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.
Aprilaire Air Quality & Sanitizing in Houston: What to Know First
We provide independent Aprilaire air quality and sanitizing service across Houston, with most scheduled jobs completed in a single visit and a written price delivered before any work begins. A typical whole-system treatment runs $380-$780 depending on the Aprilaire equipment installed, the extent of contamination found during camera inspection, and whether UV light or air purifier installation is involved. This page is for Houston homeowners who own an Aprilaire system and need mold treatment, bacteria sanitizing, odor removal, UV light installation, air purifier installation, or allergen reduction - not a sales pitch, but a documented record of what we find and what it costs to fix. Call (346) 251-8919 for a free estimate.
How Aprilaire Products Fail - and How We Fix Them
- Model 5000 Electronic Air Cleaner - ionizing wire corrosion. The tungsten wires in the 5000 series corrode faster in Houston’s Gulf Coast humidity, especially in homes west of downtown near the Energy Corridor where we see older HVAC retrofits with inconsistent condensate drainage. When the wires degrade, particulate capture drops and the unit starts producing ozone at levels that irritate sensitive occupants. We replace with OEM-spec wires or recommend a guard upgrade when the power supply shows voltage drift.
- Model 2410 and 1410 Media Air Cleaners - bypass seal degradation. The gasket seals on these cabinet-style units harden after 3-5 Houston summers, creating a bypass path that lets unfiltered air re-enter the duct run (the enclosed pathway between the plenum and the register). Homeowners notice rising dust on furniture despite new filters. We reseal with closed-cell gasket material rated for 180°F continuous exposure and photograph the pressure differential before and after.
- Model 800 Steam Humidifier - scale buildup and bacterial colonization. The electrode canister in the 800 generates steam by passing current through water; Houston’s moderately hard municipal supply leaves calcium deposits that trap organic material. The result is a musty odor distributed through every duct run. We descale with manufacturer-approved citric acid flush, replace the canister if electrode wear exceeds 30%, and treat the plenum with a botanical sanitizer registered for HVAC use.
- Model 1850 and 1830 Dehumidifiers - drain pan biofilm and coil mold. These whole-house units, common in Houston’s 2015-2025 builds in neighborhoods like The Heights and Montrose, develop slimy biofilm in the condensate pan when the drain line traps particulate. The fan then aerosolizes spores into the supply ducts. We disassemble the pan, treat with hydrogen peroxide-based cleaner at 3% concentration, and install a float switch if the original is missing - a code-adjacent practice we picked up from years of retrofit work.
- Model 1210 and 2210 Upgrade Kits - UV lamp socket fatigue. When Aprilaire UV systems are added to existing cabinets, the socket hardware sometimes loosens from thermal cycling. The lamp flickers or fails prematurely, and homeowners assume the bulb. We inspect socket tension with a torque driver, replace with ceramic-base hardware when the plastic shows heat deformation, and verify output with a UVC radiometer - not visual glow - because visible light does not indicate germicidal output.
Our Aprilaire Air Quality & Sanitizing Process

- 1
Camera inspection and written scope. We feed a borescope into every accessible duct run and photograph the plenum, elbows, and register boots. The customer sees the images before any price is discussed. The photo goes first. The pitch comes later, if it’s warranted.
- 2
Contamination identification and testing. We distinguish settled dust from active mold using moisture meters and, when indicated, surface sampling with a third-party lab. This determines whether sanitizing is sufficient or full remediation protocol is needed.
- 3
Equipment-specific parts decision. For Aprilaire components, we stock OEM filters, canisters, and UV lamps. When an OEM part is backordered - the 5000 series power supply has been intermittent since 2022 - we source quality aftermarket with equivalent specifications and document the substitution in writing.
- 4
Negative-pressure extraction and contact treatment. We attach a Nikro or Abatement Technologies HEPA vacuum to create negative pressure at the plenum, then apply Guardsman or Honeywell-sourced sanitizer directly to contaminated surfaces. No fog-and-go: every treatment is contact-based and dwell-time verified.
- 5
Reassembly, pressure test, and photo record delivery. We verify duct integrity with a smoke pencil at joints, run the system through a full cycle, and deliver before-and-after photos plus the written scope and 365-Day Done Right Promise documentation.
- 6
Follow-up scheduling. For homes with recurring humidity issues - common in Houston’s spring and fall shoulder seasons - we calendar a six-month inspection reminder at no charge.

Why Houston Homeowners Call CleanRun Air Duct Cleaning Houston for Aprilaire Work

We’ve been in Houston since 2013, and the 52,000+ homes we’ve served include thousands with Aprilaire equipment - not because we’re affiliated with the manufacturer (we’re not; we’re an independent Aprilaire service provider), but because homeowners with research habits recognize what we document. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, which matters when your Aprilaire is integrated with a mixed-manufacturer HVAC setup and the problem is at the interface, not the component. The 365-Day Done Right Promise is backed in writing on every job, not stated in marketing copy and forgotten. Tomas Reyes, our owner, keeps a notebook of every unusual duct find - not for entertainment, but because the pattern recognition means faster, more accurate diagnosis on your job.
FAQs
No, professional cleaning and sanitizing does not void an Aprilaire warranty, provided the work is performed by a qualified technician using manufacturer-compatible parts and methods. We document our process and parts used so any warranty claim you file later has a clear service history. If your unit is still under Aprilaire’s original warranty, we flag this before quoting and use OEM components where required. Call (346) 251-8919 for an exact quote - estimates are free.
If you smell mustiness when the system cycles, see visible mold near the plenum or registers, or have had water intrusion in the ductwork, sanitizing is indicated beyond filter replacement. A new filter addresses particulate capture; it does not treat biological growth on the coil, in the drain pan, or on duct surfaces. We determine which applies during the camera inspection, which is included in every estimate visit. Call (346) 251-8919 to schedule.
Repair is typically cost-effective if the cabinet and blower are sound and the unit is under 12 years old; replacement makes more sense when multiple components fail simultaneously or when efficiency standards have changed significantly. For example, a Model 5000 with corroded wires and a failing power supply often warrants full upgrade to a current media cleaner, while a Model 800 with a single worn canister does not. We provide both options in writing with a 10-year cost projection. Call (346) 251-8919 for a free estimate.
Most scheduled jobs are completed in 2-4 hours for sanitizing and minor repairs; UV installation or full air purifier cabinet replacement may extend to a full day. We do not quote arrival windows narrower than two hours because Houston traffic on I-10 or 610 can be unpredictable, and we prefer to under-promise on timing rather than rush the documentation that comes with every job. Call (346) 251-8919 to schedule.
The $79-$149 coupon model typically covers a brief vacuuming of accessible registers, not negative-pressure extraction of every duct run, contact sanitizing, or a documented photo record. We’ve opened systems after these services and found the plenum untouched. Our price includes the full scope, the equipment, the documentation, and the 365-Day Done Right Promise - all named in writing before work starts. We also offer a Free Second Opinion on any competitor’s written estimate. Call (346) 251-8919 to compare.
