Vent Cleaning in San Antonio, TX

Vent Cleaning in San Antonio, TX

Our Dryer Vent Cleaning services in San Antonio typically cost between $99 and $249 for a standard dryer vent, depending on vent length, accessibility, and how long it’s been since the last cleaning. Most jobs take 45 to 90 minutes, and we’re usually able to schedule same-week service. If your dryer is taking longer than one cycle to dry a load, or the laundry room feels humid while the dryer runs, the vent is the first place we look.

Cardinal Air Duct San Antonio handles vent cleaning as a focused service under our broader Dryer Vent Cleaning in San Antonio work. We’re part of the Relay Home Co. family, founded in 2005, which means every booking runs on The Relay Standard: a live trackable arrival time, before-and-after photos of the vent, and a written price handed to you before any tools come off the truck. Call us at (254) 347-3897 and a live person answers, 24/7, not a voicemail tree.

What makes vent cleaning different from general home maintenance work? A dryer vent isn’t just a duct. It’s a lint trap for everything your dryer pulls off clothes, towels, and bedding. Over time that lint compacts in the vent run, restricts airflow, and becomes fuel. The San Antonio climate doesn’t help. Our hot, dry summers mean dryer vents run through attics that bake at 140+ degrees for months, which makes that accumulated lint even more prone to ignition. We clean vents all over the city, from Alamo Heights to Stone Oak to Helotes, and we see the same pattern: homes built before 2000 often have original foil or vinyl vent runs that should have been replaced years ago. Newer neighborhoods like Cibolo Canyons and Alamo Ranch tend to have code-compliant rigid metal ductwork, but lint still builds just as fast when the vent run is long or has extra elbows.

Omar Haddad leads our team here, and he’s built the San Antonio operation around one simple principle: you should see what we did. That’s why every vent cleaning includes photo documentation of the vent interior before and after. No mystery, no guesswork, no “trust us” hand-waving. Just a clear visual of what came out of your vent and what the run looks like now.

When You Need Vent Cleaning

Most homeowners don’t think about their dryer vent until something goes wrong. Here are the signs we hear about most often from San Antonio customers, and what each one means in practice:

• Clothes take more than one full cycle to dry. This is the number one call we get. If towels or jeans need 90 minutes instead of 45, airflow is restricted somewhere, and the vent is the usual suspect. In a city where a family of four runs 6-8 loads a week, that extra cycle time adds up fast on your CPS Energy bill.
• The laundry room feels warm and humid while the dryer runs. That’s moisture and hot air backing up into the house instead of exiting through the exterior vent. It’s not just uncomfortable; over months it invites mold around baseboards and drywall in older homes like those around Jefferson and Monticello Park.
• The dryer feels unusually hot to the touch or gives off a faint burning smell. Hot air that can’t escape stays in the dryer cabinet. That odor is often lint smoldering inside the drum housing or the vent connector. This is the one sign we tell people not to ignore for even a day. Turn the dryer off and call us.
• It’s been more than 12 months since the last vent cleaning. The National Fire Protection Association recommends annual inspection and cleaning as needed. In San Antonio, with our hard water and dusty Oak pollen seasons, most households need it every 10 to 14 months, more often with large dogs, long-haired residents, or a lot of bath towel use.
• You can see lint or debris at the exterior vent hood. Walk outside and look at the vent cap. If you see a bird’s nest of lint around the flapper, that’s only a fraction of what’s inside the run. Birds also love building nests in dryer vents here, especially in spring, so we regularly find partial or full blockages in exterior vents around Terrell Hills and Olmos Park.
• You just bought an older home in San Antonio. Pre-2000 construction often has accordion-style foil ducting, which catches lint at every rib. Some of the houses we service around Beacon Hill and Alta Vista still have original 1970s vinyl vent runs, which current code has banned for years.

If any of these sound familiar, call (254) 347-3897. We’ll tell you over the phone whether it sounds like a simple cleaning or something that needs a closer look, and we’ll give you a written price before we start.

Our Vent Cleaning Process

Every vent cleaning follows the same six steps. It’s not a guessing game, and you’ll see the results with your own eyes.

