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 do I find a Miami specialist who handles both duct cleaning and duct sealing?

Answer: Look for providers who document both rotary‑brush agitation and aerosol or mastic sealing methods. A clear scope should list agitation method, HEPA/négative‑air evacuation, and post‑seal leak testing. Verify references or reviews showing combined jobs in neighborhoods like Coral Gables or South Beach. Confirm the contractor holds any DBPR license needed for sealing or HVAC repairs.

How long does a typical duct cleaning visit disrupt household HVAC use in Miami condos or single‑family homes?

Answer: Most residential duct cleanings limit direct disruption to equipment access and register work for two to six hours. Systems often run with restricted operation during negative‑air setups. For complex jobs involving sealing, repairs, or mold remediation, expect multiple work phases and possible multi‑day scheduling. Confirm expected downtime in the written estimate.

Best Duct Sealing & Aeroseal Pros in Miami, FL

Last reviewed June 16, 2026

What to look for in Duct Sealing in Miami

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.
