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.

AfterGuardsman Air Quality & Sanitizing in Spring: What to Know First
CleanRun provides independent Guardsman air quality and sanitizing service in Spring, TX, with written pricing delivered before any work begins and a documented photo record of every duct run included as standard. Most Guardsman UV light, air purifier, and whole-home sanitizer jobs in Spring are completed in a single scheduled visit, with mold treatment and bacteria sanitizing typically requiring two to four hours depending on system configuration and contamination level. We are not affiliated with or authorized by Guardsman; we are an independent service provider who works on the Guardsman equipment already installed in your home. If you own a Guardsman air quality product and need sanitizing, odor removal, or purification service in Spring, Gleannloch Farms, or nearby, call us at (346) 423-3631 for a free written estimate.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GUV-100 and GUV-200 series UV lights lose output intensity after 9,000-12,000 hours. The 254-nanometer germicidal lamp degrades predictably, but Spring homeowners often don’t realize the bulb still glows visibly while producing almost no effective UV-C output. We measure actual microwatt intensity at the coil surface with a calibrated radiometer - if it’s below 40 µW/cm², the lamp is replaced regardless of visible light. Haven Standard Clause 1 applies: the written price includes the new lamp, the intensity reading, and the post-installation verification photo.
- Guardsman GAP-500 whole-home air purifiers develop oxidizer cell fouling in Spring’s high-humidity months. The catalytic oxidation matrix traps ambient moisture plus HVAC condensate, creating a biofilm that reduces ion output and can produce a sharp, metallic odor through registers. We pull the cell, photograph the fouling pattern, and either deep-clean with manufacturer-specified solution or recommend replacement if the titanium-dioxide coating has degraded. The camera doesn’t negotiate - the photo shows whether cleaning will restore performance.
- Guardsman GOS-300 ozone generators in Spring homes often run at excessive output for the conditioned square footage. Older installations near Gleannloch Farms were sometimes spec’d for larger homes, producing residual ozone above 0.05 ppm that irritates lungs and degrades rubber HVAC components. We test ambient ozone with a calibrated meter, recalibrate or resize the unit, and document the before-and-after ppm reading in your job record.
- Guardsman GHE-100 electrostatic filters lose their charge gradient when humidity exceeds 60% for extended periods. Spring’s spring and fall shoulder seasons push indoor humidity into this range regularly, collapsing particle capture efficiency from 95% to roughly 60% without any visible indicator. We test charge retention with a field meter, clean the collector plates with the specified non-ionic detergent, and restore the power supply output to factory spec.
- Guardsman GBT-200 bipolar ionization units develop needle-point corrosion from Houston-area atmospheric sulfates. The ion emitters pit microscopically, reducing ion density and causing uneven distribution through the duct run - the branching network of metal passages that carries conditioned air to each room. We inspect each emitter under magnification, replace degraded points with OEM or equivalent spec parts, and verify ion density at the farthest register with a handheld counter.
Our Guardsman Air Quality & Sanitizing Process
- 1
Call intake and scheduling. A live person answers, confirms your Guardsman model if you know it, and schedules a technician arrival window. No dispatch fee, no deposit.
- 2
On-site diagnostic with camera and meters. The technician identifies the unit by serial plate, pulls camera footage of the plenum - the main air distribution box - and tests output with brand-appropriate meters: radiometer for UV, ion counter for bipolar units, ozone meter for oxidizers, charge field meter for electrostatic filters.
- 3
Written scope and price delivered before work starts. Haven Standard Clause 1: you receive a single flat price for the complete job, with line items for parts, labor, and documentation. No per-vent pricing, no add-ons after agreement.
- 4
Service execution with OEM or verified-equivalent parts. We stock Guardsman-compatible lamps, cells, and emitter points; when OEM is back-ordered, we use aftermarket parts that meet or exceed manufacturer electrical and output specifications, noted on your invoice.
- 5
Post-service testing and photo documentation. Every duct run is photographed before and after. Output meters verify restoration to spec. The photo record and test results are delivered as standard, not extra.
