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 Gilroy
Air duct cleaning in Gilroy for a typical single-family home runs $425 – $780 for a full system, and most jobs are scheduled within three to five business days. That’s the honest range we quote before anyone steps foot in your house, and it’s the number that appears on your written price before work starts. If you’re breathing dust every time the AC kicks on or your allergies spike the moment you close the windows, your ducts are probably carrying years of accumulated crud. Call (737) 727-2314 and we’ll tell you straight whether cleaning is worth it for your home.
We know Gilroy’s neighborhoods because we work them year-round: the older ranch-style homes in the downtown grid, the newer subdivisions pushing up against the eastern foothills, the rural properties out toward Gilroy Hot Springs Road and the properties tucked off Hecker Pass. Different construction, different duct layouts, same truth: this valley traps heat and your HVAC system pays for it every summer afternoon.
Why Cardinal Air Duct Cleaning Is Gilroy’s Preferred Air Duct Cleaning Company
We’re the Air Duct Cleaning specialist in the Relay Home Co. family, and every Gilroy job runs on the same standard: a written price before work begins, a live arrival window you can track from your phone, and before-and-after photos of your actual ducts when we’re done. No exceptions, no fine print. Omar Haddad built our process around one question: how would you run this business if your own mother was booking the job? The answer is what we deliver every day in Gilroy.
Gilroy homeowners tell us the same thing constantly: they’ve had quotes over the phone that ballooned once a tech walked the house. That’s the per-vent pricing trap, and it’s rampant in this market. A house off Mantelli Drive or in the Sunridge neighborhood might have 18 or 22 registers. Quote per-vent at $45 and suddenly a “reasonable” job becomes a $900 invoice for what should’ve been a $600 system cleaning. We quote per system. One flat number. It doesn’t move.
Our technicians are background-checked, uniformed, and you learn their name before they arrive. They run Rotobrush agitation systems and Nikro HEPA negative-pressure vacuums, not a shop-vac and a prayer. And the 365-Day Done Right Promise covers every job we do in Gilroy: if the work isn’t right within a full year, we come back and make it right at no charge.
Air Duct Repair in Gilroy
Air Duct Repair in Gilroy usually means one of three things: a separated duct joint bleeding conditioned air into the attic, a crushed or kinked flex duct choking airflow to one part of the house, or a return plenum that’s pulled loose and sucking fiberglass and dust straight into the blower. The Santa Clara Valley’s dry heat bakes duct sealant until it cracks, and the temperature swings between Gilroy’s hot days and cool nights accelerate that failure. A disconnected run in a crawlspace or attic can waste 20 – 30% of the air your system pays to heat or cool.
Most residential duct repairs in Gilroy run $180 – $450 per repair point, depending on access and whether we’re resealing, reconnecting, or replacing a damaged section. Every repair includes a written guarantee, and if that repair fails within 365 days, the second visit is free. That’s not marketing language; it’s the operational standard Omar Haddad enforces on every Gilroy dispatch.
Sealing and Reconnection
A duct that’s slipped off a register boot or plenum collar isn’t always obvious from the vent. We find it with a camera inspection, then reseal with mastic and mechanical fasteners, not duct tape. Duct tape dries out in Gilroy’s attic heat within a year or two. Mastic lasts decades.
Flex Duct Replacement
Crushed flex runs under a mobile home or through a tight attic chase are common in Gilroy’s older housing stock. When the inner liner tears, that duct is done. We replace the damaged section with properly sized R-6 or R-8 flex, never a patch job that fails in the same spot two seasons later.
Ductwork Cleaning in Gilroy
Ductwork Cleaning in Gilroy means cleaning the entire pathway air travels: supply ducts, return ducts, boots, plenums, and the air handler itself. Cheap outfits fog the registers and call it done. Real cleaning means connecting a negative-pressure vacuum at the plenum, agitating every run with rotary brushes, and pulling loosened debris into a HEPA-filtered containment unit, not back into your living room. Negative-pressure extraction is the trade term; what it means for you is simple: the dirt leaves your house in a sealed vacuum, not a cloud.
A full-system ductwork cleaning in Gilroy runs $425 – $780 for a typical single-family home under 2,500 square feet, with the final price locked in writing before a single duct is touched. Homes with extensive attic runs, multiple systems, or heavy construction dust may push toward the upper end. We’ll tell you if the lower half of that range is realistic for your home, and we’ll never inflate it once the van is in your driveway.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull room air back to the furnace or air handler. Both need cleaning, and the return side is often worse because it carries unfiltered air from the home. In Gilroy, that return air includes dust from foothill winds, pet dander, and whatever your shoes tracked in from Uvas Road or the garlic festival parking lots.
