Best Duct Sealing & Aeroseal Pros in Rock Hill, SC
What to look for in Duct Sealing in Rock Hill
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 long does a typical Rock Hill "Duct Cleaning" visit take and what should a homeowner expect?
- 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.
- What should homeowners expect when technicians perform duct sealing during a duct cleaning visit?
- Expect a separate assessment and a short pressure or smoke test before sealing begins. Technicians will identify leaks, explain proposed sealants or mechanical repairs, and estimate added time and materials. Duct sealing often extends the visit by one to three hours. Ask for before-and-after photos and a written description of sealed areas.
- How can a homeowner tell if a provider is experienced with mold remediation or sanitizing in Rock Hill?
- Look for technicians who explain moisture sources, provide moisture or humidity measurements, and reference specific sanitizing products and application methods. Request references or recent job photos showing mold removal and post-treatment testing. Providers should also discuss follow-up HVAC or moisture-control recommendations.
- How long should a Rock Hill homeowner wait for a written scope and photos after an inspection?
- Homeowners should expect a written scope of work, with cost estimates and photos, within one to three business days after inspection. The scope should list inspected components, recommended actions, and any warranty or follow-up terms. Ask providers to include before-and-after imaging for sealed or remediated areas.