- 6
Written activation of the 365-Day Done Right Promise. If the work is not right, we make it right - backed in writing, not subject to manager approval.
BeforeAfterWhat Guardsman Air Quality & Sanitizing Costs in Spring

| Air purifier cell cleaning or replacement (GAP series) | $340-$680 | Cell size, fouling severity, coating condition |
| Ozone generator calibration or resize (GOS series) | $260-$520 | Metered ozone level, ductwork modifications needed |
| Electrostatic filter service (GHE series) | $220-$380 | Number of collector stages, power supply condition |
| Bipolar ionization emitter replacement (GBT series) | $300-$560 | Emitter count, corrosion extent, wiring harness condition |
| Whole-system mold or bacteria treatment | $580-$1,200 | Contamination extent, number of duct runs, post-treatment verification testing |
These are whole-system prices agreed in writing before work starts - not per-vent teaser rates that balloon on arrival. Call (346) 423-3631 for an exact quote; estimates are free.
Why Spring Homeowners Call CleanRun Air Duct Cleaning Spring for Guardsman Work
We’ve worked on Guardsman equipment in Spring since 2013, including plenty of calls near Gleannloch Farms where older construction and clay-heavy soil push surprising debris loads into return air plenums. Tomas Reyes, our owner, pulls camera footage before quoting anything - he’d rather show you what’s in the duct than describe it. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier air quality systems, so if your home has mixed-brand equipment, one crew handles it without subcontracting. The 365-Day Done Right Promise, the documented photo record, and the written price before work starts - these are standard on every job, not exceptions.
FAQs
Guardsman’s product warranty covers manufacturing defects, not service labor or consumable parts like UV lamps after the initial period.
As an independent Guardsman service provider, we perform work that preserves any remaining factory warranty by using OEM or equivalent-spec parts and following manufacturer procedures. We note serial numbers and part sources on your invoice so warranty claims remain valid. If your unit is under warranty, we can also flag whether the issue qualifies for manufacturer coverage before you pay for service. Call (346) 423-3631 and we’ll check the date code on your unit.
You receive a documented photo record of every duct run, before and after, plus meter readings where applicable - UV intensity, ion density, ozone ppm, or charge field strength.
These are concrete deliverables, not verbal assurances. The photo record shows the condition of the plenum, the register faces, and the equipment interior. For mold or bacteria treatment, we include post-treatment swab or ATP test results upon request. If a competitor’s “sanitizing” job produced no documentation, our Free Second Opinion will show you the difference - bring their estimate and we’ll put our scope and price next to it in writing.
Repair makes sense when the core components are sound and the fix restores factory output spec; replacement is the better value when multiple failure modes overlap or the unit is past two-thirds of its rated service life.
We don’t sell Guardsman equipment, so our recommendation carries no brand bias. For a GUV-100 at year eight with a failed ballast and degraded housing, we’ll tell you replacement is the economical choice. For a GAP-500 at year four with fouled cells, cleaning or cell replacement is usually the right call. The written scope includes both options when they’re close in cost, with the output data to support each path.
We stock common Guardsman OEM lamps, cells, and emitter points; when OEM is back-ordered, we use verified-equivalent aftermarket parts that meet manufacturer electrical and output specifications.
The invoice notes the source of every part. For UV lamps, we specify output wattage, base type, and rated life hours. For ion emitters, we note needle alloy and tip geometry. You can verify these specs against Guardsman’s published requirements. Haven Standard Clause 1 requires this transparency - the written price lists parts by source and spec, not vague descriptions.
UV lamps need replacement every 9,000-12,000 hours of operation, typically 12-18 months in a continuously running HVAC system; electrostatic filters need cleaning every 3-6 months; bipolar ionization and whole-home purifiers need annual inspection.
Spring’s humidity extends the biofilm risk window, so we recommend pulling the camera annually on GAP and GHE units even if performance seems normal. The debris load from clay soil and pollen in this area accelerates fouling beyond what the manufacturer bases its intervals on. Call (346) 423-3631 and we’ll put you on a schedule that matches your equipment to actual Spring conditions - no automatic rebooking, just a reminder when the hours or calendar warrant it.
