Air Duct Cleaning in Sunnyvale - One Flat Price, Before-and-After Photos

Trusted Air Duct Cleaning for Sunnyvale Homeowners

Air ducts in Sunnyvale work harder than most people realize. Between the dry summer heat that bakes homes along El Camino Real and the bay humidity that rolls in through October, your HVAC system pulls a lot of air through those ducts. That air carries dust, pollen from the surrounding hills, and fine particulate that settles inside your ductwork over time. If you’re noticing dust on surfaces a day or two after cleaning, or rooms that never quite reach the temperature on your thermostat, you’re probably looking at restricted airflow from built-up debris. We clean what other companies walk past. Call (866) 593-7291 for a free estimate in Sunnyvale.

Key Takeaways

• Air duct cleaning in Sunnyvale typically costs $450 – $900 for a whole-home system based on home size and the number of vents.
• We use Rotobrush rotary brush systems and Nikro HEPA vacuum units, the same equipment commercial contractors rely on, not consumer-grade shop vacs.
• We clean it. If it’s damaged, we repair it. Duct Cleaning Sunnyvale handles air duct repair on the spot, closing the gap competitors leave when they find damaged ductwork but can’t fix it.
• Dryer vent cleaning is treatment as a fire-safety service, positioned alongside duct cleaning as an equally critical household maintenance task.
• One flat price per system agreed before work starts. No per-vent pricing surprises, and before-and-after photos of your own ducts so you can verify the work was done.

Air Duct Cleaning Services

Air Duct Cleaning Services involve removing accumulated dust, debris, allergens, and microbial growth from the full run of your HVAC ductwork, from the return registers through the main trunk lines to the supply vents in each room. Sunnyvale homes with pets, recent renovation work, or residents with allergy concerns typically need this every three to five years. Duct Cleaning Sunnyvale uses Rotobrush rotary brush extraction on every job, paired with Nikro HEPA-rated vacuum units that pull loosened debris out of the system rather than pushing it into your living space. See our Air Duct Cleaning cost guide for details; a whole-home air duct cleaning in Sunnyvale runs $450 – $900 depending on home size, number of systems, and the level of build-up.

Return and Supply Vent Extraction

We remove and clean every vent cover, then run our rotary brush through the full length of each duct line. The Nikro HEPA unit keeps negative pressure on the system the entire time, so what comes loose goes into the collection canister, not back into your bedrooms.

Plenum and Trunk Line Service

The main trunk lines carry most of your home’s air volume, and they’re where the heaviest debris settles. We access the plenum at the air handler and clean through each branch run so airflow to every room in your Sunnyvale home is restored.

HVAC Duct Cleaning

HVAC Duct Cleaning targets the entire forced-air system: supply and return ducts, the air handler cabinet, the blower fan, and the evaporator coil if accessible. This is the service to request when your system is running longer cycles than it used to, or when your energy bills have ticked upward without a change in usage. In Sunnyvale where summer AC and winter heat both get heavy use, a clean HVAC system runs measurably more efficiently. We quote a flat price upfront for our Air Duct Cleaning in Sunnyvale, between $450 and $900 for a typical Sunnyvale single-family home, so you know the full cost before we start. Our Nikro HEPA filtration captures what the brush dislodges, leaving your air handler and ductwork clean.

Air Handler and Blower Cleaning

The blower fan moves every cubic foot of air your family breathes. We open the air handler cabinet, clean the blower wheel and housing, and remove the dust that recirculates through your home even after a duct-only cleaning.

Coil and Drain Pan Servicing

A dust-coated evaporator coil insulates your cooling system from the air it needs to chill. We clean accessible coils and drain pans as part of our HVAC duct service, so your system cools properly and doesn’t pool condensation where mold can grow.

