The Hidden Efficiency Problem Inside Your Walls
Most Lincolnwood homeowners think about their furnace or air conditioner when a room feels uncomfortable, but the ductwork carrying that conditioned air often deserves the blame. Industry studies show that the average home loses 20 to 30 percent of the air moving through its duct system to leaks, gaps, and poor connections hidden inside walls, floors, and attics. That is heated or cooled air you paid for, escaping into spaces you never occupy.
Aeroseal duct sealing solves this problem from the inside out, and at All Temp Heating & Air Conditioning we use it to help families across Lincolnwood get more comfort and lower energy waste from equipment they already own. Instead of tearing open walls to reach every joint, the Aeroseal process seals leaks from within the duct system itself, reaching spots that traditional hand-sealing methods simply cannot access.
What Aeroseal Duct Sealing Actually Is
Aeroseal is a computer-monitored sealing technology that closes duct leaks by pushing an aerosolized sealant through the pressurized duct system. The sealant particles stay suspended in the moving air until they reach a leak. At the edge of a gap, the particles cling to one another and to the duct material, gradually building a durable seal across openings up to 5/8 of an inch wide. The process fills the leaks rather than coating the inside of the ducts, so airflow capacity is preserved.
The material itself is a water-based, non-toxic polymer that has been used safely in homes, schools, and commercial buildings for years. Once cured, it forms a flexible seal that holds up against the constant pressure changes and temperature swings a Lincolnwood duct system experiences through hot summers and cold winters. When our team at All Temp Heating & Air Conditioning performs the service, we are addressing the whole distribution network, not just the connections we can reach by hand.
Common Questions Lincolnwood Homeowners Ask
Many people first hear about Aeroseal when they are frustrated with a specific comfort problem. The most frequent question we hear is whether it will fix uneven temperatures between rooms. In many homes, the answer is yes, because leaky ducts often starve the rooms farthest from the furnace while wasting air near the equipment. Sealing the system restores balanced pressure so each register delivers the airflow it was designed to move.
Another common concern is disruption. Homeowners picture crews cutting into ceilings and drywall. The Aeroseal method avoids most of that because the sealant travels to the leaks through the ducts themselves. We prepare the system, run the process, and then remove our equipment, leaving your home intact. A third frequent question involves measurable results, and this is where the technology stands apart. The equipment records leakage before and after sealing, so you receive documented proof of how much tighter your duct system became.
Our Step-by-Step Sealing Process
When you schedule Aeroseal duct sealing with All Temp Heating & Air Conditioning, we follow a careful sequence to protect your home and produce reliable results. Every step is designed to give the sealant the best possible conditions to find and close leaks completely.
- System inspection and preparation: We examine the ductwork, cover the registers and grilles temporarily, and protect the furnace coil and other sensitive components so the sealant only travels where it is needed.
- Baseline leakage measurement: We pressurize the duct system and measure the existing leakage rate in cubic feet per minute, giving us a starting number to compare against.
- Aerosol sealing: The sealant is introduced into the pressurized ducts, where the particles move toward and accumulate at each leak until the openings are closed.
- Live monitoring: Throughout the process, the computer tracks the falling leakage rate in real time, so we can see the seals forming and know when the system has reached its tightest achievable point.
- Final verification and cleanup: We record the post-sealing leakage number, remove the covers and equipment, and restore your registers so the home is ready to use.
The entire visit typically takes a portion of a single day for a standard residential system, though larger or more complex duct layouts may require additional time. Our courteous, fast, and friendly staff handles the setup and cleanup so your daily routine faces minimal interruption.
Technical Details That Affect Your Results
The performance of any duct-sealing project depends on the condition of the system going in. Aeroseal is engineered to close individual gaps up to roughly 5/8 of an inch, so a duct with a disconnected section or a large hole may need a physical repair first before the aerosol phase begins. During our inspection we identify these situations and address them so the sealing process can do its job effectively.
Duct material also matters. The technology works across sheet metal, flex duct, duct board, and combinations of these, which is helpful in Lincolnwood homes that have been remodeled or expanded over the decades. Static pressure is another factor we watch carefully, because a system that is too restrictive can strain the blower motor. By balancing leakage reduction with proper airflow, we protect the equipment while improving distribution. Because the process is computer-monitored, we can document that your system stays within healthy pressure ranges rather than simply sealing it as tight as physically possible.
Where Aeroseal Makes the Biggest Difference
Sealed ductwork benefits nearly every home, but certain situations see especially strong improvements. Older Lincolnwood bungalows and multi-level houses with long duct runs often suffer the most from leakage, and these are the homes where residents notice the sharpest change in comfort after sealing. New additions tied into an existing duct system are another frequent case, since the added length and connections can introduce leaks that starve older rooms.
Beyond comfort, tight ducts improve indoor air quality by keeping dust, insulation fibers, and attic or crawlspace air from being drawn into the airstream through leaks. Families dealing with allergies, lingering odors, or excess dust often pair duct sealing with the air purifiers, humidifiers, and ventilation equipment that All Temp Heating & Air Conditioning also installs and services. Homeowners planning a furnace or air conditioner upgrade gain the most when the ducts are sealed at the same time, because the new equipment can then deliver its full rated capacity instead of wasting output on leaks.

Getting Started With Duct Sealing
The best first step is a conversation about the comfort issues you are experiencing, whether that is a stubborn cold room, rising utility bills, or dust that returns no matter how often you clean. From there we can inspect your duct system, explain what we find, and recommend whether Aeroseal sealing, physical repairs, or a combination will serve your home best. Because the process produces documented before-and-after leakage numbers, you will see exactly what your investment accomplished.
