Dryer vent cleaning in Union City is not a routine chore here; it’s a defense against lint packing into a clogged pipe and forcing your dryer to work twice as hard for half the result. The homes in Union City, many of them slab-foundation ranchers built in the 1960s and 1970s, often have long, hidden vent runs that collect debris faster than the short sidewall vents you find in newer construction. Add the persistent marsh humidity from the nearby Don Edwards refuge, and lint turns dense and sticky rather than loose and fluffy. If your clothes are taking two cycles to dry, call (806) 606-6902 and we’ll put a camera through the run to see what’s actually in there. We cover full Dryer Vent Cleaning with a documented photo record of every duct run we touch, before and after, so you can see the difference rather than take our word for it.
Why Union City Homes Are Different
Union City sits directly against the tidal marshlands of the Don Edwards San Francisco Bay National Wildlife Refuge, and that geography does not stay outside. The low-lying blocks west of I-880, particularly around the Alvarado neighborhood and the streets closest to the refuge, hold the marine layer longer than Fremont or Hayward. Ambient relative humidity stays high. Condensation forms on duct surfaces that would stay dry a few miles inland. The result, as we see it repeatedly, is dark mold colonies on the insides of duct plenums and registers in same-era homes that would show no such growth elsewhere in the East Bay.
Most of Union City’s housing was built between the late 1950s and early 1980s during the expansion of the former Decoto and Alvarado communities. That means a large share of homes still run original sheet-metal trunk lines or early fiberglass flex duct, now 40 to 60 years old. Duct-tape seams fail, flex sections collapse, and layers of debris pack into the low spots. When the dry heat surges push through the Niles Canyon corridor and humidity swings fast, those old joints and seals break down further. Air duct cleaning here is as much a moisture and mold-remediation job as it is a debris service. That is what we plan for when we quote a Union City job.
Our Main Union City Services
Two service lines dominate the calls we take from Union City homeowners: full air duct cleaning and HVAC system cleaning. Here is what each involves and why the local housing stock changes how we approach the work.
Air Duct Cleaning in Union City
Homes in the flatlands west of I-880, especially 1960s-era ranchers, carry original trunk lines that have collected everything from plaster dust to pet dander to mold spores for decades. We run Rotobrush negative-pressure extraction through every run, photograph the interior before and after, and hand you the record. No per-vent upselling, no bait-and-switch. Learn more about Air Duct Cleaning in Union City on its dedicated page, where the full pricing structure is laid out.
HVAC Cleaning in Union City
Union City’s humidity cycles put stress on evaporator coils, blower wheels, and drain pans in ways milder neighborhoods never experience. A clogged coil from a home near the wildlife refuge can cut airflow by 25 percent or more. Our HVAC cleaning addresses the full path from return grille to supply register, with photos of the coil before and after. See the full scope at HVAC Cleaning in Union City.

BeforeAfterDryer Vent Cleaning in Union City
The long vent runs common in Union City’s slab-foundation ranchers are a lint-trap waiting to happen. Many of these homes route the dryer vent through interior walls, up through the attic, and out a roof cap, which can be 15 to 25 feet of travel. Each bend is a collection point. When the marine layer holds humidity high, that lint turns matted and dense, and the airflow drops. Clothes take longer to dry, the motor runs hotter, and the risk of combustion inside the pipe rises. Our Dryer Vent Cleaning service uses professional Rotobrush equipment and a live camera feed, with before-and-after photos of the inside of your vent run delivered to you as part of the job record.
Dryer Vent Inspection
Signs you need it
Clothes stay damp after a normal cycle, the dryer exterior runs hot to the touch, or the flapper vent outside barely moves when the dryer is running.
What it costs in Union City
A standalone dryer vent inspection in Union City typically runs $89 to $149, depending on roof access and run length.
How we do it
We run a high-resolution push camera through the entire vent from the dryer connection to the exterior cap, marking every obstruction and measuring total run length.
Vent Cleaning
Signs you need it
The dryer shuts off mid-cycle on high-limit safety, or you can smell a burning-hair odor when it runs.
What it costs in Union City
Full dryer vent cleaning with before-and-after camera verification in Union City runs $129 to $229.
How we do it
We brush and vacuum the full run with a rotating nylon flail attached to a negative-pressure extraction unit, then photograph the interior at the dryer end and the cap end.
Lint Removal
Signs you need it
Visible lint is packed around the dryer connection point, or the exterior cap is visibly crusted with gray felt-like material.
What it costs in Union City
If the lint removal is a focused section-clear rather than a full-run clean, expect $79 to $129 in Union City.
How we do it
We extract the packed material at each access point, then verify clearance with the camera so you see the inside is clean, not just the first six inches.
What Dryer Vent Cleaning Costs in Union City
| Item | Typical range in Union City |
|---|---|
| Dryer vent inspection | $89 - $149 |
| Full dryer vent cleaning | $129 - $229 |
| Focused lint removal | $79 - $129 |
How long does dryer vent cleaning take in Union City?
Most Union City dryer vent jobs take 45 to 75 minutes. Longer roof-vent runs in Alvarado-area ranchers can push that to 90 minutes, but the price stays fixed at what we quoted before we started.
Do I need HOA approval for dryer vent work in Union City?
