Best Duct Sealing & Aeroseal Pros in Hoover, AL
What to look for in Duct Sealing in Hoover
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.

How often should Hoover homeowners get ducts cleaned, and what should they ask contractors?
- 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.
- Is a city or county permit required for duct sealing or major duct modifications in Hoover?
- Permits depend on scope. Small duct sealing or internal duct repairs usually do not need a building permit, but replacing major trunk runs or altering conditioned-space penetrations can trigger the 2021 IECC permit requirements enforced in Alabama. Ask the contractor whether the proposed work will change duct layout or affect conditioned space, and request that they confirm permit needs with Hoover building inspections before starting.
- How do I find a duct-sealing specialist in Hoover who can document leakage reductions?
- Look for contractors who offer pre- and post-seal diagnostic testing such as duct-blaster or flow measurements. Ask for video or pressure-test results and a written scope that lists sealing locations. Verify that technicians show how sealing improves airflow or efficiency for the specific home, whether in Hoover Village, Greensprings, or older central neighborhoods.
- What visual or test evidence should a contractor provide after completing duct cleaning or sealing in Hoover?
- Request before-and-after camera footage of the duct interior and a written checklist showing cleaned components. For sealing, ask for pressure-test data or a clear description of sealed penetrations. Photographic and video evidence helps homeowners verify work and supports warranty or follow-up service discussions.
