Best Duct Sealing & Aeroseal Pros in Fort Collins, CO
What to look for in Duct Sealing in Fort Collins
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.

Which Fort Collins neighborhoods see the most seasonal duct issues — and what should homeowners ask?
- 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 Fort Collins contractor who can both clean ducts and perform duct sealing?
- Look for providers who list duct sealing as a capability and who show Aeroseal or equivalent certification. Ask for before-and-after leakage numbers, blower-door or pressure-test methods, and whether sealing is bundled with the cleaning. Request documentation of the sealing method and a warranty description (advertised).
- Will duct sealing disturb existing HVAC equipment or require permits in Fort Collins?
- Minor sealing work usually does not require city permits, but larger modifications or equipment access might. Ask the contractor whether permits are needed in the specific Fort Collins jurisdiction and whether sealing will require access panels or temporary system shutdowns. Request a written plan that notes permit responsibilities.
