Air Duct Cleaning Company in Union City, CA
Air duct repair in Union City usually means one of two things: a failing flex run in a 1980s hillside attic, or a taped galvanized joint that finally let go in a 1950s crawlspace off Decoto Road. Duct Cleaning Mountain View has served Union City since 2015, and we see both jobs every month. The work here is split by ZIP code and housing era, and the fix usually starts with figuring out which Union City you live in. Call (866) 528-3938 if you already know you have a duct problem.
Why Union City Homes Are Different
Union City sits in the East Bay’s temperate marine band, where summer fog rolls in off the bay and HVAC systems run far less than they do ten miles inland. That sounds like good news for ducts, and it is, partly. Dust accumulates more slowly. But the same mild climate means attics and crawlspaces stay damp longer, and damp air is what rats and mice follow. In Union City we open more ducts for rodent debris and moisture damage than we do for heavy dust loading.
The housing stock splits along the Hayward border. In 94587, the older Decoto and Alvarado flats hold mostly pre-1960s single-story stucco homes on crawlspaces, many with original rigid galvanized ductwork. In the hills and east side of 94536, you get 1970s through 2000s tract subdivisions with flex duct in attics. A 1958 home off Alvarado-Niles Road and a 1997 home near Contempo Park are not the same job. Galvanized duct can be cleaned and resealed; 40-year-old flex often just needs replacement. We plan the work differently depending on which Union City we’re in.

Our Main Union City Services
Most Union City homeowners call us for one of two things: a full cleaning after they discover what’s been living in their ducts, or a dryer vent that’s become a slow, damp nuisance. Here’s what each looks like here.
Air Duct Cleaning in Union City
In Union City, air duct cleaning often starts with a simple question: what era is this house? In the Decoto flats, we’re cleaning galvanized runs that may have been in place for sixty years. In the hills, we’re cleaning flex duct that may have been installed in a weekend. Both need the same professional approach: Rotobrush and Nikro cleaning systems, Abatement Technologies HEPA containment so what comes off the duct walls doesn’t go back into your air, and a methodical pass through every supply and return register. For the full Union City cleaning picture, see Air Duct Cleaning in Union City.
Dryer Vent Cleaning in Union City
Union City’s older homes often have short dryer vent runs that exit through the crawlspace wall, which sounds convenient but means lint builds up where damp air makes it stick and harden. Hill homes tend to have longer, more convoluted runs up through attics. Either way, a clogged dryer vent here is a slow burn risk, not a metaphor. We clean the full run from dryer to termination point, and we inspect the connection while we’re there. For the specifics on how we handle Union City dryer vents, see Dryer Vent Cleaning in Union City.
Air Duct Repair in Union City
Air duct repair in Union City usually means finding a gap that’s been bleeding conditioned air into a crawlspace for years. In the pre-1960s homes of 94587, the culprit is often original galvanized duct with taped joints that dried out and separated decades ago. In 94536’s hill tract homes, it’s more likely sagging or crushed flex duct in the attic, sometimes chewed open by rodents. Either way, cleaning alone doesn’t fix a broken duct. We clean the duct, and we fix it if it’s broken. Our repair work is its own service line, not an add-on: full Air Duct Repair, from a single joint reseal to a full attic re-duct.
Air Duct Replacement
Signs you need it
Flex duct that’s crushed, torn, saturated, or rodent-chewed usually should be replaced, not patched, especially in older Union City homes where the insulation jacket has degraded.
What it costs in Union City
Air duct replacement in Union City typically runs $2,500 to $7,000 depending on the number of runs, the access situation, and whether the home has one return or several.
How we do it
We remove the failed duct, size the replacement to the room’s airflow needs rather than just matching what was there, install new insulated flex or rigid duct as the application requires, and seal and support every connection.
Ductwork Repair
Signs you need it
Rooms that never reach temperature, whistling near registers, visible gaps in exposed duct, or a crawlspace that smells like whatever’s being pushed through the system.
What it costs in Union City
Targeted ductwork repair in Union City, such as resealing a run of joints or replacing a single failed section, typically falls between $300 and $1,200 per affected run depending on access.
How we do it
We locate every separation with a visual inspection plus pressure testing when needed, then reseal joints with mastic and reinforced tape, re-support sagging sections, and confirm airflow before we leave.
What Air Duct Repair Costs in Union City
| Item | Typical range in Union City |
|---|---|
| Joint resealing, single run | $300 – $600 |
| Duct section replacement, one supply run | $600 – $1,200 |
| Full flex replacement, average 3BR home | $2,500 – $7,000 |
What pushes price up in Union City is crawlspace access in the older flats, where clearance can be tight and runs snake through tight wall chases. The hillside attics of 94536 tend to be easier to move around in, but longer runs and steeper rooflines add complexity on their own. You’ll get one flat price per system before any work starts.
Can you repair ducts in a crawlspace without tearing out walls?
Yes, in most Union City crawlspaces we can reach and reseal or replace duct without opening walls. Pre-1960s homes can have chases we need to open, but that’s the exception. We’ll tell you before we start if wall access is likely.
Should I replace my galvanized ducts or just seal them?
If the metal is sound and the joints are the problem, sealing is usually enough. Galvanized duct from the 1950s can be serviceable for decades. If rust, collapsed sections, or persistent rodent damage are present, replacement makes more sense. We’ll show you what we find. Call (866) 528-3938.

In Union City, the biggest price variable is access: crawlspace work in the Decoto flats tends to run higher than attic work in the hill tracts, and two-story homes add ladder and lift time. Whatever the job, we quote one flat price per system before work starts, not a per-vent estimate that changes once we arrive.

What Union City Customers Say
"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
- Christine Yang"Job was done well and the house smells better. There was some dust knocked loose around a couple of the registers that I had to wipe down afterward."
- Dale Thompson"They photographed every return and supply before starting and sent me the file afterward. No upsell to a sanitizing treatment I didn't need."
