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 San Marino
Air duct cleaning in San Marino usually costs between $450 and $850 for a full system on a typical 2,000 to 3,500-square-foot home, and most jobs are completed in a single visit. We also offer Dryer Vent Cleaning in San Marino for homes that need both services. The honest catch here is that San Marino’s houses are almost all retrofits: the city was largely built out between 1910 and 1950, long before central air was standard, so no two duct layouts are alike. That’s exactly why we don’t quote per-vent prices or hand you a firm number over the phone before someone actually looks at your system. Omar Haddad leads our crews, and every job begins with a written price agreed before a single register is touched. Call (737) 727-2314 and a live person answers, day or night.
Why Cardinal Air Duct Cleaning Is San Marino’s Preferred Air Duct Cleaning Company
We’re part of the Relay Home Co. family, founded in 2005, and we built our reputation on saying what something costs before work starts. San Marino homeowners tend to ask sharper questions than most: they want to know what equipment we’re using, who’s coming to the door, and what happens if the work falls short. Those are fair questions, and we answer them straight. Our Air Duct Cleaning teams run Rotobrush rotary brush systems and Nikro HEPA extraction units, not shop vacs in a truck. Every technician is background-checked, uniformed, and you’ll know their name before they arrive.
Serving San Marino means understanding that the homes off Huntington Drive, around Lacy Park, and up St. Albans Road were built before standardized ducting existed. We’ve worked crawlspace runs, closet-mounted air handlers, and attic-flex retrofits that generic duct cleaners never see in newer suburbs. The Relay Standard applies to every booking here: a live trackable arrival window, before-and-after photos of your own ducts, and a digital invoice you can pay from your phone.
Air Duct Inspection in San Marino
Air Duct Inspection in San Marino is a camera-and-scope walkthrough of your supply and return runs, air handler, and blower compartment, and it’s the step that separates an honest quote from a guess. Given that nearly every home in San Marino is a retrofit with non-standard duct paths, an inspection is how we find collapsed flex sections, disconnected joints, and buildup behind closet-mounted air handlers before any cleaning starts. A standalone video inspection in San Marino runs $95 – $150, and that cost is credited toward the cleaning if you proceed within 30 days.
What the Camera Actually Shows
We snake a small camera into your duct runs and look at the places registers can’t reveal: 90-degree elbows behind plaster walls, the return plenum, and the blower wheel itself. San Marino’s older homes often have original gravity-furnace runs that were repurposed, and those transitions are where dust packs in.
When You Should Get One
If you smell a musty odor when the blower kicks on, see dust puffing from registers, or noticed a room that never warms or cools correctly, an inspection finds the cause instead of just treating the symptom. It also gives you the photo evidence to see what’s actually inside your system.
Residential Air Duct Cleaning in San Marino
Residential Air Duct Cleaning in San Marino means cleaning the entire system: supply ducts, return ducts, the air handler, blower motor, and plenums. For a typical San Marino home, this runs $450 – $850 depending on the number of runs, access difficulty, and whether we’re dealing with original crawlspace runs or newer flex duct. The price is one flat number for the whole system, written down and handed to you before any work begins.
Source Removal, Not Just Registers
We set negative pressure at the air handler using a Nikro HEPA extraction unit, then work the duct runs with agitation tools from each register. That negative-pressure extraction means loosened debris gets pulled into the vacuum and filtered, not blown back into your living room. Retrofit systems with long attic or crawlspace runs need the agitation step done carefully, which is why we take our time.
Air Handler and Blower Cleaning
On San Marino’s closet-mounted retrofit systems, the blower wheel and air handler cabinet are usually the dirtiest parts of the system. We remove the blower housing, clean the wheel, and vacuum the cabinet before resealing everything. Skipping this step is what leaves a house smelling musty a week after a “cleaning” that only touched the registers.
