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.

AfterFull System Cleaning in Houston, TX
Full system cleaning is a complete, top-to-bottom cleaning of every component in your home’s forced-air system: supply and return duct runs, plenums, registers, grilles, air handler cabinet, blower wheel, and evaporator coil housing. In Houston, where humidity sits above 60% for most of the year and homes run their AC systems eight to ten months straight, the inside of a duct system accumulates debris faster than in virtually any other climate in the country. A full system cleaning with our Air Duct Cleaning services – not a partial clean of just the registers or just the main trunk – is the only way to restore actual airflow capacity and stop recirculating what’s built up inside.
CleanRun Duct Repair & Cleaning has documented what’s inside Houston ductwork since 2013, across more than 52,000 homes. Every job starts with a written price before any panel comes off, and ends with a photo record of every duct run – before and after – delivered to you as a standard part of the job. That’s not a policy we can waive; it’s Haven Standard Clause 1 and Clause 2, applied to every visit. If you’d like a written quote before we talk through anything else, call (346) 251-8919. You can also read more about our approach on the Air Duct Cleaning in Houston page.
When You Need Full System Cleaning
Not every home in Houston needs a full system clean on the same schedule. These are the situations where a partial clean won’t be enough – and where the camera typically confirms what the symptoms were already suggesting.
- You haven’t had the ducts cleaned in five or more years. The EPA and NADCA both point to a 3-to-5-year window as a general benchmark. Houston’s humidity accelerates the bonding of dust and organic material to duct walls, so five-year-old debris in this city is denser and stickier than five-year-old debris in a dry climate. The camera shows it clearly.
- Your home was built before 2005, or had major renovation work done. Homes in older Houston neighborhoods like the Heights, Garden Oaks, and Oak Forest frequently have original flex duct that has sagged, partially collapsed, or accumulated decades of fiberglass fiber on the interior lining. Post-renovation duct runs also trap drywall dust and insulation particulate at the first elbow – often 2 to 4 inches deep before the run makes its first turn.
- Your AC is running longer cycles than it used to. When supply runs are partially blocked with compacted debris, the system has to work harder to push conditioned air to the far registers. In a Houston summer, that means your unit runs longer, your electric bill rises, and your compressor takes additional wear. A full system clean restores duct cross-section and reduces static pressure.
- You’re seeing visible dust discharge from registers within days of vacuuming. If your furniture in Meyerland or Bellaire is coated again two or three days after cleaning, the duct system is actively redistributing what’s inside it. That’s not a housekeeping problem; it’s a ductwork problem.
- A member of your household has developed new allergy or asthma symptoms. Houston’s pollen seasons are long, and Bermuda grass, oak, and mountain cedar pollens all find their way into return duct systems through return grilles near floor level. A full system clean removes the reservoir; an air filter change alone does not.
- You’ve had a rodent intrusion, mold remediation, or flood event. Duct systems connected to homes that experienced the kind of flooding common in Kingwood, Meyerland, and other flood-plain neighborhoods during major storm events frequently show contamination well past the first register. A full system clean combined with a documented sanitizing treatment is the appropriate response – not a surface-level vacuum pass.
Our Full System Cleaning Process
This is the actual sequence of what happens on a CleanRun full system cleaning job in Houston. Nothing is skipped, nothing is substituted with a faster version of itself, and nothing starts until you’ve seen and signed a written price.
- Pre-job inspection and written scope. Before we open any access panel or pull any register, a technician walks the system with you and with a camera. We photograph the interior of each duct run from the register opening, document the condition of the air handler cabinet, note the filter condition and type, and identify any visible damage – liner separation, disconnected joints, or visible moisture. You receive a written scope and a written price at this point, before any work begins. That’s Haven Standard Clause 1. Nothing proceeds without your signature.
- Negative-pressure containment. We connect a commercial-grade collection unit – typically a Nikro or Rotobrush negative-pressure machine depending on system size – to the main trunk or a central access point. This creates negative pressure throughout the duct system, meaning any debris we agitate during cleaning moves toward the collection unit rather than back into the living space. “Negative pressure” means the system is pulling air inward, not blowing debris around. This step is what separates a real cleaning from a shop-vac-with-a-hose visit.
