Aeroseal Duct Cleaning from the Inside helps provide the cleanest, safest environment for you and your family through improved indoor air quality.

Introducing Aeroseal® Duct Sealing from the Inside.

Aeroseal is an industry-leading duct and air-sealing technology that eliminates leaks in your home’s heating and cooling ductwork. The unique formula uses a non-toxic, adhesive sealant that is sprayed into your ducts, finds cracks and holes in your system, and fills and seals each and every one. This combination of cutting-edge technology plus a simple and safe duct sealant formula:

  • Makes the air in your home safer to breathe by drastically reducing dust, allergens, and airborne contaminants.
    • Eliminates leaks in your ductwork, reducing energy costs.
  • Makes your system more efficient and extends its life.
  • Reduces the energy used, helping make your home a green and safe environment.

And, Aeroseal installation by All American Heating is non-invasive and takes only a few hours, with little-to-no inconvenience or clean-up needed.

Duct Sealing from the Inside®

Did you know 25-40% of the air that’s supposed to blow through your vents is escaping through cracks and holes in your air ducts? You could be wastefully heating and cooling areas like your attic, crawl space, and even behind walls.

Not only that, dust, debris, and allergens are being sucked in and blasted all over your house. Yuck! This is why your bedroom is freezing, your coffee table is always dusty, and your energy bill is through the roof.

The good news is… we make it easy to fix. Aeroseal improves lives by delivering comfort, healthy air, and substantial energy savings.

We also offer duct sanitization to help rid your home of bacteria and other contaminants that gather and grow in your home’s ductwork.

Alarms and Controls

If you live in the high country, you know that outdoor temperatures can change drastically and quickly – sometimes literally overnight.

If you have a home in the mountains that sits empty at least part of the time, or even if you live in the city and you’re away from your primary residence for any period, and the furnace or electricity goes out during the winter, you could be in for serious trouble. That’s why All American Heating recommends installing an automatic water shutoff system, a smart thermostat, or a telephone freeze alarm. This technology alerts you or a neighbor when the temperature inside reaches a predetermined low point, and before damage occurs. Automatic water shutoff systems detect leaks and turn off water valves, stopping floods before they happen. Find out more about how a freeze alarm or water shutoff system can save you from a home catastrophe.

Complete Home Air Quality Planning and Implementation

We offer a multitude of tools and services to help give you and your family the healthiest air possible. Your home is your sanctuary, and we’re here to help make life at home your best life.
