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.

AfterAprilaire Duct Repair & Sealing in Cumming: What to Know First
We provide independent Aprilaire duct repair and sealing in Cumming with written prices delivered before any work starts, and most residential jobs are completed in a single visit. Our crews carry OEM and quality aftermarket parts for the Aprilaire lines most common in Forsyth County homes, including the 8140 and 8144 series ventilators and the 1820/1830 dehumidifier lines that tie directly into trunk ductwork.
This page is for homeowners who own an Aprilaire product and have noticed uneven airflow, humidity that won’t drop, or a ventilator that runs but doesn’t move air the way it used to. If you’re seeing those symptoms in Cumming, Vickery, or anywhere along Bethelview Road, we can diagnose it and show you exactly what’s wrong before you decide on a repair. Call (678) 693-5322 for a free estimate.
How Aprilaire Products Fail - and How We Fix Them
- Aprilaire 8140/8145 Whole-Home Ventilator - cracked flex duct collars. The plastic collar where the ventilator meets the main return duct gets brittle after 8-12 years in Cumming’s attic heat. We’ve replaced dozens of these in two-story homes near Vickery where the unit sits above the master bedroom. The fix is a metal transition collar with mastic sealant, not another plastic part that’ll crack again.
- Aprilaire 1820/1830 Dehumidifier - disconnected drain-to-duct connections. These units have a short flex run from the dehumidifier to the supply plenum that sags over time, collecting condensate and leaking into the duct insulation. In Cumming’s humid summers, that wet insulation becomes a mold vector. We replace the sagging flex with a pitched hard-pipe drain and seal the plenum penetration with foil tape and mastic.
- Aprilaire 5000 Air Cleaner - bypass damper seal failure. The foam gasket on the bypass damper degrades, letting unfiltered air leak past the media cabinet. Homeowners think the filter’s dirty when it’s actually the damper seal. We replace the gasket with OEM-spec closed-cell foam and test the seal with a smoke pencil.
- Aprilaire Zoned Comfort Control - duct pressure imbalance from leaking zone dampers. The motorized dampers in Aprilaire zone systems can stick partially open, overpressurizing one zone and starving another. We see this in newer Cumming builds with open floor plans where the system was zoned after the fact. The repair is damper recalibration or replacement, plus a static pressure test to confirm the fix.
- Aprilaire 8910 Home Automation - smart thermostat wiring faults in humid crawl spaces. The low-voltage wiring runs to Aprilaire’s communicating thermostats can corrode in Cumming’s clay-heavy crawl spaces, causing the system to misread duct temperature and overcool. We rerun wiring in sealed conduit and seal any duct penetrations with fire-rated caulk.
Our Aprilaire Duct Repair & Sealing Process
- 1
Written estimate first. We inspect the Aprilaire unit and its duct connections, then deliver a written price before any panel comes off. Haven Standard Clause 1.
- 2
Photo documentation. Our tech photographs every duct run, plenum connection, and penetration before touching a fitting. Tomas Reyes put this in place back in 2013: “The camera doesn’t have an opinion - it just shows you what’s in there.”
- 3
Parts decision with the homeowner. We stock OEM Aprilaire collars, gaskets, and dampers, plus quality aftermarket alternatives where the OEM part has a known design flaw. We explain the trade-off and let you choose.
- 4
Repair and seal. We replace or repair the failed component, seal with mastic or foil tape per the application, and verify with a smoke test or static pressure reading.
- 5
Post-repair photo record and test. After photos go into your job record, we run the Aprilaire unit through a full cycle and confirm operation at the thermostat.
- 6
Written guarantee delivered. The 365-Day Done Right Promise goes in your hand before we leave. Haven Standard Clause 5.

Why Cumming Homeowners Call CleanRun Air Duct Cleaning Cumming for Aprilaire Work
We’ve been running Aprilaire jobs across Cumming since 2013, and we’ve learned which model lines show up in which neighborhoods. The two-story plans in Vickery tend to have 8140 ventilators with collar fatigue. The newer builds off Bethelview Road often have 1820 dehumidifiers with drain line issues from rushed initial installs.
Our techs carry parts for Lennox, Trane, and Carrier systems too, so if your Aprilaire is integrated with another brand’s air handler, we don’t need a second call. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is in writing on every job, not just stated on the website. And the photo record - before and after every duct run - is included as standard, not an upsell.
FAQs
No, if the work is performed by a qualified technician using manufacturer-specified parts and methods. As an independent Aprilaire service provider, we use OEM or equivalent components and document the repair, which satisfies warranty requirements. Call (678) 693-5322 if you need a repair record for a warranty claim.
Sealing handles leaks at joints, collars, and penetrations where the duct material itself is sound. Replacement is needed when flex duct is crushed, metal duct is corroded through, or insulation is saturated and delaminated. We photograph the condition and show you which category you’re in before quoting either option.
We stock the common failure parts for 8140, 8145, 1820, and 1830 series units on our trucks. Less common items like zone control boards typically arrive next business day from our Atlanta distributor. We’ll tell you exactly what’s in stock before you approve the repair.
We test with a smoke pencil at every sealed joint and provide a post-repair static pressure reading compared to your pre-repair baseline. Both numbers go into your documented photo record. If the pressure hasn’t improved, we keep working until it does - that’s Haven Standard Clause 5.
Repair when the unit functions correctly but the duct connection has failed - cracked collar, loose seal, sagging flex. Replace when the unit itself has electrical or mechanical failure and is past 12-15 years of service life. We give you both numbers in writing so you can decide on evidence, not pressure.
