Have You Ever Felt Rooms That Never Reach the Right Temperature?
You set your thermostat to a comfortable number, yet the back bedroom stays chilly while the living room feels stuffy. You pay your energy bill each month, but a noticeable portion of that money seems to vanish before it ever warms or cools the spaces where your family spends time. If this describes your Chicago home, the culprit is often hidden inside your walls, ceilings, and crawlspaces: leaky ductwork.
Most homeowners never see their air ducts, so it is easy to forget how much depends on them. The duct system is the delivery network for every bit of heated and cooled air your equipment produces. When that network leaks, the comfort you paid for escapes into attics, basements, and wall cavities instead of reaching your rooms. That is where Aeroseal Duct Sealing comes in, and it is one of the most effective ways we help Chicago families solve stubborn comfort and efficiency problems.
What Aeroseal Duct Sealing Actually Does
Aeroseal is a computer-controlled process that seals duct leaks from the inside out. Rather than crawling through your home to hand-apply mastic or tape to every accessible joint, the Aeroseal method uses an aerosolized sealant that is pushed through your duct system under gentle pressure. As the sealant particles reach a leak, they collect at the edges of the gap and bond together until the opening is closed. The result is a duct system that is measurably tighter, often reaching leakage reductions that hand-sealing simply cannot match.
The reason this matters so much is that traditional duct sealing can only reach the joints a technician can physically touch. Many leaks hide behind drywall, above finished ceilings, or deep inside framed chases where no hand can reach. Aeroseal travels wherever the air travels, so it seals the leaks you could never get to otherwise. At All Temp Heating & Air Conditioning, we appreciate this technology because it delivers results that are documented with before-and-after data, not guesswork.
The Step-by-Step Process We Follow
We believe you should understand exactly what happens in your home during an Aeroseal service. Here is how our team approaches the work from beginning to end:
- Initial evaluation: We inspect your duct system, review your comfort complaints, and identify signs of leakage such as uneven room temperatures, excessive dust, or high energy bills.
- System preparation: We temporarily block your registers and grilles, then isolate the furnace and air conditioning coil so the sealant only travels through the ductwork itself.
- Baseline measurement: We use calibrated equipment to measure your current duct leakage. This gives us a starting number that proves how much improvement the process delivers.
- Sealing process: The Aeroseal machine introduces the aerosolized sealant under controlled pressure. Over the course of the treatment, the software tracks leakage in real time as the openings close.
- Final verification: Once sealing is complete, we take another measurement and provide you with a report that shows the difference between where your ducts started and where they finished.
This methodical approach removes the uncertainty that comes with older sealing methods. You do not have to take our word that the ducts are tighter, because the numbers speak for themselves. Many Chicago homes we treat see dramatic reductions in duct leakage, which translates directly into rooms that finally hold the temperature you set.
Technical Details Worth Understanding
Duct leakage is measured in cubic feet per minute (CFM) at a reference pressure. A typical older home can lose a substantial share of its conditioned air through duct leaks before Aeroseal treatment. Reducing that loss changes how your entire heating and cooling system behaves. When ducts are tight, your furnace and air conditioner do not have to run as long to satisfy the thermostat, which reduces wear on components such as blower motors, ignitors, and compressors.
The Aeroseal sealant particles are extremely small and remain suspended in the airflow until they reach a leak. Because the sealant only accumulates at the edges of gaps and not on the smooth interior duct walls, the process does not narrow or clog your ducts. The material is designed for use in residential systems and has been tested for indoor air applications. Once cured, the seal remains flexible enough to handle the normal expansion and contraction that ducts experience through Chicago’s temperature swings, from humid summers to bitter winters.
Another technical benefit involves indoor air quality. Leaky return ducts often pull air from attics, crawlspaces, and wall cavities. That means dust, insulation fibers, and other unwanted particles get drawn into your breathing air. Sealing those leaks helps keep your indoor air cleaner, which pairs well with the air purifiers, humidifiers, and ventilation products we offer. A tight duct system lets those accessories perform the way they were designed to perform.
Where Aeroseal Makes the Biggest Difference
Over the years, we have used Aeroseal to solve a wide range of comfort challenges across Chicago, Bolingbrook, Skokie, Evanston, Lincolnwood, Morton Grove, Niles, Park Ridge, Woodridge, and Darien, IL and the surrounding communities. Some of the most common situations where this service delivers clear value include:
- Two-story homes with a hot upstairs: When the second floor never cools properly in summer, duct leakage in the attic is frequently the reason. Sealing those runs helps balance temperatures between floors.
- Older bungalows and remodeled homes: Additions and renovations often leave behind duct connections that were never sealed correctly. Aeroseal reaches those hidden gaps without tearing into finished walls.
- High energy bills with no clear cause: If your equipment is relatively new but your bills stay high, escaping conditioned air is a likely explanation.
- Excessive dust and allergy concerns: Sealing return leaks reduces the amount of attic and crawlspace debris pulled into your living areas.
These scenarios appear again and again in the homes we serve, and Aeroseal addresses the root cause rather than masking the symptom. Adding a bigger furnace or a more powerful air conditioner rarely fixes a leaky duct problem. Sealing the ducts first ensures that whatever equipment you own works to its full potential.
