Residential Duct Cleaning in San Antonio, TX

Residential Air Duct Cleaning in San Antonio typically runs between $299 and $649 for a standard single-family home, completed in one visit, with a written price delivered before any panel comes off. CleanRun photographs the inside of every duct run before and after the job – so you can see exactly what was there, and exactly what left with our truck.

If you’ve noticed more dust on surfaces a day after cleaning, uneven airflow between rooms, or an odor that kicks on with the fan, those aren’t quirks of your house – they’re usually symptoms that start inside the ductwork. Our Air Duct Cleaning in San Antonio service covers the full system, and this page covers residential work specifically: what we do in your home, what it costs, and what you receive in writing when we’re done.

To schedule a visit or get your written price, call (726) 600-7155. A live person answers every call.

When You Need Residential Duct Cleaning

Not every home needs duct cleaning on the same schedule. San Antonio’s climate – long, hot summers that keep HVAC systems running nearly year-round, combined with the fine caliche dust that moves through the Hill Country corridor – means ducts here accumulate debris faster than homes in milder climates. These are the situations where a documented cleaning is worth scheduling:

• Visible dust discharge at supply registers. If you can see a gray film forming on the grille face within days of wiping it down, particulate is moving through the duct run and depositing at the exit point. That film is a measurable symptom, not a housekeeping problem.
• You’ve recently completed a renovation. Drywall dust, fiberglass particles from new insulation, and wood debris travel directly into open duct runs during construction. Homes in Alamo Heights, Stone Oak, and Helotes – where remodels are common in older ranch-style stock – frequently show this type of contamination on camera.
• A household member has unexplained allergy or respiratory symptoms indoors. This doesn’t mean duct cleaning is a medical intervention – it isn’t. But airborne particulate, mold spores trapped in fibrous liner, and animal dander in the ductwork can contribute to indoor air quality problems that a camera inspection will either confirm or rule out.
• You moved into the home and have no cleaning record. Most home sellers cannot produce duct cleaning documentation. If the previous owners had pets, smoked indoors, or ran the system without regular filter changes, what’s inside the plenum (the main distribution box feeding your duct runs) is often years of accumulated material.
• Uneven airflow between rooms on the same floor. Partial blockages inside duct runs – including collapsed flex duct sections common in San Antonio homes built between 1985 and 2005 – restrict airflow and cause the system to work harder to compensate. A camera shows exactly where the restriction is before any work begins.
• The system has a musty odor when the fan runs. In San Antonio’s humidity, condensation can form inside duct runs and on the evaporator coil. Organic material in those conditions can develop into a real problem. The camera inspection documents what’s there so you’re deciding based on evidence, not a technician’s verbal description.

Our Residential Duct Cleaning Process

Every step below happens on every job, in this order. Nothing is skipped based on the job size or the ticket price.

1. Written price before anything else. Tomas or one of our uniformed technicians walks the home, counts duct runs, notes system configuration, and delivers a written price. This isn’t an estimate that changes at the invoice – it’s the number under Haven Standard Clause 1, which means the written price is the price you pay. If conditions inside the system warrant additional work (for example, a discovered mold colony or a disconnected duct section), that’s a separate written scope before any additional work starts.
2. Pre-cleaning camera documentation. Before we open a single register, we photograph the inside of each duct run using inspection-grade equipment. You receive those images as part of your standard job record. This step exists so the before condition is on record – not described by us, but visible to you.
3. Negative-pressure extraction setup. Negative-pressure extraction means we connect equipment at the main trunk or plenum to create a controlled vacuum across the duct system. Air and debris move toward the extraction point rather than back into your living space. We use Nikro and Rotobrush equipment for this stage – both are trade-standard brands you can verify independently before you agree to a price.
4. Mechanical agitation of each duct run. A shop vacuum alone doesn’t dislodge debris bonded to duct liner or lodged at elbows. We run mechanical brushes or pneumatic agitation tools through each run while the negative-pressure system is active, so loosened material is captured rather than redistributed. This is the step that separates documented duct cleaning from vacuum noise.
5. Register and grille cleaning. Each supply and return register is removed, cleaned of accumulated dust and debris, and reinstalled. In older San Antonio homes – especially those with original grilles from the 1970s and 1980s in neighborhoods like Terrell Hills or Monte Vista – we sometimes find registers that haven’t been removed in decades. We photograph those too.
6. Post-cleaning camera documentation and written job record delivery. After extraction is complete, we re-photograph every duct run and compile before-and-after images into the job record you receive. That document also includes the written scope, the written price, and the 365-Day Done Right Promise in writing. If anything isn’t right within 365 days of the job, we return and make it right – that’s backed in writing on every job, not subject to manager approval.

