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.

Why Cardinal Air Duct Cleaning Is San Martin’s Preferred Air Duct Cleaning Company
San Martin homeowners tend to do their homework before booking a duct cleaning. They’ve seen the low-ball coupons and heard the stories about a $79 special turning into a $2,000 invoice once the tech is inside. That’s exactly why our flat-price-per-system approach resonates here.
The Relay Standard governs every San Martin booking. You get a live trackable arrival time so you’re not stuck waiting through a four-hour window. Your technician’s name and background are shared before anyone knocks on your door. And when the work is done, you receive before-and-after photographs of the actual ducts in your home, plus a digital invoice you can pay by link from your phone. That’s the Air Duct Cleaning experience Omar Haddad has built, and it’s the standard we hold ourselves to on every job across San Martin.
We know this area’s housing stock. The ranch homes off Llagas Avenue, the newer builds near San Martin Avenue, the rural properties with long driveways and aging galvanized trunk lines. Local knowledge matters when you’re quoting a duct system that was partially retrofitted in the 1990s. Our crew doesn’t guess. We inspect first, then we quote.
What truly sets us apart in San Martin: the 365-Day Done Right Promise. If the work isn’t right within a full year, we return at no charge and correct it. That guarantee covers every job. Not select ones. Every single booking, from a modest ranch on Monterey Highway to a large custom home near the southern Santa Cruz foothills.
Vent Cleaning in San Martin
Vent cleaning and Dryer Vent Cleaning in San Martin means removing the accumulated dust, pet hair, and rural road grit from each supply and return register, the boots behind them, and the accessible branch runs. Because San Martin sits in an agricultural corridor, homes here pick up a particular mix of pollen, field dust, and fine particulate that settles inside duct systems faster than you’d expect.
We see this all the time on properties near the western edge of town where open fields run up against residential streets. A standard vent cleaning for a typical San Martin home runs $150 to $300 as part of a full Air Duct Cleaning service, and it’s included in our flat per-system price, not billed separately per vent.
Supply Registers and Return Grilles
Supply registers push conditioned air into your rooms. Return grilles pull it back to the air handler. In San Martin homes with pets and nearby agricultural activity, both collect a stubborn film that ordinary vacuuming won’t remove. We pull each register, clean the boot and the first several feet of branch duct, and reset everything with a proper seal.
Boot Cleaning and Debris Removal
The boot is the metal transition piece connecting your duct run to the register. Crumbs, pet hair, and even small toys end up lodged in boots routinely. We find toy cars, crayons, and enough pet fur to build a second dog in some San Martin homes. Our vent cleaning removes all of it, and photos confirm what we found and what we removed.
Air Duct Repair in San Martin
Air duct repair in San Martin most often means reconnecting separated flex runs, sealing leaking joints, and replacing damaged sections of galvanized trunk line. Our technicians carry sheet metal, mastic sealant, foil tape, and replacement flex duct on the truck, so most repairs happen the same visit we find them.
Many San Martin homes have hybrid systems: original metal trunks from the 1970s or 1980s with newer flex branches added during remodels. The connection points are where problems start, especially at the air handler where vibration works clamps loose over time. A typical duct repair in San Martin runs $150 to $450 depending on what we find, and every repair is covered by our 365-Day Done Right Promise with a free second visit if the repair fails.
Reconnecting Separated Flex Runs
We were called to a ranch property off Llagas Avenue where the homeowner had noticed heavy dust settling on furniture within a day of cleaning, and the return registers were pulling visible lint. Our tech ran a camera inspection and found the flex supply runs had separated at two collars near the air handler, dumping air into the attic instead of the rooms. We performed source removal under negative pressure with HEPA filtration, reconnected both collars, and showed the homeowner before-and-after photographs of the trunk line and each register boot.
Sealing Leaking Joints and Trunk Lines
Leaky ducts don’t just waste energy. They pull attic or crawlspace air into your living space, and in San Martin that means bringing in whatever is up there: dust, insulation fibers, sometimes rodent droppings. Sealing those leaks with mastic and proper mechanical fasteners restores the system’s integrity. We test after sealing to confirm the airflow is where it belongs.
Trusted Brands We Service in San Martin
Our San Martin technicians work on every major duct system and air handler configuration, from legacy galvanized trunks to modern flex installations. We stock replacement components from Rotobrush and Abatement Technologies on our trucks and source additional parts locally so repair jobs don’t stall waiting on shipping. Because many San Martin homes run Aprilaire filtration systems in conjunction with their HVAC, we also carry compatible filters and can verify that your existing filtration is actually doing its job during any service visit. If your air handler is paired with a Guardsman filter housing or similar, we’ll inspect it as part of every full-system cleaning. The goal is simple: one visit, one flat price, and a system that works correctly when we leave.
Common Air Duct Cleaning Problems We See in San Martin Homes
- Legacy galvanized trunk lines combined with newer flex runs. San Martin’s mix of older ranch properties and newer rural-residential builds means duct systems often combine materials from different eras. The transition points where metal meets flex are where debris accumulates worst, and they’re rarely inspected by companies doing quick per-vent cleanings.
- Rural dust and agricultural particulate. Homes near working farmland or open fields collect a fine, pale dust that settles in ducts far faster than suburban homes. It clings to the inside of return plenums and blower compartments, and standard filter changes can’t keep up.
- Separated flex runs near the air handler. Vibration and temperature cycling work clamps loose over time. Air escapes into the attic or crawlspace instead of your rooms, and whatever is in that unconditioned space gets pulled back into circulation.
- Blower motor and evaporator coil buildup. The blower compartment and coil collect a dense lint mat in San Martin’s dusty environment. This reduces airflow efficiency and recirculates fine particles even after a duct-only cleaning. We include blower and coil inspection in every full-system service.

FAQs About Air Duct Cleaning in San Martin
Every 3 to 5 years for most San Martin homes, though rural properties with agricultural dust nearby, multiple pets, or recent remodeling may need it every 2 years. If you haven’t noticed excess dust, allergy symptoms, or reduced airflow, you may not need it yet. We’ll tell you honestly if your ducts don’t need cleaning after an inspection. Call (737) 727-2314 and we’ll assess your system before recommending anything.
By the system. One flat price, agreed in writing before work starts. San Martin homes often have irregular duct layouts where vent counts don’t reflect actual labor, and per-vent pricing games are exactly the bait-and-switch pattern we’ve committed to ending. You’ll know your total cost before we touch a single register.
We use negative-pressure extraction with HEPA filtration, meaning a Nikro vacuum system keeps the ductwork under suction while Rotobrush rotary agitation loosens debris. The loosened debris goes straight into the vacuum, not back into your living room. We clean every supply run, return run, register boot, and the blower compartment, then photograph the results. Call (737) 727-2314 for details specific to your system.
Yes. Every San Martin job includes before-and-after photos of your actual ducts, trunk lines, and register boots. You’ll see exactly what was inside your system and what it looks like when we’re done, delivered digitally as part of your invoice.
No. Duct cleaning is a scheduled service, not an emergency call, and rushing it compromises the work. We book San Martin appointments within the week, sometimes sooner, and you’ll know your exact arrival window before the day of the job. Call (737) 727-2314 to book a time that works.
