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.
Fast, Reliable HVAC Cleaning Across Pasadena
HVAC cleaning in Pasadena runs $475-$1,150 for a complete system on a typical 1,800-2,400 sq ft ranch home, with evaporator coil cleaning alone at $195-$350. That’s the honest range, written down before we touch a single panel. Pasadena’s location next to the Houston Ship Channel means your ductwork collects a different kind of dirt than Pearland or Friendswood sees, and we’ve spent years learning exactly what that means for the air you breathe. If you want a documented answer to what’s actually inside your ducts, call (806) 606-6902 and we’ll schedule a full inspection with camera evidence.
Why CleanRun Air Duct Cleaning Is Pasadena’s Preferred HVAC Cleaning Company
Homeowners in Pasadena call us because we show them the problem before we ask them to pay for the fix. That’s been our practice since 2013. Our team knows the difference between normal dust accumulation and the gray, chemically dense film that settles on attic flex ducts in neighborhoods off Fairmont Parkway, Spencer Highway, and Red Bluff Road. When we pull registers in Pasadena homes, we expect to find particulate from refinery flaring, not just dryer lint and pet dander. That expectation shapes how we clean.
Every visit to a Pasadena home includes a written price before work starts (Haven Standard Clause 1), a full camera inspection of every duct run, and a documented photo record when we leave. HVAC Cleaning is a trade where vague reassurances are common. Ours is a written record. Our crews are background-checked, uniformed, and identified by name before they arrive.
Our HVAC Cleaning Services in Pasadena

Evaporator Coil Cleaning
In Pasadena’s Gulf Coast humidity, your evaporator coil is almost never dry. High RH levels keep condensation sitting on coil surfaces inside the air handler, and that moisture acts as a trap for Ship Channel particulates. What we find on coils in Pasadena homes is a gray paste, not light dust. We clean coils with professional-grade products and photograph the result. A typical evaporator coil cleaning in Pasadena runs $195-$350 depending on access.

Blower Cleaning
The blower wheel moves every cubic foot of air your system delivers. When it’s coated with the same sulfur-smelling residue Pasadena’s outside air deposits on rooftops, your system works harder and pushes contaminated air through clean ducts within days. We remove the blower assembly, clean each vane, and document the before-and-after. Expect $150-$275 for blower cleaning as part of a full system service.

Condenser Cleaning
Your outdoor condenser sits in the same air that carries petrochemical fallout. Condenser coils in Pasadena accumulate a visible, sticky layer faster than in inland Houston neighborhoods. We clean both sides of the coil, straighten bent fins, and check refrigerant pressures to manufacturer spec. Condenser cleaning in Pasadena typically runs $150-$300 on its own, or $100-$180 when bundled with a full HVAC cleaning.

Air Handler Cleaning
For apartment and condo residents in Pasadena’s denser complexes, the air handler is where hygiene problems concentrate. Shared systems pull from connected supply and return ducts, and one unmaintained unit can recirculate debris through multiple homes. We clean the handler cabinet, drain pan, blower, and coil as a complete assembly. Air handler cleaning in Pasadena runs $350-$700 depending on unit size and access. We photograph every component.

AfterTrusted Brands We Service in Pasadena
We service every major residential brand found in Pasadena homes: Carrier, Trane, Goodman, Rheem, Lennox, and York, plus American Standard and Bryant. Our equipment roster includes Rotobrush and Nikro agitation tools for source removal, with Abatement Technologies HEPA filtration units running on every job. That equipment matters when the debris load is fine and chemically dense. If you’re pricing other companies in Pasadena, ask what air filtration they’re running during cleaning. If the answer is a shop vac, that answers itself.
Common HVAC Cleaning Problems We See in Pasadena Homes

- Refinery particulate film on attic flex ducts. Pasadena’s 1950s-1970s ranch homes often have original or early-replacement ductwork, and the petrochemical corridor deposits a persistent film of fine particulates, VOCs, and sulfur compounds on every rooftop intake and return register. This debris is finer and more chemically dense than typical suburban dust.
- Humidity-driven mold in supply ducts. Gulf Coast humidity routinely sits at 75-90% RH, and AC systems in Pasadena run nearly year-round. Supply ducts inside hot attic spaces collect condensation that never fully dries, allowing mold colonies to establish and circulate particles into living areas continuously.
- Post-Harvey moisture hidden in plenums and subfloor cavities. Hurricane Harvey’s 2017 flooding saturated return-air plenums, subfloor cavities, and low-hung ductwork across Pasadena. Many homes were never fully remediated. A thorough camera inspection along the full duct pathway reveals mold colonies years after the water receded.
- Sagging flex duct disconnected at joints. Attic-run flex duct in older Pasadena homes sags over decades, and joints pull loose. That lets unfiltered attic air, loaded with rooftop contaminants, bypass the filter and enter your supply and return ducts directly. We find this on a significant share of Pasadena inspections.

