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 Air Duct Cleaning Across Sunnyvale
Air duct cleaning in Sunnyvale typically runs $450-$850 for a whole-home residential system, with most jobs completed in a single morning or afternoon. Our crews work the full stretch of Sunnyvale, from the Lockheed-era ranches near Raynor Park to the newer townhome clusters off Tasman Drive, and we coordinate dispatch from our San Francisco Bay Area office so we’re never far from your neighborhood.
We’ve been in enough Sunnyvale living rooms to know the routine: kids on the floor with tablets, a dog curled in the corner, someone trying to nap down the hall. That’s why our technicians wear shoe covers before they step past the threshold, lay drop cloths under every work zone, and keep the Rotobrush units at lower RPM when we know a toddler’s sleep schedule is on the line. We give you a written price before we touch anything, and we take a photo of the clean-up before we leave so you can see the difference, not just hear about it.

Why Morton’s Air Duct Cleaning Is Sunnyvale’s Preferred Air Duct Cleaning Company
Sunnyvale homeowners know their houses. They know the 1962 ranch on Glenview Drive still has the original attic ladder, and they know the new construction off El Camino Real was finished six months ago but the vents keep puffing drywall dust. We’ve earned our reputation here by matching that local knowledge with specifics, not generic talk.
Our reviews from Sunnyvale customers consistently mention the same things: the technician who noticed the cat’s water bowl and moved it before setting up, the written quote that matched the final invoice to the dollar, the photo proof of clean ducts sent before the crew packed up. We’re not guessing at what Sunnyvale families want; we’ve been listening since 2005.
Response time matters when wildfire smoke is pushing AQI past 150 and you’re running recirculated air through ducts that haven’t been opened in decades. Our Bay Area dispatch gets crews to Sunnyvale properties on scheduled appointments with windows we actually keep, not four-hour guesses. And we know the local housing stock cold: the slab foundations, the attic-mounted systems, the brittle fiberglass duct board that turns a routine cleaning into something more urgent.
Every visit carries the Cedarwell Care Promise and our 365-Day Done Right Promise. If it’s not right, we make it right. Full stop.
Air Duct Inspection in Sunnyvale
Air Duct Inspection in Sunnyvale is where we start every job, because Sunnyvale’s housing stock demands it. We run a video scope through your supply and return lines to map debris loads, check for delaminated fiberglass duct board in the attic trunks, and look for construction debris in newer builds before we quote any cleaning work. A typical inspection runs $150-$250, and if you proceed with cleaning, we roll that into your project price.
What We Look For in Older Ranch Homes
In the Lockheed-era neighborhoods, we’re hunting for brittle fiberglass duct board that’s started to shed glass fibers into the airstream. Attic temperatures in Sunnyvale can hit 140°F in July, and fifty years of that heat cooks the adhesive right off the original lining. We document it with the video camera so you see exactly what we see.
New Construction Checks
Builders in Sunnyvale’s newer developments often leave drywall dust, joint compound crumbs, and wood shavings in the duct runs. The HVAC contractor fired the system for the first time and blew some of it out, but plenty sticks to the damp metal. We flag it before your first allergy season.
Residential Air Duct Cleaning in Sunnyvale
Residential Air Duct Cleaning in Sunnyvale means matching the method to the house vintage, not running the same protocol everywhere. For a typical single-story ranch with attic ducts, we use negative pressure from a Nikro portable HEPA collector combined with Rotobrush agitation tools to dislodge debris from the supply and return lines, then seal any exposed fiberglass with mastic before we close up. A full system clean in Sunnyvale runs $450-$850 depending on duct length, access difficulty, and whether we need to address delaminated board. We do not price per vent. One flat price per system, agreed in writing before we start.
Protecting Your Home During the Work
We lay drop cloths from the front door to every register location, wear shoe covers inside, and use corner guards where hoses bend through doorframes. If your dog’s crate is in the hallway, we work around it. If nap time is 1:00 PM, we throttle the equipment down or pause.
