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 in Houston, TX
Dryer vent cleaning in Houston runs $119-$289 for a standard single-vent job, while full duct repair and sealing work ranges from $450 to $2,400 depending on how much of the original flex duct has failed. Those numbers reflect what we see across Houston’s slab-foundation neighborhoods, where decades of attic heat and Gulf Coast humidity have done real damage to the ductwork. If you need a written price for your home, call (806) 606-6902 and we’ll put one in front of you before any panel comes off.
Why Houston Homes Are Different
Houston’s housing stock is overwhelmingly slab-on-grade, which means there is no basement and no conditioned crawlspace to hide ductwork in. Nearly every flex duct run in this city lives in an unconditioned attic that hits 140-160°F from June through September. That heat does two things over time. First, it cooks the plastic outer liner of flex duct until it turns brittle and splits at the seams. Second, it creates a temperature differential at every poorly sealed joint, and that is where Houston’s humidity condenses. The result is moisture sitting inside duct runs for months at a time.
We see this pattern most in the post-1960s tract-home corridors: Spring Branch, Sharpstown, Clear Lake, the Energy Corridor. Homes built between 1970 and 1995 often still have their original flex duct, now kinked, undersized for modern AC loads, and carrying a layer of Gulf Coast particulate that has been recirculating for thirty or forty years. In Meyerland and parts of Kingwood that took water during Harvey, we also find flood-related contamination that pushed mold spores directly into the duct system through the air handler. That is a structural contamination problem, not a dust problem.
Our Main Houston Services
Most Houston homeowners call us for one of two things: cleaning the duct system that moves air through their home, or cleaning the HVAC equipment that conditions it. Both are detailed below, with links to their dedicated Houston pages.
Air Duct Cleaning in Houston
Houston AC systems run nine or more months out of the year, and that near-continuous operation means the ductwork is collecting dust, pet dander, and mold spores almost every day. In slab-foundation homes, a thorough cleaning means extracting debris from every register back to the plenum, including the horizontal runs that sag in the heat. We photograph the inside of every run before and after, so you see what was actually removed. Learn more on our Air Duct Cleaning in Houston page, where pricing and scope are written out in full.
HVAC Cleaning in Houston
The evaporator coil, blower wheel, and drain pan inside a Houston air handler collect a thick biological film from months of condensation. When that film grows, it restricts airflow and pushes microbial particles into every room. Our HVAC cleaning removes that buildup with professional equipment, and we document the coil and blower before and after. Full details live on the HVAC Cleaning in Houston page, including what the job includes and what it costs.

BeforeAfterDryer Vent Cleaning in Houston
Dryer vent cleaning in Houston is a scheduled maintenance job that directly reduces a fire hazard, and most homes need it far more often than they realize. Houston’s humidity means lint clumps instead of blowing through, and the long vent runs common in slab-foundation homes from Spring Branch to Clear Lake give that lint plenty of surface to stick to. We photograph the inside of the vent before and after so you can see the difference between a clean run and one that was simply vacuumed at the wall.
For a deeper look at how this service works and what it includes, see our Dryer Vent Cleaning hub page.
Dryer Vent Inspection
Signs you need it
Clothes take two or more cycles to dry, the dryer exterior runs hot to the touch, or you notice a musty odor from the drum.
What it costs in Houston
A dryer vent inspection runs $89-$149 in Houston, and the price is written before the camera goes in.
How we do it
We run a camera from the dryer connection to the exterior termination, measuring the run, documenting blockages, and identifying any code or fire-safety gaps.
Vent Cleaning
Signs you need it
The exterior vent flap barely opens during operation, or visible lint has built up around the termination point outside.
What it costs in Houston
Vent cleaning costs $119-$230 for a standard single run in Houston, before any rerouting or repair work.
How we do it
We use a professional rotary brush with negative-pressure extraction to pull compacted lint and debris from the full vent run, then photograph the result.
