Air Duct Cleaning Company in Union City, CA
Air duct repair in Union City is a different job than it is in newer Bay Area suburbs. The 1950s through 1970s tract homes that dominate the Decoto and Alvarado districts still carry original galvanized trunk lines and early flex duct in attics and crawlspaces. After 50-plus years of marine air, temperature swings, and retrofit work, those ducts leak, separate at the joints, and shed debris into the air you breathe. We clean, repair, and protect ductwork with contractor-grade equipment, not a shop vac and a coupon. Call (855) 356-4417 for a straight answer about your system.
Why Union City Homes Are Different
Union City’s housing stock was built in a burst between the 1950s and 1970s, which means most single-family homes share the same bones: forced-air furnaces, rigid galvanized ducts with a joint every few feet, and floor registers original to the house. The Decoto district has even older pre-war homes where some ductwork predates modern sealing standards. The Alvarado neighborhood and the tracts around it were built fast and tight, with sheet-metal runs that have now spent half a century expanding and contracting through mild, damp winters and occasional summer heat spikes. That movement loosens joints. Loose joints pull dust from attics and crawlspaces into the airflow. Newer condos and townhomes near the BART corridor are a different story: many have flex duct retrofitted through tight ceiling spaces, and we find kinked or crushed runs that strangle airflow. The marine climate means systems don’t run as hard as they do in Livermore or Tracy, so debris accumulates slowly. Homeowners here often don’t call until they see dust on registers or smell something stale when the heat kicks on. By then, the ductwork has usually been leaking for years.

Our Main Union City Services
Most calls we take from Union City fall into two categories: homes with decades of buildup inside otherwise functional ducts, and homes where the ductwork itself is failing. Here’s how each job looks in this city.
Air Duct Cleaning in Union City
In Union City’s older homes, duct cleaning is rarely a quick vacuum pass. The original galvanized trunk lines in Decoto and Alvarado homes hold decades of dust, pet hair, construction debris from long-finished remodels, and occasionally pest droppings. We run Rotobrush rotary brush systems and Nikro HEPA-filtered extraction equipment through every run, agitating debris loose and pulling it out under negative pressure. That combination reaches what a consumer shop vac cannot. Homes with Aprilaire or Honeywell filtration systems get particular attention at the return side, where buildup chokes airflow. See the full breakdown on our Air Duct Cleaning in Union City page.
Dryer Vent Cleaning in Union City
Union City’s older homes often have long dryer vent runs that snake through crawlspaces or out under the roof overhang. Lint builds inside those runs, and in a home where the original 1960s vent was never replaced, that lint can compact against the galvanized walls and restrict airflow entirely. Your dryer vent is a fire hazard waiting to be ignored; we take it seriously. We clean the full run from the dryer transition to the exterior termination, and we flag any run that needs repair or replacement while we’re in there. Read the full scope on our Dryer Vent Cleaning in Union City page.
Air Duct Repair in Union City
In Union City’s older housing stock, Air Duct Repair is often more urgent than cleaning. Fifty-year-old galvanized ducts in the Decoto and Alvarado districts develop separated joints, rust-through spots, and crushed sections where decades of attic work took a toll. A leaky return pulls unfiltered attic air into your system; a leaky supply dumps conditioned air into the crawlspace. We test, seal, and replace what’s failed. For the full technical scope, see our Air Duct Repair hub page covering how we assess and fix damaged ductwork. Because Union City’s marine air keeps dust damp and heavy, debris in a failed duct section tends to cling rather than blow out, so we clean as part of any repair, not as an extra.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat setting, visible dust streaks around floor registers, or a musty smell from the vents when the system cycles on.
What it costs in Union City
Typical ductwork repair in Union City runs $350 to $800 depending on the number of failed joints, the material involved, and how accessible the duct is.
How we do it
We inspect the accessible run, identify each failed joint or damaged section, seal with aluminum tape and mastic as appropriate, and verify airflow after the repair.
Air Duct Replacement
Signs you need it
Duct work that collapses when touched, visible rust through the metal, or a full trunk line that has separated in more places than it holds together.
What it costs in Union City
Replacing a full duct system in Union City typically falls between $1,800 and $3,500 for a mid-century single-family home, depending on run lengths and attic access.
How we do it
We remove the failed sections or the full run, size the replacement to the furnace output, install sealed galvanized or flex duct as appropriate, and balance airflow at each register.
HVAC Duct Installation
Signs you need it
New furnace or heat pump installed on old ductwork, or rooms added to the house that were never properly ducted in the first place.
What it costs in Union City
New duct installation for a full system in Union City typically runs $2,500 to $4,000 depending on the home’s layout and the number of registers required.
How we do it
We lay out the supply and return runs according to the equipment’s CFM output, install properly sealed ducts at the correct diameter, and balance each register before we leave.

FAQs About Air Duct Cleaning Company in Union City
We schedule by route, not by emergency. Most Union City appointments get booked within a few days to a week depending on the season. Repair jobs that involve visible mold or pest debris get priority.
Most single-family homes in Union City aren’t HOA-governed for interior duct work. Condo and townhome associations near the BART corridor sometimes require notice before we access shared chase walls. We’ll ask about your HOA when you book.
Yes. Those homes make up the bulk of our Union City repair work. The original 1950s and 1960s floor registers and unlined galvanized trunks need careful handling, and we’re familiar with the exact patterns and common failure points in those districts.

What Union City Customers Say
"Told me straight that our ducts were in decent shape and didn't need doing every year like the mailer companies claim."
- Wade Doyle"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
- Elena Hernandez"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
