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 South Houston, TX
Complete HVAC cleaning in South Houston typically runs $350-$650 for a whole-house system, with air quality and sanitizing treatments adding $200-$450 depending on contamination level. The homes here, built mostly between the 1940s and 1970s, carry ductwork that has never been professionally serviced, while the Ship Channel’s industrial emissions and Harvey’s lingering moisture damage create conditions we don’t see in other parts of Harris County. Call (346) 253-1822 for a written estimate before any work begins.
Why South Houston Homes Are Different
South Houston sits directly adjacent to the Houston Ship Channel’s petrochemical corridor, one of the densest industrial zones in North America. HVAC intakes here pull outdoor air loaded with refinery particulates, hydrogen sulfide, and industrial emissions that residential ductwork elsewhere rarely encounters. The housing stock, predominantly modest single-family homes built from the late 1940s through the early 1970s, still runs on original or first-replacement ductwork, much of it fiberglass duct board that degrades and sheds fibers directly into the airstream.
The city’s low-lying position near Ship Channel waterways and bayous produces sustained ambient humidity among the highest in the metro. HVAC systems run nearly year-round, and chronic condensation inside ductwork accelerates mold and microbial growth. Many homes took on water during Hurricane Harvey in 2017; even properties with only a few inches of standing water often saw duct interiors saturated. Owners completed surface remediation but never had ducts inspected, so we still open systems and find active mold colonies inside flex duct and air handlers that look fine from the outside.
Our Main South Houston Services
These are the three services South Houston homeowners call about most often.
Air Duct Cleaning in South Houston
We clean the full duct network, from return plenum (the distribution box where air enters the system) through every duct run (the individual passages) to each register (the room vents). In South Houston, this means addressing industrial particulate buildup, post-Harvey moisture damage, and degraded fiberglass duct board. Every job ends with a Documented Photo Record of every run, before and after. Air Duct Cleaning in South Houston
Dryer Vent Cleaning in South Houston
Dryer vent blockages are a leading cause of house fires. We remove lint buildup from the dryer connection through the exterior termination using rotary brushes and negative-pressure extraction (suction that pulls debris out rather than pushing it deeper). High humidity in South Houston causes lint to clump and stick, accelerating blockage. Dryer Vent Cleaning in South Houston
Duct Repair & Sealing in South Houston
Leaky ducts waste 20-30% of conditioned air. We seal seams and repair damaged sections, with particular attention to Harvey-flooded systems where corrosion and mold have compromised metal and flex duct. Sealing is done with mastic and metal tape, not duct tape, and every repair is photographed. Duct Repair & Sealing in South Houston

BeforeAfterHVAC Cleaning in South Houston
HVAC cleaning in South Houston addresses systems choked with refinery particulates, degraded fiberglass, and post-Harvey mold that standard filter changes cannot reach. The evaporator coils, blowers, and air handlers in these 1940s-1970s homes work harder than their design intended, running almost continuously in the humid Gulf Coast climate. HVAC Cleaning here is not maintenance; it’s remediation of conditions created by location and age.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or musty odors when the AC cycles on indicate a contaminated coil.
What it costs in South Houston
Evaporator coil cleaning typically runs $180-$320.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the before and after condition.
Blower Cleaning
Signs you need it
Vibration noise from the air handler, uneven airflow room to room, or dust puffing from registers on startup point to a dirty blower wheel.
What it costs in South Houston
Blower cleaning typically runs $150-$280.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the assembly, and reinstall with torque verification.
What HVAC Cleaning Costs in South Houston
| Item | Typical range in South Houston |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower cleaning | $150-$280 |
| Full HVAC cleaning (coil + blower + air handler) | $350-$650 |
How do I know my HVAC needs cleaning, not just my ducts?
If your registers blow clean but the house won’t cool below 78, or you smell must every time the compressor kicks on, the contamination is likely in the coil or blower, not the duct runs. We inspect these components with a borescope camera before quoting.
Will cleaning my HVAC system help with the humidity in South Houston?
A clean evaporator coil transfers heat properly and drains condensate efficiently; a dirty coil can’t dehumidify effectively. We measure static pressure before and after to document airflow improvement.
Air Quality & Sanitizing in South Houston
Air quality and sanitizing in South Houston targets mold, bacteria, and industrial contaminants that standard duct cleaning leaves behind. The combination of Harvey moisture intrusion, chronic high humidity, and Ship Channel emissions creates biofilm and particulate loads that require active treatment, not just mechanical removal. Air Quality & Sanitizing here addresses what grew in the ducts, not just what settled there.
Mold Treatment
Signs you need it
Visible mold around registers, a persistent earthy smell, or respiratory symptoms that worsen when the HVAC runs suggest active mold colonization inside the system.
What it costs in South Houston
Mold treatment typically runs $400-$800 depending on contamination extent and duct accessibility.
How we do it
We apply an EPA-registered antimicrobial fog throughout the duct network, let it dwell per manufacturer specification, then extract residue with negative-pressure equipment and photograph every treated run.
UV Light Installation
Signs you need it
Recurring mold after cleaning, or a home where occupants have mold sensitivity or compromised immunity, indicates the need for continuous suppression.
What it costs in South Houston
UV light installation typically runs $350-$600 including the lamp and power supply.
How we do it
We mount a UV-C lamp in the supply plenum where it irradiates the coil and upstream duct surfaces, wiring it to the air handler’s 24-volt terminal for automatic operation.
What Air Quality & Sanitizing Costs in South Houston
| Item | Typical range in South Houston |
|---|---|
| Mold treatment | $400-$800 |
| UV light installation | $350-$600 |
| Combined sanitizing package (mold + bacteria + odor) | $600-$1,050 |
Is the antimicrobial treatment safe for kids and pets?
We use EPA-registered products approved for HVAC application; the system is flushed and tested before we leave, and we document the product name and EPA registration number on your job record for your reference.
How long does mold treatment take?
Most residential systems require 4-6 hours including setup, dwell time, and extraction; heavily contaminated post-Harvey systems may need a second application, quoted upfront if we expect it.
