Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable HVAC Cleaning Across Sunnyvale
HVAC cleaning in Sunnyvale means dealing with what’s actually inside a 1960s slab-ranch duct system, not running a generic vacuum through a register. Our crews work these attics every week. We know the flex-duct that crumbles at the first elbow, the sheet-metal trunk lines still carrying air after three furnace replacements, and the layers of foil tape and dried mastic that speak to decades of homeowner fixes. A full system cleaning here typically runs $425-$720 depending on duct count and access. Call (806) 606-6902 for a written price before anyone touches a panel.
Why CleanRun Air Duct Cleaning Is Sunnyvale’s Preferred HVAC Cleaning Company
We built our reputation in Sunnyvale on one thing: showing homeowners what’s inside their ducts before and after we work. A camera goes into every run. You see what we see. No fog, no vague reassurances.
Sunnyvale homeowners call us because the housing stock here demands a specific approach. The dominant home type is the 1960s-70s slab-foundation ranch, and its ducts run through attics that bake above 130°F all summer. That heat breaks down flex-duct inner liners and turns mastic brittle. A team that only knows negative-pressure extraction will leave half the problem behind. Our HVAC Cleaning crews use agitation tools and NADCA-standard source removal on every job, which is the difference between brushing debris loose and hoping the vacuum finds it.
Every job includes a Documented Photo Record of every duct run, before and after, delivered as part of the standard job record. That practice started with our first job in 2013 and has continued across 52,000+ homes served. Sunnyvale customers get a written price before work begins under Haven Standard Clause 1, and every technician is background-checked, uniformed, and identified by name before arriving.
Our HVAC Cleaning Services in Sunnyvale
Evaporator Coil Cleaning
Sunnyvale’s mild Mediterranean climate means your AC runs hard for maybe four months, then sits. Dust settles on the evaporator coil during the off-season and bakes into a damp mat the first time humidity spikes. A fouled coil raises static pressure and cuts cooling capacity. We pull the coil, document its condition with photos, clean it with professional-grade coil treatments, and show you the after image. A typical evaporator coil cleaning in Sunnyvale runs $240-$360 as part of a full system cleaning.
Blower Cleaning
The blower wheel in a Sunnyvale ranch often carries a decade of accumulated dust because it’s been ignored through multiple furnace swaps. A dirty blower moves less air per rotation, and that reduced airflow is exactly what causes coil freeze-ups on the hottest days. We remove the blower assembly, clean each blade, and photograph the wheel before reinstallation. Skipping this step while cleaning ducts is like changing the oil but leaving the old filter. Blower cleaning in Sunnyvale is typically $180-$260.
Condenser Cleaning
Outdoor condensers in Sunnyvale yards collect pollen from spring oaks, dust from summer dry spells, and cottonwood fluff from the creeks. A coil clogged with plant matter cannot reject heat, so the compressor runs hotter and longer. We clean the condenser fins with equipment from Rotobrush and Guardsman, clear the debris line, and check refrigerant pressures as part of the service. Condenser cleaning alone runs $150-$220 in Sunnyvale, less when bundled with a full system clean.
Air Handler Cleaning
Air handlers in Sunnyvale’s slab ranches sit in closets or garages, often next to the water heater, pulling in whatever the garage holds. The blower, the coil, the pan, and the cabinet interior all collect a film of dust and household aerosol. We disassemble the accessible sections, clean them with HEPA-filtered equipment, and document the inside of the cabinet. If the home still has original 1960s fiberglass duct board adjacent to the air handler, we flag it, because disturbing that material during cleaning without proper capture can send fibers into the supply air. Air handler cleaning in Sunnyvale typically runs $220-$340.

BeforeAfterTrusted Brands We Service in Sunnyvale
We service and clean systems from every major manufacturer found in Sunnyvale homes: Carrier, Trane, Lennox, Rheem, Goodman, and York, plus older brands like Day & Night and Westinghouse that still run in original 1960s installations. Our equipment roster includes Abatement Technologies for HEPA extraction and Nikro for negative-air and agitation applications, so the tools match the age and condition of your ducts. Because so many Sunnyvale homes have hybrid systems with mismatched components, we carry common adapters and flex-duct fittings on the truck, meaning less waiting on parts and fewer return trips.
Common HVAC Cleaning Problems We See in Sunnyvale Homes
- Degraded flex-duct inner liners in 130°F attics. The plastic liner inside flex duct dries out and collapses after decades of heat cycling, silently choking airflow to specific rooms. Camera inspection is the only way to find this without pulling registers and looking.
- Original 1960s fiberglass duct board that sheds fibers. Homes built during the Lockheed-era expansion often used rigid fiberglass duct board for branch runs. After 50+ years, the surface degrades and releases fibers during aggressive cleaning. Our methods capture those fibers at the source, not after they’ve entered living space.
- Layered mastic and foil-tape patches on trunk lines. Three generations of furnace work means three generations of sealing attempts. Old mastic cracks, foil tape peels, and debris collects in the gaps. We find this on nearly every Sunnyvale ranch we open.
- Wildfire smoke particulate driven deep into ducts. When AQI pushes above 150 during Northern California fire events, Sunnyvale residents seal windows and run fans continuously. PM2.5 smoke particulate gets pulled deep into the system in days, requiring source removal and not just filter replacement.

FAQs - HVAC Cleaning in Sunnyvale
Homes near Sunnyvale’s unpaved roads and open land - the edges of the city toward the bay or the foothills - load dust into ducts faster than paved suburban streets. For those properties, we recommend a full system cleaning every 2-3 years, compared to 3-5 years for a standard Sunnyvale tract home. The driver is fine particulate that settles in the plenum and branch runs during the mild months when the system cycles less. Call (806) 606-6902 and we’ll tell you what we charge for your square footage.
Yes, in a specific way. If a Sunnyvale property has a wood stove or shop heater in an outbuilding, the main house HVAC frequently pulls fine ash and creosote-laced dust through any shared crawlspace or attached garage access. That particulate is finer than typical household dust and works deeper into coil fins and blower blades. We recommend checking the return-air path from any attached outbuilding and cleaning the blower wheel and coil even if the ducts themselves look acceptable. Free estimates - call (806) 606-6902.
Because in a 50-year-old Sunnyvale duct system, the debris is adhered to surfaces, not lying loose. Mastic residue, compressed dust at elbows, and collapsed liner fragments will not move under negative pressure alone. Agitation tools - rotary brushes and air whips from brands like Nikro - break the mechanical bond so the HEPA negative-air unit can carry the material out. Negative pressure without agitation leaves decades of debris behind. That’s why our crews run both on every Sunnyvale job.
Clean first, every time. The cost of blower cleaning in Sunnyvale is $180-$260, and it protects the new motor from pulling the dust and debris that settled while the old one ran. We’ve opened systems in Lakewood and other older tracts where two furnace generations left the original sheet-metal trunk in place, with debris packed around the blower housing from both previous installs. Installing a clean motor into a dirty airstream shortens its life. Call (806) 606-6902 for a written price before you schedule the replacement.
Yes, they’re common, and no, cleaning alone cannot fix them. A collapsed inner liner means the flex duct’s plastic wall has separated from the insulation and folded inward, blocking airflow. Our camera inspection finds them routinely, especially on east-facing branch runs in homes built before 1980. Cleaning restores the rest of the system, but a collapsed liner needs replacement. We’ll show you the camera image, explain what we found in plain language, and quote a repair price in writing. For a camera inspection and written scope, call (806) 606-6902.