Most Union City HOAs do not require approval for cleaning an existing vent, but if we are installing a new roof cap or rerouting a run outdoors, your HOA’s architectural guidelines may apply. We can document the scope for your HOA file. Call (806) 606-6902 if you need a scope memo.
Duct Repair & Sealing in Union City
The 1960s and 1970s tract homes around Union City were built with sheet-metal trunk lines that are now half a century old, and many of the original seams were sealed with duct tape that has long since dried and failed. In the slab-foundation ranchers west of I-880, that means conditioned air bleeds into the subfloor and wall cavities, and return leaks pull dust and damp air from the crawlspace into the living space. Add the humidity cycles from the tidal marsh, and failing seals become mold pathways. Our Duct Repair & Sealing service addresses these failures with mastic sealant, flex replacement, and insulation, always with a written price before we start and a photo record of every repaired section.
Duct Sealing
Signs you need it
Rooms on the same floor differ by more than three degrees, or the furnace runs constantly without reaching the thermostat setpoint.
What it costs in Union City
Whole-house duct sealing in Union City ranges from $450 to $950 depending on accessible run count and leak surface.
How we do it
We locate leaks with a thermal camera and hand-pump pressure test, then hand-apply mesh-backed mastic to every leaking seam, collar, and plenum joint.
Flex Duct Repair
Signs you need it
Some rooms get almost no airflow while others blow hard, and the culprit is usually a collapsed or kinked flex section in an attic run.
What it costs in Union City
Replacing a collapsed flex duct section in Union City runs $180 to $420 per section, depending on diameter and attic access.
How we do it
We remove the failed section, install the proper diameter R-6 flex, tension it correctly, and band and mastic the connections at both collars.
What Duct Repair & Sealing Costs in Union City
| Item | Typical range in Union City |
|---|---|
| Whole-house duct sealing | $450 - $950 |
| Flex duct section replacement | $180 - $420 per section |
| Duct insulation wrap | $3 - $7 per linear foot |
Why are my Union City ducts leaking after every humid season?
The humidity swings between the tidal marsh air and the dry inland heat cause sheet-metal joints to expand and contract. Old tape seals crack under that stress. Our mastic sealing moves with the metal, which is why it holds in Union City’s conditions.
Can you seal only the accessible ducts and leave the attic alone?
We can, and we document exactly what was sealed and what was not, with photos. Partial sealing will not fix pressure imbalances, so we tell you that on the written estimate. Call (806) 606-6902 for the full picture of your system, because the attic runs are usually where Union City leaks happen.
Air Quality & Sanitizing in Union City
Homes on Union City’s west side, especially the streets closest to the Don Edwards refuge, present a specific problem: moisture that never really leaves. When ocean air pools in low-lying blocks during calm mornings, interior humidity climbs high enough to sustain mold on duct interiors, evaporator coils, and register grilles. The same organism that is absent in a Hayward hillside home can be thriving inside a Union City plenum. Our Air Quality & Sanitizing service treats the active growth, the source of the moisture if it is inside the duct system, and then applies a protective treatment registered for HVAC use, with photo documentation at every step.
Mold Treatment
Signs you need it
You see black or green speckling inside a register when you remove the cover, or the air from the vents smells musty even after the filter is changed.
What it costs in Union City
Focused mold treatment on a single plenum or coil area in Union City starts at $350 to $650.
How we do it
We photograph the affected area, remove surface growth with HEPA-vacuum and hand-cleaning, then apply a registered antimicrobial and document the after-condition.
Odor Removal
Signs you need it
A stale or burned-odor smell returns every time the system runs, even after a professional duct cleaning.
What it costs in Union City
Whole-system odor removal for a typical Union City rancher runs $250 to $450.
How we do it
We locate the odor source first (often a damp insulation section or a dead mouse in a return drop), remove it, and then fog the duct interior with a non-ozone deodorizer rated for occupied homes.
What Air Quality & Sanitizing Costs in Union City
| Item | Typical range in Union City |
|---|---|
| Mold treatment (single area) | $350 - $650 |
| Whole-system odor removal | $250 - $450 |
| UV light installation | $400 - $900 |
Will sanitizing my ducts get rid of the musty smell permanently in Union City?
Only if the moisture source is addressed. In Union City’s marsh-adjacent blocks, that often means sealing duct leaks that pull damp crawlspace air. We treat the growth first, then find and fix the water path. Call (806) 606-6902 for a written diagnosis.
How do I know mold in my ducts is actually gone after treatment?
We photograph the same section before and after. The photo record is part of the job file, not an add-on. If growth returns within 365 days, the 365-Day Done Right Promise covers re-treatment for the affected area.

FAQs About Air Duct Cleaning in Union City
Routine duct cleaning and sealing do not require a Union City permit. If we are replacing hard duct runs or altering the HVAC system’s physical footprint, that may fall under mechanical permit requirements. We handle the paperwork and tell you exactly what is required before any work begins.
In the marsh-adjacent blocks west of I-880, every 4 to 6 years is prudent because of the standing moisture. Homes on the drier east side of Mission Boulevard can typically go 6 to 8 years. A camera inspection tells you which side of that range applies to your house, for less than the cost of an unnecessary cleaning.
We schedule by appointment and give you a firm arrival window, typically two hours. Most Union City jobs are completed in three hours or less, and the written quote is delivered electronically before we arrive, so you do not need to stand by while the technician works. Call (806) 606-6902 to set a time that fits your week.
