What is Aeroseal duct sealing?

Aeroseal is an aerosolized sealant blown through pressurized ductwork that seals leaks from the inside and reports a measured before/after leakage number. It's distinct from manual sealing with mastic or metal tape, which is applied by hand at accessible joints.

How much can duct sealing save?

Leaky ducts waste roughly 20–30% of heating and cooling energy (ENERGY STAR), so sealing can meaningfully cut bills and fix hot-and-cold rooms. The payback is faster in long-cooling-season climates. Many utilities (e.g. AEP Texas Standard Offer programs) also offer rebates — confirm eligibility before assuming a credit.

When is duct sealing recommended after a cleaning in Corpus Christi homes?

Duct sealing is recommended when leaks, corrosion, or disconnected joints are found during inspection. Coastal salt air can accelerate seam corrosion, creating efficiency losses and dust ingress. Request a pressure test or visual documentation of leaks and a written repair recommendation before agreeing to sealing or repairs.

What evidence should a contractor provide after duct cleaning and mold remediation?

Ask for before‑and‑after photos, a written scope of work, and a description of equipment used, such as truck‑mounted vacuums and air scrubbers. For mold work, request product labels and application method. For sealing, request photos of repaired seams and any pressure test results. Keep all reports for future resale disclosures.

Are permits required for duct repairs or sealing in Corpus Christi?

Permits are not typically required solely for duct cleaning, but major HVAC alterations or system replacements may trigger city permit requirements. Consult the local building department when work involves substantial modifications, and ask the contractor whether their recommended repairs will require a permit or licensed HVAC trade involvement.

What does duct cleaning service typically run in Corpus Christi, TX?

Aeroseal aerosol duct sealing typically runs $1,050–$2,450 in Corpus Christi, Texas. See the Duct Cleaning pricing table on this page for the full per-service breakdown.

Best Duct Sealing & Aeroseal Pros in Corpus Christi, TX

Last reviewed June 14, 2026

What to look for in Duct Sealing in Corpus Christi

Duct sealing is measured, not sprayed-and-claimed — leaky ducts waste 20–30% of conditioned air (ENERGY STAR). The pros worth hiring report a before/after leakage number: Aeroseal aerosol sealing logs it automatically, and manual sealers should blower-door test. We weight Aeroseal-certified and test-capable providers above generic "we seal ducts."

Duct sealing specialization. Provider lists Aeroseal or manual (mastic/aerosol) duct sealing as a distinct service with method detail — not a one-line claim.
Google rating. Duct sealing is a higher-ticket job, so a strong rating floor with outcome-specific reviews is the trust threshold.
Aeroseal / leakage-test capability. Aeroseal certification or duct-leakage testing (Duct Blaster, blower door) signals verifiable, measured results rather than visual cleanup.

Verify before you book

Active Aeroseal dealer status (manufacturer registry is the verification step) — we accept self-claimed.
Whether a before/after leakage test was actually run — ask for the numbers.
Utility-rebate eligibility (e.g. AEP Texas Standard Offer) — confirm with the provider and your utility before assuming a credit.
