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.
Honeywell Duct Repair & Sealing in New Braunfels: What to Know First
CleanRun Air Duct Cleaning New Braunfels provides independent Honeywell duct repair and sealing for homeowners in New Braunfels and nearby areas. Most Honeywell duct jobs we handle are completed in a single scheduled visit, with a written price delivered before any work starts under Haven Standard Clause 1. We are not affiliated with or authorized by Honeywell; we service Honeywell systems as an independent provider using OEM or quality aftermarket parts.
This page is for homeowners running Honeywell whole-home ventilators, electronic air cleaners, or integrated zoning panels who have noticed uneven airflow, whistling at registers, or rising utility bills. If your Honeywell equipment is working but your ducts are not delivering what it produces, the problem is usually in the ductwork, not the unit. Call (830) 549-6847 for a free estimate with a written price before we start.
How Honeywell Products Fail - and How We Fix Them
- TrueDRY DR90/DR120 dehumidifier duct collars crack at the plastic flange. The DR series mounts inline with your return duct, and the collar flange sees constant thermal cycling in New Braunfels attics where summer temperatures exceed 140°F. We replace with a metal transition collar and seal with mastic, not tape, because tape adhesive degrades in that heat. The repair takes about 90 minutes and is documented with before and after photos of the collar joint.
- Fresh Air Ventilation System (FAVS) dampers stick closed due to debris buildup on the blade edge. Honeywell’s FAVS line uses a motorized damper that opens on a call for ventilation; when the blade edge cakes with attic dust, the motor strains and the damper fails to seal or fails to open. We remove the damper assembly, clean the blade and frame with negative-pressure extraction (suction that pulls debris out rather than pushing it in), then reseal the duct collar. If the motor is stripped, we source the exact Honeywell replacement actuator rather than substituting a generic.
- ZonePerfect and RedLINK zoning panels create pressure imbalances when duct runs are undersized. Honeywell zoning works by opening and closing dampers to direct air; when the ductwork was not designed for zoning, the static pressure spikes and flex duct blows apart at the takeoff. We see this in Canyon Lake area homes built 2015-2019 where builders added zoning without resizing ducts. Our fix is a pressure relief damper or duct run enlargement, calculated with a manometer reading, not guesswork.
- Electronic Air Cleaner (F300, F50) cells leak voltage when duct seams open near the cell cabinet. The cell sits in a metal channel that must be grounded through the duct; if a seam opens or a screw backs out, the ground path weakens and the cell throws arcing faults. We repair the duct seam with sheet metal screws and mastic, then verify ground continuity with a multimeter. This is not a cell replacement; it is a duct grounding repair, and it costs about half what a new cell runs.
- Whole-house humidifier bypass ducts (HE100, HE300 series) rot at the humidifier port. The 6-inch round bypass duct on Honeywell flow-through humidifiers is often flex duct in New Braunfels installations, and the constant moisture at the humidifier port degrades the inner liner. We replace with insulated flex or hard pipe, depending on attic access, and seal the humidifier cabinet interface with a gasketed collar. The HE300 in particular needs this every 8-10 years in our climate.
Our Honeywell Duct Repair & Sealing Process

- 1
Inspection with photo documentation. We access the duct system at the plenum (the main distribution box) and at each register, photographing the interior of every run with a duct camera. Tomas Reyes started this practice in 2013; we still show the photo first, explain what you’re looking at, then talk about what happens next.
- 2
Written scope and price. Before any panel comes off, we deliver a written price under Haven Standard Clause 1. The scope names the Honeywell component involved, the duct repair required, and the parts source (OEM Honeywell or quality aftermarket).
- 3
Parts decision and procurement. For Honeywell-specific components like FAVS actuators or DR90 collars, we verify availability before starting. If OEM is back-ordered, we present the aftermarket equivalent with manufacturer spec sheets so you can verify the match.
- 4
Repair and sealing. We execute the duct repair using mastic sealant, metal screws, and replacement flex or hard pipe as specified. All seams are sealed to prevent leakage; insulation is restored or upgraded where removed.
- 5
Pressure test and photo record delivery. We verify airflow balance with a manometer and deliver the complete photo record, before and after, as a standard job document. The 365-Day Done Right Promise is activated in writing.
- 6
Cleanup and scheduling. Technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. We leave no debris; we do leave a written warranty.

