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.

Most Sunnyvale homes were built between the 1950s and 1970s, and many have their dryer vented through a long horizontal run to a side-wall or roof jack. That means lint accumulates along the full length of the duct rather than just at the trap. The run length and number of elbows, not the age of the dryer, usually determine how much lint has built up. We know these houses. We know where the lint hides.
Why Cardinal Air Duct Cleaning Is Sunnyvale’s Preferred Dryer Vent Cleaning Company
We earn our place on Sunnyvale’s short list by doing the job the way a homeowner would do it if they had a Rotobrush and a Nikro HEPA vacuum: thoroughly, honestly, and with proof. Our Dryer Vent Cleaning team cleans the full duct run from the dryer transition to the exterior vent hood, not just the first few feet behind the appliance. When we finish, you get before-and-after photos of your own ducts. Not stock images. Not a receipt that says “done.” Actual pictures from inside the vent line.
Sunnyvale homeowners call us because our price doesn’t shift once the technician is inside. A written price is handed to you before a single duct is touched, and it does not change at the door. If you live in a 1960s rancher off Remington Drive with a roof-terminated vent, the quote accounts for that run from the start. Omar Haddad leads our team with a simple rule: if the work isn’t right within 365 days, we return and correct it at no charge. That’s the 365-Day Done Right Promise, and it covers every job without exception.
Dryer Vent Cleaning Company in Sunnyvale
Cardinal Air Duct Cleaning is a Dryer Vent Cleaning Company serving Sunnyvale that operates on a flat rate per dryer vent system, not per vent. A full cleaning for a typical Sunnyvale single-family home runs $169 – $329, and that price is written down and handed to you before work starts. No per-vent math. No phone quote that grows once the technician sees a 25-foot run with three elbows. What the job involves here: we disconnect the dryer, run agitation tools through the full duct length to break up the lint cake, then pull everything out with a Nikro HEPA-filtered vacuum using negative-pressure extraction.
Negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your laundry room. For Sunnyvale homes with roof jacks, we work from the roof down or from the dryer outward, depending on access, and we do not leave roof flashing loose or damaged. When a dryer vent run passes through a hot attic, we inspect the full length for disconnected joints or crushed sections, because those are the failure points that let lint dump into the attic cavity.
What the Equipment Handles
We run Rotobrush rotary systems for agitation and Nikro HEPA vacuums for extraction. The difference between this setup and a big-box truck-mounted shop vac is simply how much lint actually leaves the vent. A standard shop vac loses suction over a 20-foot run. Our equipment is built for the length. For homes near the Civic Center area with narrower side yards and tight vent access, we bring the same full kit, just staged more compactly.
Transition Duct Replacement
The flexible foil or plastic transition duct behind the dryer is the most common weak point in older Sunnyvale homes. It kinks, crushes, or fills with lint faster than the rigid metal ducting in the wall. When we clean a vent, we check the transition and replace it with rigid metal if it’s collapsed. That replacement is included in the flat price, not added as a line item after the fact.
Dryer Vent Inspection in Sunnyvale
A Dryer Vent Inspection in Sunnyvale runs $89 – $129 on its own and is included at no extra charge with every full cleaning. We run a camera down the entire duct run and show you the footage. If you’re buying a home in the Lakewood Village area or selling one near Cherry Chase, this is the documentation you want: proof the vent is clear, connected, and terminating correctly. If the inspection uncovers a problem, like a disconnected duct in the wall cavity or a crushed section under the house, you get a written quote for the repair before anything is done.
Sunnyvale’s mid-century homes frequently have vent runs that were installed before current building codes required rigid metal. We see foil tape failing at joints, flexible plastic ducting that should have been replaced decades ago, and vent hoods with flappers that no longer seal. An inspection is not just a camera pass. It includes checking airflow at the exterior termination, verifying the flapper opens and closes, and measuring how much lint has accumulated along the run.
When an Inspection Catches a Fire Hazard
Lint is combustible. When a roof-terminated vent in a warm Sunnyvale attic has a disconnected joint, lint escapes silently into the insulation, where it sits against hot surfaces all summer. That’s the scenario an inspection is designed to find before the dryer does. We show you the camera footage, explain exactly what’s wrong, and give you a flat quote to correct it.
For Real Estate Transactions
If a home inspector flagged the dryer vent on a Sunnyvale property you’re buying or selling, we can complete a cleaning and inspection within the escrow timeline in most cases. Reports include the camera footage and a summary of any deficiencies. We’ve worked with homeowners from Heritage District to Birdland who needed a vent cleared and documented before closing.
Trusted Brands We Service in Sunnyvale
We work on dryers and vent systems from every major brand, and we stock common replacement parts for Sunnyvale’s older housing stock: vent hoods, rigid metal ducts, transition sections, flappers, and roof jacks. Our Sunnyvale HVAC Cleaning crews use the same equipment standards on every job. Our technicians carry Rotobrush rotary brush systems and Nikro HEPA-filtered vacuums on every truck, plus Abatement Technologies containment units for jobs where loose lint would otherwise spread through a finished laundry room. Whether your dryer is an LG stacked unit in a condo near downtown or a 1990s Kenmore in a Ponderosa Park rancher, the vent gets the same full-length cleaning.
Common Dryer Vent Cleaning Problems We See in Sunnyvale Homes
- Long horizontal runs in 1950s – 1970s ranchers. Many Sunnyvale homes off El Camino Real and Wolfe Road have dryer vents that travel 15 – 25 feet to a side wall. Lint builds in layers along the entire run, not only at the trap. A cleaning that only handles the first five feet leaves most of the problem untouched.
- Roof-terminated vents through hot attics. Homes near Raynor Park and farther south often vent through the roof, where attic heat bakes the lint into a hard, dense layer. These runs need agitation tools to break the lint cake before vacuum extraction can pull it out.
- Crushed flexible transition ducts behind the dryer. The tight laundry closets common in Sunnyvale’s older townhomes and in-law units often crush the foil transition behind the machine. A kinked transition reduces airflow even before lint becomes the main issue. We replace these with rigid metal as part of standard service.
- Failed flappers and bird-damaged vent hoods. A vent hood flapper that no longer seals lets outside air, dust, and birds into the duct. Homes in the Sunset and Ortega Park neighborhoods with ground-level or crawlspace-adjacent terminations report this most often. We carry replacement hoods, flappers, and bird guards on every truck.
Pricing for Dryer Vent Cleaning in Sunnyvale, CA
A standard whole-system dryer vent cleaning in Sunnyvale runs $169 – $329.