What “Clean” Actually Looks Like
After agitation and extraction, we run the video scope again so you see the before and after in your own ducts, not stock footage. Then we photograph the clean-up: floors wiped, furniture back in place, drop cloths folded. You get that photo before we leave.
Trusted Brands We Service in Sunnyvale
Our trucks carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, not rental-shop vacuums with duct-tape adapters. The Rotobrush system we use for residential agitation in Sunnyvale’s ranch homes has adjustable torque for brittle fiberglass environments, and our Nikro HEPA collectors are rated for the fine PM2.5 ash we pull out after smoke events. We stock common Guardsman sealing products and Honeywell media filters so we can replace your clogged filter on the spot rather than sending you to a hardware store. For Sunnyvale homeowners, that means one visit, one crew, one completion.
Common Air Duct Cleaning Problems We See in Sunnyvale Homes
- Delaminated fiberglass duct board in Lockheed-era ranches. The original 1960s-70s tract homes near Ponderosa Park and Birdland neighborhoods still run attic duct systems with fiberglass board that’s turned brittle and friable. Heat cycling has destroyed the adhesive. A standard vacuum job misses it; we inspect, document, and seal or recommend replacement.
- Construction debris in new Sunnyvale builds. Townhomes and condos off Mathilda Avenue and near Lawrence Expressway often have drywall dust, joint compound, and wood shavings left in the ductwork from rough construction. The first homeowner runs the system and spreads it through every room.
- Wildfire smoke ash saturation. When AQI spikes and Sunnyvale residents seal windows for days, recirculated HVAC air deposits fine combustion particles deep in the return ducts and coats the evaporator coil. Standard filter changes don’t reach it.
- Shared-duct contamination in multi-family buildings. Apartment complexes built for the tech workforce near Central Expressway have rooftop units feeding multiple units through common trunks. Cross-contamination between units is common; we isolate and clean with negative pressure to prevent blowback.

FAQs About Air Duct Cleaning in Sunnyvale
Yes, and more often than new homeowners expect. Builders in Sunnyvale’s recent developments frequently leave drywall dust, joint compound crumbs, and wood shavings in the supply and return ducts after rough construction. The HVAC contractor’s initial system test blows some out, but fine particles adhere to the metal and get distributed through your home on the first real heating or cooling cycle. We inspect new builds regularly and find debris loads that surprise the owners. Call (323) 918-4345 for a free inspection.
These houses were built fast for Lockheed and early semiconductor workers in the 1950s-1970s, with original fiberglass duct board in the attic that was never designed to last fifty years. Sunnyvale’s attic heat, regularly exceeding 130-140°F in summer, cooks the adhesive until the fiberglass lining delaminates and sheds directly into the airstream. It’s a failure mode specific to this vintage and this climate. Our inspection catches it before a cleaning spreads fibers through every room. Call (323) 918-4345 to check your system.
Smoke events push PM2.5 particles through every gap in your home’s envelope, and when you seal windows and run recirculated HVAC air for days, those particles load your filter and coat the duct interiors. Standard filter changes don’t remove ash from the trunk lines or the evaporator coil. After major smoke events like the SCU Lightning Complex fires, we’ve extracted thick mats of fine ash from Sunnyvale ducts that the homeowners didn’t know were there. A full system clean with HEPA extraction is the only way to reset it. Call (323) 918-4345 to schedule.
We recommend MERV 13 or higher for Sunnyvale homes during and after wildfire smoke events, provided your HVAC system can handle the airflow restriction. MERV 13 captures at least 90% of PM2.5 particles. Check your system’s specifications first; some older units in the Lockheed-era ranches struggle with the static pressure. We stock Honeywell and Aprilaire media filters and can assess your system’s capacity during our visit. Call (323) 918-4345 and we’ll match the filter to your equipment.
We do, and we recommend bundling the two. Dryer vents in Sunnyvale accumulate lint faster than many homeowners realize, especially in homes where the dryer runs multiple loads daily for families with kids. A blocked vent is a genuine fire risk, and the same crew with the same HEPA equipment can clean it properly while we’re already set up for your ductwork. Bundled pricing runs $120-$180. Call (323) 918-4345 to add it to your appointment.