Video Inspection Before and After
We run a camera through your ducts before we start and again when we finish. You see both sets of photos. Not stock images, not a competitor’s portfolio. Your ducts. That’s The Relay Standard, and it applies to every Gilroy job we book.
Trusted Brands We Service in Gilroy
Our equipment fleet and the filtration products we recommend are built around brands that hold up in Gilroy’s long cooling seasons: Rotobrush rotary agitation systems that scour duct walls without damaging them, Abatement Technologies containment units that keep dust from re-entering the home during cleaning, and Aprilaire filtration media for homeowners who want better air after the ducts are cleaned. When your system needs a filter upgrade or a UV lamp, we stock Guardsman and Aprilaire products locally for fast turnaround on Gilroy installs.
Common Air Duct Cleaning Problems We See in Gilroy Homes
- Extended summer runtime packs dust into returns. Gilroy’s bowl geography means afternoon temps regularly run 15 – 20°F hotter than Morgan Hill or San Jose, so your AC cycles longer and pulls more particulate through the return. We routinely see return ducts in Gilroy homes with a quarter-inch of packed dust that would take years to accumulate in a coastal town.
- Per-vent pricing inflates the final bill. Contractors quote a low per-vent price because a house off Buena Vista Way might have 20 registers or more. By the time they count every boot and grille, the invoice looks nothing like the phone quote.
- Fog-and-go cleaning leaves the air handler untouched. Longer runtimes mean Gilroy blower motors and evaporator coils collect more dust than the ducts themselves. A cleaning that skips the air handler cleans less than half the system.
- No before-and-after proof. Many Gilroy homeowners pay for a cleaning and receive nothing but a receipt. If you can’t see what the inside of your ducts looked like before and after, you have no way to know whether the job actually happened.
Pricing for Air Duct Cleaning in Gilroy, CA
A full-system Air Duct Cleaning in Gilroy for a standard home runs $425 – $780. That’s one flat price per system: every supply run, every return run, both plenums, the boots, and the air handler. It does not change if your home has 14 registers or 24. Ductwork Cleaning follows the same flat pricing model at the same range, because it is the same job done fully. Duct repair work is quoted per repair point at $180 – $450. We hand you a written price before any work begins. Call (737) 727-2314 for a free estimate that actually means something.
Two-story homes, homes with two HVAC systems, or properties with extensive crawlspace ducting may exceed that range, and we’ll tell you that on the phone before you commit to anything. But what you’re quoted is what you pay. Omar Haddad made that rule, and it’s the reason Gilroy homeowners answer our calls on the first ring.

FAQs About Air Duct Cleaning in Gilroy
Most Gilroy homes need a legitimate full-system cleaning every 3 to 5 years, with the shorter interval applying if you have pets, recent remodeling, or family members with significant allergies or asthma. The dry summer heat and long AC runtimes here pull more dust through the system than a milder climate, which means the 3-year mark is the realistic interval for many South County households. Many of those same households also benefit from Dryer Vent Cleaning in Gilroy on a similar schedule, since lint buildup poses the same fire and efficiency risks. If your home was built recently and you change filters regularly, you may not need cleaning at all yet. Call (737) 727-2314 and describe your situation; we’ll give you an honest recommendation, even if that recommendation is to save your money.
We charge one flat price per system, not per vent, and that price is written and in your hands before any work starts. A house off Miller Avenue with 22 registers pays the same as a house with 12 registers if the system size is comparable. Per-vent pricing is how Gilroy homeowners get burned, and we refuse to play that game, full stop.
We connect a Nikro HEPA negative-pressure vacuum at the plenum, then work every supply and return run with Rotobrush agitation tools. The vacuum creates suction at the air handler while mechanical brushes scour duct walls, so loosened debris moves in one direction only: into a sealed containment unit, never back into your home. The air handler, blower motor, and coils are cleaned as part of the same job. You receive before-and-after camera photos of your own ducts, not a generic image, before we leave the property.
No, and we won’t promise it either. Honest duct cleaning is a scheduled job that takes four to six hours on site, and we book Gilroy jobs three to five business days out. That’s not a limitation; it’s what the job actually requires. Call (737) 727-2314 and we’ll lock in a window that works, tracked live through The Relay Standard so you know exactly when we arrive.
You get before-and-after camera photos of your ductwork, taken from inside the system, delivered the same day. If the photos don’t show a visible difference, the cleaning didn’t happen and you shouldn’t pay. That’s the entire point of The Relay Visibility Guarantee, and it’s standard on every Gilroy job we complete.