Trusted Brands We Service in San Marino
We work on systems from every major manufacturer, including Honeywell, Aprilaire, and Guardsman filtration units that many San Marino homeowners have added to their retrofit systems. If you run a Guardsman media filter or an Aprilaire whole-home purifier, we know how to clean around them without damaging the housing or the seals. We carry common filter sizes and replacement flex duct on our trucks, which means fewer return trips when a section needs replacing during a cleaning. Our Rotobrush and Nikro equipment is calibrated for the tight, non-uniform duct runs common in this city’s older homes.
Common Air Duct Cleaning Problems We See in San Marino Homes
- Closet-mounted air handlers packed with dust. Retrofits from the 1930s – 1950s often put the air handler in a hallway closet, and that closet becomes the dust reservoir. Any legitimate cleaning has to open the blower cabinet, not just the registers.
- Collapsed flex duct in crawlspaces. Homeowners in the blocks off Oxford Road and around Virginia Road often have original crawlspace runs where old flex sections have kinked or collapsed over decades. That restriction starves rooms of airflow no matter how clean the ducts are.
- Tight 90-degree transitions loaded with debris. Retrofit layouts bend around chimneys, plumbing, and structural beams, and every bend is a collection point. Camera inspection shows these blockages clearly before we begin.
- Return-side leakage pulling dust from wall cavities. Older San Marino homes sometimes have return ducts that have separated inside walls, pulling attic dust and insulation into the system. We find and reseal those gaps during the cleaning process.
Pricing for Air Duct Cleaning in San Marino, CA
A full residential air duct cleaning in San Marino runs $450 – $850 for a typical home, with most jobs landing between $525 and $650. Larger homes with more than 20 runs or difficult attic and crawlspace access can push toward the high end. Commercial or multi-system properties are priced after an on-site walkthrough. We don’t quote per vent because San Marino’s retrofits make that number meaningless until we see the actual layout. You get one written price per system before we start, and it doesn’t change at the door. Our 365-Day Done Right Promise covers every job: if the work isn’t right within a full year, we come back and make it right at no charge. Call (737) 727-2314 for a free estimate.

FAQs About Air Duct Cleaning in San Marino
No, and we’ll tell you that straight. If a camera inspection shows clean runs, minimal dust at the registers, and a clear blower wheel, we say so and charge only the inspection fee. San Marino’s older retrofits do tend to accumulate more debris than newer homes because of crawlspace and attic runs, but we never recommend a cleaning that isn’t warranted. Call (737) 727-2314 to schedule an inspection first.
Because a 1930s San Marino house might have six registers or sixteen, and the difference isn’t visible from the curb. Per-vent pricing invites bait-and-switch games. We’d rather spend 30 minutes looking at your actual layout, then hand you one written number for the entire system. That number is fixed before work starts and won’t change at the door.
Most San Marino homes benefit from a full cleaning every 3 to 5 years, though homes with shedding pets, recent remodeling, or long crawlspace runs may need it sooner. If you’ve just completed a renovation anywhere in the city, construction dust settles in duct runs fast. Retrofitted systems with closet air handlers often show blower-wheel buildup within 2 to 3 years. We’ll tell you what we see, not what a schedule says.
You book, get a live trackable arrival window, and know your technician’s name before they come to the door. We inspect, hand you a written price for the full system, and get your approval before touching anything. Then we clean, photograph everything before and after, and send you a digital invoice you can pay from your phone. We ran a job in the Huntington Library-adjacent blocks off Oxford Road where a 1930s house had a retrofit air handler in a hallway closet feeding original crawlspace runs. The return side was packed with decades of dust plus one collapsed flex section. We set negative pressure at the air handler, cleaned the runs, swapped the failed section, and resealed everything before handing over before-and-after photos the same day. The homeowner’s musty smell was gone on the first blower cycle.
We don’t promise same-day service because San Marino’s retrofit systems genuinely deserve a scheduled, unhurried visit. Most inspections are scheduled within 2 to 4 business days, and cleanings are booked shortly after. When you call (737) 727-2314, a live person answers and gives you a real time frame, not a vague window.