HVAC Cleaning in Pasadena Is a Different Job

Pasadena’s duct cleaning jobs pull visibly darker, more chemically dense debris from attic flex ducts than neighboring Pearland or Friendswood. The Houston Ship Channel’s petrochemical corridor deposits a continuous film of fine particulates, VOCs, and sulfur compounds onto every rooftop intake and return register in the city. Standard cleaning crews from outside Pasadena routinely underestimate this load. They run equipment without sufficient HEPA filtration, leaving fine refinery particulates resuspended in the air and re-deposited on duct surfaces within weeks. When we clean a Pasadena home, we use Abatement Technologies HEPA filtration on every job, and we document the debris we remove. That’s the difference between a visit and a record.
We saw it clearly on a two-story brick-veneer ranch off Red Bluff Road. Our camera inspection showed a sagging 10-inch flex duct in the attic that had disconnected at a joint, pulling unfiltered attic air, loaded with Ship Channel particulates, directly into the supply and return ducts. We reconnected the joint, performed full source removal with our Rotobrush agitation tools under negative pressure, and then cleaned the evaporator coil and blower wheel, which had a gray, sulfur-smelling paste baked onto the fins from years of continuous AC runtime. If you live off Spencer Highway, Fairmont Parkway, or anywhere in the 77503, 77504, or 77505 zip codes, that’s what we look for every time.
Hurricane Harvey adds another layer Pasadena homeowners can’t ignore. Extended standing water in 2017 saturated return-air plenums, subfloor cavities, and low-hung ductwork in thousands of homes. Many were never fully remediated. Mold colonies that form in those hidden spaces don’t always produce a strong odor, especially in a house that’s been lived in continuously. We find them with camera inspections along the full lint pathway, and we document what we find. If you bought a Pasadena home since 2017, this is worth checking.

FAQs - HVAC Cleaning in Pasadena
Our camera inspections consistently show a measurably heavier, darker debris layer in Pasadena homes than in Pearland or Friendswood, driven by the Ship Channel’s continuous emissions of fine particulates, sulfur compounds, and VOCs. The film we find on attic flex ducts here is stickier and more chemically dense than typical suburban dust. Call (806) 606-6902 for an inspection that documents exactly what’s in your ducts. Estimates are free.
Yes. Mold established inside return-air plenums, subfloor cavities, or duct interiors after Harvey’s flooding can persist for years without a strong odor, especially in homes with continuous AC airflow. Odor is an unreliable indicator. A camera inspection along the full duct pathway is the only way to confirm what’s hidden. We include that inspection before any cleaning recommendation.
They absolutely do. Pasadena’s 1950s-1970s brick-veneer ranch homes often have original or early-replacement flex duct that sags, disconnects at joints, and traps decades of industrial particulate. Newer builds don’t have this problem. We inspect every joint and support before cleaning, and we reconnect or reseal what we find. That’s part of the job, not an add-on.
We schedule these jobs with building management, use compact equipment setups where parking is tight, and clean the shared air handler or blower motor as part of the scope when access allows. Skipping the shared components is how mold and debris from one unit recirculate through connected supply and return ducts. We document every component we clean. Call (806) 606-6902 and we’ll coordinate directly with your property manager.
Because Gulf Coast humidity keeps condensation sitting on coil surfaces and inside air handler cabinets nearly year-round. That moisture binds with Ship Channel particulates to form a thick, sticky paste on fins and blower vanes. In drier cities, dust stays dry and blows off. In Pasadena, it bakes on. Coil and blower cleaning here is restorative work, not routine maintenance. Expect $195-$350 for coils and $150-$275 for the blower as part of a documented service.
