Aeroseal Duct Sealing

The average duct system leaks a shocking share of the air you've paid to heat or cool — into the attic, the walls, the crawl space. Aeroseal seals those leaks from the inside, and Heating & Cooling Two is your Aeroseal contractor for the Twin Cities metro. Family-owned since 1980. Call 763-210-4646.

The process

How Aeroseal works

  1. 1

    We measure your leakage.

    A before-test shows exactly how much air your ducts are losing.

  2. 2

    Sealant seals from the inside.

    Aerosolized sealant travels through the ducts and bonds at every leak point — even the ones buried in walls no one can reach.

  3. 3

    You see the proof.

    An after-test shows the measured improvement, in numbers, before we leave.

FAQ

Duct sealing questions, answered

Is Aeroseal safe?

Yes — the sealant is applied from inside the ducts and has been used in homes, schools, and hospitals for decades.

How much duct leakage is normal?

Most homes we test leak far more than their owners expect — that's why we measure before and after, so you see real numbers, not promises.

Will it fix my hot and cold rooms?

If leaky ducts are the cause, yes — sealed ducts deliver air where it was designed to go. If it's a zoning or balance issue instead, we'll tell you that.