A short, straight side-wall run in a condo near the Sunnyvale – Mountain View border sits at the lower end. A 25-foot roof-terminated run with a crushed transition in a 1960s rancher near Braly Park sits at the higher end.

FAQs About Dryer Vent Cleaning in Sunnyvale
Yes, and we account for it in the flat price. Roof-terminated runs are common in Sunnyvale’s 1950s – 1970s housing stock, especially near Serra Park and Cumberland South. These runs collect lint differently because attic heat hardens it, and the vertical section requires agitation tools to break up the plug before vacuum extraction. We clean from the roof down or from the dryer up, depending on access, and we check the roof jack and flashing for damage. The price for a roof-terminated run is higher than a short side-wall run, but it’s written down and agreed to before we start. Call (737) 727-2314 and tell us where your vent terminates – we’ll give you a firm number over the phone.
Every 12 to 18 months for most Sunnyvale homes, and every 12 months if your vent has a long horizontal run or terminates through the roof. Dryers in households with pets, large families, or heavy laundry use accumulate lint faster. Homes in neighborhoods like Gavello Glen with older vent runs and multiple elbows tend to clog more quickly than newer builds with short, straight ducts. The simplest test: if a load that used to dry in 45 minutes now takes 75, the vent is probably the reason, not the dryer. We’ll clean what’s there and show you the before-and-after photos so you know how much was actually removed.
Flat rate for the whole system. One dryer, one vent run, one price. We do not charge per vent, per elbow, or per foot. A typical Sunnyvale home pays $169 – $329 total, written down before work begins. Per-vent pricing is a bait-and-switch mechanism in this industry: a low phone quote becomes a much larger invoice once the crew sees a roof termination or a long horizontal run. We quote the job as a whole after asking about your home’s configuration, and that number does not change at the door.
A full camera pass through the entire duct run, from the dryer transition to the exterior termination, plus an airflow check at the vent hood, flapper operation verification, and a visual check for disconnected or crushed sections. You see the footage. If you’re in a Sunnyvale home with the vent running through an attic or crawlspace, we inspect those sections specifically for lint leaks or failed joints. A standalone inspection runs $89 – $129, and it’s included free with every full cleaning. If we find a problem, you get a written repair quote before any additional work is approved.
In most cases we can schedule within 1 – 3 business days for Sunnyvale appointments, and we do not overbook. A live person answers the phone 24/7 at (737) 727-2314, and we’ll tell you the next available window. Dryer vent cleaning is a scheduled job, and we don’t rush it. You’ll get a trackable arrival time through The Relay Standard booking experience, a written price before work starts, and before-and-after photos of your ducts. If you have a genuinely urgent issue, like a fully blocked vent that’s stopped your dryer from working, tell us on the call and we’ll do what we can to fit you in sooner.
