Up to 30 percent of the air moving through a typical home’s duct system never reaches the rooms it was meant to serve. It escapes through gaps at joints, cracked seams, disconnected sections, and pinhole leaks hidden inside walls, ceilings, and crawlspaces. In Skokie homes, where basements, attics, and finished additions often carry ductwork through hard-to-reach spaces, those losses add up to uneven temperatures, higher energy bills, and rooms that never quite feel comfortable. Aeroseal duct sealing addresses this problem from the inside, and All Temp Heating & Air Conditioning brings this technology to homeowners across Skokie and the surrounding region.
How Aeroseal Duct Sealing Actually Works
Traditional duct sealing depends on a technician physically reaching each connection point and applying mastic or tape by hand. That approach works only where hands can go, and most of a home’s ductwork runs behind drywall, above ceilings, or deep within joist bays where no one can reach. Aeroseal takes a completely different path. Rather than sealing from the outside, it seals from the inside using an aerosolized polymer that is pushed through the duct system under gentle pressure.
The process begins by temporarily blocking the registers and grilles throughout your home. We then connect specialized equipment to the duct system and pressurize it. As air moves through the ducts, it carries microscopic sealant particles suspended in the airstream. When those particles reach a leak, the change in pressure and airflow causes them to accumulate at the edges of the gap, gradually building a durable seal. Larger openings close first, followed by smaller cracks and pinholes, until the entire system is airtight. The sealant bonds only at the leaks themselves, so it does not coat the interior walls of your ducts or restrict airflow.
One of the most reassuring aspects of the process is the measurement. Before we begin, our equipment quantifies exactly how much air your ducts are losing. During the sealing, a computer tracks the leakage rate in real time, so you can watch the number drop as the work progresses. When the process is complete, we provide a documented before-and-after comparison. This is not guesswork. You receive verified proof of how much tighter your duct system has become.
Why Skokie Homeowners Benefit From Sealed Ducts
Skokie’s housing stock includes everything from classic brick bungalows and Georgian-style homes to mid-century ranches and newer construction. Many of these homes have had additions, finished basements, or converted attics over the years, and each modification often meant extending or splicing existing ductwork. Those transitions are exactly where leaks tend to develop. When ductwork loses conditioned air into an unfinished attic or a cold crawlspace, your furnace and air conditioner work harder to compensate, and the rooms farthest from the equipment suffer most.
Sealing your ducts with Aeroseal delivers several practical improvements that homeowners notice quickly:
- More even temperatures: Rooms that always ran too hot or too cold begin to hold a consistent temperature because the conditioned air finally reaches them.
- Lower energy bills: When less air is lost to unconditioned spaces, your heating and cooling equipment runs shorter cycles and consumes less energy.
- Improved indoor air quality: Sealed ducts pull in less dust, insulation fibers, and attic or crawlspace air, which means cleaner air circulating through your living spaces.
- Reduced strain on equipment: A furnace or air conditioner that no longer fights against leaky ducts experiences less wear, which can extend its service life.
- Quieter operation: Sealed systems often move air more smoothly, reducing the whistling and rushing sounds that come from pressurized leaks.
These benefits matter most during Chicago-area extremes. In the depth of a January cold snap, every cubic foot of heated air that escapes into an attic is heat you paid for and never felt. During a humid July, leaky return ducts can pull warm, moist air from unconditioned spaces straight into your cooling system, forcing it to work overtime. Aeroseal duct sealing closes those pathways so your equipment can do the job it was designed to do.
The Aeroseal Service Experience With Us
We approach every duct sealing project methodically because the results depend on careful preparation and honest measurement. Here is what you can expect when you schedule Aeroseal duct sealing with All Temp Heating & Air Conditioning:
- Initial assessment: We inspect your duct layout, note accessible connections, and identify any sections that need mechanical repair before sealing begins.
- Baseline measurement: We measure your existing duct leakage so we have a documented starting point and a clear goal.
- System preparation: We protect your furnace coil and other sensitive components, then temporarily seal registers and grilles to isolate the duct system.
- Sealing process: We introduce the aerosolized sealant and monitor the leakage rate as it drops, adjusting as needed until we reach the target.
- Verification and cleanup: We confirm the final leakage number, remove the temporary seals, restore your system, and walk you through the results.
The entire process usually fits within a single day for most homes, and there is no demolition, no tearing open walls, and no mess left behind. Because the sealant cures quickly and is safe for residential environments, your home is ready to use as soon as the work is finished. Many homeowners are surprised at how non-invasive the experience is compared to what they imagine when they hear the words “duct sealing.”
Technical Details Worth Understanding
The sealant used in the Aeroseal process is a water-based, non-toxic polymer that has been tested extensively for residential safety. The particles are small enough to remain suspended in the airstream until they reach a leak, at which point they bond to the metal, fiberglass, or other duct material. The result is a flexible seal that accommodates the natural expansion and contraction ducts experience as temperatures change throughout the year.
Duct leakage is measured in cubic feet per minute at a standard test pressure. A home with severe leakage might lose several hundred cubic feet per minute, while a well-sealed system loses only a fraction of that. When we show you the before-and-after numbers, you are seeing a quantified, verifiable change rather than a vague promise. For homeowners who care about efficiency and long-term performance, this transparency makes the value of the work easy to understand.
Aeroseal also complements other efficiency upgrades. If you are considering a new high-efficiency furnace, an air conditioner replacement, or the addition of an air purifier or humidifier, sealing your ducts first ensures the new equipment performs to its rated potential. There is little sense in installing a premium furnace only to lose a third of its output through leaky ducts. We often recommend duct sealing as a foundational step in a larger comfort and efficiency plan.
