Higher Utility Bills
Escaping conditioned air forces your system to run longer to reach and maintain the temperature on your thermostat.

Aeroseal Duct Sealing for a More Comfortable Home
Uneven temperatures, excess dust, and surprisingly high energy bills can all point to air leaking from ductwork hidden inside your walls. State Automatic Heating & Cooling seals those hard-to-reach leaks from the inside out with proven Aeroseal® technology.

Stop Paying to Heat and Cool Unused Space
Most homes in Batavia—even newer construction—can lose a meaningful share of heated or cooled air through leaks in the duct system. That conditioned air escapes into attics, basements, and crawl spaces instead of reaching the rooms where you need it.
Aeroseal precisely measures and seals those leaks, helping your HVAC system deliver more of the comfort you already pay for. Unlike manual tape-and-mastic repairs, the process reaches inaccessible connections behind walls and ceilings.
Why it matters: Leaky return ducts can also pull dust, allergens, insulation particles, and other pollutants into the air circulating through your home.
The hidden impact
What Leaky Ducts Can Cost Your Home
Duct leakage affects more than efficiency. It can change how your home feels, what your family breathes, and how hard your heating and cooling equipment must work.
Uneven Temperatures
Rooms farther from the HVAC unit can stay too hot in summer or too cold in winter when air is lost along the way.
Poor Indoor Air Quality
Return-side leaks can draw dust, allergens, insulation, and mold spores from unconditioned areas into your breathable air.
More Equipment Strain
Longer run times accelerate wear on heating and air-conditioning equipment and may shorten system life.
Weak Airflow
Leaks reduce the volume of conditioned air arriving at supply registers, making the whole system feel less effective.
Potential Backdrafting
In some homes, pressure imbalances caused by duct leakage can contribute to backdrafting around combustion appliances.
A precise, measured solution
How Aeroseal Seals Ducts from Within
Aeroseal uses a non-toxic, UL-tested aerosol sealant and computer-controlled monitoring to find and close leaks throughout the duct system—even in places technicians cannot reach by hand.
-
1
Prepare
Registers and return grilles are temporarily blocked, your home is protected, and the duct system is readied for testing.
-
2
Measure
Computer-controlled equipment pressurizes the ducts and records the precise amount of air leakage before sealing.
-
3
Seal
Aerosolized polymer particles travel through the ducts and collect only at cracks, holes, and misaligned connections.
-
4
Monitor
Your certified technician tracks the leakage reduction in real time as openings are sealed from the inside.
-
5
Certify
A post-seal test verifies the improvement, and you receive a detailed report showing your before-and-after results.

Common questions
Aeroseal Duct Sealing FAQ
Helpful answers for Batavia homeowners considering professional duct sealing.
How long does the Aeroseal process take?
For most Batavia homes, setup, sealing, testing, and cleanup can be completed in one day—typically within 4 to 8 hours, depending on the size and complexity of the duct system.
Is the Aeroseal sealant safe for my family and pets?
Yes. The Aeroseal sealant is water-based, non-toxic, and very low in VOCs. It is UL Listed for smoke and flame spread and has been used for years in homes, schools, and hospitals. There is no lingering odor after the process.
How much duct leakage is considered normal?
Many homes lose 20% to 40% of conditioned air through duct leakage. Aeroseal is designed to reduce leakage dramatically—often by more than 90%—and bring the system much closer to industry best-practice levels.
Can Aeroseal close very large holes?
Aeroseal can effectively seal leaks up to 5/8 of an inch. Very large openings, disconnected sections, or major physical damage may need a manual repair before or alongside the Aeroseal application. Our technicians identify those conditions during the assessment.
