Frequently Asked Questions

Please reach us at sales@insulationco.com if you cannot find an answer to your question.

Duct sealing involves locating and sealing leaks, cracks, and gaps in your home’s ductwork to prevent air loss. It improves energy efficiency, keeps temperatures consistent, enhances indoor air quality, and helps your HVAC system last longer. 


Signs of leaky ducts include:


  • Uneven room temperatures or hot/cold spots
  • High heating and cooling bills 
  • Excessive dust or poor air quality
  • Weak airflow from vents
  • Noisy ductwork 


If you notice any of these, a duct inspection can confirm if sealing is needed.


 On average, 20–30% of conditioned air escapes through leaks in duct systems. This makes your HVAC system work harder, wasting energy and increasing costs. 


 Most residential duct sealing projects are completed in one day. The exact time depends on the size of your home, condition of the ductwork, and number of leaks found. 


No — our process is clean and minimally invasive. We seal your ducts from inside your crawl space, attic, or basement without damaging walls or ceilings. 


 When done professionally, duct sealing can last 10 years or longer. At Insulation Co Inc, we back our work with a 10-year workmanship warranty for peace of mind 


 Yes. Sealing your ducts prevents dust, allergens, mold spores, and pests from entering your ductwork and circulating through your home, creating a cleaner, healthier environment. 


Homeowners typically save up to 20–30% on heating and cooling costs after sealing leaks. The exact savings depend on the extent of leakage and your HVAC usage.