- Mechanical agitation of each duct run. Working from each supply and return register, we run a rotary brush system – Rotobrush equipment with brush heads sized to the actual duct diameter – through the full length of each run. The brush dislodges bonded debris, biofilm, and compacted dust from the duct walls. In Houston homes with flex duct, we use softer brush configurations to avoid tearing the interior liner. For rigid sheet metal runs common in Memorial-area homes, a stiffer brush profile is appropriate. The agitated debris travels to the collection unit through negative pressure.
- Air handler cabinet and blower wheel cleaning. The air handler is the mechanical heart of the system and is frequently skipped by lower-priced competitors. We open the cabinet, photograph the blower wheel and evaporator coil housing, and clean both with appropriate tools – typically compressed air, soft brushes, and coil-safe cleaner where the coil itself is accessible. A dirty blower wheel can reduce airflow by 15 to 20 percent on its own. We document what we find and what we do, in writing and in photos.
- Register and grille cleaning. Every supply and return grille is removed, cleaned in the field (or replaced if corroded), and reinstalled. In older Houston homes, aluminum grilles from the 1970s and 1980s are often caked on both sides with a mixture of dust and humidity-bonded particulate. We document the before condition before pulling them.
- Post-job photo record and written job summary. When the job is complete, we photograph the interior of every duct run a second time from the same register angle used in the pre-job inspection. You receive both sets of photos – before and after, every run – as a documented deliverable. This is Haven Standard Clause 2. It is not optional, and it does not cost extra. The written job summary includes what was found, what was done, what equipment was used, and the terms of your 365-Day Done Right Promise.
BeforeAfterFull System Cleaning Pricing in Houston
Full system cleaning in Houston runs between $350 and $750 for most single-family homes, with the range driven by four primary factors: total number of duct runs and registers, duct material and access conditions, whether the air handler cleaning is included (it is, on every CleanRun job), and whether any supplemental service – sanitizing treatment, filter replacement, or dryer vent cleaning – is added at the same visit.
| Home Size / Scenario | Typical Range |
|---|---|
| 1,000-1,800 sq ft (10-16 runs) | $350 - $475 |
| 1,800-2,800 sq ft (16-24 runs) | $475 - $600 |
| 2,800-4,000 sq ft (24-34 runs) | $600 - $750 |
| Homes with two HVAC systems | Add $175 - $275 per additional system |
| Post-renovation or contamination cases | Quoted individually after camera inspection |
The figures above are honest market ranges for Houston, not teaser prices. The $79 coupon model – where a low number gets a truck to your driveway and then a pressure-sale follows for the real scope – is specifically what CleanRun was built to replace. Haven Standard Clause 1 means you see the actual number, in writing, before any work begins. If the scope changes because the camera finds something we couldn’t see from the register, we stop and discuss it before we proceed.
If you have a written estimate from another company, bring it. We offer a free second opinion on any written estimate – our number next to theirs, in writing, so you can compare scope and price on equal terms. Call (346) 251-8919 and we’ll schedule an inspection at no charge.
What You Receive When the Job Is Done
The job record CleanRun delivers at the end of a full system cleaning is not a receipt. It’s a documented file that includes: before-and-after photos of every duct run photographed from the register opening, a written scope of work with each completed task itemized, the equipment used (Rotobrush mechanical agitation, Nikro negative-pressure extraction, and any supplemental tools), the technician’s name and background-check status, and the written terms of your 365-Day Done Right Promise.
The 365-Day Done Right Promise is a written accountability commitment, not a marketing phrase. If any aspect of the work is not right – if a register was left improperly seated, if a run shows the camera still catching debris at the elbow, if the blower wheel wasn’t fully cleaned – CleanRun makes it right. The promise is backed in writing on every job, and it applies for a full year from the service date.
Tomas Reyes built CleanRun around the principle that a customer should be able to evaluate the quality of the work themselves, without having to take anyone’s word for it. The photo record is the mechanism for that. Every job. Every duct run.