Residential Duct Cleaning Pricing in San Antonio

Residential duct cleaning in San Antonio is priced by job scope, not by a coupon that expands once the technician is in your home. Every price below reflects a written quote delivered before work starts – no exceptions, under Haven Standard Clause 1.

Several factors shift the price within these ranges:

• Duct material: Older homes in San Antonio with rigid sheet metal runs are straightforward. Flex duct systems, common in homes built across the city from the late 1980s onward, sometimes require more care around connection points that can be fragile.
• Access: Attic-run systems in South Texas heat are physically demanding to work in during summer. We factor access conditions into the written price upfront.
• System condition: If the camera finds a disconnected section, collapsed flex duct, or a mold issue that requires treatment, that’s a separate written scope and price before we proceed.
• $79 coupons: If you’ve received a coupon in that range, bring it to us. We’ll put our written number next to it at no charge – that’s our Free Second Opinion on any written estimate. The comparison is yours to make.

To get your written price for your specific home, call (726) 600-7155. We don’t have a “call for a quote” policy – we come out, assess, and hand you a number in writing.

FAQs – Residential Duct Cleaning

How often should I have my ducts cleaned in San Antonio?

Most San Antonio homes benefit from a documented cleaning every 3 to 5 years under normal occupancy. Homes with pets, smokers, recent renovations, or residents with respiratory sensitivities are typically better served on a 2 to 3 year cycle. San Antonio’s near-year-round HVAC runtime accelerates particulate accumulation compared to homes in cooler climates where systems run seasonally – that’s a real difference, not a sales pitch. The Video Inspection at the start of each visit documents what’s actually inside your runs, so you’re scheduling based on evidence rather than a calendar. Call (726) 600-7155 and we’ll give you a written assessment, not a recommendation tied to a service package.

Is residential duct cleaning worth it, or is it mostly a scam?

Documented duct cleaning performed with proper negative-pressure extraction and mechanical agitation is a legitimate service with measurable outcomes. The scam version – which does exist and is common in San Antonio – involves a low-coupon price, a shop vacuum, and no before-or-after documentation. The way to tell the difference is to ask for the pre-cleaning photos before any work starts and the post-cleaning photos when the job is done. If a company can’t produce those, you have no evidence the work happened. CleanRun has photographed the inside of every duct run on every job since 2013 – that record exists for every one of the 52,000-plus homes we’ve served, and we can show you what that documentation looks like before you commit to anything.

What is the 365-Day Done Right Promise, and does it actually apply to my job?

The 365-Day Done Right Promise means that if the work isn’t right within 365 days of your job date, CleanRun returns and makes it right. It’s written on your job record – not a policy we cite verbally and interpret later, and not subject to manager approval. It applies to every residential duct cleaning job we complete, without exception. If you have a documented concern after the job – dust returning faster than it should, an odor that comes back, anything tied to the work we did – call (726) 600-7155 and we address it under the Promise, in writing.

Do I need to do anything to prepare my home before the technicians arrive?

Clear a few feet of access around each supply and return register – that’s the main thing. In homes with furniture positioned over floor registers, which is common in San Antonio’s older bungalow-style layouts in neighborhoods like King William and Mahncke Park, moving that furniture ahead of time saves time on both sides. We’ll handle the rest: all equipment setup, protection of floor surfaces near access points, and reinstallation of every register and grille. You receive a confirmation with technician name and arrival window before the visit – Haven Standard Clause 3: Verified Crews – so you know exactly who to expect at your door.
