How Aprilaire Products Fail – and How We Fix Them

Aprilaire builds solid air quality equipment, but the ductwork attached to it takes a beating in North Texas. Here’s what we actually find when we open up systems in Fort Worth homes.

• Aprilaire Media Filter Cabinets with Leaky Return Plenums. The Aprilaire 5000 and 2200 series filter cabinets are common in Fort Worth homes, and the cabinet-to-duct connection is where we find trouble. The weight of a loaded media filter pulls on the sheet metal over time, opening gaps at the return plenum. Your Aprilaire filter is catching particles, but unconditioned attic air is slipping in around it. We seal those joints with mastic and re-hang the cabinet so it’s supported properly. The filter can do its job again.
• Aprilaire Humidifier Bypass Ducts Feeding Moisture Into Supply Trunks. Homes with an Aprilaire 700 or 600 whole-home humidifier have a round bypass duct that taps into the supply trunk. Fort Worth’s clay soil shifts seasonally, and that small bypass line is often the first connection to crack. The result is a humid pocket inside the supply duct, which turns dust into paste and rusts the sheet metal from the inside. We reseal that tap and check the damper position while we’re there.
• Aprilaire Zone Dampers With Worn Actuator Seals. If your Fort Worth house has an Aprilaire zone control board with dampers in the duct runs, those damper shafts wear where they pass through the duct wall. A quarter-inch gap around a damper shaft is enough to lose conditioned air into a hot attic. We remove the damper assembly, clean the mating surfaces, and seal with a flexible mastic that holds up to Fort Worth’s 140-degree attic summers.
• Aprilaire Ventilation Systems With Unsealed Outdoor Air Intakes. The Aprilaire 8100 energy recovery ventilator brings outside air into the return side of your system. When the intake penetration through the roof or wall isn’t sealed correctly, that duct pulls in whatever the Texas wind carries. We reseal those penetrations and verify the intake is actually bringing in the air volume Aprilaire designed it for, not a dusty shortcut from your soffit.
• Faded Mastic on Original 1990s and 2000s Installations. Fort Worth homes built when Aprilaire was first widely installed in the area now have mastic that’s chalked and cracked. We reapply a reinforced mastic at every visible seam on the trunk and branch lines. This is the most common Aprilaire repair we do: the equipment is fine, but the sealant gave up years ago.

Our Aprilaire Duct Sealing Process

Here’s how a typical Aprilaire duct sealing job runs at Hollis Air Duct Fort Worth, from the first call to the final walkthrough.

1. 1
   Call and schedule. You talk to a live person, not a voicemail tree. We set a window and we hit it.
2. 2
   On-site inspection. A background-checked, uniformed technician walks the system, opens the filter cabinet or humidifier access, and notes exactly which joints, taps, and penetrations are leaking.
3. 3
   Parts decision. We prefer OEM Aprilaire seals, damper gaskets, and components when they’re available and the price is fair. When an aftermarket part is equal or better in quality, we tell you before we use it and explain why. No surprises.
4. 4
   Written quote. You get one flat price for the entire Aprilaire system, in writing, before any work begins. That number does not move at the door.
5. 5
   The sealing work. We use mastic, UL 181-rated tape, and where needed, Aeroseal-style aerosol sealing for hard-to-reach branch runs. Equipment used on Aprilaire jobs includes Rotobrush and Nikro systems where cleaning is required first.
6. 6
   Test and guarantee. We verify static pressure and airflow before and after. Every Aprilaire duct sealing job is covered by the 365-Day Done Right Promise. If the seal fails within a year, we come back at no charge and do it again right.