1. Inspection and airflow measurement. We start by checking the exterior vent cap, measuring airflow at the dryer connection, and understanding how long the vent run is, how many elbows it has, and what material it’s made from. This is where we catch problems like crushed ductwork, disconnected joints, or an exterior flapper that’s been painted shut by a previous owner.
2. Written price before any work. Once we know what we’re dealing with, we hand you a written quote. That price does not change at the door, period. If we find something unexpected mid-job, we stop, show you, and get your sign-off before doing anything extra.
3. Rotary brush cleaning through the full vent run. We feed a rotating brush system through the entire duct from the dryer connection to the exterior vent. The brush action breaks up compacted lint, pet hair, and the fine dust that settles into every seam and bend. For most residential runs, this takes 20-30 minutes of actual cleaning time.
4. HEPA vacuum extraction. As the brush loosens debris, a HEPA-rated Nikro vacuum pulls it out of the vent run into a sealed collection unit. This is negative-pressure extraction, which means the loosened lint goes into the vacuum, not back into your laundry room or your lungs. Cheap vent cleaning services often blow debris outward with a leaf blower or push it back into the house. We never do that.
5. Exterior vent cap cleaning and flapper check. We clear the vent hood, remove any nesting material, and test the flapper to make sure it opens and closes properly. A stuck-open flapper in San Antonio is an open invitation for birds, roaches, and the occasional scorpion in the western suburbs.
6. Before-and-after photo documentation. You get photos of the vent interior before we start and after we finish, plus a photo of the debris we pulled out. This is part of The Relay Standard and it applies to every single job. No exceptions.

If we find a repair issue during cleaning, whether it’s a cracked vent run, a disconnected joint, or damaged vent cap, we’ll show you the photo, explain the fix in plain language, and give you a written guarantee on any repair we make. If that repair fails within 365 days, our Done Right Promise means we come back and correct it at no charge.

Vent Cleaning Pricing in San Antonio

No one likes a mystery number. Here’s How Much Does Dryer Vent Cleaning Cost? (2026 Price Guide) - San Antonio, TX, based on the jobs we’ve done across the city this year.

Service	Typical Price Range in San Antonio
Standard dryer vent cleaning (single dryer, roof or wall vent)	$99 – $149
Long or multi-story vent runs (25+ feet, multiple elbows)	$149 – $199
Vent cleaning with bird nest or rodent removal	$179 – $249
Vent cap replacement (if damaged or missing)	$49 – $89 additional
Vent run replacement (rigid metal ducting, per foot)	$12 – $18 per linear foot

What changes the price? Three things. Vent length is the biggest factor: a 6-foot run behind a garage laundry room is fast, but a 30-foot run from a second-floor laundry in a Stone Oak or Dominion home takes longer. Accessibility matters too: roof vents in two-story homes require a taller ladder and more setup time. And condition matters most of all: if the vent hasn’t been touched in five years or has a bird’s nest packed inside, that’s a different job than routine annual maintenance.

Every quote is free, and it’s a real written number, not a range with an asterisk. Call (254) 347-3897 and we’ll ask a few questions about your home and give you a firm quote before you commit to anything.

Why San Antonio Homes Need Vent Cleaning More Than Most

A dryer vent in San Antonio works harder than one in, say, Minneapolis or Seattle. Here’s why that matters for your home specifically:

Our clay-heavy soil and hard water mean clothes come out of the wash with more mineral residue and fine particulate than in softer-water regions. That translates to more dust and lint in the dryer’s exhaust stream. Add in our seasonal pollen, especially the cedar surge in January and oak in March, and San Antonio dryer vents collect more debris per load than national averages. Anecdotally, we pull significantly more lint volume from a 12-month-old vent in Helotes or Shavano Park than from a comparable home in less dusty climates.

The second factor is attic heat. Many San Antonio homes route dryer vents through the attic before exiting through the roof or soffit. In July and August, attic temperatures regularly exceed 130 degrees. That heat dries the lint inside the vent into a brittle, papery fuel. It also warps and cracks old vinyl or foil ductwork, which creates gaps where lint escapes into the attic. Those gaps are invisible from the laundry room, but they’re one reason homeowners in older neighborhoods like Shearer Hills and Dellview sometimes report a burning smell with no obvious source.

Third: the pest problem. Birds, squirrels, and wasps all use dryer vents as sheltered nesting sites in central and south Texas. We’ve pulled everything from chimney swift nests in Alamo Heights to a fully intact paper wasp nest in a Castle Hills vent cap. A properly installed vent cap with a working flapper stops most of this, which is why we always include a Dryer Vent Inspection and test the cap as part of every cleaning.

Vent Cleaning vs. Duct Cleaning: What’s the Difference?

People sometimes confuse dryer vent cleaning with air duct cleaning, and they’re not the same service. Dryer vent cleaning addresses the single exhaust line that carries hot, damp air from your dryer to the outside. Air duct cleaning addresses the HVAC distribution system: supply and return ducts, registers, and the air handler that moves conditioned air through your home. A dryer vent is typically 4 inches in diameter and carries lint, moisture, and heat. Your HVAC ducts can be 6 to 16 inches and carry the air you breathe all day. Both matter, but they’re separate systems with separate failure modes.

