What Is Air Sealing vs. Duct Sealing
Wondering what the difference is between air sealing and duct sealing? You’re not alone! Many Colorado homeowners confuse the two, but each plays a distinct role in your home’s comfort and efficiency. Air sealing refers to sealing up the cracks, gaps, and holes in your home’s exterior—think around windows, doors, attics, and basements. This helps prevent outside air from sneaking in and conditioned air from escaping, especially in extreme weather.
Duct sealing, on the other hand, targets the hidden network of air ducts that deliver heated or cooled air throughout your home. Over time, duct joints can loosen and develop leaks—sometimes causing 25% to 40% of your heated or cooled air to be lost before it even reaches your living spaces. At Mountain Air Comfort Systems, we tackle both. While air sealing improves your home’s envelope, Aeroseal duct sealing directly improves your HVAC system’s performance. Together, they make your home much more efficient and comfortable year-round.
Benefits of Aeroseal Duct Sealing
Have you ever noticed one room being too hot while another feels like a freezer? Or maybe your energy bill keeps creeping higher even though you haven’t changed your thermostat settings. These are common symptoms of leaky ducts, and they’re more common than you might think. Studies show that most homes have duct leakage of between 25% and 40%, causing HVAC systems to work overtime. Fortunately, there’s a smart fix—Aeroseal duct sealing from Mountain Air Comfort Systems.
- Improved Energy Efficiency: Aeroseal significantly reduces energy loss by sealing gaps in your ductwork. This leads to lower energy usage and utility bills.
- Enhanced Comfort: Say goodbye to hot or cold spots! Properly sealed ducts help maintain consistent temperatures throughout your home.
- Better Indoor Air Quality: Leaky ducts can pull dust, allergens, and even mold spores into your home. Aeroseal minimizes this by sealing the leaks at the source.
- Cost Savings: Reduced energy waste means you’ll save money every month. Over time, the service pays for itself.
- Increased System Lifespan: Less strain on your HVAC system means fewer repairs and a longer life for your heating and cooling equipment.
The Aeroseal formula is non-toxic and safe for families and pets. It works by releasing microscopic sealing particles that find and plug leaks from the inside of your ducts. Best of all, it’s backed by a 10-year guarantee—though studies show results often last much longer.
Signs You Need To Schedule a Duct Sealing Service with Us
Is your HVAC system not performing like it used to? Many homeowners assume the issue lies in the furnace or AC, but often the real problem is hidden behind the walls.

How Often Do You Need Duct Sealing Services
Wondering how often you should have your ducts sealed? Great question—and the answer depends on a few factors. On average, duct sealing lasts around 10 years, especially when you use a proven technology like Aeroseal. However, homes with older ductwork, poor insulation, or major remodels may need service sooner. If you’ve never had your ducts inspected or it’s been a decade or more, it’s probably time for a check-up.
At Mountain Air Comfort Systems, we recommend scheduling an inspection as part of your HVAC maintenance routine. Even minor leaks can add up to big energy losses over time. If you’re part of our Peak Program maintenance agreement, duct evaluations are easy to bundle in. And remember, duct sealing isn’t just about energy savings—it’s about getting the most comfort from the system you’ve already invested in. A sealed system works smarter, not harder, saving you money and reducing wear and tear.
