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.

Call (737) 727-2314 any time; a live person answers and you’ll have a written price before we schedule.
Why Cardinal Air Duct Cleaning Is Mountain View’s Preferred Air Duct Cleaning Company
Part of the Relay Home Co. family founded in 2005, Cardinal operates on a standard most Mountain View homeowners tell us they’ve never experienced: total visibility. Every booking includes a live trackable arrival window, before-and-after photos of your own ducts, and a digital invoice you can pay from your phone. The price you’re handed before work starts is the price you pay. No per-vent math, no last-minute “discovery” charges.
Our technicians are background-checked, uniformed, and you know their name before you open the door. They’re running professional-grade equipment from Rotobrush for agitation and Nikro for HEPA-rated extraction, not a shop-vac taped to a truck. And this matters in Mountain View, where homes on the same block can have entirely different duct situations. Our lead tech Omar Haddad has walked systems from the 1950s slab-heated Eichlers north of El Camino to the newest attached units downtown. That range is exactly why we start with a camera inspection.
The 365-Day Done Right Promise backs every job we do in Mountain View. If the work isn’t right within a full year, we come back and make it right. That’s not a sales line; that’s the Relay Standard.
Air Duct Repair in Mountain View
Air duct repair in Mountain View usually means fixing what the original builders left behind: separated boots at the air handler, sagging flex runs in tight attics, or collapsed sections where a 1960s-era trunk line has finally given out under decades of thermal cycling. We don’t sell repairs you don’t need; we show you the camera footage first. A separated boot lets conditioned air dump into the wall cavity or crawlspace, so your register never gets the pressure it should, and your blower motor works harder than its static pressure spec.
When a Bay Area Home Needs It
The climate here plays a role. Mountain View’s dry summers and mild winters mean many homes shut their HVAC for months at a time. When rubberized flex duct sits unused through the heat, it dries. When it’s run through uninsulated attics that hit 120°F in July, its plastic liner stiffens. A small tear that began as a pinhole becomes a full separation. We test with a camera before recommending anything.
Repair Scope and Cost
A straightforward repair to a single branch run or boot connection in Mountain View typically runs $250 – $500. If it’s a full trunk line replacement or multiple return repairs, the range is wider and the flat price is calculated after the inspection, not before. The price includes the written guarantee on every repair, with a free second visit if the repair fails.
Ductwork Cleaning in Mountain View
Ductwork cleaning in Mountain View, done correctly, means more than a hose in a register. It means negative-pressure extraction: a HEPA-rated vacuum pulls continuously while agitation tools work the branch runs, so everything that comes loose goes directly into the filter, never back into your living room. The specific equipment matters here because of what’s actually in your ducts. In the older neighborhoods around Los Altos and Escuela, we often find fine dust that’s been accumulating since the Reagan administration, packed against the duct wall where a simple vacuum pass won’t reach it.
Why Original Duct Runs Behave Differently
The 1950s and 1960s homes across Mountain View’s flatlands were built for radiant-floor heating, with forced air often retrofitted later. That means your duct runs may be above the slab, partially in the slab, or stuffed into a tight closet. Not all of them are even accessible. We confirm what you have before we give a price, because a duct you can’t put a camera in is a duct we can’t honestly quote. Our process never skips that inspection.
Full System Cleaning
A full system cleaning in Mountain View runs $450 – $750 for a typical home, depending on the number of branch runs and accessibility. We clean the supply and return sides together because your system is one loop; cleaning half of it just re-contaminates the other half faster. The process typically takes three to five hours, with a written price handed to you before anything begins, and before-and-after photos emailed to you when the work is done.
Trusted Brands We Service in Mountain View
Our work takes us into every major system type found in Mountain View, and we stock parts and filters for the brands we see most often in local homes. We run Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for extraction, and Abatement Technologies containment units when the job involves separating a work area from living space. For filtration, we carry Honeywell and Aprilaire media filters and Guardsman products. Whatever your system, our team has the tools and the familiarity with these brands to do the work right.
Common Air Duct Cleaning Problems We See in Mountain View Homes
- Eichler-era duct runs that no one has touched since installation. In Monta Loma and Fairview Park, original attic duct runs from homes built between 1956 and 1968 often still carry their original registers. Debris packs at the boots and the air handler, and without a camera inspection you’d never know it.
- Tight air handler closets in newer infill. The newer attached units near Downtown and San Antonio have air handlers stuffed into a closet or garage ceiling. Get a cheap service out and they’ll quote by the vent, then realize halfway through they can’t actually reach half the runs. We inspect first.
- Blower motors pulling harder than they should. In the Monta Loma neighborhood, a 1961 ranch we cleaned had a blower motor pulling far above its static pressure spec from years of packed lint. After cleaning both the supply and return ducts, the static pressure moved back toward spec, and the homeowner noticed the air at the register immediately.
- Dry flex ducts cracking in the attic. Mountain View’s summer attic heat can reach 120°F. Over years, that bakes the plastic liner of flex duct until it cracks and separates. A repair usually follows a cleaning once the camera reveals the problem. Ask us to show you the footage before you agree to anything.

FAQs About Air Duct Cleaning in Mountain View
Most Mountain View homes need full duct cleaning every three to five years. If you have pets, run your HVAC year-round, or just completed a renovation, it may be closer to every two to three. If your home is newer and you’ve been diligent about filter changes, you might be able to stretch it to every five to seven. There’s no one-size answer for a city with this mix of housing stock. If you’re unsure, call (737) 727-2314 and we’ll help you decide based on what your inspection shows.
One flat price per system, always. Most Mountain View homes run $450 – $750 for a full standard cleaning. We don’t have a per-vent price sheet because that’s how the bait-and-switch contractors operate in this area: a low per-vent price draws you in, then the “discovery” charges start. We hand you a written price before any work begins and it doesn’t change at the door. For an exact quote, call (737) 727-2314.
Yes. Every booking includes before-and-after photos of your own ducts, taken during the camera inspection and again after the cleaning. You’ll see exactly what came out and what your ducts look like now. This is part of the Relay Standard, and it’s how we prove the work was actually done. If a company won’t show you your own ducts, ask yourself why.
First, a camera inspection to confirm what ductwork exists and its condition. Then we set up negative pressure with a HEPA-rated vacuum, run agitation tools through the branch runs to loosen debris, and clean both supply and return sides. The debris goes into the vacuum, not back into your home. Finally, we reseal any boots or connections if needed and show you the before-and-after photos. The whole process typically takes three to five hours depending on the size of the system and how accessible the ducts are.
We don’t promise same-day service because in Mountain View, a job done right often requires an inspection, possible repairs, and a scheduled cleaning window. Some smaller homes can be completed in one day once we’re on site. Others with extensive duct runs or needed repairs take longer. The honest answer is: we schedule properly, show up when we say, and don’t rush through a job to hit a clock. Call (737) 727-2314 and we’ll give you a realistic timeframe for your specific system.
