If your HVAC system is running but your home still feels too hot in the summer or too cold in the winter, leaky ductwork might be the reason. At Southport Home Services, we provide expert duct sealing in Madison, WI, to stop air leaks and help your heating and cooling system work more efficiently.

When ducts have gaps or cracks, a significant amount of conditioned air escapes before it ever reaches your living spaces—wasting energy and driving up your utility bills. By sealing these leaks, we make sure the air you’re paying to heat or cool actually stays inside your home, improving comfort and lowering costs.

Signs Your Ducts Are Leaking

Hot/cold rooms, high dust, or whistling at joints
Uneven airflow despite a running system
Higher energy use after equipment upgrades

Sealing complements regular maintenance and can improve comfort in spaces not served well by central air; consider ductless for hard-to-reach zones.

Is Duct Sealing Worth It?

If there are gaps, cracks, or loose connections in your ductwork, that air escapes before it ever reaches your rooms. This makes your HVAC system work overtime to keep up, which leads to higher energy bills and uneven temperatures. Sealing those leaks keeps more of that conditioned air where it belongs—inside your home.

A lot of homeowners don’t realize their ductwork has leaks until they notice cold spots in the winter, hot spots in the summer, or a system that runs all the time but never quite keeps up. Duct sealing helps fix these problems by keeping air moving through your home the way it should.

Beyond comfort and efficiency, leaky ducts can also bring in dust, allergens, and even fumes from places like the attic, garage, or crawl spaces. That air then circulates through your vents, making your home’s air dirtier than it should be. Sealing the leaks helps keep pollutants out, so you and your family can breathe easier.

If you’re searching for “duct sealing near me,” it’s probably because you suspect something’s not right with your ductwork. Signs you might need duct sealing include inconsistent room temperatures, an HVAC system that seems to run constantly, unusually high energy bills, or excessive dust buildup around your vents. Fixing these leaks can make a noticeable difference in your comfort and energy costs.

Sealing your air ducts comes with several key benefits:

Lower energy bills by reducing wasted air

More consistent temperatures

Improved indoor air quality

Less strain on your HVAC system

Increased overall comfort