Houston-Specific Factors That Affect Full System Cleaning
Houston’s climate makes duct cleaning a different job than it is in Denver or Phoenix. The combination of heat, sustained humidity, and long cooling seasons creates specific conditions that are worth understanding before you schedule service.
Flex duct degradation. The majority of Houston homes built between 1985 and 2005 used flexible duct – an inner liner, a fiberglass batting layer, and an outer vapor barrier. In crawl spaces under pier-and-beam homes in Montrose and Timbergrove, or in attics in Pearland and Missouri City where summer attic temperatures routinely hit 145 to 160 degrees Fahrenheit, the inner liner of older flex duct becomes brittle and can tear if cleaned with the wrong equipment or technique. CleanRun sizes the brush head to the duct and to the liner condition, and we photograph any pre-existing damage before we touch it – so there’s no dispute about what we found versus what we caused.
Humidity and biofilm. In Houston’s high-humidity months – roughly April through October – the interior surfaces of ducts near the supply plenum and first elbow can develop a light biofilm layer when moisture condenses on cooler duct surfaces. This is not automatically a mold situation, but it is a surface condition that bonds dust more aggressively and creates a substrate that can support mold if conditions persist. A full system clean removes this layer. If our camera shows visible microbial growth, we’ll say so, show you the photo, and quote a sanitizing treatment separately before proceeding.
Allergen load. Houston sits in one of the most active allergen regions in the country. Oak pollen in spring, Bermuda grass pollen in summer, and mountain cedar in late fall all enter return duct systems through floor-level residential return grilles. In a home without a high-MERV filter on the air handler – and most Houston homes have 1-inch slot filters rated at MERV 4 to 6 – return runs accumulate a significant pollen and dust layer within a single season. We frequently find 2 to 3 inches of compacted debris at the return plenum in homes that have never been cleaned, particularly in Katy, Sugar Land, and the Energy Corridor where homes tend to run in the 2,500 to 4,000 square foot range.

FAQs – Full System Cleaning in Houston
How long does a full system cleaning take in a typical Houston home?
For a single-family home in the 1,800 to 2,800 square foot range – which covers most homes in areas like Meyerland, Pearland, or the Energy Corridor – a full system cleaning runs three to four hours from inspection to photo record. Larger homes with two HVAC systems, or homes with post-renovation debris, typically run five to six hours. We schedule a window that accounts for the actual scope, not the fastest possible visit, so the photo record at the end reflects a complete job. Call (346) 251-8919 for a specific estimate based on your home’s square footage and system configuration.
Is full system cleaning different from what competitors advertise for $79?
Yes, significantly. The $79 model typically covers a few registers vacuumed at the opening and a truck on the driveway – it does not include rotary mechanical agitation of each run, negative-pressure extraction, air handler and blower wheel cleaning, or a documented photo record. In some cases, the $79 visit functions as a door-opener for upselling additional services under pressure. CleanRun’s written price covers the full scope before anything starts – Haven Standard Clause 1 – and the photo record at the end shows every run before and after. You’re comparing a documented cleaning to a surface pass. Call (346) 251-8919 and we’ll put our number next to any written estimate you have.
How often should I have full system cleaning done in Houston?
Every three to five years is the standard range for most Houston homes under normal occupancy. If your home has pets, heavy allergen exposure, residents with respiratory conditions, or has gone through renovation work, a three-year cycle is more appropriate. Houston’s climate – specifically the humidity and long cooling season – accelerates debris accumulation compared to drier markets, so the high end of the national guideline tends to be the wrong choice for most homes here. After your first documented cleaning, the before-and-after photo record gives you an actual baseline to evaluate your system’s accumulation rate the next time.
Does full system cleaning include the air handler and blower wheel?
Yes, on every CleanRun job it does. The air handler cabinet and blower wheel are included in the standard scope for a full system cleaning – they are not an add-on or an upgrade tier. A dirty blower wheel restricts airflow and reduces system efficiency; skipping it defeats a meaningful portion of the purpose of cleaning the duct runs. We photograph the blower wheel before and after cleaning, and the condition is documented in your written job summary. If the coil itself requires chemical treatment beyond what’s accessible during a standard clean, we’ll note it in the inspection and quote it separately before touching it.
