Air Duct Sealing

Top-Rated Duct Sealing Services in Des Moines, Iowa

If parts of your home never seem to stay comfortable or your energy bills keep climbing, leaky air ducts might be the cause. Most homeowners in Des Moines don’t think about their ductwork, but it plays a big role in how well your HVAC system works, and in your home’s indoor air quality. At Bell Brothers, we help families across Central Iowa save energy, improve airflow, and get more life out of their heating and cooling systems with professional duct sealing.

Why Leaky Ducts Are a Problem

Leaky ducts can cause big problems, even if you can’t see them. Small cracks and gaps let heated or cooled air escape before it reaches your rooms. That wasted air makes your HVAC system work harder and longer than it needs to.

Here’s what that means for your home:

• Rooms that are too hot or too cold
• Higher energy bills every month
• Extra wear on your HVAC equipment
• More dust, allergens, and outdoor air getting in

Many homes in Des Moines and the surrounding area lose 20 to 30 percent of their conditioned air through duct leaks. That’s energy you’re paying for but not getting.

How Professional Duct Sealing Works

At Bell Brothers, we start by finding all the leaks in your ducts using specialized tests. Then we seal those leaks with strong materials like mastic sealant or foil tape. Sometimes, for hard-to-reach spots, we use pressurized aerosol sealing, such as Aeroseal.

We also recommend air duct cleaning before sealing if your ductwork is especially dusty or contaminated, so your system runs cleaner and more efficiently from the start.

This isn’t a quick fix. We see duct sealing as part of making your whole home run smarter and more efficiently. When ducts are sealed right, your HVAC system delivers steady comfort to every room without working overtime.

Benefits of Duct Sealing

Duct sealing is one of the smartest upgrades you can make to your home. It might not be flashy, but it pays off with real, lasting benefits:

• Lower monthly energy bills
• More even heating and cooling throughout your home
• Less dust and allergens in the air
• Quieter HVAC operation
• A longer life for your system since it doesn’t have to work so hard

For many Des Moines homeowners, duct sealing pays for itself in just a couple of seasons. It’s a simple step toward a more comfortable, efficient home.
