Air Duct Cleaning Company in Sunnyvale, CA
Air duct repair in Sunnyvale usually means sealing joints in 1950s-era metal ductwork or replacing crushed flex in newer townhome builds near Moffett Park. We’re Duct Cleaning Sunnyvale, and we’ve served Sunnyvale since 2015. The two most common calls are for cleaning systems that haven’t been touched in decades and for repairing duct runs that previous owners patched poorly. Call (866) 593-7291 if you suspect either problem, because a damaged duct system makes every cleaning you pay for a temporary fix.
Why Sunnyvale Homes Are Different
Sunnyvale’s housing stock splits into two very different duct situations. Downtown and the older neighborhoods south of El Camino Real are mostly low-slung 1950s and 60s ranches and Eichler-influenced homes. These have original rigid sheet-metal ducts running through attics, and after sixty or seventy winters, the mastic at the register boots is often cracked or missing entirely. The result is a system that pulls attic air, insulation fibers, and whatever else is up there directly into the living space.
The newer townhomes and condo infill around Peery Park and the tech campuses present the opposite problem: short flex-duct branches in tight interstitial spaces, often installed under deadline pressure during the last building boom. We see crushed or kinked flex, disconnected takeoffs, and returns that were never properly balanced. Sunnyvale’s mild Mediterranean climate means the HVAC system isn’t running constantly like in Tracy or Modesto, so problems develop slowly. Dust settles, rodents find their way in after atmospheric-river storms, and by the time a homeowner notices, the ducts have been circulating compromised air for months.

Our Main Sunnyvale Services
Most Sunnyvale homeowners call us for one of two services. Each has its own dedicated page with full pricing and local detail.
Air Duct Cleaning in Sunnyvale
Cleaning is the service that reveals what’s actually inside your ducts. In Sunnyvale, that’s typically decades of accumulated dust in older homes, or construction debris and drywall dust in newer builds. We run Rotobrush rotary brush extraction through every reachable run, paired with a Nikro HEPA vacuum pulling negative pressure the entire time. For the full breakdown of what cleaning covers in Sunnyvale and what it costs, see Air Duct Cleaning in Sunnyvale.

Dryer Vent Cleaning in Sunnyvale
Dryer vent cleaning is a fire-safety job, not a convenience. Lint accumulates in the vent run, and in Sunnyvale’s older homes that run can stretch twenty feet or more through an attic or crawlspace. A clogged vent forces your dryer to overheat, and lint is combustible. We treat this as seriously as any repair call. See Dryer Vent Cleaning in Sunnyvale for local specifics and pricing.

Air Duct Repair in Sunnyvale
Air duct repair in Sunnyvale typically involves resealing joints and replacing damaged sections in systems that are forty to seventy years old, especially in the ranch and Eichler-era homes around downtown and the older neighborhoods east of Wolfe Road. The dry summers and wet winters work on duct joints like a slow chisel; mastic dries and cracks, and atmospheric-river rain drives moisture into attics where it corrodes metal seams and gives rodents a warm reason to chew through flex. Many homes also come to us with prior handyman patches and mismatched flex connectors, particularly tech-heavy turnover properties near the campuses. When we clean a Sunnyvale system and find damage, we don’t hand you a report and leave. We fix it. The full scope of what repair covers is detailed on our Air Duct Repair page.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat setpoint, visible dust around register boots, and a utility bill that climbs without explanation are the three most consistent signs of leaking joints.
What it costs in Sunnyvale
Ductwork repair in Sunnyvale ranges from $250 to $1,400 depending on access and the number of joints needing resealing or sections needing patching.
How we do it
We locate the leaks with a pressure test or visual inspection, seal them with mastic or foil tape rated for HVAC use, and verify the repair with a second pressure reading.
Air Duct Replacement
Signs you need it
Crushed flex, rusted-through metal sections, or insulation that’s been shredded by rodents are signs that a patch won’t hold and the run needs replacing.
What it costs in Sunnyvale
Air duct replacement in Sunnyvale runs from $1,200 to $3,500 depending on the length of the run and whether we’re working in an accessible attic or a tight crawlspace.
How we do it
We remove the damaged section, install new rigid or flex duct sized to match the existing system, seal every joint, and re-balance airflow to the affected rooms.
Ductwork Installation
Signs you need it
New room additions, converted garages, or a full HVAC replacement often require new duct runs sized and routed correctly from the start.
What it costs in Sunnyvale
New ductwork installation in Sunnyvale falls between $1,800 and $5,000 depending on the number of runs, the duct type, and attic or crawlspace access.
How we do it
We calculate room-by-room airflow requirements, route the new ductwork along the most direct path that preserves attic access, and seal and insulate every joint.
What Air Duct Repair Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Ductwork repair (reseal joints, patch sections) | $250 – $1,400 |
| Air duct replacement (per run) | $1,200 – $3,500 |
| Ductwork installation (new runs) | $1,800 – $5,000 |
Prices move in Sunnyvale based mostly on attic access. Eichler-era roofs with low-slope pitch and minimal crawlspace clearance take longer to work in, and that’s reflected in the final number. You’ll always get one flat price per system, agreed before we start.
Can you repair ducts the same day you find a problem?
Yes. If we’re already in a Sunnyvale attic for a cleaning and find a separated joint or crushed flex, we repair it on the spot. We carry mastic, foil tape, flex duct, and rigid sections in the truck.
Do older Sunnyvale homes need full replacement or can they be repaired?
Most can be repaired. Original 1950s and 60s metal ductwork in Sunnyvale is often in better shape than expected. What fails is the mastic and tape at the joints. Resealing solves the majority of problems.
Brands We Service in Sunnyvale
We work on systems tied to Honeywell and Aprilaire air-quality equipment, and we stock filters and common replacement parts locally so we don’t have to order and reschedule. Turnaround on parts in Sunnyvale is usually one to two business days. Our full brand coverage is on the brands page.

FAQs About Air Duct Cleaning Company in Sunnyvale
Lead time is usually under a week for cleaning calls, and repair calls get priority because a disconnected duct is actively pulling attic air into the house. If you’ve got a section of flex hanging loose, call (866) 593-7291 and we’ll work you in sooner.
For single-family homes, no. Duct cleaning and repair inside your own system does not require a Sunnyvale building permit. For townhomes and condos, check your HOA’s rules on exterior vent terminations before scheduling dryer vent work, since some associations require licensed contractors or specific vent caps.
Yes. Many Eichler-influenced Sunnyvale homes have radiant floor heat and added a separate forced-air system later, often with ductwork that was never properly designed for the space. We inspect what’s there, identify what’s actually connected, and quote from what we find.

What Sunnyvale Customers Say
"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
- Jodi Parker"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."
- Claudia Martinez"My wife's allergies had been bad in this house since we moved in. It's been two months since they did the ducts and it's noticeably better. Not a miracle, but real."
