Yes. Aeroseal works on flex duct, sheet metal, and fiberboard — the three types found in virtually every Arizona home. The process injects aerosolized polymer particles under slight pressure; they bypass any open area and adhere only at leak points. The only ducts we can’t seal are those with large physical gaps (> ¼”) or collapsed sections — those need mechanical repair first, and we’ll tell you upfront.

Aeroseal duct sealing typically runs $1,500–$2,500 depending on home size. Attic insulation to R-49 runs $1,800–$3,500. After federal and utility incentives, net cost is usually 40–60% lower. Typical simple payback: 3–5 years on duct sealing, 4–7 years on insulation. Combined with solar, the reduced load often cuts payback on the whole system to under 7 years.

No. Aeroseal is an EPA-recognized indoor air quality improvement measure. The polymer (same family used in surgical sutures) is non-toxic, non-flammable, and does not interact with HVAC equipment. Your equipment warranty is unaffected. We carry $2M in liability insurance and a 10-year warranty on the seal itself.

You can, but it’s not optimal. Leaky ducts move conditioned air into the attic space, where it’s immediately lost through the very insulation you just paid to install. We recommend sealing first so your insulation investment actually performs. That said, if your ducts are already tight (we’ll test), insulation-only is a great standalone upgrade.

Aeroseal sealing takes 2–4 hours. You can stay home — the only precaution is keeping pets and children away from the work area during the process. Attic insulation takes 3–6 hours and also doesn’t require you to vacate. We protect all attic access areas and clean up completely before we leave.
