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 Atlanta: What to Know First
We provide independent Aprilaire duct repair and sealing in Atlanta, with most repairs completed in a single visit and a written flat price delivered before any work starts. A typical Aprilaire system repair runs $249 to $399 depending on the scope, and every job includes a documented photo record of every duct run. This page is for Atlanta homeowners who own Aprilaire air cleaners, humidifiers, or ventilation systems and need the ductwork connected to them sealed, repaired, or rebuilt correctly. Call (470) 495-9370 for a free written estimate.
How Aprilaire Products Fail - and How We Fix Them
- Model 5000 Electronic Air Cleaner: The integrated duct collar on this unit can separate at the mastic joint where it meets the return plenum, especially in Atlanta’s humidity cycles. We remove the collar, reseat it with fresh mastic and mechanical fasteners, and pressure-test before powering the unit back on.
- Model 600/700 Humidifier Series: The bypass duct on these humidifiers is often flex duct run across a hot attic in Sandy Springs or Decatur homes, and the inner liner collapses after 5-7 years of summer heat. We replace with insulated flex or rigid metal duct, sized to Aprilaire’s static pressure specs, and photograph the full run.
- Model 8140/8144 Ventilators: The fresh-air intake duct on these units pulls unconditioned Atlanta air through a long flex run that degrades at the termination cap. We find the break with a camera, replace the damaged section, and seal the exterior hood with proper flashing to prevent the water intrusion that caused it.
- Model 1820/1830 Dehumidifiers: The discharge duct on these whole-home units is frequently undersized by original installers, creating back-pressure that blows out duct seams in the supply plenum. We resize the discharge per Aprilaire’s CFM tables and rebuild the plenum connection with sealed takeoffs.
- Model 8920W Ventilation Control: When this controller commands a ventilator or ERV, any leak in the dedicated low-voltage control duct (used in some zoned Atlanta installations) causes the unit to short-cycle. We trace the control path, repair or replace the damaged section, and verify signal integrity at the board.
Our Aprilaire Duct Repair & Sealing Process
- 1
Written price first. We inspect the Aprilaire unit and connected ductwork, then deliver a flat price in writing before any panel comes off. Haven Standard Clause 1.
- 2
Camera diagnostics. We run a borescope through every duct run connected to the Aprilaire system. The camera doesn’t negotiate - what it shows is what we quote.
- 3
Parts decision. We stock Aprilaire-compatible collars, dampers, and transition fittings. When OEM is available and cost-effective, we use it. When a quality aftermarket part meets the same pressure and temperature specs, we explain the difference and let the homeowner decide.
- 4
Repair and seal. We rebuild or replace the damaged duct, seal all joints with mastic or foil-backed tape (never duct tape alone), and insulate where Atlanta attic heat demands it.
- 5
Pressure verification. We test static pressure at the Aprilaire unit before and after repair, with the numbers written on the job record.
- 6
Photo record and guarantee. Every duct run is photographed before and after. The full record, with the written 365-Day Done Right Promise, is delivered before we leave.

Why Atlanta Homeowners Call CleanRun Air Duct Cleaning Atlanta for Aprilaire Work
We’ve been running jobs across Atlanta since 2013, and we’ve learned that Aprilaire units are only as good as the ductwork connected to them. Our crew knows the difference between a Model 600 bypass that needs a 6-inch round duct and a Model 700 fan-powered unit that needs a dedicated return drop. The 365-Day Done Right Promise is written on every job, not mentioned and forgotten. Technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so when an Aprilaire unit is integrated with a multi-brand HVAC setup, we don’t guess at the interfaces. Every job ends with a documented photo record - inside every run, before and after - so you can verify the work without climbing into your own attic.
FAQs
No, independent duct repair does not void Aprilaire’s product warranty, provided the work does not alter the unit’s electrical or control components. As an independent Aprilaire service provider, we repair only the duct connections and airflow path, leaving the factory-sealed portions untouched. If your unit is still under Aprilaire’s original warranty, we document our work so any future factory service is not complicated. Call (470) 495-9370 if you need help confirming your warranty status.
Aftermarket parts are acceptable when they match OEM pressure, temperature, and dimensional specs. Aprilaire collars and transition fittings are standard HVAC sizes, and we source from manufacturers whose products we can verify independently. We stock both options and explain the price and spec difference before you decide. The 365-Day Done Right Promise covers either choice.
You receive a documented photo record of every duct run, before and after, as a standard deliverable on every job. We also write the pre- and post-repair static pressure readings on your job record. If the numbers don’t move, the seal didn’t happen - and under our 365-Day Done Right Promise, we make it right.
Most Aprilaire duct repairs are completed in a single visit because we stock common collars, flex duct, and mastic on every truck. If a specialized fitting is needed for an older Model 8140 or a custom plenum transition, we order it and schedule the repair within 48 hours, with no additional diagnostic fee. The written price we give at diagnosis is the price you pay at completion.
Every 3 to 5 years in Atlanta’s climate, or sooner if you notice humidity control issues, uneven airflow, or a spike in energy bills. The combination of summer attic heat and winter heating cycles degrades flex duct and mastic joints faster than in milder climates. We offer a free second opinion on any written estimate if another company has recommended work.
