Best Duct Sealing & Aeroseal Pros in Austin, TX
What to look for in Duct Sealing in Austin
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.

Why Austin's summer heat makes "Duct Cleaning" essential in Austin, Texas
Austin's long, hot summers (May–September) raise indoor dust and allergens and put HVAC ducts under heavy strain. Many homeowners turn to best duct cleaning companies in Austin, TX to restore airflow and improve AC efficiency. Older cottages in Hyde Park and bungalows near South Congress commonly collect lint and pollen during peak cooling season.
How long should Austin homeowners expect a professional "Duct Cleaning" visit to take?
- 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.
- How can homeowners confirm a provider will recommend duct sealing after cleaning?
- Ask if the provider performs pre- and post-cleaning camera inspections and pressure testing. Providers who offer duct sealing typically include a visual inspection and will report on leaks. Look for mentions of negative-air extraction and targeted recommendations in the job scope. Request a written scope that separates cleaning from sealing to compare quotes clearly.
- What signs after a winter freeze should prompt an emergency duct inspection in Austin?
- Sudden airflow loss, new musty odors, or visible attic dust in registers warrant immediate inspection. Winter freeze events can crack seams and draw attic contaminants into ducts. Providers can perform camera inspection and negative-air extraction to find and remove contamination. If repairs are recommended, confirm whether City of Austin permits or Austin Energy inspections apply.
- How do camera inspections and pressure testing determine the need for duct sealing in Austin homes?
- Camera inspections locate debris and physical breaches, while pressure testing quantifies leak rates and loss. Combined results show whether sealing will noticeably improve airflow or efficiency. If testing reveals significant leakage, request a written repair plan that lists methods, materials, and whether sealing requires City of Austin permits for associated HVAC work.
- Typical duct cleaning pricing in Austin, TX: what should I budget?
- Aeroseal aerosol duct sealing typically runs $1,200–$2,750 in Austin, Texas. See the Duct Cleaning pricing table on this page for the full per-service breakdown.
