In a large Covington home, leaky ductwork doesn’t just waste energy — it leaves whole wings warm and humid while the AC runs overtime. The more square footage and duct runs you have, the more leaks add up. Tegridy Air inspects, seals, and repairs ductwork across Covington and St. Tammany Parish. Call (504) 414-8655. Family-owned, 30+ years of combined experience.

Signs of duct trouble in Covington homes

  • Whole rooms or an upstairs that never matches the thermostat.
  • High bills despite an AC (or two) running constantly.
  • Dust and a humid, stuffy feel even with the system on.
  • Ducts sweating in hot attics, dripping onto insulation.
  • Long flex-duct runs that have sagged, kinked, or pulled apart.

Why bigger homes leak more

Covington’s larger floor plans mean long duct runs through hot attics — and the longer the run, the more joints there are to dry out and leak. Heat breaks down old mastic and tape; humidity condenses on uninsulated ducts and breeds mold. In a sprawling or two-story home, even modest leakage on each branch adds up to a lot of cooled air dumped into the attic. Sealing and insulating those runs is one of the highest-return improvements available here.

How we fix it

We inspect the entire duct system — every branch and both systems if you have two — find leaks and disconnects, and seal joints with mastic and metal tape, never cloth tape that fails in the heat. We re-secure sagging runs, replace damaged sections, and insulate ducts that sweat.

Duct repair pricing in Covington

  • Duct inspection / leakage check: $80–$150
  • Targeted sealing & minor repairs: $350–$900
  • Whole-home or multi-system re-runs: quoted after inspection

You approve a written price first. On a large home, sealed ducts can take a real bite out of the summer bill and pay back quickly.

Why Covington homeowners choose Tegridy Air

  • We assess the whole duct system, not just the AC unit.
  • Sealing and insulation built for Northshore heat and humidity.
  • Up-front pricing, financing, and maintenance plans.
  • Family-owned, local, reachable 24/7.

Duct repair FAQs

How do I know my ducts leak?

Uneven rooms, high bills, and dust are the signs; an inspection confirms it and locates the leaks.

Seal or replace?

Most homes need sealing and insulation; we replace only crushed, undersized, or failed sections.

Is it worth it on a big home?

Especially so — more duct means more potential leakage and bigger savings from sealing it.

Will it help humidity and dust?

Yes — sealing stops humid attic air, dust, and moisture from being pulled into the system.