AfterWhat Honeywell Duct Repair & Sealing Costs in New Braunfels
These are the whole-system price ranges we have written for Honeywell duct repair and sealing jobs in New Braunfels since 2013. Every price is agreed before work starts; there is no per-vent add-on.
- Single-point flex duct repair (one run, one register): $280-$420
- Honeywell dehumidifier or humidifier collar replacement and reseal: $340-$520
- FAVS damper removal, cleaning, and reseal with actuator test: $380-$560
- Zone pressure relief or duct run enlargement (one zone): $520-$780
- Full duct sealing with mastic (average 2,200 sq ft home): $1,800-$2,600
What moves the price: attic accessibility, whether the duct is flex or hard pipe, and whether the Honeywell component must be removed to access the duct. Homes in the Gruene Historic District with original 1980s flex duct often require more extensive replacement than newer construction in Veramendi.

Why New Braunfels Homeowners Call CleanRun Air Duct Cleaning New Braunfels for Honeywell Work

We have served 52,000+ homes since 2013, every one with a written price before work started and a documented photo record when the crew left. The 365-Day Done Right Promise is not a policy subject to manager approval; it is a written guarantee on every job. Our technicians carry Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman equipment - brands you can verify independently.
We also service Lennox, Trane, and Carrier systems, which matters when your Honeywell zoning panel is paired with a non-Honeywell air handler and the failure is at the interface. Our Free Second Opinion on any written estimate means you can bring a competitor’s quote; we will put our number next to it in writing. All calls are answered by a live person, 24/7.
FAQs
No, independent duct repair does not void Honeywell’s product warranty, which covers the unit itself, not the attached ductwork. Honeywell’s warranty terms exclude consequential damage from improper installation, so we document our work with photos to show that duct modifications were performed to manufacturer-compatible standards. If you have a remaining parts warranty on a TrueDRY or FAVS unit, we use OEM parts to preserve coverage. Call (830) 549-6847 if you want us to review your warranty documents before quoting.
Most Honeywell duct interface parts - collars, actuators, gaskets - are available within 2-3 business days through our suppliers. For older F50 and F300 series components, we sometimes source refurbished OEM or quality aftermarket equivalents with equivalent specifications. We verify parts availability before writing the price, so you know the timeline before agreeing to the job. Call (830) 549-6847 for current lead times on your specific model.
Repair the ducts if the Honeywell unit is under 12 years old and functioning; replace the unit if it has failed electrically and the duct repair cost exceeds 40% of a new system. We have seen FAVS dampers replaced unnecessarily when the real problem was a $340 duct collar leak. Our inspection includes a functional test of the Honeywell component so you are not paying for equipment you do not need. Call (830) 549-6847 for a free second opinion on any replacement recommendation.
You receive a documented photo record of every duct run, before and after, as a standard deliverable on every CleanRun job. We also perform a pressure test with a manometer and record the reading. If the after photos do not show sealed seams and the pressure test does not show reduced leakage, the 365-Day Done Right Promise applies. This is not a policy; it is a written guarantee. Call (830) 549-6847 to schedule an inspection and see sample documentation.
We do not offer coupon pricing because we do not perform coupon-grade work. A $79 duct cleaning special typically involves a shop vacuum at the register, no camera inspection, and no photo record. Our pricing reflects documented work with professional equipment: Rotobrush and Nikro negative-pressure systems, Abatement Technologies HEPA filtration, and a written scope. We will provide a Free Second Opinion on any competitor’s written estimate so you can compare scope, not just headline price. Call (830) 549-6847 for an honest written quote.