Vent Cleaning

Vent Cleaning focuses on the visible endpoints of your duct system: the supply registers in your floors, walls, or ceilings, and the return grilles that pull air back to the air handler. These are the parts you see, but they’re rarely the whole story. In Sunnyvale homes built in the 1960s and 1970s with original metal ducts, vent interiors often show rust, paint overspray, or even construction debris from decades-old remodels. We remove, clean, and reinstall every vent cover, then clean several inches into each vent boot where household dust collects fastest. Full vent cleaning as part of a whole-home service runs $450 – $900 based on home size and vent count.

Registration Cover Restoration

We clean rust, paint, and dust from vent covers using professional-grade cleaning agents safe for metal. If a cover is bent or broken, we can repair or replace it during the same visit instead of telling you to find a handyman.

Boot and Register Box Cleaning

The boot is the transition piece between the duct run and your floor or wall vent. It’s a right-angle trap for pet hair, dirt, and toys. Our rotary brush reaches into every boot to clear the bottleneck that reduces airflow to individual rooms.

Ductwork Cleaning

Ductwork Cleaning means cleaning the entire network of sheet metal or flexible duct that connects your furnace or air handler to each room. This is the real work of improving indoor air quality, because these hidden runs hold the dust you can’t see. We see a lot in Sunnyvale: flex ducts that have sagged and collected debris in low spots, metal ducts with interior rust from coastal moisture, and old systems that haven’t been opened since the Reagan administration. Our Rotobrush system scrubs the interior surfaces clean while the Nikro HEPA unit maintains negative pressure. Ductwork cleaning for a typical Sunnyvale home costs $450 – $900 depending on duct condition and house size.

Flex Duct and Metal Run Servicing

Flex duct requires a different brush tension than rigid metal. We adjust our equipment for the duct type in your home, whether that’s sheet metal in a 1960s Sunnyvale ranch or flexible runs in a newer north Sunnyvale build.

Duct Sealing and Repair Assessment

While we clean, we inspect for separated joints, tears, and crushed sections. If we find damaged ductwork, we can repair it during the same visit. You shouldn’t have to call a second company just because your ducts need more than cleaning.

Air Duct Inspection

Air Duct Inspection is a visual and diagnostic look inside your duct system before any cleaning begins. It’s what separates a responsible contractor from a company that just hooks up a vacuum and hopes for the best. In Sunnyvale, where homes range from 1950s Eichlers to new construction near Apple Park, duct systems vary wildly in age, material, and condition. An inspection identifies blockages, leaks, mold, pest activity, or previous shoddy work. We perform a standard inspection as part of every duct cleaning quote at no charge, and a full diagnostic inspection with camera equipment runs $150 – $350 when you need documentation for a home sale or landlord-tenant situation.

Pre-Cleaning Visual Assessment

Before any cleaning, we look at your registers, boots, returns, and accessible plenum to understand the layout and condition of your system. We also note any issues that will affect cleaning effectiveness, like disconnected runs or collapsed flex.

Documentation for Real Estate Transactions

When you’re buying or selling a home in Sunnyvale, an air duct inspection provides a written record of duct condition. We document what we find with photos and a clear written summary, useful for negotiations on older Sunnyvale properties.

Residential Air Duct Cleaning

Residential Air Duct Cleaning in Sunnyvale is our most common service, handling single-family homes, townhomes, and condos across neighborhoods from Raynor to Birdland. We understand the specific conditions local homes face: construction dust from ongoing South Bay development, pet dander from multi-dog households, and the fine particulate that drifts in from freeway traffic along 101 and 280. A standard residential cleaning runs $450 – $900, with the exact quote depending on home size, number of systems, and how long it’s been since the last service – see our Air Duct Cleaning Cost Breakdown: The Sunnyvale Homeowner’s Reference for 2026 for more details. We treat every Sunnyvale home as if our own family breathes its air, because the people who hired us do.

Single-Family Home Service

Most Sunnyvale single-family homes have one system and 10 to 20 vents. We quote one flat price per system so the number we give you before the job is the number on your invoice after. No surprise add-ons, no per-vent tally.

