Best Duct Sealing & Aeroseal Pros in Summerville, SC
What to look for in Duct Sealing in Summerville
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.

- 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 identify a qualified contractor for duct sealing as part of a duct cleaning in Summerville?
- Look for contractors who test ducts before and after sealing, and who can show pressure-test or leakage-reduction results. Seek providers that use mastic or UL-rated tapes rather than simple foil tape. Ask for evidence of NADCA or IICRC training, and request references for recent duct-sealing jobs in similar homes.
- How can property managers verify scope and acceptance criteria for large duct cleaning contracts in Summerville?
- Require a written scope, testing methods, and acceptance criteria like particulate counts or visual inspections. Specify who pays permit fees and who inspects results. Ask for technician certifications, equipment lists, and a cleanup plan. Include a payment holdback until specified acceptance checks are completed.