We specialize in both. The same Rotobrush rotary brush equipment and Nikro HEPA extraction we use on HVAC ductwork gets scaled down for dryer vent runs. The principles are identical: agitate the debris, extract it under negative pressure, verify with photos. But the vent work is faster, more focused, and typically done in under 90 minutes from arrival to final photo.

Frequently Asked Questions About Vent Cleaning

How much does dryer vent cleaning cost in San Antonio?

Most standard dryer vent cleanings in San Antonio run from $99 to $149 for a typical single-family home with a roof or wall vent. Longer runs, multi-story homes, or vents with pest blockages run $149 to $249. The exact price depends on vent length, accessibility, and condition, and we always provide a written quote before starting. Call (254) 347-3897 for a free estimate based on your specific home and vent setup.

Can you clean my dryer vent the same day I call?

In most cases, yes. We keep same-day and next-day slots open specifically for dryer vent work because a blocked vent is often urgent rather than preventive. A vent that’s causing burning smells or zero drying function deserves same-day attention, not a two-week wait. Call (254) 347-3897 and a live person will check our schedule immediately.

Is it cheaper to clean a dryer vent or replace it?

If the existing vent run is rigid metal ductwork in good condition, cleaning at $99 to $149 is almost always the better value. But if the vent is old foil or vinyl, crushed, disconnected, or packed with years of compacted lint, replacement often makes more sense. Replacing a vent run typically costs $12 to $18 per linear foot, so a 15-foot run costs $180 to $270 to replace. That’s not dramatically more than a heavy-duty cleaning, and replacement eliminates the underlying problem rather than just clearing it. We’ll show you photos and give you both options with clear pricing either way.

What happens if my vent is still clogged after cleaning?

It won’t be. We don’t leave a job until the vent run is cleared end to end and the airflow test shows proper exhaust velocity. If for any reason the vent clogs again within 365 days due to something we missed, our Done Right Promise means we return and correct it at no charge. That’s the longest satisfaction window in the trade, and it applies to every job we do, not select ones.

Does Cardinal Air Duct San Antonio clean bathroom and kitchen vents too?

We focus on dryer vent cleaning and HVAC duct cleaning, which are our two core specialties. Bathroom exhaust fans and kitchen range hoods are separate systems with their own maintenance needs, and we’d rather refer you to the right specialist than take on work outside our expertise. If you’re not sure which type of vent you’re dealing with, describe it over the phone and we’ll point you in the right direction, even if that means someone else.

What to Expect When You Book

This is the part where most home service companies make you wait. We don’t. When you call (254) 347-3897 to book a vent cleaning, here’s what happens:

You talk to a live person immediately, 24/7, not a phone tree. We gather the details: your address, the age of the home, where the dryer is located, and any symptoms you’ve noticed. We give you a written price by text or email before the appointment. On the day of service, you get a live arrival window you can track on your phone, the same way you track a rideshare. Your technician arrives in uniform, introduces himself by name, and shows you a company ID. He does the inspection, confirms the written price on site, and gets your okay before starting. When the work is done, you get before-and-after photos of the vent and a digital invoice you can pay by link from your phone.

That’s The Relay Standard. It’s the same experience on every job, and it’s the reason we don’t need to ask for repeat business. The process does the talking.

Neighborhoods We Serve

We clean dryer vents across the entire San Antonio metro. Here’s a real-world look at what we see in specific neighborhoods, because a home in Alamo Heights doesn’t need the same thing as a home in Westover Hills.

Alamo Heights and Terrell Hills: Older homes, many with original mid-century vent runs through attics and roofs. Lots of foil ductwork that should have been replaced decades ago. We also find bird nests in these neighborhoods more than anywhere else, thanks to mature trees and warm roof cavities.

Stone Oak and Sonterra: Newer construction with long vent runs from second-floor laundry rooms to roof or gable exits. Access is the main challenge here, and these cleanings skew toward the $149 to $199 range because of length and ladder work.

Alamo Ranch, Cibolo Canyons, and the far west side: Fast-growing areas with newer code-compliant venting. The main issue here is dust, which in these neighborhoods is relentless. Annual cleanings keep things moving, and we recommend them on a strict 12-month schedule.

Helotes, Grey Forest, and the northwest corridor: These are oak and cedar country. Vents here collect more pollen and fine particulate than almost anywhere else in the metro. We also find more rodent activity in exterior vents, especially where homes back up to greenbelts.

Downtown, King William, and Southtown: Historic homes with short vent runs but decades of deferred maintenance. These cleanings tend to be faster, but we often find crushed ductwork behind walls or under piers that requires repair before cleaning makes sense.

Schertz, Universal City, and the northeast side: A mix of ranch homes from the 70s and 80s with attic vent runs. The heat factor is the same as everywhere in San Antonio, and old vinyl duct that spent 40 summers in a 130-degree attic is usually ready for replacement.
