This page is for Bell homeowners who own an Abatement Technologies air filtration, HEPA, or negative air machine tied into their duct system, or who have Abatement Technologies components in their HVAC setup that need sealing, repair, or reconnection. If your system is pulling unfiltered air through a gap, or your portable unit isn’t integrating with the ductwork the way it should, we can fix that.

How Abatement Technologies Products Fail - and How We Fix Them

  • Predator 600 and 750 Series: The flexible duct connectors on these portable negative air machines harden and crack after three to five years in Bell’s dry heat, especially if they’ve been stored in unconditioned garages near the 710 corridor. We replace the damaged flex with UL-listed reinforced ducting and seal the junction with mastic, not tape, because tape fails where Bell summer temperatures climb past 95 degrees.
  • PRED1200 and larger commercial units: The sheet metal transition collars on these high-CFM machines fatigue at the screw holes where they mate with permanent ductwork. We see this in older Bell homes that were retrofitted with abatement equipment during renovation work. Our fix is to fabricate a heavier-gauge transition, seal with fiberglass-reinforced mastic, and back it with mechanical fasteners spaced at six-inch centers.
  • HEPA-Care HC500 and HC800 Series: The gasketed inlet ports on these whole-house HEPA systems lose compression over time, creating bypass leaks that defeat the filtration purpose. We replace the OEM gaskets when available, or machine equivalent closed-cell neoprene when Abatement Technologies backorders the factory part - which has happened more often since 2022.
  • Abatement Technologies PAS2400 and similar air scrubber integrations: The flex duct runs connecting these units to return plenums sag and separate at the clamp joints, especially in Bell’s older homes with cramped attics where someone stepped on the duct during a roof repair. We reroute with proper support straps every four feet and replace worm-gear clamps with permanent band clamps.
  • Legacy CAP600 and CAP1200 ceiling-mounted units: The internal duct liner on these aging systems delaminates and sheds into the airstream, which we find during camera inspection. We remove the degraded liner, repair the metal shell if corrosion is present, and reinsulate with Johns Manville Linacoustic or an equivalent airstream-rated product that won’t off-gas in Bell’s summer heat.

Our Abatement Technologies Duct Repair & Sealing Process

  1. 1
    Call and schedule. A live person answers, 24 hours a day. We ask about your Abatement Technologies model number, symptoms, and whether the unit is portable or permanently ducted.
  2. 2
    Camera inspection on arrival. Our technician runs a duct camera through the system to document every leak, crack, or separation before touching a tool. You see what we see.
  3. 3
    Diagnosis and upfront pricing. We identify whether the fix needs OEM Abatement Technologies parts - gaskets, collars, specific flex diameters - or if a quality aftermarket equivalent will perform as well and ship faster. The price is fixed before work begins.
  4. 4
    Repair and seal. We complete the mechanical repair, then seal all joints with mastic or foil-backed tape rated for the application temperature. No shortcuts on access panels or transition pieces.
  5. 5
    Post-repair camera verification and airflow test. We run the camera again to confirm the seal, then measure static pressure and airflow to verify the Abatement Technologies unit is pulling or pushing what it should.
  6. 6
    Cleanup, written guarantee, and invoice. We leave the work area clean, hand you the 90-Day Done Right Promise in writing, and charge exactly the price quoted - no surprises on the bill.

What Abatement Technologies Duct Repair & Sealing Costs in Bell

  • Flex duct replacement and sealing: $180-$340

  • Full duct section replacement with reinsulation: $380-$650