Lint Removal
Signs you need it
You can see lint accumulating inside the vent opening within weeks of a previous cleaning, or the dryer exhaust smells hot or scorched.
What it costs in Houston
Targeted lint removal runs $119-$200 in Houston, depending on vent length and how compacted the buildup is.
How we do it
We dislodge dense lint plugs from elbows and transitions, extract them with HEPA-filtered equipment, and clear the vent to full diameter.
Vent Rerouting
Signs you need it
The existing vent run exceeds 25 feet with multiple elbows, uses vinyl or foil rather than rigid metal, or terminates in a soffit or crawlspace instead of outdoors.
What it costs in Houston
Vent rerouting starts at $420 and goes up from there in Houston, with the written price set before any work begins.
How we do it
We replace non-compliant vent runs with rigid metal duct, reduce the number of elbows, and terminate at an exterior wall with a proper dampered hood.
Bird Guard Installation
Signs you need it
Birds nest in the exterior vent hood, or you hear scratching sounds near the dryer wall during spring months.
What it costs in Houston
Bird guard installation costs $85-$160 in Houston, depending on the style of termination and roof or wall access.
How we do it
We install a metal cage-style guard over the exterior termination that blocks birds and rodents while allowing full airflow, then photograph the finished work.
What Dryer Vent Cleaning Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Dryer vent inspection | $89 - $149 |
| Vent cleaning (single run) | $119 - $230 |
| Vent rerouting | $420+ |
Longer vent runs, multiple elbows, or a second-story termination point push the price toward the upper end. The written price you receive before work starts is the price you pay, per Haven Standard Clause 1.
How often should a dryer vent be cleaned in Houston?
Every 12 to 18 months for most Houston homes, and every 6 to 12 months if you run more than four loads per week or have a vent run over 15 feet. Lint accumulates faster in Houston’s humidity. Call (806) 606-6902 for a written price.
Why does my dryer vent clog so fast in Houston?
Houston’s humidity causes lint to clump and adhere to the vent wall instead of blowing clear, especially in attic runs that cool and condense overnight. Long slab-home vent runs make it worse. Call (806) 606-6902 to schedule an inspection.
Duct Repair & Sealing in Houston
Duct repair and sealing in Houston is the difference between conditioned air reaching your rooms and conditioned air leaking into a 150-degree attic. In slab-foundation homes, where every duct run lives in unconditioned space, the original flex duct installed in the 1970s through 1990s has now been baking for decades and is split, sagging, or disconnected at the joints. We repair and seal those failures, then photograph every run so you can see exactly what was fixed.
For full service details, see our Duct Repair & Sealing hub page.
Duct Sealing
Signs you need it
Rooms are unevenly cooled, your energy bills climb in summer, or you can see daylight through joints in attic ductwork.
What it costs in Houston
Duct sealing runs $450-$1,040 in Houston depending on how many runs and joints need work.
How we do it
We locate leaks with a duct leakage tester, then seal every joint and seam with mastic sealant or foil tape rated for HVAC use.
Flex Duct Repair
Signs you need it
You find collapsed or kinked flex duct in the attic, or the duct is torn at a connection point.
What it costs in Houston
Flex duct repair runs $430-$780 per run in Houston, depending on run length and whether the insulation sleeve has failed.
How we do it
We cut out damaged sections, splice in new R-8 insulated flex duct, and reattach the run at both ends before sealing and insulating all connections.
Mastic Sealant
Signs you need it
Duct tape or aging foil tape is peeling away from joints, leaking air that you can feel with the blower running.
What it costs in Houston
Mastic sealing runs $450-$1,040 for a full system in Houston, with the price fixed per duct run before work begins.
How we do it
We apply fiber-reinforced mastic sealant to every accessible joint, which dries to a durable, air-tight seal that doesn’t peel like tape.
