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.

AfterAir Duct Cleaning Company in San Mateo, CA
Air duct cleaning in San Mateo runs into a problem most Peninsula cities don’t have: the bay. Persistent marine-layer fog keeps crawl spaces and attics damp for long stretches, and much of the city’s 1950s-to-1970s housing stock had forced-air systems retrofitted into spaces never designed for them. The result is ductwork that pulls in moist under-floor air, holds it, and slowly builds up the kind of debris you can smell when the heat kicks on. We’re Morton’s Air Duct Cleaning, and we’ve spent years working with San Mateo homeowners to clean and reseal systems that fight this exact battle. Call (323) 918-4345 and we’ll walk you through what your system needs.
Why San Mateo Homes Are Different
San Mateo sits directly on the bay shore of the Peninsula, where overnight marine fog settles in and stays. That consistent humidity is the single biggest factor in how ductwork performs here. In drier inland cities, dust stays dry and tends to blow through. In San Mateo, moisture migrates into unsealed duct joints, mixes with accumulated dust and pet hair, and creates a sticky residue that clings to duct walls. Systems that run infrequently, which is common in San Mateo’s mild climate, let that moisture sit undisturbed for weeks at a time.
Then there’s the housing stock. Core residential neighborhoods like Baywood, Shoreview, and North Shoreview are dominated by 1950s-to-1970s ranch and post-war tract homes, many of which were originally built without central forced air. The HVAC came later, routed through vented crawl spaces in configurations that were never part of the original design. Flex duct connections and sealing have now degraded through 40 to 60 years of bay-humidity exposure. In the lower-elevation bay-front areas, our technicians regularly find 1970s-era flex duct that has sagged or partially disconnected at the boot, meaning the system is actively pulling humid under-floor air instead of conditioned air. Cleaning alone won’t fix that. Resealing is half the job.
Our Main San Mateo Services
Two services cover nearly every call we field from San Mateo homeowners: full air duct cleaning and dryer vent cleaning. Each has its own dedicated San Mateo page with pricing and specifics. Here’s a quick look at both.
Air Duct Cleaning in San Mateo
Air duct cleaning in San Mateo homes means more than running a brush through the main trunk line. Because so many systems here were retrofitted through crawl spaces, our technicians spend real time checking boots, flex connections, and sealing at every accessible joint. We run professional Rotobrush and Nikro equipment through the full system, then document what came out and what was resealed. Floors and furniture stay protected the whole time: shoe covers on, drop cloths down, and a photo of the clean-up before we leave. See full details on our Air Duct Cleaning in San Mateo page.
Dryer Vent Cleaning in San Mateo
Dryer vents in San Mateo run into the same humidity problem as ductwork, plus lint, which holds moisture and clumps. A vent that’s partially blocked makes the dryer run longer, and in bay-humidity conditions that clumped lint can sit damp for weeks. We clean the full vent run from dryer to exterior termination, check airflow at the exit point, and let you know if the vent routing itself is creating a recurring problem. Every job includes the written price before we start and the 365-Day Done Right Promise. Details are on our Dryer Vent Cleaning in San Mateo page.

Pricing for Air Duct Cleaning Company in San Mateo, CA
Here are the price ranges San Mateo homeowners can expect. These are whole-system ranges, not per-vent teasers.
| Service | Typical range in San Mateo |
|---|---|
| Full system air duct cleaning (average 8-12 vent home) | $450 – $750 |
| Air duct cleaning for a larger two-story home | $650 – $950 |
| Dryer vent cleaning (standard single run) | $90 – $165 |
| Dryer vent cleaning with roof termination | $140 – $220 |
| Dryer vent cleaning for long runs (25+ feet) | $150 – $250 |

| Furnace or air handler only (with duct clean) | $80 – $150 |
| Crawl space access and inspection (when applicable) | $60 – $120 |
The two things that push price higher in San Mateo are crawl-space access and retrofitted duct routing. Older ranch homes in neighborhoods like Shoreview often have awkward, non-standard configurations that take longer to work through properly. Whatever the number, it’s a written price agreed before any work starts, and nobody on the crew is authorized to pad it afterward.
