AfterHow Much Does Air Duct Cleaning Cost in Sunnyvale?
Air Duct Cleaning in Sunnyvale typically runs $350 to $700 for a standard single-family home with one HVAC system, and most jobs land near $450. Homes with two systems, heavy contamination, or ductwork that needs repair push toward $900 or more. The price you’re quoted depends on the number of vents, the condition of the system, and whether we find damage that needs fixing alongside the cleaning.
We use Rotobrush rotary brush systems and Nikro HEPA vacuum units on every job, so the number you get reflects real extraction work, not a shop-vac pass-through. Free estimates are available if you want an exact figure for your home.
Key Takeaways
- Standard single-system homes in Sunnyvale: $350 to $700.
- Most homeowners pay around $450 for a thorough clean.
- Two-system homes and heavy-contamination jobs run $700 to $1,200.
- Duct repair, when needed, adds $200 to $800 depending on the damage.
- Dryer vent cleaning as a fire-safety service: $125 to $250.
- Every quote is based on an on-site inspection, not a phone guess.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what the line items look like for Sunnyvale homes this year. These ranges reflect what we see across jobs in the area, from older single-story homes near downtown to newer two-story builds out toward the Bay.

| Base duct cleaning (up to 10 vents, one system) | $350 – $450 |
| Additional vents beyond 10 | $15 – $25 each |
| Second HVAC system | $150 – $300 |
| Heavy contamination (rodent debris, mold, construction dust) | $200 – $500 add-on |
| Return and supply register cleaning | Included in base |

| Before/after inspection documentation | Included |
What moves your number up or down? The three biggest factors are vent count, system count, and condition. A twelve-vent single-story ranch home with routine dust sits at the low end. A two-story with two systems, flex duct that’s collected ten years of debris, and a return that’s pulled loose from the plenum pushes into the higher range. When we find damaged ductwork during the job, we repair it on the spot rather than leaving you to find a second contractor. We clean it. If it’s damaged, we repair it.
What Affects Air Duct Cleaning Pricing in Sunnyvale
- Number of vents and systems. A 1,400 sq ft single-story home in the Lakewood or Cherry Chase area typically has 8 to 12 vents and one system. A 2,400 sq ft two-story near Ponderosa Park often has 14 to 18 vents and two systems, which explains most of the price difference.
- Duct condition and access. Sunnyvale has a lot of homes built in the 1950s through 1970s. Some have original sheet-metal trunk lines that hold up well. Others have older flex runs that have sagged, torn, or pulled loose at the collar. Tight attic access or ducts buried under insulation adds labor time.
- Contamination level. We regularly see rodent activity in crawl spaces and attic runs, especially in homes backing up to Stevens Creek or the greenbelt corridors. Rodent debris, droppings, and nesting material require more extraction passes and HEPA work with Nikro equipment before the system is clean.
- Pollen and dust load. Santa Clara Valley’s spring pollen season runs heavy from March through May, and Sunnyvale homes pull a lot of it into return ducts. Homes with pets or recent remodeling see heavier buildup.
- Filters and IAQ setup. If your system has a Honeywell or Aprilaire filtration setup, we account for it during cleaning and can flag filter or media issues that are quietly raising your energy bill.
- Whether repair is needed. Loose joints, crushed sections, and disconnected returns are common findings. Repair pricing depends on how much ductwork has to be replaced and how accessible it is.
Why Professional Equipment Changes the Price (and the Result)
A $99 coupon and a $450 professional job are not the same service. Consumer shop vacs and compressed-air “tornado” tools stir up debris without capturing it, which can make indoor air worse before it gets better. Rotobrush rotary brush systems physically scrub the interior walls of each run, and Nikro HEPA vacuums hold the debris in a sealed filtration system so it leaves your home instead of settling in your living room.
Our focus is narrow by design. We handle three things: Air Duct Cleaning in Sunnyvale, dryer vent cleaning, and air duct repair. That’s it. No handyman list, no unrelated upsells. That focus shows up in how fast we diagnose problems and how clean the system actually is when we leave.
For system-level recommendations, we work with equipment from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. If your ducts are clean but your filtration is undersized or your return is pulling from a dirty garage, we’ll tell you. Air quality you can measure, not just feel.
How Much Does Dryer Vent Cleaning Cost in Sunnyvale?
Dryer vent cleaning in Sunnyvale runs $125 to $250, with most jobs around $175. That price covers full-line brushing, airflow verification, and removal of the lint load that builds up in the vent run.
We treat this as a fire-safety service, not an upsell. Lint is highly flammable, and a clogged vent is one of the most common causes of house fires. Sunnyvale’s older homes often have long exterior vent runs with multiple elbows, which trap lint faster than a straight run to the wall. If it’s been two or more years since your last cleaning, have it looked at. We usually schedule dryer vent cleaning alongside duct cleaning for a single visit.
How to Save on Air Duct Cleaning
- Bundle services. Scheduling duct cleaning and dryer vent cleaning in the same visit typically saves you the trip charge and some labor.
- Clean before peak season. Spring pollen (March through May) and summer AC season are the busiest months. Booking in late winter or early fall often gets you a faster appointment and a slightly better rate.
- Handle the prep. Clearing attic access and moving furniture away from vents saves technician time, and we pass that savings back.
- Keep up with filters. A clean filter and a proper filter change schedule slows dust buildup between cleanings, stretching the interval from every 3-5 years to longer.

When Duct Cleaning Isn’t the Full Fix
Cleaning a leaking system gets you a clean leaking system. If the inspection turns up disconnected joints, crushed runs, or torn flex duct, cleaning alone won’t solve the efficiency problem. That’s why we offer air duct repair in Sunnyvale as a companion service: sealing, patching, reconnecting, or replacing damaged sections so the system you paid to clean actually holds its pressure.
This matters most in Sunnyvale homes from the mid-century build era. Original ductwork that’s been through decades of attic heat and seismic settling is often loose at the collars. We document what we find with before-and-after inspection photos so you can see the condition, not just take our word for it.
Is Air Duct Cleaning Worth the Cost in Sunnyvale?
For most Sunnyvale homeowners, yes. Cleaning reduces dust load, eases allergies, and helps your HVAC run closer to spec. The U.S. EPA recommends cleaning when there’s visible contamination, rodent activity, mold, or a recent renovation, or when the system is significantly clogged. Outside those triggers, a cleaning every three to five years is a reasonable interval for most homes.
We’re a dedicated indoor-air specialist, not a generalist contractor. That means every technician we send works on ducting, dryer vents, and air quality all day, every day. If a company is cleaning ducts as a side line, ask what equipment they use. The answer will tell you a lot.

What Our Customers Say
"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."
- Javier Ramirez"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Leela Shah"They photographed every return and supply before starting and sent me the file afterward. No upsell to a sanitizing treatment I didn't need."
