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 Duct Repair & Sealing in New Braunfels: What to Know First
We provide independent Aprilaire duct repair and sealing in New Braunfels, with most repairs completed in a single visit and a written price delivered before any work begins. As an independent Aprilaire service provider, we service all Aprilaire lines with OEM or quality aftermarket parts, and every job ends with a documented photo record of the work. If you own an Aprilaire system and have noticed uneven temperatures, rising energy bills, or whistling from the registers, the issue is often in the ductwork, not the unit itself. Call (830) 549-6847 for a free estimate with a written price.
How Aprilaire Products Fail - and How We Fix Them
- Aprilaire 800 Steam Humidifier - leaking supply duct at the tap. The 800’s high-output steam generation creates thermal cycling that loosens the saddle tap on galvanized supply ducts over time. In New Braunfels, where summer attic temperatures exceed 140°F, the expansion and contraction accelerates. We remove the compromised tap section, seal with mastic and a reinforced collar, and photograph the repair before closing.
- Aprilaire 600 Automatic Humidifier - bypass duct collar separation. The 6-inch round bypass duct on the 600 series relies on a sheet-metal collar that can pull away from the plenum when the humidistat cycles frequently. We find this often in homes near the Gruene Historic District with original flex duct from the late eighties. Our fix: reseat the collar with sheet-metal screws, seal with UL-181 mastic, and pressure-test the joint.
- Aprilaire 5000 Electronic Air Cleaner - gasket degradation causing return duct leakage. The 5000’s cabinet gaskets harden after 6-10 years in Texas heat, allowing unfiltered air to bypass the unit through gaps in the return ductwork. We replace the gaskets where needed, but more importantly we seal the return plenum and transitions with mastic to restore the negative-pressure balance the 5000 depends on.
- Aprilaire Zoned Comfort Control - duct pressure imbalances from damper failure. When Aprilaire zone dampers stick partially open or closed, the duct system pressurizes or starves individual runs. This strains flex duct connections at the plenum. We diagnose damper operation first, then repair the duct damage - typically separated flex-to-plenum connections - rather than masking the symptom with more airflow.
- Aprilaire 1850/1870 Dehumidifier - collapsed flex duct on the dedicated return. The dedicated return for whole-house dehumidifiers runs at higher static pressure than standard HVAC returns. In New Braunfels, we regularly see spring failures in the flex duct support wire where the 1850’s return makes a sharp elbow in tight attic spaces. We replace with insulated flex rated for the application, support every 4 feet per IRC, and seal all joints with mastic.
Our Aprilaire Duct Repair & Sealing Process

- 1
Inspection with photo documentation. We access the attic or crawl space and photograph every duct run, plenum connection, and register boot. Tomas Reyes started this practice back in 2013, and we still do it on every job.
- 2
Written scope and price. Before any panel comes off, we deliver a written price with line-item scope. Haven Standard Clause 1: no work begins without a signed written price.
- 3
Parts decision: OEM or quality aftermarket. For Aprilaire-specific components like humidifier collars or zone damper housings, we use OEM when available. For general duct repair - mastic, flex duct, sheet metal - we use trade-recognized brands including Honeywell and Guardsman materials that meet or exceed OEM spec.
- 4
Repair and seal. We execute the repair, seal all joints with mastic or foil tape per application, and verify register airflow with a digital anemometer.
- 5
Pressure test and photo record delivery. We pressurize the system and check for leaks with a smoke pencil or thermal camera. Then we deliver the before-and-after photo record as part of the standard job file.
- 6
Written guarantee. Every repair is backed by our 365-Day Done Right Promise, documented in writing before we leave.

FAQs
No, duct repairs performed by an independent service provider do not void the Aprilaire unit warranty, provided the work does not alter the unit’s electrical or control components. We document our scope with photos to prove the repair was ductwork-only. If your Aprilaire is still under warranty, we note the serial number and repair location in our job record so you have backup. Call (830) 549-6847 if you need help determining warranty status.
OEM parts matter for the Aprilaire unit itself - control boards, sensors, damper motors. For ductwork repairs, the critical spec is pressure rating and UL listing, not the brand on the box. We use Guardsman and Honeywell materials that meet the same standards, and we explain the choice in writing before ordering. If an OEM collar or adapter is required for proper fit, we source it and show you the part before installation.
Replace if the ductwork is galvanized steel with widespread corrosion, flex duct with multiple punctures or collapsed sections, or if your system is losing more than 20% airflow to leakage. Repair if the damage is localized to a few joints, a single humidifier tap, or a zone damper transition. We photograph the full system and show you the extent before recommending either path. Our written estimate includes both options when both are viable.
We schedule Aprilaire duct repairs within a few business days, with emergency scheduling available for active leaks or detached ducts causing system shutdown. Every appointment window is honest - we do not overbook. Call (830) 549-6847 for the next available slot.
You receive a documented photo record of every duct run we accessed, before and after, plus pressure test results where applicable. Tomas Reyes has held to “Show the photo first. Explain what you’re looking at. Then talk about what happens next.” since our first job in 2013. The photo record is included as a standard deliverable on every visit, not an upgrade.