Townhome and Condo Duct Service

Condo and townhome systems are often smaller but shared with adjoining units, which means dust from one unit can migrate through the walls. We clean these systems thoroughly and check for any cross-unit leaks that should be sealed by an HOA contractor.

Commercial Air Duct Cleaning

Commercial Air Duct Cleaning serves Sunnyvale offices, retail spaces, restaurants, and light industrial facilities. Commercial systems run longer hours and move more air than residential systems, which means the build-up is different: more construction dust from tenant improvements, more human traffic debris, and sometimes more severe contamination from roof leaks or kitchen exhaust. We use our Rotobrush and Nikro HEPA equipment on every commercial job, the same standard required for remediation-level work. Commercial quotes are project-priced based on square footage and system complexity, but most Sunnyvale commercial duct cleaning projects fall between $900 and $2,500 for a standard office suite or retail space.

Office and Retail Space Service

We schedule commercial work around your business hours to minimize disruption, often early mornings or Sundays for Sunnyvale offices and retail. We provide documentation for building management or lease compliance when needed.

Restaurant and Light Industrial Facilities

These spaces face odor-trapping grease and heavier particulates. Our HEPA filtration air-cleaning approach keeps contaminated air from recirculating into occupied areas during the cleaning process, which matters in a food prep environment.

Brands We Service

We work with professional equipment brands including Rotobrush and Nikro, and we’re familiar with the air-quality systems from Aprilaire and Guardsman. When we encounter a home in Sunnyvale that has an Aprilaire whole-home filtration unit, we understand how that system integrates with ductwork and we adjust our process accordingly. Guardsman filtration components come up in newer Sunnyvale construction where developers spec a baseline filtration system, and we’re familiar with how those filters perform under real conditions.

Whether you have Rotobrush, Nikro, Aprilaire, Guardsman, or any other make of HVAC and filtration equipment, we can help. Our team sees these systems across Sunnyvale every week, and we know which ones perform well in our specific climate, with its dry inland heat and bay-side humidity swings.

Signs You Need a Pro Right Now

• Dust on every surface within days of cleaning. If you dust on Saturday and it’s back by Wednesday, your ducts are likely recirculating particulate rather than trapping it. The visible dust on your furniture is the same air your family breathes.
• Rooms that never reach the thermostat temperature. One bedroom freezing while the living room cooks means a duct restriction or imbalance. That’s often a blockage we can find and fix during a standard cleaning.
• Unexplained allergy symptoms at home that improve when you leave. Indoor air can carry more particulate than outdoor air when ducts are dirty. This is a common concern in Sunnyvale where residents spend so much time indoors during hot summer months.
• Visible dust or debris blowing from vents when the system cycles on. That’s not normal operation. It means built-up material is finally breaking loose and entering your living space. A cleaning now prevents bigger problems later.
• Musty or stale smell when the HVAC runs. Moisture in the ducts plus Sunnyvale’s seasonal humidity creates conditions for microbial growth. This is a signal to inspect and clean before it affects the whole system.

Our Process, Step by Step

1. 1
   System Inspection and Quote. We arrive, look at your system layout, check access points, and give you a flat price per system before anything starts. No per-vent tally, no hidden fees. You’ll know exactly what you’ll pay.
2. 2
   Equipment Setup and Protection. We lay down floor protection at every work area and connect our Nikro HEPA vacuum unit to the main duct line to establish continuous negative pressure. This keeps loosened debris from entering your rooms.
3. 3
   Rotary Brush Extraction. Our Rotobrush rotary brush system runs through every duct run, scrubbing interior surfaces clean. For flex duct we adjust brush tension for the material, so we don’t damage older, brittle ducts.
4. 4
   Air Handler and Component Cleaning. We clean the blower wheel, the air handler cabinet, and accessible coil and drain pan areas. A duct cleaning that skips the blower simply redirects dust back into the system within weeks.
5. 5
   Final Walkthrough and Documentation. We show you before and after photos of your own ducts so you can see what we removed and verify that the work was done. If we found damage during cleaning, we tell you and provide repair options on the spot.