What Duct Repair & Sealing Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Duct sealing (full system) | $450 - $1,040 |
| Flex duct repair (per run) | $430 - $780 |
| Mastic sealing (full system) | $450 - $1,040 |
Homes with original 1970s-1990s flex duct in unconditioned attics typically fall toward the higher end because more runs have failed. Every price is written before the first panel comes off.
Can I repair my own ductwork in a Houston attic?
Working in a Houston attic when it’s 140 degrees or hotter is dangerous, and flex duct repairs done without proper sealing will keep leaking. Our crews work with the right tools and document what they fix. Call (806) 606-6902 for a written price.
How do I know the ductwork is actually sealed?
We provide a documented photo record of every run before and after the repair, plus a written scope of what was sealed and where. It is evidence you keep. Call (806) 606-6902 to schedule an estimate.
Air Quality & Sanitizing in Houston
Houston’s air quality work is different from any dry-climate city because condensation inside ductwork is a year-round condition here. In homes with original flex duct and poor joint sealing, biological growth develops inside the system and then recirculates through the house whenever the blower runs. Mold treatment and sanitizing in Houston is often a post-repair step: once leaks are sealed and moisture stops entering the system, the existing contamination has to be addressed.
See our Air Quality & Sanitizing hub page for the full scope of this service.
Mold Treatment
Signs you need it
You smell a persistent musty odor from vents, see staining around registers, or have had a moisture problem in the HVAC system.
What it costs in Houston
Mold treatment in Houston runs $550-$1,180, with the written price determined by the scope of affected ductwork.
How we do it
We apply an EPA-registered antimicrobial treatment to the affected duct surfaces after mechanical cleaning removes the visible growth.
Bacteria Sanitizing
Signs you need it
The drain pan or coil has visible biological film, or household members have unexplained respiratory irritation that improves away from home.
What it costs in Houston
Bacteria sanitizing costs $400-$865 in Houston, covering the coil, drain pan, and accessible plenum surfaces.
How we do it
We fog the accessible system interior with a sanitizing agent, then document the treatment with before-and-after photos of the affected surfaces.
Odor Removal
Signs you need it
A stale or sour smell persists after cleaning, or odors from cooking, pets, or previous occupants return when the AC runs.
What it costs in Houston
Odor removal runs $350-$750 in Houston, depending on the number of duct runs and the source of the odor.
How we do it
We identify the odor source within the duct system, clean the contributing surfaces, and apply a deodorizing treatment that neutralizes rather than masks.
UV Light Installation
Signs you need it
Mold or biofilm returns quickly after coil cleaning, or a household member has a condition that makes indoor air quality a priority.
What it costs in Houston
UV light installation runs $650-$1,350 in Houston, depending on the lamp model and coil configuration.
How we do it
We install a UV-C lamp at the evaporator coil, which continuously treats the coil surface where moisture-driven growth happens.
Air Purifier Install
Signs you need it
Dust levels remain high even after duct cleaning, or household members have allergy symptoms tied to indoor air.
What it costs in Houston
Air purifier installation runs $800-$1,900 in Houston, including the unit and the labor to integrate it into the duct system.
How we do it
We install a whole-home purifier at the plenum, wired to run when the blower operates, and photograph the completed installation.
What Air Quality & Sanitizing Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Mold treatment | $550 - $1,180 |
| Bacteria sanitizing | $400 - $865 |
| UV light installation | $650 - $1,350 |
Homes with flood history or long-standing moisture problems trend toward the upper end because the affected surface area is larger. Every price is written and agreed before work starts.
Does Houston’s humidity mean I need air quality work more often?
Generally yes. Condensation at poorly sealed joints keeps interior duct surfaces damp for months, which allows biological growth to establish faster than in dry climates. We inspect and document first. Call (806) 606-6902 for a written price.
Should I sanitize my ducts after a flood in Houston?
If floodwater reached the air handler or entered the duct system, yes, a professional assessment is the right step. Mold spores pushed into ductwork do not resolve on their own. Call (806) 606-6902 to schedule an inspection.
