Stop Your Attic From Breathing Into Your Bedroom.
Most duct cleaning is like washing your car with the windows down. If your ducts aren’t sealed, you are constantly sucking in attic dust, insulation fibers, and basement moisture.
- Seals leaks up to 5/8″
- Most homes in 4–6 hours
- Non-toxic sealant
What is Aeroseal duct sealing?
Aeroseal is a patented process that seals leaks in ductwork from the inside. The duct system is pressurized and a non-toxic aerosol sealant is blown in; as air escapes through cracks and gaps, the sealant particles collect at the edges and build up until each leak is closed. Computer monitoring measures leakage before and after, and you get a certificate with the results.
Why Aeroseal is our premium service
The Invisible Intruder. Your Home is Sucking in the “Outside”
Conventional cleaning only touches the surface. Without a scientific seal, your HVAC system acts like a vacuum, pulling in allergens from the dark, unconditioned spaces of your home. Here’s how we close that door for good.
Why cleaning has to come first
The sealant needs clean metal to bond to, sealing pressure would blow old dust into your rooms, and brushing ducts after sealing could chip the new seal. That’s why duct cleaning is mandatory immediately before Aeroseal.

The Clean Air Reset Package
This isn’t just a cleaning; it’s a permanent air quality barrier for your family’s health.
Step 1The Clean
We remove the legacy dust. Years of accumulation and biological contaminants are professionally extracted from your system.
Step 2The Seal
We lock the “outside” air out of your “inside” air. Using specialized tech, we create an airtight barrier that prevents re-contamination.
Step 3The Shield
Hospital-grade filtration that finally works because air is actually reaching the filter instead of leaking through the attic.
The 30-Day Satisfaction Promise
“We can’t eliminate 100% of the dust in the world, but we can drastically cut down what gets into your home. If you aren’t completely satisfied with the difference Aeroseal makes in your first 30 days, call us. We will return to inspect our work and make it right.”
How much are your ducts leaking?
Move the sliders to estimate how much conditioned air your ducts lose and what sealing could save each year. Your in-home test replaces these estimates with real measurements.
Gas for the furnace plus electricity for the AC. Your DTE or Consumers Energy bills show it.
Typical homes lose 20–30% of their air through duct leaks. A pre-seal test measures yours exactly.

How we estimate: about 400 CFM of system airflow per ton of capacity and one ton per 600 sq ft; 60% of leaked air is lost outside your living space; sealing closes about 90% of leakage. Planning estimate only. Real savings depend on your measured leakage, where your ducts run and your energy rates.

What exactly is Aeroseal duct sealing?
It’s a specialized process that seals leaks in your home’s ductwork from the inside out using a non-toxic, aerosolized sealant.
How much can I save on my energy bills?
Homeowners typically see a reduction in heating and cooling costs by up to 30% after sealing leaky ducts. Try the savings estimator above for your home.
How long does the process take?
Most residential Aeroseal applications are completed in just 4-6 hours.
Is Aeroseal safe? Is the sealant safe for my family and pets?
Yes! The sealant is non-toxic and has been used in hospitals and schools for years.
How do I know if my ducts need sealing?
If you notice uneven temperatures between rooms, excessive dust, or high energy bills, your ducts are likely leaking.
How much does Aeroseal cost in Macomb County?
Pricing depends on your home’s square footage, the number of HVAC systems and the condition of the ductwork. For the most common Metro Detroit profile (a 1,501–2,500 sq ft ranch, 10–25 years old, one furnace/AC, ducts in good condition) our Clean Air Reset estimate is $2,300 – $3,200, including the mandatory source-removal duct cleaning and Aeroseal installation. Get your estimate.
Why do you require duct cleaning before Aeroseal?
The sealant needs a clean, dust-free surface to bond to, sealing pressure would otherwise blow old dust into your rooms, and cleaning after sealing could chip the new seal. Full explanation.
